base. The abdomen appears to be similar in structure in the sexes, the 

 fifth segment ogival and longer than the three preceding combined. 

 The prothorax is as wide as the elytra or very nearly, short and trans- 

 verse, with the fine intromarginal line receding from the edge at the 

 apical, as well as the basal, angles, and the scutellum is well developed 

 and a little longer than wide. Our species may be defined as fol- 

 lows : — 



Elytra black throughout ' 2 



Elytra castaneous 3 



Elytra and entire body pale testaceous 4 



2 — Head and sides of the pronotum pale in the male, entirely black in the female ; 

 legs red, the femora sometimes picescent ; head and pronotum finely, sparsely 

 punctate. Length 1. 3-I.4 mm.; width I.o-I.l mm. Pennsylvania, North 



Carolina ( Ashville) and Texas (Austin) pusillus Lee. 



Var. A — Similar but slightly larger and with the punctures of the pronotum 

 more distinct ; body and legs black. Southern States.. . .puncticollis Lee. 

 Head pale in the male, the pronotum black throughout, with distinct but sparse punc- 

 tuation ; legs red. Length 1. 15-1.3 mm.; width 0.85-I.0 mm. California 



(southern) and Arizona (Tucson) sonoricus, sp. now 



3 — Castaneous ; middle of the prothorax and a narrow space at the base of the elytra 

 piceous ; head and legs yellow ; pronotum with a few scattered punctures near 

 the middle. Length [1.5 mm]. Sta. Catahna Island, coast of Southern Cali- 

 fornia cataUna? Horn 



4 — Similar to pusillus in form but very small and entirely testaceous. Length 

 [0.8 mm]. Florida (Sand Point) pal I id us Lee. 



I have seen no representative of puncticollis, catalince ox pallidas. 

 It is quite possible that the first may be a perfectly distinct species, as 

 the length is given .07 inch by LeConte. 



SCYMNILLINI. 



In abdominal structure this tribe, which in some respects may be 

 allied to the Ortaliini, resembles the preceding and departs widely 

 from the Hyperaspini or Scymnini ; the ogival fifth segment is, however, 

 shorter than in (Eneini, and is generally but little longer than the two 

 preceding together, perfectly similar in the sexes, except that the fifth 

 segment is more broady rounded and a little shorter in the male. The 

 body is oval, small to very minute in size, more or less pubescent or 

 setulose, with the head strongly deflexed and deeply inserted in the 

 prothorax, the latter obviously narrower than the elytra, abruptly so in 

 Zagloba, deeply emarginate at apex, with narrowly reflexed side margins, 

 the base feebly lobed before the scutellum, which is moderate in devel-
