12 Memoirs on the Coleoptera 



Rhadine testacea n. sp. — Form very slender, feebly convex, pale 

 testaceous throughout and shining; head long, three-fourths as wide as 

 the prothorax, the eyes moderate, prominent, the tempora behind them 

 converging and nearly straight to the rather long neck, about half as 

 wide as the prothorax; antennae pale, fully half as long as the body, the 

 third joint a fourth longer than the fourth; front very smooth; prothorax 

 barely longer than wide, strongly inflated and rounded at the sides, which 

 become much constricted and sinuate at base, the angles acute and 

 slightly prominent; base feebly sinuate, much narrower than the rather 

 deeply sinuate apex; fovese not deep but extending about to the middle; 

 elytra very long, rather more than twice as long as wide, almost one-half 

 wider than the prothorax, the broadly arcuate sides more broadly and 

 strongly reflexed than usual, oblique and broadly sinuate at apex, the 

 apical angles slightly produced and angulate; surface of each broadly 

 concave basally, smooth, alm.ost as shining as the pronotum; striae 

 finely, irregularly subpunctate, not very fine but abrupt, the intervals 

 fiat; dorsal punctures small, five in number, adhering to the inner side 

 of the third stria; lateral foveoles numerous, forming an evenly spaced 

 series from base to apex. Length (9 ) ii-5 mm.; width 3.4 mm. Col- 

 orado (Cripple Creek), — Cockerell. 



This species may be placed next after constricta, having very 

 nearly the same form of prothorax, but it is smaller, much more 

 slender, paler in color, with flat and not broadly convex strial 

 intervals and more slender legs and antennae; in constricta the 

 dorsal junctures of the elytra are also four or five in number. 



Rhadine plumasensis n. sp. — Form very elongate, slender, distinctly 

 though moderately convex, shining, the elytra feebly alutaceous; color 

 dark rufous throughout, excepting the elytra, which are piceous; head 

 somewhat elongate, much narrower than the prothorax, the eyes moderate 

 in size and but slightly prominent; neck three-fifths the thoracic width; 

 front convex, smooth, the anterior impressions shallow, linear and oblique; 

 antennae not quite half as long as the body; prothorax distinctly elongate, 

 the sides broadly, subevenly rounded, feebly oblique but scarcely visibly 

 sinuate posteriorly, the basal angles distinctly more than right and with 

 their tips blunt; base broadly sinuate, evidently narrower than the sinu- 

 ate apex; anterior impression obsolete, the posterior feeble, transverse, 

 the stria deeply impressed, not extending behind the posterior im- 

 pression; sides narrowly reflexed, broadly so at the hind angles; foveae 

 rather indefinitely limited; elytra long, fully twice as long as wide, not 

 quite one-half wider than the prothorax, the sides evenly arcuate, 

 strongly but not widely reflexed, oblique and feebly sinuate at apex, 

 the sutural angles briefly produced and sharply angulate; striae rather 

 fine, sharp, not punctulate, the intervals flat; dorsal punctures minute, 

 three or four in number, situated on the third stria; lateral series of 

 foveoles nearly as in the preceding; scutellar stria long but subobliterated; 

 anterior tarsi of the male stout, convex and not grooved above. Length 

 (cf) 13.0 mm.; width 4.0. mm. California (Plumas Co.).
