and unicostata, and possibly Ologlyptus bicarinatus of Champion, 

 may also belong to this genus. The Asida semilcevis of Horn, is 

 appended very doubtfully. 



Group I Type hirsuta Lee. 



Two rather isolated species alone constitute this group so far as 

 known. The body is moderate in size and clothed almost through- 

 out, as well as on the legs and upper surface of the tarsi, with very 

 long erect flexible hairs of pale ashy color, the under surface of the 

 tarsi having shorter though relatively somewhat long stiff dense 

 and more fulvous hairs. The mentum is transversely obtrapezoidal 

 and very loosely fitted, the antennae moderately short and very 

 slender, the prothorax rectilinearly truncate at base with obtuse 

 angles, the elytra devoid of any trace of side margin even at base, 

 the legs moderately long, with the tarsi notably short and slender 

 and with unusually long and slender claws, and the outer edge of 

 the anterior tibiae is not perceptibly serrulate as it is in the next 

 group. The abdomen from base to apex is much longer than all 

 the parts anterior thereto combined. 



Body rather narrow, very convex and subcylindric, blackish-brown in 

 color, the integuments highly polished when clean and without micro- 

 reticulation; vestiture very conspicuous but not dense, cinereous, 

 fine, composed of very long and sparser flying hairs and others of 

 the same general character but shorter and more recurved, forming 

 vague broad vitta? on the elytra; head scarcely at all impressed, 

 finely, sparsely punctulate ; antennae less than one-half longer than the 

 width of the head; eyes very coarsely faceted, transverse, convex, 

 only very feebly sinuate anteriorly; prothorax moderate, two-fifths 

 wider than long, two-thirds as wide as the elytra, parallel, evenly and 

 moderately rounded at the sides throughout the length, the apex 

 feebly sinuate, narrower than the base, with the angles right, not 

 evidently advanced and not blunt, the basal angles obtuse but not 

 rounded ; surface moderately and evenly convex, minutely, notdensely 

 punctate, rather abruptly, deeply, somewhat narrowly concavo- 

 explanate at the sides, the edges reflexed and rather thin; elytra 

 parallel, widest at the middle, three-fifths longer than wide, very 

 obtuse and steeply declivous behind, the apical lobe small but 

 evident, the sides evenly and moderately arcuate, the base trans- 

 versely truncate, with the ends of the basal margin finely dentiform, 

 surface of each with three very broad and feeble tumescent lines, 

 bearing the more numerous vitta-forming short hairs, the punc- 

 tures minute, granuliferous, sparse, still more remote between the 

 vittae; flanks vertical, only moderately deep; abdomen broad, moder-
