3 — Metacoxal arcs extending to the middle of the segment, black, the elytra slightly 

 piceous, each with two large nubilous pale areas ; prothorax short and transverse, 

 abruptly and distinctly narrower than the elytra, the sides feebly convergent and 

 nearly straight to beyond the middle ; elytra finely, sparsely, somewhat unequally 

 punctulate, one-half wider than the prothorax. Length 1.7 mm.; width 1. 25 

 mm. California ( Sta. Cruz Mts ) ornata Horn 



Metacoxal arcs extending distinctly beyond the middle ; elytral sculpture similar. . .4 



4 — Prothorax only slightly and not very abruptly narrower than the elytra, the sides 

 strongly convergent and evenly, strongly arcuate from base to apex; elytra oval, 

 but little more than a third wider than the prothorax and rather longer than 

 wide in the female, shorter in the male, piceous, each with two large nubilous 

 pale areas. Length 1. 6-1. 8 mm.; width 1.25 mm. California (exact locality 

 not recorded) laiicollis, sp. now 



Prothorax abruptly very much narrower than the base of the elytra, much smaller than 

 in latu lis, the sides rather strongly convergent and nearly straight to the 

 middle, then broadly rounded ; elytra pale testaceous, with a large basal sub- 

 quadrate brown area on the suture which is emarginate at each side, at least two- 

 thirds wider than the prothorax. Length 1.7 mm.; width 1.3 mm, California 

 (Sonoma Co. ) orbipennis, sp. nov.-* 



5 — Elongate-oval, moderately convex, the stiff whitish pubescence of the upper sur- 

 face very conspicuous ; head and prothorax throughout pale rufo-testaceous, the 

 elytra black ; legs and abdomen testaceous, the latter blackish toward base ; eyes 

 narrow, not at all covered by the pronotum ; prothorax only slightly and not very 

 abruptly narrower than the elytra, the sides feebly convergent and arcuate, the 

 apex much less' deeply emarginate than in the preceding species; elytra longer 

 than wide, rather narrowly rounded behind, finely, not densely and somewhat 

 unequally punctate; metacoxal plates extending far beyond the middle. 

 Length 1.5 mm.; width 0.9 mm. Florida (near Palm Beach ibicolor, sp. nov. 



6 — Very broadly rounded, moderately convex ; head and prothorax testaceous, the 

 latter broadly and nubilously blackish toward the middle, abruptly and con- 

 spicuously narrower than the elytra, with the sides feebly convergent, rounded at 

 apex, the latter deeply emarginate ; elytra black, shining, scarcely visibly punc- 

 tulate, not as long as wide, rather narrowly rounded at tip ; under surface piceous 

 or paler, the legs testaceous ; metacoxal arcs extending but slightly beyond the 

 middle. Length 1. 35-1. 6 mm.; width 1. 05-1. 2 mm. Texas (Brownsville) —

The members of this genus are all small, and number among them 

 some of the most minute of the Coccinellidae. The surface is ap- 

 parently glabrous, but minute hairs can generally be discovered on the 

 head or pronotum, and the elytra usually have some very small, erect 

 and widely scattered setae. The epistoma is very short before the 

 antennae. The three species before me may be thus outlined : —
