with material of the g'cnotype, L. dccipiens (Germar ), in tlie Phila- 

 delphia Academy collection, shows full agreement in the following 

 characters, which we helieve define the genus. 



Tegmina greatly reduced, to a similar degree in the sexes. Ventro- 

 cephalic margin of cephalic femora armed with a row of stout spines, which 

 decrease gradually in size distad. Pulvilli present on four proximal tarsal 

 joints. Well developed arolia present between the simple and symmetrical 

 tarsal claws. Dorsal surface of male al)domen unspecialized. Interocular 

 space broad. Ocellar spots very small and inconspicuous. 



The genus temnopteryx is generally recognized as including 

 forms with short, quadrate tegmina, as opposed to Loboptera, in- 

 cluding forms with lobiform, lateral tegmina. We have not been 

 able to examine the genotype of the former. T. capcnsis, but from 

 material of other species at hand, it would appear very probable 

 that Temnopteryx will be found to be a synonym of Loboptera. 

 Hence we think it best to refer sakalava to the genus Loboptera. 

 This species, with L. indica Brunner, has tegmina intermediate 

 between the two types, these organs overlapping only in their 

 proximal portions, owing to the obliquity of their distal margins.

Tlie intricate, Iiiglily specialized male genitalia are distinctive. In the 

 remarkable subgenital plate the only difference shown by the males at hand 

 is a certain amount of variation in the size of the appendages. The teg- 

 minal venation is almost obliterated ; the anal sulcus is, however, conspic- 

 uous, transverse in its distal half, delimiting distinctlj' the greatly shortened 

 anal held. 



Small immature examples of this species have the antennae dark 

 l)rown, witli a broad whitish annulus distad. In addition to the pale 

 cephalic and lateral borders of the pronotum, the mesonotum is buffy in 

 proximal half and the first abdominal tergite is very narrowly buffy laterad 

 at the cephalic margin.
