222 SEREICOENIA. 



sparsely towards the apex ; body beneath subopaque, coarsely and closely punctate, cinereo-pubescent ; 

 legs ferruginous ; antennal grooves very narrow, not wider behind. 

 Length 3-3*5 millim. 



Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith). 



By de Bonvouloir's tabular arrangement this insect is related to D. dilutipes ; but 

 the form and the absence of striae associate it with the Thambiform species, of which 

 D.fastidiosus may be considered typical. 



12. DromaBolus suturalis. 



Oblong, moderately convex, piceous-black, shining, thorax opaque ; sparsely cinereo-pubescent, on the elytra 

 more evidently along the side margin and suture ; antennas rufo-testaceous at the base, outer half gradually 

 darker, subserrate, joints three and four equal: head densely punctate and opaque, interocular carina not 

 elevated, ending abruptly at the base of the clypeus, the latter flat, not carinate ; thorax broader at the 

 base than long, much narrowed at the apex, sides sinuate in front of the hind angles, disc convex, densely 

 but not roughly punctate, opaque, a slight depression at the hind angles, surface sparsely cinereo- 

 pubescent ; elytra vaguely striate near the base, surface not closely submuricately punctate, pubescence 

 sparse and piceous, cinereous along the suture and side margin ; body beneath moderately closely punctate, 

 cinereo-pubescent ; femora piceous, tibiae and tarsi rufo-testaceous. 



Length 3 millim. 



Hab. Mexico, Xucumanatlan in Guerrero (H. H. Smith). 



This species is evidently allied to D. funcki ; but differs in having a less prominent 

 interocular carina and the third joint of the antennae not longer than the fourth, and also 

 in the colour of the antennae and the disposition of the cinereous vestiture. The sutural 

 stria is not impressed at the apex as in the following three species. 



13. Dromseolus vanns. 



Similar in form and appearance to D. fastidiosus ( $ ) ; basal joint of the antennas piceous, outer joints brown, 

 third joint distinctly longer than the fourth : head densely punctate, sparsely cinereo-pubescent, front 

 slightly concave, interocular carina somewhat prominent, rather broadly interrupted at the base of the 

 clypeus, this nearly as broad as half the distance to the eye, flat ; thorax broader at the base than long, 

 sides straight and convergent, near the apex arcuate, disc convex, a feeble median longitudinal impression 

 in front of the base, surface moderately shining, closely, not densely punctate, finely sparsely pubescent, 

 cinereous at the sides and base ; elytra vaguely striate at the base only, the sutural stria deepened and 

 broadened at the apex, surface rather closely submuricately punctate, densely and more roughly at the 

 base : body beneath more coarsely and closely punctate than above, somewhat strigose, sparsely pubescent ; 

 femora piceous, tibiae and tarsi pale rufo-testaceous. 



Length 4 millim. 



Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith). 



The elytra are sparsely clothed with a dark pubescence, cinereous along the base, and 

 slightly so along the sides. While it resembles D. fastidiosus, the present species may 

 be known by the interrupted interocular carina, and by the sutural stria being deep and 

 broadened at the apex.
