 somewhat triangular, mark on the metapleurae above the coxae, yellow. Abdomen 

 longish, cylindrical at the apex; black, the base and apex of the segments fulvous;

 hue, the areolet narrower, the lateral nervures united at the top ; the yellow on the 

 mesopleura narrower ; there is only a narrow oblique line on the metapleura, the hind 

 coxae are entirely black, except at the apex, and an oval mark at the base on the 

 outer side. 



11. Mesoleptus guatemalensis.

Long. 13 millim. 



Hab. Guatemala, Purula in Vera Paz (Champion). 



Antennae as long as the body; inclining to fuscous on the under side, especially 

 towards the apex; densely covered with a blackish pile; third joint as long as the- 

 fourth and fifth together; the last joint as long as the preceding two together; there 

 are forty-eight joints in all. Head punctured, covered with longish fuscous hair; face 

 broadly projecting in the middle ; clypeus also projecting, clearly separated, the apex 

 rounded ; ocelli placed on the top of the head, the front ocellus placed not much before 

 the two posterior ones ; immediately behind these latter the head bends in towards the 

 front ocellus (the edges of this indentation have an indistinct border, and it does not 

 reach to the bottom of the head) ; above the antennae the front is deeply excavated,, 

 and (immediately above each antenna) a somewhat triangular plate-like tubercle pro- 

 ceeds from the eye, extending backwards to the back of the excavated part. Thorax 

 densely pilose, closely punctured all over (except the mesopleurae) ; a broad horizontal 

 line on the side of the pronotum, a mark above this on the mesonotum, the tegulae, the 

 tubercle below them, a mark on the mesopleurae (narrowed on the lower side behind), a 

 smaller mark beneath the hind wings, the sides and the extreme apex of the scutellum,
