pubescence, &c. it agrees very nearly with Leconte’s description of £. murinus, an 
insect inhabiting Georgia and Alabama. 
2. Eurygenius lanuginosus. (Tab. IX. fig. 3, ¢.) 
Brownish-black, the front of the head and the elytra obscure castaneous, thickly clothed with long, coarse, 
decumbent whitish pubescence, amongst which arise very many long, semierect, similarly-coloured 
bristly hairs, the decumbent pubescence on the elytra here and there forming rather large spots, the 
head and prothorax opaque, the elytra shining. Head very densely and moderately coarsely punctured, 
canaliculate behind; eyes large, prominent, coarsely granulated, unemarginate in front ; antenne testa- 
ceous, moderately slender, joint 3 much longer than 2, joints 8-10 comparatively elongate, not much 
widened towards their apex (11 missing); prothorax not very convex, about as long as broad, the sides 
broadly rounded before the middle, almost straight behind, and rather abruptly constricted before 
the apex, the disc transversely depressed in front and canaliculate thence to the base, the base grooved 
within on either side laterally, the surface very densely but not coarsely punctured (the sculpture much 
hidden by the pubescence); elytra impressed with deep, coarse, closely placed, oblong punctures (which 
are here and there confluent), the punctures gradually becoming finer and more shallow towards the apex, 
those on the apical portion of the disc finer and more scattered than those at the sides; beneath densely 
and finely punctured and thickly pubescent; legs coarsely and roughly punctured, thickly clothed with 
very long bristly whitish hairs, piceous, the base of the femora and the tibie in great part reddish- 
brown; fifth ventral segment broadly semicircularly emarginate, the sides not produced, in the male. 
Length 83 millim. (<¢.) 
Hab. Mrxico, Cordova (Sallé). 
One male example. The differently sculptured thorax and elytra (the punctures on 
the latter becoming gradually, not abruptly, finer beyond the middle, and also less close 
on this part), the testaceous antenne, the more numerous and much longer semierect 
hairs (in addition to the still coarser decumbent pubescence) of the upper surface, and 
the shape of the fifth ventral segment in the male distinguish this insect at once from 
E. mexicanus. The Californian £. constrictus, Lec., is a closely allied species; but, to 
judge from the brief description, L. lanuginosus is quite distinct from it. 
3. Kurygenius crinitus. 
Brownish-black, the elytra brown with a slight coppery lustre, the entire upper surface clothed with rather 
long, ashy, decumbent pubescence, amongst which arise longer semierect hairs, the decumbent pubescence 
on the elytra here and there forming spots, the head and prothorax opaque, the elytra shining. Head 
very densely but not very coarsely punctured, distinctly canaliculate ; eyes large and prominent, not 
very coarsely granulated, almost unemarginate in front; antenne piceo-testaceous, moderately slender, 
joint 3 considerably longer than 2, 8-10 very little widened towards their apex, 11 one and a half 
times the length of 10; prothorax not longer than broad, somewhat flattened on the disc, the sides 
broadly rounded, converging behind, and feebly constricted immediately before the apex, the disc with a 
fine smooth central line from the base nearly to the apex, and shallowly transversely depressed in front, 
the surface densely and confluently punctured ; elytra very closely and coarsely punctured, the punctures 
gradually becoming finer towards the apex; beneath piceous-brown, shining, coarsely pubescent, thickly 
and coarsely punctured, the venter and the middle of the metasternum much more sparsely so; legs coarsely 
and roughly punctured, clothed with long bristly whitish hairs, piceous, the base of the femora and the 
tibize in great part reddish. . 
Length 64 millim. ( 9.)
