< renus Alota 3 gen. nov. 



The insect upon which the present genus is based comes from 

 Bolivia. lis general aspeel is that of an Orphulella. On closer 

 inspection, however, it proves to be very different. In fact it is found 

 to belong close to the Scyllincz. Its chief characteristics are a medium 

 sized head with prominent eyes, a slightly depressed, somewhat 

 acuminate vertex, which is deeply sulcate, and provided in front with 

 well-defined, visible foveohe, which are much longer than wide; the 

 front, pronotum, and pleura are very coarsely and deeply punctulate; 

 the pronotum is sub-sellate and without lateral carina?; the tegmina 

 lire long and narrow, profusely veined at the base and along the dorsal 

 field, without an intercalary vein, and rounded at apex; the wings 

 lack the fenestrate character of Orphulella and allies; the hind femora 

 are wide and robust on the basal half, but slender beyond, with regular 

 pinnae externally, the genicular lobes rounded at apex; tibiae adorned 

 with comparatively few, but large, spines; the mesosternal space or 

 interval is unusually wide. 



A more complete diagnosis follows in connection with the specific 

 description given below. 



41 ). Alota boliviana sp. nov. 



Size below the medium, slender, with narrow tegmina and wings, 

 which pass both the abdomen and femora, the apex of former rounded. 

 Front, pronotum, and pleura strongly punctulate. General color dull 

 wood-brown, paler below". Hind tibia 1 pale glaucous. 



Head small, scarcely as wide as the front end of the pronotum, the 

 front strongly oblique. Eyes prominent, rounded behind, more nearly 

 straight in front, their longest diameter almost a third greater than 

 the anterior margin of the cheeks, separated above by a space nearly 

 or quite one and one-half times the width of the frontal co&ta between 

 the antennas; fastigium of the vertex a little longer than broad, 

 triangular, quite deeply sulcate, the antero-lateral carime prominent 

 and meeting in a slightly acute angle; lateral foveohe visible from 

 above, about twice as long as wide. Frontal costa fairly prominent, 

 a little narrowed next to the fastigium, wider between the antennae, 

 narrowed a trifle in the vicinity of the ocellus and divergent below 

 and continued to the clypeus, somewhat sulcate, punctulate above and 

 below. Lateral or facial carinae prominent, continuous from the ocelli
