Glen, during the expedition of August, 1905. Easily recognized 
by the lobe on each side of the fifth ventral segment and by the 
spinose antennae. 
Hoplisoides tricolor (Cresson). 
1868. Gorytes tricolor Cresson, Transactions of the American Ento- 
mological Society, i, p. 380. 
1895. Gorytes tricolor Fox, Proceedings of the Academy of Natural 
Sciences of Philadelphia, p. 526. 
This peculiar insect is found in some numbers at Glen, and has 
also been taken at McCook, during the month of August. It is 
quite variable as to the amount of red and black. 
Hoplisoides pygidialis ( Fox). 
1895. Gorytes pygidialis Fox, Proceedings of the Academy of Natural 
Sciences of Philadelphia, p. 528. 
Taken at Glen, August 14, 1905. It may be readily recognized 
by the peculiarly distinct and regular puncturation. 
Hoplisoides microcephalus (Handlirsch). 
1888. Gorytes nvicrocephalus Handlirsch, Sitzungsberichte der Akad- 
emte der Wissenschaften, Wien, xcvii, p. 405. 
1895. Gorytes microcephalus Fox, Proceedings of the Academy of 
Natural Sciences of Philadelphia, p. 529. 
Also taken at Glen, August, 1906. The spinose or dentate an- 
tennae and the tufts of long hair at the corners of the clypeus 
serve to readily identify this species. 
Hoplisoides barbatulus (Handlirsch). 
1888. Gorytes barbatulus Handlirsch, Sitzungsberichte der Akademie 
der Wissenschaften, Wien, xcvii, p. 408.

Sciences of Philadelphia, p. 530. 
Two females, Glen, August 13 and 20, 1906; one male and one 
female, Pine Ridge, July. The female I believe is hitherto un- 
described. It is very much like the male, but differs in having 
a much broader face, and a much broader and shorter clypeus, 
which is at least four times as broad as long in the middle, and 
has a number of long, stiff, dark hairs on the disk; the antennae 
are ferruginous and yellow basally; both the anterior and pos- 
terior eye margins are reddish yellow, and in one specimen these 
fuse to form a reddish line across the occiput just back of the
