females of such strongly developed forms as pulverea and Har- 

 fordi. The antennal club is much shorter, more compact and oval. 

 The anterior tibiae are stouter and with more strongly developed 

 external teeth. The vestiture is very much shorter, finer, and 

 sparser, so that the general color is darker. 



The species of Thyce are nocturnal, being abundantly attracted 

 by bright lights at certain seasons of the year. 



T. squamicollis Lee. — The female of this species is much larger 

 than the male, but is almost precisely similar in vestiture. TLe 

 pronotum in both sexes is very sparsely clothed with small, closely 

 recumbent, squamiform hairs which are slightly denser along a 

 narrow median line, as is usual throughout the genus ; the lateral 

 vittae are, however, not definite. The name is therefore somewhat 

 inappropriate. In the male the antennal club is nearly three-fourths 

 as long as the stem, and in the female only one-half as long as the 

 latter, oval and more compact. 



Although the upper surface is more than usually glabrous, the 

 long dense silken pubescence of the under surface is as well developed 

 as in any other species. 



T. pulTerea n. sp. — Form elongate-oval, convex ; elytra and abdomen 

 dark reddish-brown ; head and prothorax darker, piceous, the latter clothed 

 moderately densely with small robust recumbent hairs, and longer erect pubes- 

 cence ; elytra and abdomen very densely covered with minute, recumbent, 

 squamiform hairs ; remainder of the under surface with long very dense 

 silky pubescence ; mesosternal parapleurse, hypomera, and exposed surface of 

 maxillse devoid of long erect pubescence, but having whiter, dense and recum- 

 bent, squamiform hairs, a small indefinite spot at the sides of each abdominal 

 segment also whiter and denser, remaining vestiture cinereous. Head wider 

 than long; clypeus concave, truncate and very feebly sinuate in the middle, 

 the angles slightly rounded, the base very slightly narrower ; antennal club 

 as long as the stem ; last joint of the maxillary palpus nearly one-half longer 

 than the preceding together, and fully three-fourths as long as the antennal 

 club, rather robust, apex oblique but not deflexed and with a small circular 

 truncation, the groove very deep, widening toward base, entire. Prothorax 

 one-half wider than long ; sides broadly angulate, the angles rounded ; basal 

 angles obtuse and rounded, apical obtuse but not rounded ; apex very feebly 

 emarginate, one-half as wide as the base, the latter broadly angulate, the 

 angle broadly rounded ; disk convex, finely, feebly and densely punctate. 

 Scutellum white, more densely pubescent. Elytra nearly one-half longer than 

 wide, widest near the middle, nearly one- third wider than the prothorax; 

 sides very feebly arcuate ; apex broadly sinuate ; humeri slightly tumid ; 

 apical umbones very feeble ; disk with the most feeble and indefinite traces of 

 fine costse, very finely, feebly and densely punctate. Pygidium one-third wider
