“ We do not seem to understand each other as to the Cryptus aphidium of Fab. I either have misstated my opinion or forgotten the reasons I gave for thinking it of any other genus than Microgaster. I have looked and I think I doubted whether Linnaeus insect which is the same as Fabricius's be not a Microgaster as stated in my Guide - be good enough to give me your opinion. ..... I am sure any observations of yours will be highly valued by the men of science whom I have the pleasure of knowing. I hope therefore you will when you have leisure undertake the Conspectus of the Hymenoptera pupivora. ”

“ Fearing it may be too late for Baillieres parcel I remain in haste, yours most sincerely, J. Curtis.
Feb. 23rd Curtis to A.H.H. I really despair of ever sending you this sheet but I shall make an effort. I regret in publishing the genus Phytomyza it entirely escaped me that all your contributions were not contained in your first list and not finding any species there I have unfortunately not noticed it in my paper. I am happy to say that I have just finished putting your contributions into my cabinet and shall therefore have the full use of them and not overlook anything. ”

“ I regret exceedingly that I have pubd. the genus Microgaster as your russatus is a fine species, Microleptus splendidus is most valuable as it sets me right Drapetis will be pubd. on the 1st March. Tryphon and Xylota 1st April Melous and Scathophagus 1st May. ..... Mr. Dale says if you will send a Guide marked he will be most happy to transmit to you some new Haustellata. ..... I am delighted to hear that you have discovered the antennae of Pulexo I assure you I spent 3 days in examining and dissecting P.canis and could not discover them. ..... ”
