no. 1124. EEFISIOX OF THE MELAXOPLI—SCCDltER. 1«J5 



feebler on the prozona than on the metazoua ami more or less obsolete 

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

 rounded angle, becoming a tolerably distinct lateral carina on the 

 nietazona, the front margin subtruncatc. the hind margin obtusangu- 

 late; prozona (juadrate (male) or sliglitly transverse (female), scarcely 

 if any longer than the finely punctate nu'tazona. Trosternal spine 

 short, erect, conico cylindrical, feebly (male) or ccmsiderablj^ (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 opa(|ue 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 tiecked with fus- 

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

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

 upturned, the supraanal plate somewhat long triangular, with slightly 

 convex and geiitl}' elevated lateral margins, a slightly pr<'dace<l 

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

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

 high walls, &,nd a pair of i)arallel, slight, short, apical ridges: furcula 

 consisting of a p-iir of subparallel, fiattened, 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, a')ically a trifie incurved 

 and well rounded, the external face distinctly punctate and apically 

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

 lower margin ajtically, 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 i)rolouged, 

 thickened and distinctly notched. 



Length of body, male, 18.75 mm., female, VJ.o mm.; antennae, male, 

 T mm; tegmina, 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. n. 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.
