REVTSTON OF EI.EODTTNT BLAISDELL. 491 



Elytra oval, about a third longer than wide, widest at the middle; 

 Ixtse not margined nor adapted to the contiguous prothoracic base, 

 not narrower; humeri roundeil or feebly subangulate at the meeting 

 of the humeral and subhumeral costse; sides evenly and moderately 

 arcuate, apex not noticeably produced when viewed from above, 

 rather broadly rounded; dhc rather strongly convex from side to 

 side, slightly depressed on the dorsum, arcuately declivous poste- 

 riorly, but sinuate before the slightly oblique apex ; surface sculptured 

 witli a sutural and four costa? on each side, each acutely elevated, 

 sutural costa feeble and evidently distinct to the apex, subhumeral, 

 humeral and outer discal costie unite on each elytron near apex in 

 a distinct tubercle, the internal discal costa becoming evanescent on 

 the declivity; each costa is distinctly subserrulate on crest from a 

 series of impressed and A'f^ther distantly spaced punctures, each 

 puncture with a minute seta; intervals broad and apparently biseri- 

 ately subfoveolate, the foveola^ rather distinctly marked and more 

 or less transversely coalescent, giving a subreticulate appearance; 

 each interval with sparsely placed minute elevated granules, which 

 bear a minute seta projecting from their base behind; sculj)turing 

 irregular in the outer intervals. 



Epipleurai narrow and entirely overlapped by the sternal side 

 pieces and first three abdominal segments, exposed apical portion 

 horizontal, also briefly exposed beneath the humeri. 



Sterna and j^arajdcvrn' more or less scabrous and somewhat tuber- 

 culate. Sterna feebly concave. 



Abdomen horizontal, moderately convex, first segment distinctly 

 flattened and sligiitly concave between the coxa^, second segment 

 very feebly flattened at middle thii'd; surface more or less scabro- 

 tuberculate. 



Le(/f< short and scabrous. Femora tuberculately punctate, with a 

 minute tooth at outer fourth on the ])rofemora. Tibia^ muricato- 

 tuberculate, i)rotibia' somewhat constricted at base. Tarsi short and 

 feel)ly grooved, first joint of the protarsi moderately produced at tip 

 beneath. 



Measurements. — Male: Unknown. Female: Length, 12 mm.; 

 width, G mm. 



Genital eharacters., male. — Not studied. 



Female. — Genital segment (Plate G, fig. 14) triangular, a little 

 longer than wide, fully chitinized, valves slightly reflexed. 



Valvula. — Dorsal plate ehmgate, oblong-triangular; surface gla- 

 brous and slightly longitudinally concave, very sparsely punctate and 

 setose apically, setse short; external border more or less feebly sinu- 

 ate, somewhat prominent toward base; internal margin straight. 

 Apex not defined from the dorsal plate, briefly sinuate externally, 

 forming a fossa, tip rounded, but not broadly so; internally finely 

 setose on the valvular membrane.
