256 MEMOIRS ON THE COLEOPTERA 



Tribe PCECILOSOMINI. 



Pyrodes Serv. 



The following species is allied to marginatus White: 



*Pyrodes cervicalis n. sp. Male moderately narrow and feebly con- 

 vex, densely sculptured and but feebly shining, obscure viridi-cupreous, 

 the elytra obscure green, frequently suffused with obscure cupreous, the 

 side margin narrowly and inconstantly brighter cupreous, the suture and 

 base never cupreous, concolorous; head much longer than wide, broadly 

 and very deeply furrowed, obsolescently and narrowly toward base; 

 tempora parallel, nearly straight, twice as long as the eyes and a little 

 less prominent; antennae a fourth longer than the body, slender, the third 

 joint almost as long as the next two combined, obsoletely and not densely 

 sculptured; prothorax, excluding the spine, slightly less than twice as 

 wide as long, the truncate base and apex equal; sides sinuously diverging 

 from the apex to the apex of the very acute lateral spine, slightly behind 

 the middle, thence still more sinuous and converging to the base; surface 

 coarsely, confusedly punctate, broadly and feebly impressed medially; 

 scutellum moderate, as long as wide, pointed, finely and variably sculp- 

 tured, subglabrous, with a fine median stria; elytra three-fifths to three- 

 fourths longer than wide, gradually narrowed from base to the obtusely 

 rounded apex, one-half wider than the prothorax, excluding the spines, 

 the surface even, densely, subvermicularly puncto-rugose; humeri widely 

 exposed at base and rather prominent; under surface cupreous, the 

 abdomen brighter and more polished. Female wanting. Length 23.5- 

 27.0 mm.; width 8.2-9.6 mm. Honduras. Four specimens. 



Differs from marginatus in the absence of cupreous elytral mar- 

 gins, except very finely and inconstantly externally, and in the 

 cupreous under surface, among other characters. The fifth ventral 

 is shallowly but sharply sinuate medially at apex. 



Subfamily CERAMBYCIN.E. 



Tribe ASEMINI. 



In this tribe and in some genera of the Callidiini as well, though 

 not so evidently in most of the latter, the second antennal joint is 

 remarkably developed in a relative sense, sometimes being not so 

 very notably shorter than the third; this is a highly distinctive 

 character in this part of the Cerambycinae, though reappearing in 

 some Clytids and several Lepturids, isolating the Asemini among 

 the other tribes in this vicinity. The genera are few in number 

 and not very strongly accentuated.
