NO. 1 124. RE VISION OF THE MELANOPLI SC UDDEE. 211 



_: 



40. MELANOPLUS INDIGENS, new species. 

 (Plate XIV, fig. 4.) 



Of medium size, brownish fuscous above, sordid testaceous beneath. 

 Head a little prominent, olivaceo-testaceous necked with fuscous, above 

 blackish fuscous with a broad piceous post ocular baud; vertex some- 

 what tumid, scarcely elevated above the pronotum, the interspace 

 between the eyes half as broad again as the first antennal joint; fas- 

 tigium steeply declivent, shallowly and broadly sulcate; frontal costa 

 scarcely reaching the clypeus, faintly expanded at the ocellus, but 

 otherwise equal, a little narrower than the interspace between the eyes, 

 a little sulcate below the ocellus, distinctly punctate above; eyes rather 

 large, not prominent, somewhat longer than the intraocular portion of 

 the genae; antennae castaneous, almost as long as the hind femora. 

 Prouotum slightly expanding on the metazoua, the sides with a per- 

 current, piceous, postocular stripe which is rather feeble on the nieta- 

 zona, the disk rather broadly convex, passing by a rounded shoulder, 

 posteriorly forming feeble lateral carinae, into the somewhat tumid 

 vertical lateral lobes; median carina distinct on the metazona, obsoles- 

 cent on the prozona; front margin subtruncate, hind margin very 

 broadly rotundate ; prozona distinctly longitudinal, about a third longer 

 than the finely punctate metazona. Prosternal spine long, conical, 

 bluntly pointed, feebly appressed; interspace between mesosternal 

 lobes subqnadrate, barely longer than broad. Teginina abbreviate, 

 almost as long as the pronotum, slightly distant, obovate, almost twice 

 as long as broad, the tip strongly rounded. Fore and middle femora 

 somewhat tumid in the male; hind femora rather slender, somewhat 

 compressed, ferrugineo-testaceous, irregularly clouded and necked with 

 fuscous, the under face flavo-olivaceous, the upper genicular lobe and 

 base of lower black; hind tibiae sordid pale greenish with a fuscous 

 patellar anuulus, the spines black almost to their base, ten to twelve 

 in number in the outer series. Extremity of male abdomen hardly 

 clavate, somewhat recurved, the supraanal plate triangular with acut- 

 angulate apex, the lateral margins considerably and rather abruptly 

 elevated and mesially notched, the median sulcus distinct and percur- 

 rent between rather narrow and sharp ridges which fade beyond the 

 middle; furcula consisting of a pair of rather slender, tapering and 

 acuminate, tumid, feebly arcuate and slightly divergent fingers, 

 slightly longer than the last dorsal segment; cerci broad and rather 

 coarse, straight, subequal, apically rounded or subangulate laminae, 

 nearly four times as long as their middle breadth, obliquely vertical 

 throughout except apically, where by a feeble twist they become verti- 

 cal; subgenital plate short and broad, the apical margin rising consid- 

 erably above the lateral into a slight rounded tubercle, the lateral and 

 apical margins as seen from above parabolic. 



Length of body, male, 20 mm.; antennae, 10 mm.; teginiua, 4.25 

 mm ; hind femora, 11 mm.
