Notes on tJ/r Tuichopterygia fmiiKl in America hjj tite late

By the Rev. A. Matthews, M.A. 



While my lamented friend, Mr. Crotch, was so actively and so 

 successfully engaged in collecting insects in America, he did nut 

 foi-get the friends whom he had left behind. The sight of a 

 Trichopteryx would no douljt recall to his mind the many hours 

 of interesting study we had spent in each others company, and 

 many an anxious search through the pages of antiquated 

 Entomological works made with unwearied patience for my 

 special benefit. Thus it happened that ^vhatever part of the 

 world might chance to l)e the scene of his explorations, the 

 Trichopterygia were ever in his mind, and the number of these 

 atoms which he possessed at the time of his death proves with 

 wdiat zeal they had been collected. Dr. Le Conte, in whose 

 hands the collections of Mr. Crotch were placed, has with great 

 care grou])ed the various sjjecies and transmitted a large selection 

 of them to me ; by his kind permission, I am now al)le to 

 ])ublish the result of my examination. These collections did 

 not, however, comprise the whole of Mr. Crotch's discoveries in 

 the Trichojjterygia ; he had not been very long in America 

 before he sent to me a few species which he had found in the 

 Eastern States, though I regret to add that the package did not 

 reach me wlien he was alive. In this lot, among many of the 

 forms usual in that region, there were two very interesting new 

 S]jecies ; of these one was a Triehopter/i.r, presenting the very 

 jieculiar form of 7'. mrinlosd but much smaller, and of an 

 intensely dee]) black colour with a shining and almost impunctate 

 surface ; the other was a very small species of iVossidiiu//. 

 P)Oth these have been alreadv doscriljed in " Cistula Eiitomo- 

 logica,"vol. T. ]). 2tt.S, luuler the names of 7'. ///(/'/Y'«6-and Xossii/iviit
