out, not definitely impressed, the punctures distinct, traceable to 

 the declivity; apical groove of the seventh stria long and strong; 

 foveae approximate; near three and four sevenths. Length (cf 9 ) 

 4.0-4.7 mm.; width 1.5-1.75 mm. Texas (Brownsville), \Yick- 



ham amnicum n. sp. 



Body oblong-suboval, still more convex, shining, black, alutaceous and 

 feebly viridate anteriorly; elytra each with a small pale spot at base, 

 a slender external fascia near basal third, extending to the fourth 

 stria, the line on the eighth interval long, also with a small external 

 fascia at posterior third, broadly united with the large apical pale 

 area; under surface black, the abdomen rufous about the external 

 limb, the legs, hypomera and epipleura pale; head moderate, scarcely 

 more than three-fourths as wide as the prothorax and as wide as 

 the thoracic apex, the sulci parallel, moderately broad and rather 

 deep, the eyes rather prominent; antennae moderately long, fuscous, 

 paler basally, the medial joints between two and three times as long 

 as wide; prothorax two-fifths wider than long, the finely reflexed 

 sides subevenly and strongly rounded to a short and very feeble 

 sinus at the angles, which are sharp and minutely prominent, scarcely 

 more than right, the base notably arcuate, nearly three-fourths the 

 maximum width; impressions very feeble, the stria extremely fine; 

 foveae small, moderately impressed, linear, the carina short and fine; 

 elytra one-half longer than wide, almost one-half wider than the 

 prothorax, gradually parabolic behind, the parallel sides broadly 

 arcuate; striae entire, strong, feebly impressed, but becoming very 

 fine on the declivity; punctures basally rather coarse and perforate; 

 foveae at two and four sevenths; apical groove of the seventh stria 

 short, bearing a single puncture. Length (9) 4-5 mm.; width 1.8 



mm. Texas (without more definite locality) festinans n. sp.

59 Form moderately stout, strongly convex, polished, black, the head 

 not definitely alutaceous; elytra vaguely picescent at tip, the mar- 

 ginal spot near the apex scarcely traceable in strong light; under 

 surface black, the abdomen dull rufous; legs uniform rufous; head 

 well developed, nearly four-fifths as wide as the prothorax, with only 

 moderately prominent eyes, the sulci rather narrow and deep; an- 

 tennae somewhat slender, fuscous, clearer at base, the medial joints 

 scarcely three times as long as wide; prothorax about a third wider 

 than long, the sides evenly and strongly rounded, becoming very 

 feebly sinuate only at the angles, which are not prominent, widest 

 barely before the middle, the margins moderately reflexed; base 

 three-fifths the maximum width; anterior impression subobsolete, 

 the posterior feebly evident, except medially, the stria extremely 

 fine; foveae small, rather deep, narrow and linear, the carina obso- 

 lete; elytra oblong, parallel, one-half longer than wide, three-sevenths 

 wider than the prothorax, circularly rounded at apex; striae rather 

 coarse, feebly impressed, obsolete at apical fourth, the seventh at
