2 — Legs pale and bright flavo-testaceous, the femora black with the apex distinctly 

 and conspicuously pale ; sides of the prothorax nearly continuous and strongly 

 converging 3 



Legs piceo-fuscous, the femora blackish ; body similar in form to the preceding .... 5 



3 — Metacoxal plates shorter, frequently extending much less than half way to the 

 suture ; elytra! punctures moderately close-set, quite strong and distinct, the 

 pubescence short. Length 1.2 mm. ; width 0.8 mm. Europe ; [minimus Payk.j. 



* punctillum Weue 



Metacoxal plates less transverse, extending to or beyond the middle, varying some- 

 what according to the sex of the individual ; body somewhat smaller, with shorter 

 and more transverse prothorax and less conspicuous elytral punctures but longer 

 pubescence 4 



4— Elytral punctures fine but strong and quite sparse. Length 1. 0-1.2 mm. ; width 

 0.75-0.9 mm. Lake Superior to Pennsylvania and Delaware, North Carolina 

 and Kansas puactum Lee. 



Elytral punctures finer, feeble and less sparse ; prothorax slightly more transverse, 

 the body a little more oblong-oval but otherwise extremely similar. Length 

 1. 15 mm. ; width 0.8 mm. Cape of Good Hope (Cape Town).

5 — Elytra very distinctly longer than wide, finely but strongly, sparsely punctured, 

 the pubescence moderately long, recurved as usual. Length 1 .0-1.3 mm - '■>

picipes, sp. nov. 



Elytra not obviously longer than wide ; body smaller and more broadly oval, the pro- 

 thorax shorter and more transverse ; elytral punctures stronger and more close-set.

6 — Legs pale rufo-testaceous throughout ; body evenly oval ; elytral punciures very 

 small and sparse, the pubescence moderately long, recurved as usual. Length 

 0.9mm. ; width 0.72mm. Florida (Haulover near Jupiter Inlet) . . Utilis Horn 



Legs pale testaceous, the femora black except at apex ; body narrower, more elon- 

 gate and more oblong, with much less arcuate sides ; prothorax transverse, with 

 the sides continuous as in utilis but rather less arcuate ; elytral punctures stronger 

 and less sparse, the pubescence nearly similar but somewhat fuscous in color. 

 Length 0.95 mm. ; width 0.7 mm. Texas (Columbus) atomus, sp. nov. 



Punetum and picipes are both abundant, and the difference in the 

 coloration of the legs, noted in the table, appears to be constant ; in 

 picipes the form is a trifle more elongate and- more narrowly oval ; 

 jejunus, five specimens of which were taken by the writer about sixteen 

 years ago, resembles punetum so closely that the two could scarcely be 

 distinguished unless examined in series. Gilvifrons Miill., which is 

 associated with punctillum in the European catalogues, I have not seen, 

 but the genus Stethorus, which is there considered a subgenus of 

 Scymnus, is irt no wise to be so regarded ; it is a perfectly valid genus.
