22. MELANOPLUS AFFINIS, new species. 

 (Plate XII, fig. 2.) 



Melanoplus affinis BRUNER!, MS. 



[Some of the synonymy given under M. atlanis almost certainly belongs here.] 



Slightly above the medium size, rather robust, griseo-fuscous, testa- 

 ceous beneath. Head olivaeeo-plumbeous, the elypeus and labrum 

 paler, above more or less rufous and marked with fuscous, with a 

 piceous postocular band; vertex gently tumid, slightly elevated above 

 the prouotum, the interspace between the eyes half as broad again 

 (male) or fully twice as broad (female) as the first antennal joint; fas- 

 tigium very steeply decliveut, broadly and considerably (male) or feebly 

 (female) sulcate; frontal costa reaching or almost reaching the elypeus, 

 as broad as the interspace between the eyes, feebly narrowed above at 

 least in the male, irregularly punctate throughout but more densely 

 above than below, feebly sulcate at and slightlybelow the ocellus; eyes 

 moderately large, not very prominent, much longer than the infraocular 

 portion of the genae; antennae flavo testaceous, about three-fourths 

 (male) or about two-thirds (female) as long as the hind femora. Prono- 

 tum subequal, expanding a little on the metazona, darker above than 

 on the sides, the lateral lobes of the prozona with a more or less dis- 

 tinct, sometimes broken, broad, piceous, postocular band, the disk nearly 

 plane but broadly convex, passing into the subvertical lateral lobes by 

 a well rounded but distinct shoulder, forming tolerably distinct lateral 

 carinae on the metazona j median carina percurrent, distinctly feebler 

 on the prozoua than on the metazona, as distinct between the sulci as 

 in advance of them ; front margin very feebly and very narrowly flaring, 

 truncate, hind margin obtusangulate, the angle not much rounded; 

 prozona feebly longitudinal or quadrate (male) or somewhat transverse 

 (female), scarcely if any longer (male) or faintly shorter (female) than 

 the densely but somewhat obscurely punctate metazona. Prosternal 

 spine moderately long, cylindrical, erect, very blunt and faintly appressed 

 in the male, similar but shorter and more conical in the female; inter- 

 space between mesosternal lobes twice or more than twice as long as 

 broad (male) or subquadrate (female). Tegmina surpassing considera- 

 bly the hind femora, moderately narrow, tapering feebly, rufo-fuscous 

 or griseo-fuscous, with a distinct but more or less pronounced median 

 series of fuscous annulations intercalated in basal half between more or 

 less pronounced pallid dashes or spots; wings hyaline, the veins heavily 

 i n fu seated apically and anteriorly. Fore and middle femora of male 

 moderately tumid ; hind femora rufo-testaceous, more or less clouded 

 with fuscous and feebly bifasciate with fuscous above, the lower face and 

 at least the lower half of the inner face roseate, the genicular arc black; 

 hind tibiae pale glaucous, flavescent at apex and with a fuscous patel- 

 lar spot, the spines black on more than the apical half, eleven, occasion- 

 ally twelve, in number in the outer series. Extremity of male abdomen
