Vestiture composed of coarse stiff and suberect squamules. Male.— Slightly smaller 
than biarmata but similar, oblong-oval, moderately convex, testaceous, feebly 
shining, the bristles short and abundant; head rather small, feebly concave, the 
eyes moderate ; clypeus triangularly reflexed at each side ; prothorax nearly one-

narrowly sinuato-truncate ; punctures moderately fine, deep and quite demise 
elytra not quite one-half longer than wide ; less than twice as long as the^pro- 
thorax and somewhat wider, feebly rugulose, minutely and rather closely punc¬

Brachycis, gen. nov. 
The chief peculiarities of the single type of this genus are the short 
and suboval form, very short, transversely excavated prosternum and ob¬ 
solescent side margin of the prothorax at the rounded and obtuse apical 
angles. The antennal club is strongly developed, as long as the pre¬ 
ceding six joints combined and has the sensitive apical pores small but 
deep and bristling with white setae, thus leading up to the remarkable 
Plesiocis which follows. The maxillary palpi are rather slender and 
acutely pointed, and the anterior tibiae are finely, acutely and almost 
perpendicularly produced externally in a well-marked process. Sexual 
characters are wanting in the single specimen before me, which is prob¬ 
ably a female: — 
Broad, moderately convex, oblong-oval, piceous, the elytra, legs and antennal shaft 
paler rufo-tes'aceous; body clothed above with stiff pale and erect setce, moder* 
ate in length and density, uniformly distributed ; head rather small, the eyes mod¬ 
erate ; cl)peus simple, subtruncate; prothorax two-thirds wider than loDg,
