and more parallel, and the elytral stria? more finely punctured and 

 more feebly impressed. The males and females are of similar form 

 and nearly equal in size, and the wings consist of an exceedingly 

 slender elongate parallel fillet, rather membranous in texture, devoid 

 of distinct venation, more than four times as long as wide, about 

 one-fourth longer than the prothorax and nearly one-half as long as 

 the elytra, with a deep sinuation on the lower edge near the apex. 

 This singular form is constant in the only two specimens dissected. 

 It will be seen, therefore, that the wings are very different from 

 those of pulverulentus, but approach those of inqixisitus, from which 

 parallelus differs in its longer prothorax, finer punctures of the 

 elytral striae and decidedly greater convexity. 



29 It. inquisitus n. sp. — Oblong-oval, moderately convex, strongly 

 shining, black above and beneath ; legs dark piceo-rnfous ; pubescence fine, 

 short, very sparse, dark piceo-cinereous and inconspicuous. Head moderate, 

 fully one-half wider than long, feebly convex, deeply, not very coarsely, 

 densely punctate, the punctures decidedly sparser along the middle ; epistoma 

 moderately sinuate ; upper lobe of eyes small, rounded; antennae somewhat 

 robust, the last three joints rather abruptly but slightly wider, third joint 

 twice as long as the second, the latter shorter than the fifth, three to five 

 uniformly and rapidly decreasing in length, eighth a little wider, as long as 

 wide, eleventh very slightly narrower than the tenth. Prothorax onedialf 

 wider than long, sides very feebly convergent from base to apex, evenly and 

 rather feebly arcuate ; base transverse, the sinuations moderately distinct ; 

 basal angles right, not at all rounded ; apex broadly, feebly emarginate in 

 circular arc ; disk somewhat finely, densely punctate, more sparsely so toward 

 the middle where the punctures are generally separated by one-half more than 

 their own diameters, not coalescent laterally. Scutellum moderate, densely, 

 finely punctate, the posterior edge broadly polished and impunctate. Elytra 

 subequal in width to the prothorax and about two and one-half times as long ; 

 sides very feebly arcuate, parabolically rounded at apex ; disk distinctly flat- 

 tened toward the suture, finely striate, the stria? feebly but rather abruptly 

 impressed, very slightly deeper and more coarsely punctate laterally ; strial 

 punctures generally fine and very approximate, usually separated by between 

 once and twice their own diameters ; intervals fiat, finely and sparsely punc- 

 tured. Abdomen polished, finely, sparsely punctate, the pubescence very sparse, 

 rather short, fine, dark fulvo-cinereous and not conspicuous. Legs moderately 

 robust. 



Male. — Anterior tarsi very strongly dilated, the second joint decidedly 

 longer than the third ; intermediate distinctly but not strongly dilated, the 

 second joint a little wider than the first and third ; abdomen narrowly and 

 rather strongly impressed in the middle toward base, the punctuation not 

 distinctly denser in the middle of the first segment. 



Length 5.0 mm. ; width 2.0 mm.
