General coloration buffy, the tegmina distad pale green ; probably 

 uniform pale green in life. Eyes dark brown. Antennae immac- 

 ulate. Pronotum with a band of ochraceous-orange defining on 

 each side the lateral margins of the disk, this continued as a pos- 

 tocular band on the head. 



Length of body 11.2, length of pronotum 4.8, greatest total 

 width of pronotum 2.8, length of lateral lobe of pronotum 2.3, 

 depth of lateral lobe of pronotum 2.1, length of tegmen 16.9, 

 width of tegmen 2.8, length of cephalic femur 3.6, length of caudal 

 femur 10.7 mm. 



The unique male is before us.

The previously unknown male of this species is briefly compared 

 with that of A. bakeri under that species. 



In the present pair the ventro-cephalic angle of the lateral lobes 

 is very weakly indicated in the male, obsolete in the female. The 

 male genitalia show the highest specialization known for the species 

 of Alloteratura. Cerci heavy and irregular in contour, stout in 

 proximal third to a dorso-internal node, median third tapering in 

 vertical section with dorso-external margin sharply angulate, distal 

 third with margins curving weakly to the apex and dorsal margin 

 sharp; the cerci curve inward and upward with some angulation 

 indicated at each section described above and embrace the large 

 yoked portion of the ultimate tergite. This projects mesad above 

 the cerci as a large, vertical, transverse, rounded lobe and is pro- 

 duced ventrad beyond the cerci and apex of the subgenital plate 

 as a stout cone, with apical portion lamellate, truncate and directed 

 ventrad. Subgenital plate with lateral margins weakly convex 

 convergent, a longitudinal carina on each side terminating at the 

 latero-caudal angle and there supplied with a slightly decurved 

 style, three times as long as its basal width; between the cerci the 

 plate is bilobate, these small projections forming a broad V-shaped 

 emargination mesad.
