156. Abracris meridionalis (Bruner). 

 Omalotetlix meridionalis Bruner, Biol. Cent. Amer., Orthopt., II, pp. 280, 281 



!u general appearance very similar to A. signatipes (Omalotettix 

 signatipes) Bruner, but decidedly larger than that species, from whi< h 

 it differs also 1>\ having the oblique fuscous bands of the hind femora 

 continuous with the transverse patch across the upper edge. The 

 tegmina and wings of meridionalis are comparatively longer than in 

 the species with which compared, while the former are darker in color 

 and have their veins more uniformly obscure. In meridionalis the 

 cerci of the male are nearly straight, rather evenly tapering, and have 

 the inner fork minute and shorter than the outer, as compared with 

 the somewhat curved form and strong inner toothed structure, as 

 found in signatipes. 



( General color of head, sides of pronotum. pleura, legs, and abdomen, 

 ferrugineo-testaceous, marked on head back of eyes, on the upper 

 portion of the sides and disk of pronotum, and on the pleura, with dark 

 brown, giving to these parts the appearance of being banded with the 

 pallid coloring. Antenna? testaceo-ferruginous. Hind femora marked 

 above by two strong bread transverse fuscous bands, the anterior or 

 basal one of which continues uninterruptedly obliquely forward upon 

 the outer disk two-thirds of the distance to its lower margin; the lower 

 outer margin of the femur is strongly marked with black. Hind tibiae 

 dark plumbeous, with a sub-basal pallid annulus in an infuscated 

 area, the apex also decidedly infuscated. 



Length of body, cf, 17.5 mm., 9, 23 mm.; of pronotum, cf, 3.6 

 mm., 9, 4-35 mm.; of tegmina, cf, 18 mm., 9, 23 mm.; of hind 

 femora, cf, 10.25 mm., 9, 12.4 mm.
