CEPHAL,OS€Vl?IXlTS Crotcli. 



This genus (lifters from Scyrnniis in having the anterior eoxal cavi- 

 ties open behind. The tliorax is narrower at base than the elyti-a 

 and nuicli more deeply emarginate at apex than in Scymmis. The 

 liead is more deeply inserted, the front vertical, the eyes narrowly 

 oval, rather finely granulate, and in two species with a very feeble 

 impression at the antennal insertion. The antennje are very short 

 and seem to be but 10-jointed. The abdomen has five segments, the 

 sutures distinct ; tarsal claws slightly broadened at base. 



CJrotch gives eleven joints to the antennae, but T have not been 

 able to see more than ten, in which respect Mr. H. C. Fall, of (yali- 

 fornia, adds confirmation from an examination of a species taken by 

 him. 



The species at present known are as follows : 



Elytra not ornate. 

 Body above black ; elytra moderately coarsely, not densely punctate ; eyes with 



slight impression Ziiiiiiierniaiini. 



Body above brownish; elytra very coarsely and densely punctured; eyes 



scarcely visibly impressed occidentalis. 



Klytra with two yellow spots often snffused. 



Elytra not coarsely {)unctate ; eyes distinctly notched omattlS. 



C Kiiiiiiieriiiaiini Cr. — Broadly oval, slightly convex, black, slightly 

 bronzed, pubescence gray and irregular. Head moderately coarsely and not 

 closely punctate. Eyes feebly im])ressed, not twice as long as wide; labrum con- 

 spicuously yellow. Thorax fully three times as wide at base as long at middle, 

 coarsely and closely punctured, densely at the sides, no basal marginal line. 

 Elytra broader at base than the thorax, about one-fourth longer than wide, sur- 

 face more coareely punctate than the thorax, but less closely ; prosternnni short 

 and broad, nearly smooth without elevated lines ; metasternum smooth at middle, 

 punctate at sides; nie.socoxal arc joining the suture one-fourth from the front. 

 Abdomen scarcely punctate, metwcoxal arc entire, half the length of the segment. 

 Legs piceous, tibiae and tarsi paler. Length .06 — .08 inch. ; 1.5 — 2 mm. PI. II, 

 tig. 10. 



Crotch desei'ibes this s|)ecies as dark green, which is the result of 

 slight immaturity with the mixture of slight bronze of the surface 

 and the pale iuiirs. 



The type was collected in Soutli Carolina, others are known to me 

 from District of Columbia and Maryland. 



C OCl*i«leiltalis n. sji. — Oval, slightly oblong, feebly convex, paler i)iceons 

 with grayish jiubescence. Head moderately closely punctate. Thorax three 

 times as wide as long at middle, sides feebly arcuate, surface closely punctate, 

 densely and rather roughly at the sides. Klytra wider at base than the thorax, 

 surface coarsely ami closely i>unctute, roughly near the umboue; prosternnni
