the elytra. There is a slight frontal carina and the base of the thorax opposite the 

 scutellum is subcarinately elevated. 



4. Dromaeolus cinerascens. 



Dromceolus cinerascens, de Bonv. Mon. p. 224, t. 9. fig. 5 \ 

 Hab. Mexico, Teapa (coll. Chevrolat 1 ). 



Evidently closely allied to D. tristis, and with a feeble frontal carina. The form of 

 the thorax, on which de Bonvouloir places some reliance for their separation, is purely 

 sexual. I have not seen an example of this species. 



5. Dromaeolus properns. 



Similar in form and in most of its structural characters to D. tristis. Thorax considerably wider than long, 

 gradually narrowed to the apex, disc convex, closely and rather coarsely punctate, a distinct longitudinal 

 impression at the base, surface cinereo-pubescent ; elytra narrowly cinereo-pubescent at the base, the 

 pubescence extending a short distance along the suture and sides ; body beneath less shining than above 

 and more conspicuously cinereo-pubescent ; abdomen closely punctate. 



Length 4 millim. 



Hab. Panama, Bugaba (Champion). 



Easily known from D. tristis and D. cinerascens by the very distinctly impressed line 



near the middle of the base of the thorax.

6. Dromaeolus sallaei. 



Dromaolus sallei, de Bonv. Mon. p. 220, t. 9. fig. 2 \ 

 Hab. Mexico 1 , Cordova (Salle). 



The type of this species has the grey pubescence conspicuous on the thorax and on 

 the base of the elytra, where it forms rather a broad band, the posterior border curving 

 from the suture backward along the side ; the apical fourth is also similarly pubescent. 

 The figure above cited gives rather a false idea of the species. 



7. Dromaeolus variegatus. (Tab. X. fig. 10.) 



Dromaeolus variegatus, de Bonv. Mon. p. 222, t. 9. fig. 3 1 . 



Hab. Guatemala, Sinanja in Vera Paz (Champion). — Amazons, Ega K 



Similar in form to I), sallcei, but with the sides and base only of the thorax cinereo- 

 pubescent. The elytral ornamentation is similar, except that the basal space extends 

 narrowly along the suture to near the middle. In the figure given by de Bonvouloir, 

 the parts most darkly shaded are those most densely cinereo-pubescent. 



8. Dromaeolus ornatulus. (Tab. X. fig., 11.) 



Oblong, moderately convex, piceous-black, slightly shining, surface pubescent, forming a design : antennas 

 rather stout, closely articulated, not serrate, piceous ; head densely punctate, sparsely cinereo-pubescent,
