RENOCIS FUSCUS, new species 



FiGiXRES 17, ;■; 18, g 



/^emaZe.— Piceous-brown, clothed with scales varying from ciner- 

 eous to fuscous; 1.88 mm. long, 1.9 times as long as wide. 



Frons with sharp median point on epistomal margin, with a dense 

 fringe of yellowish-cinereous setae; transversely impressed above the 

 epistoma, with impression widened dorsally to form a concavity; 

 sides and vertex convex; surface black, shining, finely and densely 

 punctate, with fine granules at sides and above ; surface partly con- 

 cealed by coarse, rather long, light-brown setae, more abundant and 

 longer at the sides and above. Eye more than 3 times as long as 

 wide, finely gi-anulate; inner margin feebly sinuate. Antenna with 

 club '(fig. 17, i) subacuminate at tip; 2.5 times as long as wide; with 

 3 straight, annulate-setigerous sutures. 



Pronotum 1.6 times as wide as long, widest one-third of distance 

 from base, which is feebly procurved; sides strongly arcuate behind, 

 strongly constricted before middle; front margin broadly rounded, 

 sinuate in middle; with a sparse fringe of erect, spatulate, fulvous 

 setae, shorter in middle, with a transverse impression just back of 

 anterior margin ; surface piceous, shining, rather closely, finely punc- 

 tate, finely granulate; at each side two groups (2 or 3 in each) 

 of very small asperities; surface nearly concealed by numerous, small, 

 recumbent scales, arranged as a broad band at the base and at sides, 

 made up largely of broad and narrow cinereous scales intermixed, 

 and on anterior two-thirds of disk small, broad, fulvous scales. 



Elytra 1.25 times as long as wide, wider than pronotum; sides 

 straight and subparallel on anterior two-thirds, broadly rounded be- 

 hind; basal margin strongly elevated from suture to sixth interspace, 

 with 'six or seven crenulations at each side, forming a continuous 

 line; striae moderately narrow, distinctly impressed, punctures fine 

 and 'close; interspaces broad, flat, surface shining, finely punctate, 

 with a median row of slightly coarser punctures, rather sparsely 

 clothed with numerous small, rather slender, recumbent, fuscous 

 scales; in the median line of each interspace a row of erect spatulate 

 setae, appearing cinereous in certain lights and fuscous brown m 

 other lights; each elytron with a group of coarse, erect, fuscous setae
