oiie-fourtli from apex witliin the costa; body beneath more shining than above . 
prosternum sparsely punctate, lobe deeply ernarginate. intercoxal process broad, 
very obtuse at tip, propleune densely punctate and clothed with white pubes- 
cence ; metasternum densely punctate at the sides and with the episternum and 
coxal plate clothed with white pubescence. Abdomen not closely punctate, ex- 
cept at the sides of the first segment, the suture between it and the second w'ell 
marked at the sides, segments two to five with a pubescent space at sides placed 
transversely, vertical portion of the segments with white pubescence : last seg- 
ment serrate at sides near apex; pygidium coarsely punctate, the oarina not 
projecting; claw's cleft behind the apex, forming an acute tooth. Length .40 — 
.50 inch. ; 10 — 13 mm. 
Sexual characters. — Although both sexes are before me, tliere seem 
to he no external characters by means of which they can be se})a- 
rated, excepting that all the tibite of the male have a short mucro 
at tip on tlie inner apical side, while in the female tliey are simple. 
Variations. — Beyond the color nothing has been observed. The 
pubescent spots may be abraded, although they seem unusually per- 
sistent. The smaller spots, jiosterior to the base, form on the elytra 
an elongate hexagon. 
Hab. — Oregon and northern California ; Boise City, Idaho ; Luna, 
N. Mex. ; following the distribution of Melanophila miranda.
