“ The male has much the appearance of the female, the eyes are broadly contiguous, leaving a small vertical triangle which is largely occupied by the ocelli; the lateral thoracic lines in this sex are dark brown and therefore are not such a contrast to the bright green thorax as in the female.
I had some trouble in locating the genus of this species by Dr. Williston’s key. The species is not elongate, but of much the same form as Microcrysa polita. A comparison was made with the type.

“ Head conically produced. Front in the female noticeably wider than the eye, in the male about half as wide as in the female. Antennae three-jointed, first and second joints about equal in length, third much longer than the other two together and composed of six rings. Posterior orbits wide in both sexes, but widest in the female, scutellum without spines, four posterior veins arising from the discal cell, abdomen short and broad, nearly circular in outline.
Named for Akron, Ohio, in which vicinity I have procured many rare species. ”

“ In this respect the plant is as striking as any of the so-called compass plants, although the plane in which the leaves lie may be in any direction. Another interesting adaptation is the drooping of the top of the young plant. The entire inflorescence nods at first and finally the individual heads, but one by one these assume the upright position as the flowers begin to open.
J. H. S. Winter Adaptation of Opuntia.—The Ohio species of cactus, Opuntia humifusa Raf., has an interesting habit which seems to be a protective measure against cold. ”

“ The lateral margins of the segments of the abdomen are black between the yellow markings, and there is no connection between the yellow markings on the abdomen.
A female specimen taken by E. J. Oslar at Boulder, Colorado, August 19, 1899.
In many respects this species agrees with Osten Sacken’s decem-maculatus, but it cannot be that species as the markings are very different. Aside from the hairy eyes it appears to belong to Euparyphus. The third joint of the antennae is composed of six rings with the last ring the longest. ”

“ In one case only did merely one leaf and two flowers occur; often but one flower develops though two leaves occur as usual; in a few cases a single small leaf was seen on a pedicel. A more common teratological variation was the elongation of the axis at the usual point of insertion of the flowers and involucral leaves, often distantly separating the leaves with their axillary flowers; in one case the distance between the points of insertion of the leaves was nearly two inches. The sepals are occasionally excessively numerous. ”

“ Jour. of Sci. 11:191–199, 1901, discusses the names applied to the formations of the Ohio Coal measures. The following names are proposed.
The Philadelphia Fleabane (Erigeron philadelphicus L.) is one of our interesting spring plants and will repay careful study. The leaves of the stem in most individuals have a decided polarity and for the most part are twisted so as to stand in a single plane. ”

“ The University of Vienna ranks among the first in the advantages offered to medical students. The hospitals of the city are noteworthy on account of the large number of cases and the great variety of diseases treated. The numerous holidays observed in Vienna seriously interrupt college work. ”

“ Individuals are taken nearly every Autumn in the basement of the Biological Hall while they are seeking shelter. A specimen taken thus had many characteristics in common with xiphias Cope and it is doubtful how valid xiphias is, as a species. ”

“ This beautiful moth is one of the rather common species belonging to the group of silkmaking Lepidoptera. The moths appear in May or June. The female is light rusty brown and drab with a darker area across the middle of the wings, while the males are much darker, nearly black, and differ further from the females in the shape of the wings and markings as shown in the figures. ”

“ This is a common species in southern Ohio. Specimens may be found resting on the upper side of leaves and are easily approached. In the female the white fronted line which Loew mentions is very conspicuous and extends from one eye to the other above the antennae. ”

“ Marys (Auglaize Co.) , Nos. 31–48; from Steubenville (Jefferson Co.) , Nos. 49–65; from West Mansfield (Logan Co.) , Nos. 66–76; from Rendville (Perry Co.) , Nos. 77–88; and from Columbus, Nos. 89–100. The number of stems to each plant is given in the second column; then follow in order the number of flowers to each stem, the number of simple leaves with length of their petioles in millimeters, the number of compound leaves with length (also in millimeters) of their petioles and finally of their petiolules.
TABULATION.
Ohio Naturalist. ”

“ From the above tabulation it may be seen that of the plants selected at random for examination 51 per cent. of the stems have three flowers and 49 per cent. have four or more; 10 per cent. have simple involucral leaves only, 44 per cent. have both simple and compound, and 46 per cent. have only compound involucrate leaves. ”
