PENTARIA. 253 
2. Pentaria flavipes. 
Moderately elongate, pitchy-black, the elytra usually fuscous or brownish from a little below the base to the 
apex, the labrum and mouth-parts testaceous or fusco-testaceous; the upper surface opaque, finely 
pubescent, the prothorax and elytra very densely transversely strigose. Head comparatively broad ; 
antenne short (not nearly reaching the base of the prothorax when the head is extended), thickening 
outwardly, joints 8-10 strongly transverse, 1-6 testaceous, 7-11 piceous or black ; palpi testaceous, the 
apical joint sometimes darker at the tip; prothorax about one half broader than long, very feebly bisinuate 
at the base, rounded at the sides, the hind angles subrectangular; beneath piceous; legs slender, testaceous, 
the anterior tarsi very feebly dilated in the male; fifth ventral segment similar in both sexes. 
Length 23-25 millim. (¢ Q.) 
Hab. Mexico, Guanajuato (Sal/é). 
Six examples. Smaller and a little less elongate than P. canescens; the antenne 
shorter and with the basal six joints testaceous; the elytra not so black ; the legs more 
slender and entirely testaceous. The male apparently has the head broader than in the 
female, and the anterior tarsi feebly dilated (less so than in P. canescens). P. fuscula, 
Lec., from Texas and New Mexico, seems to be an allied species. 
3. Pentaria brunneipennis. 
Moderately elongate, rather narrow; the head and prothorax piceous ; the elytra reddish-testaceous to about 
one-third from the base, thence to the apex brown, the apical third a little paler in colour, the suture very 
narrowly infuscate ; the upper surface slightly shining, finely pubescent, the prothorax and elytra exceed- 
ingly finely transversely strigose. Head small; antenne rather short (not quite reaching the base of the 
prothorax when the head is extended), thickening outwardly, joints 9 and 10 transverse, 1-6 flavo- 
testaceous, 7-11 piceous; palpi flavo-testaceous ; prothorax about one-third broader than long, bisinuate 
at the base, moderately rounded at the sides, the hind angles rectangular; beneath piceous; legs rather 
stout, testaceous, all the femora piceous, but paler towards the apex, the tarsi slightly infuscate; the hind 
tibize about as long as the three basal joints of the posterior tarsi united, with traces of oblique grooves on 
their outer face. 
Length 24 millim. (9.) 
Hab. Muxico, Chilpancingo (H. H. Smith). 
One female example. Smaller, narrower, and more shining than P. canescens; the 
thorax relatively longer; the elytra brown, this colour becoming more dilute and redder 
in tint towards the base; the transverse strigation of the upper surface less dense. 
4. Pentaria brevicornis. 
Moderately elongate, rather narrow, black, the mouth-parts testaceous ; the upper surface dull, finely pubescent, 
the prothorax and elytra very finely transversely strigose. Head small; antenne very short (reaching very 
little beyond the middle of the prothorax when the head is extended), thickening outwardly, joints 8-10 
transverse, 1-5 testaceous, 6-11 piceous; palpi testaceous; prothorax about one third broader than long, 
the sides somewhat obliquely converging anteriorly and very little rounded, the hind angles rectangular, 
the base a little produced in the middle behind; beneath piceous; legs slender, piceo-testaceous or 
infuscate, the tibie a little lighter. 
Length 23-23 millim. 
Hab. Guatemata, Capetillo, Calderas (Champion). 
Three examples, apparently including both sexes. Smaller, narrower, and more
