9. li. vailUS n. sp. —Ohlon^ oval, moderately convex, pale yellowish testa- 

 ceous, shining, the suture very narrowly infusi'ate behind the middle. Antennfe 

 pale, the outer five joints slightly darker. Head decidedly darker tlian the 

 thorax, smooth. Thorax about one-third wider than long, not narrowed in 

 front, sides very distinctly arcuate, at anterior angles obliquely truncate, basal 

 marginal line entirely wanting, disc moderately convex, surface slightly wrin- 

 kled, the punctures relatively coar.se, but not close. Elytra distinctly wider at 

 base than the thorax, humeri rounded, umbone moderate, sutural angle distinct, 

 but obtuse, disc moderately convex, the punctures moderate, rather closely 

 placed, a little finer at apex, but distinctly impressed throughout. Body beneath 

 and legs similar in color to the upper surface. Abdomen very indistinctly punc- 

 tate. Length .08 inch. ; 2 mm. 



This species is the most distinctly punctate of the ])resent series of 

 pule species, and while a little variable in degree, it is never .so finely 

 punctate as in livens or repandus. 



Occurs in western Texas and at Seligman, Ariz. (Wickham). 



10. Li. occidentalis u. sp. — Oblong oval, feebly convex, yellowish testa- 

 ceous, moderately shining. Anteuuffi pale at basal half, darker externally. 

 Head slightly rutescent, smooth, shining. Thorax one-lialf wider than long, 

 apparently slightly narrowed in front, broadest a little behind the middle, sides 

 arcuate, slightly obliquely truncate at front angles, hind angles very broadly 

 rounded, base truncate at middle aud with an extremely indistinct marginal 

 line, disc moderately convex, the surface very distinctly and moderately closely 

 punctate at base, sparser and fine in front. Elytra distinctly wider at base than 

 the thorax, humeri rounded, umbone not prominent, sutural angle obtusely 

 rounded, disc moderately convex, the punctuation fine and sparse, nearly smooth 

 at apex. Body beneath and posterior femora brownish testaceous, abdomen 

 sometimes piceous, the legs otherwise pale yellowish testaceous. Abdomen very 

 distinctly, but not closely i)unctate. Length .08 — .10 inch. ; 2—2 5 mm. 



Resembles repandiif!, but very distinctly punctate, and with the 

 underside darker, in fully mature specimens nearly black. 



This species has been heretofore considered and determined for 

 several corresi>()ndents as nigripalpis Lee, but an examination of 

 the type of the latter shows it to be at least congeneric with (Mala- 

 cosoma) fuscula Lee (Lyperaltica Crotch) and })robably not specifi- 

 cally different. 



Occurs in Colorado, Utah and Arizona. 



11. It. bicolor n. sp. — Oblong oval, moderately convex, beneath piceous, 

 head and thorax rufotestaceous, elytra and legs yellowish testaceous, surface 

 moderately shining. Antennte pale, slightly darker externally. Head rufotes- 

 taceous, smooth. Thorax one-third wider than long, nut narrowed in front, 

 sides arcuate, distinctly obliquely truncate in front, base truncate at middle, 

 with distinct mai'ginal line, disc convex, sparsely, but distinctly punctate. Ely- 

 tra distinctly wider at base than the thorax, humeri rounded, umbone moderate.
