1. Prepopharus duponcheli. (Tab. VI. figg. 17, var. ; 18.) 



Erotylus Dwponchelii, Chevr. Col. Mex. Cent. i. fasc. 4, no. 91 (1834) \ 



Scaphidomorphus Duponchelii, Lac. Monogr. Erotyl. p. 488 2 ; Crotch, Cist. Ent. i. p. 546 3 . 



Prepopharus Duponchelii, Gemm. & Har. Cat. Col. xii. p. 3718. 



Hab. Mexico 123 , Cordova (Edge, Salle), Toxpam, Orizaba, San Andres Tuxtla 

 (SallS); Guatemala, Cerro Zunil, Zapote, San Geronimo, San Juan in Vera Paz, 

 Panima (Champion); Costa Rica, Cache (Rogers); Panama, Bugaba, Volcan de 

 Chiriqui, Caldera (Champion). 



This species is very variable, especially in the markings on the thorax : these normally 

 consist of four black spots — a transverse one in front, just touching the margin, two 

 lateral oblong ones, and a median one on the base — but these are varied, divided, and 

 united in every conceivable way. In the Mexican examples the disc of the thorax is 

 often dark, and the front and lateral margins yellow ; but even then the disc shows 

 some traces of the divisions between the typical spots. Many examples. 



We figure a variety from San Andres Tuxtla and one (more typical) from Caldera. 



2. Prepopharus xanthomelas. (Tab. VI. fig. 12.) 



Scaphidomorphus xanthomelas, Crotch, Cist. Ent. i. pp. 150 1 , 546. 

 Prepopharus xanthomelas, Gemm. & Har. Cat. Col. xii. p. 3718. 



Hab. Nicaragua, Santo Domingo in Chontales (Janson \ Belt) ; Costa Rica, Cache 

 (Bogers). 



3. Prepopharus spilotus. (Tab. VI. fig. 19.) 



Oblongus, ovatus (elytris cordatis), convexus ; antennis, femorum apieibus, tibiis, tarsis elytrorumque punctis in 

 singulis sex (uno basilari, tribus in fasciam angulatam dispositis, duobus post medium obliquis), nigris; 

 elytris punctato-striatis, ad apices lsevibus. Long. 9 millim. 



Hab. Panama, Bugaba (Champion). 



This insect has very close relationship with some Brachyspheni ; but from the scaphi- 

 form shape of the body beneath I think it belongs here. The striae are somewhat 

 gemellate, i. e. the second and third and the fourth and fifth, and these pairs approach 

 at the apex ; but at the base of the elytra the first (or sutural) stria unites with the 

 second, and the third with the fourth. 



Five specimens of this interesting species were captured by Mr. Champion. 



PRIOTELUS. 



Priotelus, Hope, Rev. Zool. 1841, p. 112; Lacordaire, Monogr. Erotyl. p. 493 ; Chapuis, Gen. Col. 

 xii. p. 70 ; Crotch, Cist. Ent. i. p. 550. 



Lacordaire included nine species in this genus, which is characterized by the thinness 

 of the antennae, and their comparative length — in this respect resembling, but often
