EPOPTEETTS.— EPHEBTJS. 131 



fossse at the base, fully twice as wide as long; the hinder angles right angles; the 

 upperside is black, but the front angles are widely yellow, this yellow portion having 

 a square projection parallel to the margin just outside the sulci. The elytra are 

 orange-yellow, with the suture at the base widely, an undulate fascia (which looks as 

 if composed of three oblong guttse), a punctiform dot near the shoulder, and an oblong 

 spot common to both elytra on the apex, black ; behind the fascia there is an ill-defined 

 pitchy spot on the suture. The underside and legs are black ; but the sides and tip of 

 the abdomen, the pro- and mesosterna, and the tarsi are reddish-yellow, and the 

 epipleural margins of the elytra are yellow, with the extreme limb dark. 



E. scalaris is allied to E. tigrinus, Gerst., and also rather closely to E. testudinarius, 

 Gorh. It is wider and more convex than the latter, and is distinguished from both by 

 the black legs, the wholly black antenna?, &c. 



A good many specimens were found by Mr. Champion at Bugaba, from one of which 

 the figure is drawn. 



Section B. Body ovate, the thorax more or less narrowed in front. 



5. Epopterus pantherinus. (Tab. VII. fig. 22.) 



Late oblongo-ovatus, fortiter convexus, crebre subtiliter punctatus, nitidus, dilute piceus ; prothoracis margine 

 antico in medio, limbo laterali infra medium, et basali tenuiter nigris ; elytris nigro-retieulatis, macula 

 humerali triramosa, duabus medianis, tribus apicalibus sat magnis, nigro-einctis, pallide flavis ; scutello, 

 antennis (articulis duobus primis exceptis) et tibiarum basi, nigris. Long. 5|-6 millim. 



Eab. Panama, Bugaba, David (Champion). 



This beautiful species is easily distinguished from any other in our district by its 

 convex oval form. In this respect, and also in the three-branched shoulder-mark, it 

 exhibits some affinity with E. ryei, an Amazonian species figured in the ' Endomycici 

 Eecitati.' The three subapical spots are whitish in the specimen from Bugaba, and the 

 two central ones are confluent in the single example from David. The entire limb of 

 the elytra is very narrowly black. 



EPHEBUS. 



Ephebus, Gerstacker, Monogr. Endom. p. 293 (1858) ; Gorham, Endom. Recit. p. 24 ; Chapuis, 

 Gen. des Col. xii. p. 125. 



Ephebus is chiefly distinguished from Stenotarsus by the absence of an impressed line 

 inside the lateral margin of the thorax. Seven species have been described, all from 

 Tropical South America. 



l. Ephebus piceus. (Tab. VIII. fig. l.) 



Breviter oblongus, rufo- piceus, nitidus ; antennis validis, nigris, articulis tribus basalibas runs ; capite minute, 

 prothorace elytrisque parcius distincte, punctatis, his parce rufo-pilosis. Long. 3 millim. 



Eab. Guatemala, Zapote (Champion).
