 vertical lateral lobes, often with feeble subtlavous lateral stripes next 

 the lateral (^arinae, the upper half of the lateral lobes of the prozona 

 occupied by a more or less distiiutt blackish (sometimes piceous) belt, 

 Sometimes followed below by luteous tle(;ks; median carina percurrent 

 but less distiiu't on the prozona than on the metazona, generally sub-

 less rufous or ferruginous, the genicular arc piceous; hind tibiae glau- 

 cous, the spines i)allid at base, black a-pically, nine to twelve (usually 

 ten) in number in the outer series. Extremity of male abdomen 

 clavate but apically conical, much recurved, the supraanal i)late tri- 

 angular, with feebly convex sides, bluntly a<!utangulate a|)ex, and 

 surface nearly plane except for the rather high, percurrent but ai>ic-
