NO. 1124. REVISION OF THE MELANOPLISCVDDER. 323 



rounded in the female and sometimes in the male; prozona distinctly 

 longitudinal (male) or quadrate or feebly longitudinal (female), generally 

 more (male) or generally less (female) than one-third longer than the 

 closely punctate metazona. Prosternal spine long, appressed cylin- 

 drical, blunt, retrorse; interspace bet ween mesosternal lobes about half 

 as long again as broad (male), or feebly transverse (female). Tegmina 

 abbreviate, a little longer than the pronotum, overlapping, very broad 

 just beyond the base and rapidly narrowing, short sublanceolate, the 

 costal margin roundly angulate, apically subacuminate, the dorsal and 

 lateral fields angularly separated, brownish fuscous, the dorsal field 

 often cinereous, the lateral often feebly flecked with fuscous. Fore and 

 middle femora very tumid in the male; hind femora testaceous or flavo- 

 testaceous r heavily and broadly but sometimes confusedly bifasciate 

 with blackish fuscous, the geuiculation blackish, the inferior face pale 

 flavous, pallid apically; hind tibiae red, blackish at the base, fol- 

 lowed by an obscure pallid annulus, below which the red is feebly 

 infuscated, the spines black on their apical half, ten to eleven, rarely 

 nine, in number in the outer series. Extremity of male abdomen 

 strongly clavate, much recurved, the supraanal plate triangular, with 

 an acutangulate or rectangulate apex, slightly angulate sides which are 

 considerably and gradually elevated, and a tolerably broad, percurrent, 

 moderately deep but apically fading median sulcus, broadened at 

 extreme base, lying between sharp walls; furcula consisting of a pair 

 of approximate denticulations of varying length, but generally at least 

 as long as the last dorsal segment, generally slenderer than represented 

 in the figure; cerci coarse and heavy, broad at base, rapidly narrowing, 

 so that the middle is about two-thirds as broad as the extreme base, 

 beyond enlarging slightly, curved rather abruptly inward, and strongly 

 and abruptly compressed or exteriorly sulcate, the apex rounded sub- 

 truncate; subgenital plate rather broad and full, the lateral margins 

 arcuate, the apical margin gently elevated but not tuberculate, entire, 

 both margins together as seen from above subsemieircular. 



Length of body, male, 23 mm., female, 24 mm. ; antennae, male, 14 mm., 

 female. 10 mm.; tegmina, male, 9.5 mm., female, 8.5 mm.; hind femora, 

 male, 15 mm., female, 13.5 mm.
