114. MELANOPLUS CONFUSUS, new species. 

 (Plate XXII, fig. 10.) 



Of medium size, flavo- testaceous. Head not prominent, probably 

 tiavo-luteous in life, marked with fuscous above in a median stripe and a 

 pairof divergent, posteriorly enlarging stripes, besides a broad, distinct, 

 piceous, postocular band; vertex somewhat tumid, slightly elevated 

 above the pronotum, the interspace between the eyes hardly so wide 

 as 1 (male) or almosfrtwice as wide as (female) the first antennal joint; 

 fastigium gently declivent, deeply (male) or shallowly (female) sulcate; 

 frontal costa subequal, but slightly broader below, about as broad as 

 the interspace between the eyes, distinctly sulcate at and below the 

 ocellus, biseriately punctate above; eyes of moderate size and promi- 

 nence, only slightly more prominent in the male than in the female, a 

 little longer than the infraocular portion of the genae; antennae luteous, 

 slightly infuscated next the apex, about two-thirds (male) or but little 

 more than a half (female) as long as the hind femora. Pronotum with 

 the prozona subequal except for the tumid sides, the raetazoua expand- 

 ing considerably, the sides of the prozona with a broad, piceous, 

 postocular baud, which is sometimes a little maculate or strigose with 

 luteous, the disk broadly convex and passing by a well-rounded shoul- 

 der, forming blunt lateral carinae on the inetazona and extreme front of 

 prozona, into the vertical lateral lobes; median carina distinct, sub- 

 equal, percurrent; front margin truncate, with feeblest sign of minute 

 emargination, hind margin obtusangulate; prozona distinctly longi- 

 tudinal (male) or longitudinally subquadrate (female), very sparsely 

 punctate, not a great deal longer than the finely and densely punctate 

 inetazona. Prosternal spine moderately long, compressed, blunt coni- 

 cal, feebly retrorse (male), or rather short, appressed conical, very 

 blunt, erect (female): interspace between mesosternal lobes about half 

 as long again as broad (male) or quadrate (female), the metasternal 

 lobes approximate (male) or moderately distant (female). Tegmina 

 long and rather slender, subequal, slightly or considerably surpassing 



'Undoubtedly wider in life, the exceptionally deep sulcation of the fastigium of 

 the single male indicating a contraction of the intraocular space from drying after 

 immersion in alcohol.
