96. Stenacris megacephala sp. nov. 



This insect is characterized chiefly by its excessively large and 

 smooth head, which is considerably wider than the anterior edge of 

 the strangulate pronotum, which is likewise rather robust; also by 

 the widely lamellate lateral edges of the hind tibiae. 



Fastigium of the vertex depressed, somewhat declivant in front, 

 the base almost twice as wide as the median length, separated from 

 the vertex by a rather well-defined transverse furrow, the disc full 

 and showing only slight indication of a longitudinal sulcus or irre- 

 gularities, the sides nearly straight, the anterior angle obtuse. Vertex 

 between the eyes fully twice the width of the basal antennal joint. 

 Front somewhat oblique, but not so greatly as in the other species, 

 of the genus. The frontal costa rather broad and roundly sulcate, 

 viewed laterally straight, its lateral walls not greatly sinuose, con- 

 tinuous to the base of the clypeus. Antennae sublinear, scarcely at 

 all enlarged at their base, of normal length, not reaching much beyond 

 the last transverse sulcus of the pronotum. The latter faintly and 

 minutely punctulate, smooth, narrowest at the hind sulcus, which is 

 narrow, but profound, the other sulci also deeply but narrowly im- 

 pressed. Tegmina somewhat acuminate, extending but little beyond 

 the tip of the abdomen. Valves of the ovipositor rather short, the 

 teeth email and weak, the apex of the lower pair scarcely hooked. 

 Prosternal spine moderately large, long and club-shaped, directed 

 somewhat caudad, its apex blunt and almost touching the anterior 

 margin of the mesosternum. 



General color' of front, head above, pronotum and tegmina oliva- 

 ceous, lower edges of the cheeks, sides of the pronotum and meso- 

 and metapleura rather widely streaked longitudinally with ivory- 

 white, this in turn bordered above by a fuscous or dull piceous band, 

 which gradually merges above into the general olive hue. Anterior 

 and middle legs greenish, fading basally to testaceous, the hind 

 femora olivaceous yellow, or greenish straw-color; hind tibiae oliva- 

 ceous basally, becoming pale vinaceous apically, the hind tarsi coral- 

 red. Antennae ferruginous, apically infuscated. 



Length of body, 9 , 36 mm.; of head in front of the pronotum 5.5
