<?2. Smaller forms, the males not reaching the length of 18 mm.; 



antennse of male almost as long as the hind femora; furcula absent; 



hind femora of both sexes glaucous, very rarely r&d.debilis sp. nov. 



A Tegmina longer than the pronotum, subacuminate at tip; cerci of 



male symetrically rounded at apex, above and below. 



(^/i. Interspace between mesosternal lobes of male hardly more than 

 half as long again as broad; extremity of subgenital plate elevated, 

 but not noticeably recurved blatchleyi Scudd. 



cP. Interspace between mesosternal lobes of male nearly or quite 

 twice as long as broad; extremity of subgenital plate elevated and 

 considerably recurved texanus Scudd.

Slightly below the medium size, dark fuscous or fusco- testaceous, 

 flavous beneath. Head faintly prominent, plumbeo testaceous, more 

 or less, sometimes heavily, flecked with fuscous, above almost wholly 

 fuscous, sometimes with a slender edging of testaceous to the postoc- 

 ular piceous band; vertex gently convex, a little elevated above the 

 pronotum, the interspace between the eyes a little wider than the first 

 antennal joint : fastigium steeply declivent, moderately sulcate ; frontal 

 costa percurrent, equal, fully as broad as the interspace between the 

 eyes, a little sulcate below the ocellus, biseriately punctate above ; eyes 

 moderately large, a little prominent, very much longer than the infra- 

 ocular portion of the genai ; antennae castaneous, pallescent at extreme 

 base, almost as long as the hind femora. Pronotum subequal, very 

 feebly expanding on the metazona, fuscous, with a broad piceous or 

 fusco-piceous postocular band on the prozona, beneath which the lat- 

 eral lobe? are plumbeo testaceous, the disk gently convex, passing by 

 a very rounded shoulder in no way simulating lateral carinse into the 

 vertical lateral lobes, which on the i)rozona are faintly tumid ; median 

 carina distinct but slight on the metazona, feeble on the prozona, sub- 

 obsolete between the sulci ; front margin truncate, hind margin gently 

 convex ; prozona a little longitudinal, about a quarter longer than the 

 rather obscurely punctate metazona. Prosternal spine moderate, erect, 

 feebly conical, blunt ; interspace between mesosternal lobes from half 

 as long again as broad to twice as long as broad, the metasternal lobes 

 attingent. Tegmina almost as long as the pronotum, attingent, obo-
