NO. 1124. REVISION OF THE MELANOPLISCUDDEK. 195 



feebler on the prozoua than on the inetazona and more or less obsolete 

 between the snlci, the disk passing into the lateral lobes by a well- 

 rounded angle, becoming a tolerably distinct lateral carina on the 

 metazoua, the front margin subtruncate, the hind margin obtusangu- 

 late; prozona quadrate (male) or slightly transverse (female), scarcely 

 if any longer than the finely punctate metazoua. Prosternal spine 

 short, erect, conico cylindrical, feebly (male) or considerably (female) 

 appressed, blunt; interspace between mesosternal lobes somewhat less 

 than twice as long as broad (male) or feebly transverse (female). 

 Tegmina dark brownish fuscous, almost equally opaque throughout, 

 with distinct maculation in the discoidal field, reaching (male) or fall- 

 ing somewhat short of (female) the tips of the hind femora, not very 

 slender, distinctly tapering, well rounded apically. Hind femora fusco- 

 testaceous, rather obscurely and broadly fasciate with blackish fuscous, 

 the inferior face ferruginous; hind tibiae obscure pale green, with an 

 obscure fuscous basal annulus and often more or less flecked with fus- 

 cous, the spines black or brown with pallid base, ten to eleven in num- 

 ber in the outer series. Extremity of male abdomen clavate, somewhat 

 upturned, the supraanal plate somewhat long triangular, with slightly 

 convex and gently elevated lateral margins, a slightly produced 

 acutangulate apex (its production not shown in the figure), a rather 

 slender, not very deep, percurrent, median sulcus, with sharp but not 

 high walls, and a pair of parallel, slight, short, apical ridges; furcula 

 consisting of a pair of subparallel, flattened, tapering, acuminate fin 

 gers reaching nearly to the middle of the supraanal plate; cerci small 

 and slender, subequal but mesially contracted laminae, nearly four 

 times as long as broad, very faintly upcurved, apically a trifle incurved 

 and well rounded, the external face distinctly punctate and apically 

 feebly dimpled, with a very slight inward directed flange from the 

 lower margin apically, the whole falling far short of the tip of the 

 supraanal plate; infracercal plates rather broad and sulcate, but con- 

 cealed by the recumbent cerci except apically, as they are a little larger 

 than the supraanal plate; subgenital plate small, longer than broad, 

 the apical margin transverse, somewhat elevated but not prolonged, 

 thickened and distinctly notched. 



Length of body, male, 18.75 mm., female, 19.5 mm.; antennae, male, 

 7 mm; tegmiua, male, 14.5 mm., female 13 mm. ; hind femora, male, 10.5 

 mm., female, 12 mm. 



Two males, 3 females. San Francisco, California, October, November 

 (L. Bruner; S. H. Scudder). 



This species is very closely related to the last, and with larger 

 material may prove to be the same: but the anal cerci are faintly larger 

 apically than mesially in the present form, while in M. sierranus they 

 retain apically their mesial narrowness.
