EROTYLID^E 169 



*^Egithus rhombifer n. sp. Body broadly rounded, very convex, the 

 elytra cordiform and obliquely pointed behind; color bright red, the entire 

 under surface, excepting the head, broad sides of the prothorax and the 

 wide and basally impressed epipleura, deep black, the narrowly convex 

 median part of the prosternum piceous and the mesosternum between 

 the coxae testaceous; legs and antennse wholly black; head rather more 

 than two-fifths as wide as the prothorax, smooth, the epistoma loosely 

 punctate, the eyes very prominent, the fine side margins above them well 

 developed; antennae a little longer than the head and prothorax, slender, 

 smooth, the third joint as long as the next two, the eighth but little 

 thicker than the seventh, the club subparallel, pubescent and much com- 

 pressed as usual; prothorax nearly three times as wide as the median 

 length, the sides very strongly converging, the apex deeply sinuate; 

 surface broadly flattened laterally, having at the middle from apex to 

 base, a subrhomboidal black area, which is much narrower than long, 

 rounded at the sides, widest near basal fourth and thence rapidly nar- 

 rowed to the middle of the base; scutellum black; elytra widert near basal 

 third, where they are fully four-fifths wider than the prothorax, obliquely 

 and arcuately narrowing to the acutely ogival apex; in profile they are 

 highest at about the middle, almost equally and arcuately sloping thence 

 anteriorly and posteriorly; surface impunctate and with a varnish-like 

 glaze; under surface almost impunctate. Length 10.3 mm.; width 7.8 

 mm. Honduras (San Pedro Sula). A single example. 



In politus Gorh., which this seems to resemble in some features, it 

 may be known by the rhombiform thoracic spot. The prosternum 

 is not produced medially at its anterior margin as described of 

 politus. 



*^)githus binarius n. sp. Broadly rounded, strongly but very evenly 

 convex, red, the elytra alutaceous; pronotum with a small transverse 

 black spot at the middle of the apical margin and a larger and less trans- 

 verse spot at base, just before the scutellum, which is black as usual; 

 under surface colored as in the preceding, except that the prosternum is 

 not more pallid in color or elevated and convex medially, its anterior 

 margin not at all produced medially; legs and antennae throughout 

 black; head nearly as in the preceding, except that there is some minute 

 punctulation anteriorly behind the punctate epistoma; antennae with the 

 second joint not as long as the next two, the eighth nearly twice as thick 

 as the seventh and slightly wider than long, shining, the club very densely 

 punctulate, pubescent and opaque, much more densely so than in the 

 preceding; prothorax not so short, barely two and one-half times as wide 

 as the median length, nearly similar in shape but with the surface less 

 flattened laterally; elytra very different, widest at the middle, with the 

 sides almost evenly arcuate, gradually but rapidly converging posteriorly 

 to the very broadly ogival apex; surface in profile evenly convex from base 

 to apex, having some feeble creases; under surface impunctate, shining. 

 Length 10.5-10.7 mm.; width 8.0-8.2 mm. Mexico (Guerrero), Baron. 



The peculiar maculation of the pronotum will easily distinguish
