7 — Somewhat narrowly and evenly oval, very pale throughout, except beneath, 

 where the body is black, the hypomera, epipleurse, tip of the abdomen and legs 

 pale ; prothorax but little more than twice as wide as long, the sides rather 

 strongly convergent and evenly arcuate, the punctures scarcely visible ; elytra 

 quite closely punctate, the punctures very minute, with larger punctures which 

 tend to lineal arrangement intermingled toward base. Length I.3-I.6 mm. ; 



width 0.9-I. I mm. California and Arizona pallens Lee. 



Broadly oval and more convex, shining, dark rufo-testaceous, the pronotum slightly 

 clouded toward the middle and base ; elytral suture very finely piceous ; body 

 beneath and legs pale, except the post-sterna, parapleurae and abdomen which 

 are black, the latter pale at tip ; head and broad sides of the pronotum paler 

 than the elytra, the prothorax short, nearly three times as wide as long, with 

 moderately converging and feebly arcuate sides, which are not continuous with 

 those of the elytra, the punctures sparse and very minute, closer and distinct to- 

 ward the apical angles ; elytra finely but distinctly, evenly and rather sparsely 

 punctured ; under surface closely punctate, the ventral plates distant from the 

 hind margin of the segment by two-fifths of their own length ; legs rather 



slender. Length 1.6 mm. ; width 1.2 mm. Colorado nugator, sp. nov. 



8 — Form very broadly oval, the elytra not at all longer than wide 9 



Form more narrowly oval, the e'ytra longer than wide 11 



9 — Prothorax entirely orange yellow, a little more than twice as wide as long, the sides 

 evenly arcuate and subcontinuous with those of the elytra, the latter finely but 

 distinctly, not very densely punctate, the pale apical area advancing to apical 

 two-fifths at the sides and beyond apical fourth on the suture ; abdomen and 

 legs throughout pale. Length 1.6 mm.; width I.I mm. Florida (Indian River).

Prothorax partly or complete'y black in color and more transverse IO 



10 — Apex of the fifth ventra' segment very broadly and feebly sinuato-truncate in the 

 male ; pale area of the elytra very constant, extending to about apical sixth or 

 seventh. Length 2.1-2.3111111.; width 1.6 mm. North Carolina, Texas and 



Arizona ; [asitttus Muls.] creperus Mitls. 



Var. A — Nearly similar to creperus but more broadly oval, with a larger thoracic 

 black area and with the apical red area of the elytra smaller, less transverse 

 and more strongly biarcuate at its anterior margin. Length 2.4 mm. ; 



width 1.8 mm. Middle States f raternus Lee. 



Apex of the fifth ventral deeply and evenly sinuate in circu'ar arc with well defined 

 and somewhat prominent, though obtuse, lateral limits ; red area of the elytra 

 extending through apical third to two-fifths ; punctuation distinct and rather 

 sparse ; pronotum red at the sides, more narrowly toward base. Length 2.2-2.4 



mm. ; width 1. 6-1. 7 mm. Florida and Indiana hemorrhous Lee. 



Var. A — Similar to hemorrhous but with the red of the elytra extending well 

 beyond the middle. Length 2 2 mm. ; width 1.5 mm. Kansas. 



divisus, var. nov. 



Var. B — Similar to hemorrhous but larger, the pronotum completely black and 



more densely and distinctly punctured toward the sides ; apical red area 



similar; female only observed. Length 2.7 mm. ; width 1.8 mm. Canada.
