DEOM^EOLUS. 219 



Interocular carina anteriorly elevated, the inner end curving down- 

 ward on the sides of the clypeus ; antennae paler at the base . tetricus. 

 10. Elytra scarcely visibly striate ; antennse and legs ferruginous ; in- 

 terocular carina entire, clypeus not carinate fastidiosus. 



The last five species are very Thambus-like in appearance, while those at the head 

 of the table approach the North -American type. 



1. Dromseolus moerens. 



Oblong, moderately convex, black, sparsely clothed with short, inconspicuous, nearly black pubescence : 

 antennae black, closely articulated, joint three slightly longer than four ; head densely, rather coarsely 

 punctate, a slight depression near the interocular carina, which is entire, clypeus narrow at the base, 

 not carinate ; thorax a little wider than long, gradually narrowed from the hind angles, arcuately in front, 

 disc convex, a slight depression at the basal margin each side of the middle, surface densely punctate, 

 more opaque than the elytra ; elytra finely striate, intervals scarcely convex, moderately closely punctate, 

 the punctures much finer than on the thorax ; body beneath black, moderately shining, closely punctate, 

 finely pubescent. 



Length 4-5-6 millim. 



Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 



Closely related to B. tristis, which it resembles in form, but with uniform pubescence 

 not different from the surface colour. 



2. Dromseolus senilis. 



Oblong, not very convex, narrowed posteriorly, black, subopaque, clothed with cinereous pubescence equally 

 over the entire surface : antennse piceous, feebly serrate, third joint one half longer than the fourth ; head 

 densely punctured and subopaque, a very slight median impressed line in front, interocular carina entire, 

 clypeus moderately separating the antennse at the base, not carinate ; thorax a little broader at the base 

 than long, sides arcuately convergent to the front, disc moderately convex, a short ante-scutellar carina, 

 surface very densely punctate ; elytra distinctly striate, the intervals closely subgranulately punctate, and 

 quite rough at the base ; body beneath very densely punctate and subopaque, abdomen pubescent ; legs 

 piceous. 



Length 4 millim. 



Hab. Guatemala, Zapote (Champion). 



While this species possesses all the characters leading to its reference to B. cinerascens 

 by the table given by de Bonvouloir, the absence of a frontal carina and the presence 

 of a small one at the base of the thorax, together with the uniform pubescence and the 

 more opaque and roughly-sculptured surface, readily distinguish it. 



3. Dromseolus tristis. 



Dromaolus tristis, de Bonv. Mon. p. 223, t. 9. fig. 4 1 . 



Hab. Guatemala, Yzabal (Salle *), Teleman in Vera Paz (Champion) ; Nicaragua, 

 Chontales (Belt). 



Similar in form and vestiture toB. sallcei, hut without a cinereous space at the tip of
