femoral margins, piil villi, tarsal claws and arolia as characteristic 

 of the genus. 2 



Allotype: 9 ; same data as type. [Hebard Collection.] 

 Specimen much damaged. Agrees with type in ambisexual char- 

 acters, differing as follows. Form almost imperceptibly more slen- 

 der. Genitalia so damaged that the subgenital plate alone can be 

 seen to bear two simple styles, much of the type found in A. lateralis 

 Burmeister, the sinistral being the longer and heavier and directed 

 dextrad. 



Head chestnut brown. Pronotum with disk ochraceous-buff, 

 with a large suffusion of prouts brown in area above the head, lat- 

 eral portions translucent buffy. Tegmina translucent buckthorn 

 brown, except in narrow marginal field which is translucent buff. 

 Wings with appendicular field heavily tinged with mummy brown. 

 Cerci, underparts and limbs warm buff. Ventral surface of ab- 

 domen ochraceous-buff, suffused broadly but not heavily both lat- 

 erad and distad with prouts brown. 



Length of body cf 4, 9 4.1; length of pronotum cf 1.2, 9 1.2; 

 width of pronotum cf 1.7, 9 1.7; length of tegmen cf 3.6, 9 3.9; 

 width of tegmen cf 1.4, 9 1.4; length of appendicular field of wing

This strikingly colored species is known from the described pair.

This specimen, the first male of the present species to be studied, 

 is seen to have the supra-anal plate large, extending as far as the 

 subgenital plate, with lateral margins converging weakly, then more 

 strongly and curving into the truncate distal portion. The sub- 

 genital plate with distal margin between the styles transverse and 

 moderately hairy, the dextral margin simple, obhque, the sinistral 

 margin transverse to sinistral style, with surface of plate in that 

 section broadly channeled, this portion produced into the sinistral 

 style, which is straight, produced for a brief distance, the margin 

 at the inner margin of this style suddenly produced for a short dis- 

 tance, in consequence of which the sinistral style is deeply inset, its 

 projecting portion equal in size and extending caudad the same 

 distance as the well-socketed, simple dextral style.
