This genus includes three species which resemble Phyma/odes in the 
rounded sides of prothorax, slightly tapering elytra and clavate femora 
- but differing in the broad prosternum and enclosed hind coxz. They 
'. are easily separated by their colors as follows.

This species is entirely black. the thorax thickly clothed with long 
white hair and ornamented with two smooth, strongly elevated callosities. 
The elytra are black, coriaceous at tip and sides and have an indistinct 
patch of white or grav pubescence about one third from base with scme- 
times a still more indistinct patch behind this, ‘The posterior thighs are 
scarcely clavate. The antennz are very slender and short; in G' one-

This species is black, the thorax has three indistinct See longi- 
tudinal elevations, and is otherwise densely punctured; the elytra are 
shining violet blue, finely and densely punctured; the femora are simple, 
neither anterior nor posieiey being clavate. Length .75 inch. = 19 mm,

This species is.very variable in color. The body is black and the 
thorax carries five slightly elevated callosities.. The thighs are as in 
bajulus clavate except the posterior. The antennz are longer and in the 
female quite strongly serrate. The normal color of the elytra is bright 
yellow with apical fourth and a medial spot black. The yellow is at 
times however nearly red and the spot is extremely variable in size and 
shape. Length .30to .45 inch, =7to12mm, Habitat, Maine to

This genus, containing many species, in addition to characters of 
table is distinguished from Cadidiwm which the species often closely re- 
semble, by the labial palpi being much shorter than the maxillary. The
