Mr. Waterhouse exhibited a specimen of Psammodius porcicollis and a specimen 
of Onthophilus exaratus, and read the following notes respecting them :— 
“The specimen of Psammodits porcicollis I found mixed, in Kirby’s British col- 
lection, with the Psammodius sulcicollis, which it greatly resembles ; the specimen of 
Onthophilus exaratus I have had for many years in my own British collection, where 
it stood with a specimen of Onthophilus sulcatus, and was supposed to be the same 
species ; the two insects in all probability having never been compared till within the 
last few days, when, having determined to clean them, and mount them on card, I 
then perceived that they were distinct species. The history of the specimen is un- 
known to me, but I believe it was given me as the O. sulcatus. Both the insects 
exhibited, it wonld appear, are known only as inhabitants of South Europe. It is 
hoped that this notice will induce our Entomologists to examine their British col- 
lections, with the view of ascertaining whether they contain these species, and can 
furnish us with any information respecting them. 
“ Psammodius porcicullis (Aphodius porcicollis, I/liger, Magazin fiir Insectenkunde, 
ii. p. 195, 2, 1803) has the same thickly tuberculated head, the transverse ridges on 
the thorax, and strongly sulcated elytra, as in P. sulcicollis ; its colouring, moreover, 
is the same, being pitchy black, with the legs and fore part of the head dull rufous ; 
but it differs in being decidedly larger. The oblique ridges seen on the head of P. 
-sulcicollis, and which converge and meet at an angle near the hinder part of the head, 
are scarcely to be traced in P. porcicollis, nor are the large punctures which are 
visible in the former insect on the back of the head. The thorax is relatively more
