 moderately stout and compressed, dull testaceous, rather broadly 

 bifasciate, at least above, with blackish fuscous, the base and apex 

 also infuscated, the under surface a little warmer in tint; hind tibiae 

 very delicate pale green, the spines black from a little before their 

 middle, nine to twelve in nuniber in the outer series. Extremity of 

 male abdomen clavate, upturned, the supraanal plate tolerably thit, 

 triangular with straight sides, acutangulate apex, the median sulcus 

 percurrent, with low bounding ridges which die out apically; furcnla 

 consisting of a pair of divergent, flattened, tapering, acuminate lingers, 

 which hardly cross the basal third of the su[)raanal plate; cerci mod-

 than three times as long as broad, a very little c«)ntracted mesially, the 

 ajMcal portion with its well rounded tip more or less externally sulcate 

 and narrower than tlie basal portion, reaciiing nearly to the tip of tiie 

 supraanal plate; subgenital plate broa<l but not so broad as long, 

 apically a little elevated, the ajiical margin well rounded, a little 

 thickened and entire.

13. ItrSTICUS SERIES. 



This is a tolerably homogeneous group in which tiie prozona of the 

 male varies from (juadrate to distinctly longitudinal and in which the 

 mesosternal lobes of the same sex are se|)arated by an interspace 

 which is rarely a little transverse, usually (juadrate or subquadrate, 

 and rarely as much as nearly half as long again as broad. The hind 

 border of the pronotum is usually very obtusangulate, and the tegmina 

 always abbreviate, usually about as long as the pronotum. The 

 hind tibiae are usually red, rarely pale greenish, with usually ten to 

 eleven spines in the outer series, but sometimes nine or twelve, and in 

 one case only seven spines may be found in th*^ female. 



The male abdomen is usually more or less clavate and recurved, the 

 supraanal plate triangular, its median sulcus inclosed by high walls
