in the other sex the pygidium is a little more strongly and 

 closely punctured, with a faint impression on either side near 

 the apex. In calidus the sex that I regard as male has the 

 pygidium carinate, with sparse fairly strong puncturation ; 

 while in the other sex the pygidium is carinate, with still 

 stronger and conspicuously closer punctures. It should also 

 be noted that in calidus the elytra are transversely thick- 

 ened, quite strongly, close to the apex, while in parvulus there 

 is scarcely any trace of such structure. The trilobed outline 

 of the head is feeble in both species, and not divided, the 

 middle lobe about two-thirds of a lateral lobe in size. I have 

 a specimen from Roebuck Bay too much mutilated to be 

 justifiably described which seems to represent a distinct species 

 very close to calidus.

Easily distinguishable by the characters cited in the 

 tabulation. The trilobed outline of the head is feebly deve- 

 loped and not divided, the middle lobe about two-thirds of a 

 lateral lobe in size. The fine raised lateral edging of the 

 elytra does not continue along the apex, but ends abruptly at 

 the extero-apical corner.
