edge roundly narrowing, so that at the end of the parallel portion 

 they are graceful and nearly equal, and from this point are directed

 spine robust, subquadrate, short, the apex somewhat acuminate.

Habitat. — A single male taken by R. J. Crew at the same locality 

 as the preceding species. (Coll. L. Bruner.) 



1 01. Caloscirtus rubripennis gen. nov. et sp. nov. 



A rather small, fairly robust, olive-green locust, with bright blood- 

 red hind-wings, red dorsum of abdomen, and elongate, slender, red 

 antenna'; and in which the hind femora are decidedly robust and pro- 

 vided with tuberculate or semiserrate upper carina?. 



Head slightly wider than the front edge of the pronotum, the 

 occiput short, eyes large and moderately prominent, nearly one- third 

 longer than that portion of the cheeks below them, vertex narrow, 

 less than half as broad as the frontal costa, between the base of antenna? ; 

 fastigium somewhat depressed, sulcate, and separated from the frontal 

 costa by a rather prominent transverse carina; frontal costa a little 

 prominent between the antenna?, shallowly sulcate, and provided in 

 the middle with a broad longitudinal carina, broadest above, but 

 narrowing towards the ocellus, below which point it is obsolete. Face 

 rugose and coarsely punctate, the lateral carina? inconspicuous and 

 slightly bowed outward at their middle, but little further apart at their 

 lower than upper end; cheeks also coarsely punctate, likewise the 

 occiput in part. Antenna? twenty-two-jointed, slender, nearly as long 

 as the hind femora (cf ) the basal joint large, about as broad as the 

 greatest width of the frontal costa. Pronotum coarsely rugoso- 

 pu net ate, a trifle expanded on the hind lobe; median carina distinct, 

 interrupted by the well-marked transverse sulci; anterior margin 

 roundly advanced upon the occiput in middle, obtusangulate behind. 

 Pleura coarsely punctate. Tegmina rather narrow, sparsely, but 

 strongly, veined, as long as the abdomen ; wings a little shorter than 

 the tegmina, obtuse, and with the outer margin strongly undulate. 

 Hind femora robust and provided with coarse, large knees, their upper 

 edges sub-serrate on carina? and coarsely punctate, the pagina? to- 

 gether with the lower carina? and face smooth, genicular lobes sub-
