68 PROCEEDINGS OP THE NATIONAL MUSEUM vol.80 



Elytra elongate, nearly parallel, and broadly rounded or subtruncate 

 at apices. Abdomen elongate, and the segments unequal in length. 

 Prosternal process rather narrow between the coxal cavities, and 

 arcuately declivous posteriorly. Anterior coxae moderately large, 

 globose, not angulated externally, and the cavities closed posteriorly. 

 Intermediate coxal cavities closed externally. Legs unequal in 

 length ; tibiae not longitudinally carinate ; femora petiolate at bases, 

 strongly clavate and unarmed at apices ; posterior tarsus broad, with 

 the first joint scarcely longer than the second. Body vaguely 

 pubescent. 



Genotype. — Lamproclytus elegcms, new species. 



This genus belongs to the tribe Tillomorphini and is allied to TiUo- 

 niarpha Blanchard, but it differs from that genus in having the an- 

 tenna 10-jointed, distinctly shorter than the body, gradually expanded 

 toAvard the tip, and the first joint short, palpi very short and sub- 

 equal in length, elytra with eburneous fasciae, and the first joint of 

 the posterior tarsus distinctly longer than the second joint. 



LAMPROCLYTUS ELEGANS, new species 



Feinale. — Elongate, nearly parallel, moderately convex above, 

 strongly shining, black, except basal third of each el3i;ron, basal 

 joint of antenna, mesosternum, metasternum, and basal halves of 

 femora, which are brownish yellow, and each elytron ornamented 

 with a transverse, eburneous fascia. 



Head with the front strongly transverse, even, flat between the an- 

 tennal tubercles, which are small, very widely separated, and scarcely 

 elevated, coarsely alveolate-punctate, sparsely clothed with moder- 

 ately long, semierect, white hairs ; eyes separated from each other on 

 the top by four times the width of the upper lobe. Antenna extend- 

 ing just beyond base of elytron, basal joints cylindrical, feebly ex- 

 panded toward tips, clothed with a few long, erect, white hairs, 

 apical joints broader, slightly flattened, rather densely clothed with 

 short, recumbent pubescence, with a few long, erect hairs intermixed ; 

 first joint robust, cylindrical, two and one-half times as long as the 

 second joint, which is two-thirds as long as the third; joints 4 and 

 5 twice as long as the second; joints 6 and 7 subequal in length to 

 the third joint, and subtriangular ; joints 8 and 9 subequal in length 

 to the second joint, and as wide as long; tenth joint oval, subequal in 

 length to the third, and acute at apex. 



Pronotum distinctly longer than wide, slightly wider at apex than 

 at base, and widest at middle; sides strongly, arcuately rounded 

 from apex to basal sixth, where they are strongly constricted, then 

 parallel to the base; disk even, strongly convex, broadly, feebly, trans- 

 versely depressed along apex, and strongly, transversely constricted
