median brown vitta extending from the anterior margin to the 

 base. Scutellum triangular, very broadly rounded behind, and the 

 surface flat and very sparsely pubescent. 



Elytra two-thirds longer than wide, and one-fourth wider than 

 the pronotum; humeri rather strongly developed and feebly ele- 

 vated; sides arcuately rounded, more strongly apically, to the tips, 

 which are strongly obliquely truncate internally, with the inner 

 margin feebly, arcuately emarginate, and the exterior angles rather 

 acute and moderately produced; surface uneven, with an oblique 

 impression extending from near the humeri to the suture, rather 

 densely, finely, and irregularly punctate over entire surface, densely 

 clothed with cinereous pubescence, which has a slight brownish 

 tinge in some parts, with numerous irregularly placed tubercles, 

 which are densely clothed with ocherous pubescence, and each elytron 

 with a transverse sinuate brownish-black spot along suture near 

 the middle, a similar but smaller spot behind it situated on middle 

 of disk, and two more or less obsolete elongate spots of the same 

 color near apical fourth, and the apical part more variegated with 

 ocherous pubescence than the basal half. 



Beneath finely, densely punctate, with a few coarser punctures 

 intermixed, and sparsely, irregularly clothed with cinereous and 

 brownish-white pubescence, giving the surface a mottled appearance ; 

 tibiae at apex, last two tarsal joints, and the tarsal claws brown; 

 prosternal process about two-thirds as wide as the coxal cavity; 

 femora strongly clavate. 



Length, 11.5 mm.; width, 4.50 mm. 



Type locality. — " Porto Rico Exp. Sta." (Rio Piedras, Porto 

 Rico.) 



Type.— C&t. No. 28391, U.S.N.M. 



Described from a single male, labeled simply " Porto Rico Exp. 

 Sta." There is also a very small specimen received from the Ameri- 

 can Museum of Natural History, collected at Aibonito, Porto Rico, 

 between July 14 and 17, 1914, which I have placed under this 

 species. This specimen is only 6 mm. long, but is nearly identical 

 in all other respects with the type. It probably represents a speci- 

 men which has developed prematurely on account of insufficient food. 



This species can be separated from the other known West Indian 

 species of the genus by its extremely long antennae. 



LEPTGSTYLUS ALBOFASCIATUS, new species 



Form shorter and more convex than poeyi Fisher, reddish black, 

 rather densely clothed with pale brown and brownish-black pubes- 

 ence, with a narrow W-shaped mark of cinereous pubescence along 

 the suture at the middle, common to both elj'^tra, with the base 

 pointed backward; mandibles black, with the base reddish; palpi 

 vellow^ish brown.
