the notch falling off more obliquely. In the insect exhibited I do not perceire the 

 differences in the punctuation alluded to, nor those in the structure of the antennie. 



"Again, a species of Homalota is distinguished from H. analis by Thomson (see 

 his ' Skiindinaviens Coleopteia,' ii. 294), under the name Amisclia platvcephala, by 

 having the abdominal plate in the male deeply emarginaie, and in the female trun- 

 cate, so fir agreeing with our insect. But A. platycephala is said to be broader than 

 H. analis, less convex, and with the fovea on the thorax obsolete ; the antennae testa- 

 ceous at the base, and the eljtra obscure testaceous, — distinctions which do not exist 

 in the insect before the Society. I still think it possible that it may be identical both 

 with H. soror and A. platycephala. Thomson says of his species that it is scarce in 

 North Scania, and Kraatz simply informs us that the H. soror was taken by him near 

 Bonn, and he makes no mention of the female. It is probable then that neither of 

 these authors had ample material for arriving at the characters of the species, and 

 that, under more favourable circumstances, their descriptions might have been modi- 

 fied. However this may be, this note is communicated to the Society with the view 

 of eliciting further information respecting those species which are certainly most 

 closely allied to H. analis. The last-mentioned species I have collected in great 

 numbers in various localities, but, amongst eighty specimens rouglily grouped together 

 in my unexamined collection of species of Homalota, I do not appear to possess a 

 single specimen corresponding with the insect from the Hammersmith Marshes, of 

 which my son found and exhibits two dozen specimens, presenting an equal number 

 of males and females. The species then would appear to be very local." 



Paper read. 

 Mr. M'Lachlan read a paper on Anisocentropus, a new genus of exotic Tri- 

 choptera; descriptions were given of five species of that genus, viz., A. illustris, n. sp. 

 (of which specimens were exhibited), A. diiucidus, n. sp,, A. immunis, n. sp., A. lati- 

 fascia. Walk., and A. pjraloides, Walk. To these was added the description of a new 

 species of Dipseudopsis, D. coUaris, from China.
