EEOTYLID.E. 255 



very shining nor so clearly alutaceous as is the thorax ; the suture and margins are 

 bordered by a very fine impressed line close to their edge, the former is depressed, and 

 the latter are not at all expanded. The under surface is im punctate, and there are no 

 coxal lines. The prosternum is simple, i. e. not carinate nor elevated in front. 



The discovery of a species of Cr/clomorphus so far north, and at such an elevation, is 

 interesting, as the genus has not, so far as I am aware, been recorded previously from 

 the northern continent.

To the localities given, add : — Mexico, Teapa in Tabasco (//. H. Smith). 

 One small example, apparently referable to this species. 



PLASTOCOCCUS (to follow the genus Mgithus, p. 92). 



Corpus suborbiculare, gibboso-convexum, eoccinelliforme. Pronotum perbreve, valde arcuatum ; prosternum 

 aequale, haud carinatum ; metasternum lineis coxalibus integris elevatis. Elytrorum marginibua modice 

 explanatis, epipleuris declivis. Caput in prothorace receptum, oculis leviter granulatis ; antennae breves, 

 clava laxe formata quadriarticulata, baud multo incrassata ; palpi labiales articulo ultimo valde securi- 

 formi. 



The above name is proposed for a very Coccinellid-looking species of Erotylidse, 

 which with no very decided characters is yet not to be associated with any described 

 genus. It is perhaps most nearly allied to Coccimorphus and JEgithus. 



l. Plastococcus atricinctus. 



Rufo-ferrugineus, supra sanguineus, capite, pLothorace (basi excepta) elytrorumque marginibus late, ad apicem 

 latiore, nigris ; elytris vage seriatim punctatis, interstitiis disperse punctulatis. Long. 3f-4 millim.

The disc of the elytra, the scutellum, and the extreme base of the thorax are 

 blood-red ; the head and rest of the thorax are black and smooth ; the thorax is short 

 and arcuate, formed exactly as in Chilocorus. The antenna? are shorter than the head 

 and thorax together ; they are obscurely yellow, with a blackish club. The palpi 

 externally are dark. The front and sides of the thorax are margined by a very fine 

 line ; the base is not margined. The elytra are oval and slightly cordate, smooth and 

 shining, with seven or eight series of distinct punctures, and with confused punctures on 

 the sides and at the apex. The underside and legs are entirely rich tawny-ferruginous, 

 and the true epipleural fold of the elytra is of the same colour, the strongly inclined outer 

 margin being black. The whole form of this insect, and its colour, is so remarkably 

 like that of a Chilocorus that, but for the stouter and apparently four-jointed tarsi, the 

 somewhat stouter antennae, the absence of abdominal coxal fossettes, and the serially 

 punctate elytra, it might readily be taken for a member of that genus. 



A considerable series of specimens was obtained by Mr. Champion.
