fine erect and conspicuous on the elytra. Head as long as wide, semicircular 

 behind, the eyes rather small but convex and prominent, situated just before 

 the middle; antennal prominences moderate, the front distinctly impressed 

 between them ; clypeus long and well developed, the apex transversely recti- 

 linear, with the feeblest trace of a broadly rounded inequality at the middle but 

 not toothed; maxillary palpi long and slender. Antennse slender, fully 3^ as 

 long as the body, the club slender and very gradual in formation; second joint 

 obconic, scarcely % longer than wide, not quite as long as the next two and 

 but slightly thicker; three to six equal in width, feebly obconic, the sixth 

 cylindric; third not quite as long as wide; fourth scarcely longer; fifth nearly 

 3^ longer than wide; sixth rather longer than wide; seventh }4 wider, parallel 

 with the sides broadly arcuate, at least }^ longer than wide; eighth scarcely 

 y^ thicker, oval, a little longer than wide; ninth just visibly thicker than the 

 eighth, rather longer than wide; tenth still very slightly wider, as long as 

 wide; eleventh rather thicker, obliquely pointed, not quite as long as the two 

 preceding. Frothorax conic as usual, not quite as long as wide, with the apex 

 rather more than J-^ as wide as the base, which is about 34 wider than the 

 head; surface transversely impressed near the base, the impression not dis- 

 tinctly interrupted at the middle. Elytra large and ample, fully 3^ longer 

 than wide, nearly 2^^ times as long as the prothorax and fully ^5 wider, widest 

 before the middle, narrow and subacute at apex, the sides evenly rounded; 

 humeral plica rather long and strong, the impression large; foveas deep; sub- 

 sutural impressions narrow, very deep and conspicuous, the suture strongly 

 beaded basally, the bead gradually increasing in width. Abdomen with the 

 basal segment overlapping the next, unevenly fringed at apex. Legs rather 

 long; femora moderately clavate, the anterior strongly so. Length 1.75 mm. ; 

 width 0.8 mm. 



Texas (Colorado River). 



Very closely allied to capillosulum, but slightly larger and 

 with a still more slender and gradual antennal club, less inter- 

 rupted transverse impression of the pronotum, larger head, 

 stronger subsutural impressions, shorter tibial spur of the male 

 and longer hind tarsi. The tibial spur of the male is straight, 

 oblique, simple and very slender, and is distinctly less than half 

 as long as the tarsus. A single specimen. 



69. C illustre n. sp. — Eather stout, suboval, highly polished and im- 

 punctate, piceous-black, the elytra bright red, rather dusky at base and on the 

 flanks ; legs and antennae pale reddish-brown ; pubescence abundant, long 

 erect pale and conspicuous on the elytra. Sead very nearly as long as wide,^ 

 semiciicular behind, the eyes only moderately large but very convex and 

 prominent, near the middle ; antennal prominences feeble, the front slightly 

 impressed ; clypeus long and well developed, highly polished and impunctate, 

 the apical edge perfectly even and without trace of median modification. 

 Antennse more than % ^s long as the body, the club gradual and elongate but 

 quite heavy ; second joint feebly obconic, }4, longer than wide, not quite as
