and feebly compressed basally, scarcely incurved ; infracercal plate as 

 long as the supraanal by the apical prolongation of the narrowing plate. 



Length of body, male, L7 mm.; antennae, 6 mm.; tegmina, 15 mm.; 

 hind femora, 9.25 mm. 



One male. Mohave, Arizona, Wickham (L. Bruner). 



In details of structure this species closely resembles Ae. arizonensis, 

 but is remarkable for its compressed form and its large and prominent 

 eyes, in which points it exceeds even that species.

 Bradynotes SCUDDER, Can. Ent., XII (1880), p. 76. 



Body stout, compact, heavy, generally, and especially in the female, 

 very broad at the metathorax. Head stout, slightly broader below 

 than above, the genae full ; eyes separated by a wide space, wider and 

 generally much wider than the broad frontal costa; front well rounded, 

 vertical, the frontal costa prominent, broad, and generally somewhat 

 sulcate, at least above; antennae slender for such bulky insects, equal, 

 shorter and generally much shorter than the hind femora. Thorax very 

 stout, the pronoturn very short, not covering the whole of the meso- 

 notum, truncate at either extremity, the metazona only about half as 

 long as the prozona and rugulose, while theprozona is smooth; lateral 

 lobes sometimes separated from the dorsum by distinct rugae. Pro- 

 sternal spine very much abbreviated, becoming in the female a mere 

 blunt tubercle, and in the male very short and conical; mesostethium 

 and metastethium together, in both sexes, but particularly in the female, 

 no longer or scarcely longer than broad; the interspace between the 

 mesosternal lobes wide in both sexes, but showing a remarkable degree 

 of variation quite unknown in any other of the genera of Melanopli; 

 the metasternal lobes distant, sometimes very distant, in the female, 

 approximate or moderately distant in the male. Tegmiua and wings 

 altogether wanting. Fore and middle femora of male tumid; hind 

 femora (excepting in B. hispida) rather short, moderately stout, reach- 

 ing beyond the abdomen in the male, but generally not in the female, 

 the upper carina smooth. Terminal abdominal joints of the female 

 short, with slightly exserted ovipositor, making the tip blunt, as in 

 Oedaleonotus and Aeoloplus, but perhaps to a greater degree; abdo- 

 men of male apically clavate, upturned, the subgenital plate long and 

 tumid, without apical tubercle; furcula absent or (in one species) rep- 

 resented by feeble lobes: cerci simple, conical, straight. 



B. obesa (Thomas) is the type. 



This somewhat remarkable genus is, so far as known, confined to the 

 extreme northwestern United States, but will probably be found also 

 in British Columbia. It extends from the Pacific to Montana and 

 Wyoming, and has so far been reported only north of the latitude of
