XEW CERAMBYCID BEETLES FISHER 203 



This species is allied to ornatus Fisher, but it differs from that 

 species in having an oblique, dark brown pubescent fascia on the 

 elytra. 



LEPTOSTYLUS PLANICOLLIS, new species 



Small, elongate, moderately flattened above, brownish yellow, 

 densely clothed with white and pale yellow pubescence, and incon- 

 spicuously ornamented with darker pubescence. 



Head with the front quadrate, slightly convex, feebly depressed 

 between the antennal tubercles, which are moderately elevated and 

 widely separated, with a narrow, longitudinal groove extending from 

 occiput to epistoma; surface indistinctly punctate, densely, irregu- 

 larly clothed with rather short, recumbent, white and pale yellow 

 pubescence intermixed, nearly concealing the surface ; eyes separated 

 from each other on the top by twice the width of the upper lobe. 

 Antenna slightly longer than the body, variegated with white and 

 brown pubescence, the outer joints feebly annulated with brown 

 pubescence. 



Pronotum two-thirds wider than long, slightly narrower at base 

 than at apex, widest at basal third ; sides feebly, obliquely expanded 

 to basal third, then strongly, arcuately narrowed to near the base, 

 parallel and narrowly constricted at base; disk even, feebly, nar- 

 rowly, transversely depressed along base; surface indistinctly punc- 

 tate, densely clothed with rather short, recumbent, wdiite and pale 

 yellow pubescence intermixed. Scutellum broadly triangular, rather 

 narrowly rounded at apex, densely pubescent. 



Elytra three-fourths longer than wide, slightly wider than prono- 

 tum at basal third; humeri not prominent; sides parallel to behind 

 middle, then arcuately narrowed to the tips, which are separately 

 narrowly rounded; disk even, without distinct tubercles; surface 

 coarsely, irregularly punctate basally, the punctures becoming obso- 

 lete toward apices, densely clothed with moderately long, recumbent, 

 white and pale yellow pubescence, with numerous small, round, ir- 

 regularly distributed, brown pubescent spots, and each elytron with 

 a large, elongate, more or less conspicuous, brownish spot on external 

 half of disk, the spot extending from basal third to apical fourth, 

 and more distinct on inner margin. 



Beneath feebly granulose, rather densely clothed with long, recum- 

 bent, whitish pubescence, the legs slightly variegated with wdiite and 

 brown pubescence; femora strongly pedunculate; prosternal process 

 two-thirds as wide as coxal cavity. 



Length, 4.25 mm ; width, 1.75 mm. 



Type locality. — Montego Bay, Jamaica.
