By the Rev. A. Mattiikws, M.A. 



While my laraenteil friend, Mr. Crotdi, w.is sn aetively and sn 

 successfully engaged in collecting insects in America, he did nut 

 forget the friends whom he had left l)ehind. The sight of a 

 Trichopteryx would no doubt 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 Avorks made with uuAvearied patience for my 

 special benefit. Thus it happened that whatever 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 A\ith 

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

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

 care groiiped the variovis species and transmitted a large selection 

 of them to me ; by his kind permission, I am no^v able to 

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

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

 the Trichopterygia ; 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 jDackage did not 

 reach me when 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 'rricho/)t<u-//.f\ presenting the very 

 peculiar form of 7'. vnriolosd l)ut much smaller, and of an 

 intensely deep black colour with a shining and almost impimctate 

 siu'face ; the other Avas a very small s})ecies of Nossidiuiii. 

 Both these have been ah-eady described in '" Cistula Entomo- 

 logica,"vol. 1. p. :^'.tS. un<ler the names of T. iinrvcnsvaMX Xoftfiidnmi
