greatest width of pronotum, 2; length of teginen, 13.2; length of 

 cephalic femur, 2.8. 



Westwood states that the species occurred in the forest on low

Acontiothespis-' brevipennis (Saussure)

 pi. 9, fig. 20. [Brazil.] 



Independencia, Parahyba. (Mann and Heath.) Three 

 males, one female. 



Baturite Mountains, Ceara. (W. M. Mann.) One male. 



Maranguape Mountains, Ceara. (W. M. Mann.) One 

 female. 

 This species was previously known only from the female sex. 

 It is evident that in both sexes it is close to A. himaculata and in 

 the male sex to the Central American A. vitrea, the female of 

 which is not available. All of the present series have been 

 immersed in alcohol and in consequence only structure and 

 wing pattern can be mentioned. In brevipennis, when compared 

 with himaculata, the male has the lateral margins of the facial 

 scutellum more arcuate, the pronotum is heavier with the 

 constricted caudal section more elongate, the dorsal line more 

 sinuate when seen from the lateral aspect, the tegmina bears a 

 small irregular more or less pronounced maculation of seal I rown 

 mesad on the discoidal field and the wings are immaculate hyaline. 

 From vitrea the male of brevipennis differs in the head being of a 

 slightly different shape, in the slightly shorter though similarly 

 shaped pronotum, which also is more decidedly constricted caudad, 

 and in the more numerous and closely placed spines on the 

 external margin of the cephalic tibiae. The female of brempennis 

 differs from the same sex of himaculata in the same features of 

 the head and pronotum as the males do, in the equally abbreviate

23 The genus Acontistes Burmeister, as has been pointed out by Saussure and 

 Zehntner (Biol. Cent.-Amer., Orth., i, p. 130, (1894), is preoccupied by Acon- 

 tistes Sundevall in Aves. The emendation Acontista of Saussure, 1870, was 

 not proposed as a replacement, but apparently as a correction in gender, and 

 in consequence is not available to replace the preoccupied name. As a new 

 name for Acontistes Burmeister is necessary, we here propose Acontiothespis.
