tatives in the tropics of both hemispheres, as well as one or two in the United States of 
North America. 
Hileusis is a very distinct genus, though its characters have been only very incom- 
pletely exposed. The front cox are extremely short, and the thoracic pieces adjoining 
them exhibit a very peculiar structure: the side-piece forms only a short obtuse pro- 
jection behind the coxa, but in front of it there is an additional piece, which from its 
position makes the lateral portion of the coxa appear very largely exposed and visible. 
I expect it will prove that this peculiar piece is really the trochantin that has become 
enlarged, and attached to the prosternum in such a manner as to form part of the outer 
skeleton of the insect.

1. Eleusis bicolor.

Notices ent. ii. p. 34°.

Var. dwisa. Elytris dimidio basali testaceo. (Tab. XIX. fig. 16.) 
Hab. Guatemaa, Cerro Zunil, Zapote, Senahu, San Gerénimo (Champion). 
We figure an example of the variety divisa ; it is apparently commoner in Guatemala 
than the typical form; intermediate examples occur but rarely. Fauvel states that the 
female has the head suborbiculate, but this is not the case; some examples are only 
half the size of others, and these have perhaps a rather smaller head than is due merely 
to diminution of general stature, but the head is always straight at the sides and 
suboblong in shape. 
2. Kleusis rufula. 
Rufo-testacea ; elytris versus apicem fuscis ; capite oblongo, subtiliter strigoso, inter antennas punctis majoribus 
obsoletis impressis. 
Long. 44-5 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
. This species is very closely allied to H. bicolor, but, besides being only half the size, 
has the head and thorax red, the sculpture much finer, and the elytra a little shorter. 
The vertex has an obsolete fovea. The thorax is about as long as broad ; it has a well- 
marked depression on the front margin on each side; and the sides are straight to 
behind the middle, thence much narrowed to the base. The elytra are very densely and 
finely strigose. The surface is very shining, and has no distinct punctures except those 
near the front of the head between the antenne. Five examples.
