sparingly but coarsely punctured, the apical segments with 

 only sparing and fine punctures. Legs dark yellow ; tarsi 

 rather long, with the lobes broad. Genje coarsely and 

 rather closely punctured ; underside of hind body very

Tapajos; a single individual, which is I believe a female. 



24. Stenvs parviceps, n. sp. (Sect. II. B, Er.) Niger, 

 nitidus, sujira parcius albido-pubescens, antennis palpisqiie 

 testaceis, illarum clava obscuriore ; pedibus infuscato-rufis, 

 femoribus tibiisque basi quam apice dilutioribus ; capita 

 tliorace vix latiore, bisidcato ; elytris thorace longioribus, 

 crebre fortiter punctatis ; abdomine apicem versus angus-

Antenna moderately long, yelloAV, with the club darker ; 

 3rd joint a good deal longer than 4th. Palpi yellow, the 

 apical joint darker than the preceding one. Head much 

 narrower than the elytra, and scarcely broader than the 

 tliorax, not excavate, but distinctly bisulcate ; the surface 

 irregularly punctured, as when viewed from the front, the 

 middle and some spaces near the eyes appear like shining 

 spots. Thorax scarcely longer than broad, greatly nar- 

 rower than the elytra, the sides not rounded but a little 

 narrower at the base than in front ; the surface coarsely, 

 moderately closely punctured, the punctures absent from 

 a very small space behind the middle. Elytra much 

 longer and broader than the thorax, the shoulders rec- 

 tangular and a little elevated, coarsely and closely but not 

 densely punctured. Hind body a good deal narrowed 

 towards the extremity, rather coarsely punctured ; the 

 punctures on the apical segments much finer than at the 

 base, the punctures rather close, the pubescence very fine 

 and scanty. Base of femora reddish, extremity infuscate ; 

 front coxffi reddish, hind ones pitchy; tibiae yellowish, in- 

 fuscate towards the extremity; tarsi infiiscate-ycllovv : 

 mider surface deeply, coarsely and densely punctured, 

 opaque and with the white pubescence elongate and con- 

 spicuous. 



The male on the underside exhibits a notch at the ex- 

 tremity of the 7 th segment ; it is, however, much con- 

 cealed by the dense, fine, elongate, pale pubescence, wdiicli 

 covers the middle of the segment ; the 6th segment is also 

 densely piibescent along the middle, and its hind margin 

 is slightly notched at the extremity.
