Genus Alota Bruncr. 

 .4/0/0 Bruner, Ann. Carnegie Mus., VIII, pp. 446, 454 (1911). 



The genus Alota was established by the present -writer on the 

 strength of a single male specimen from the Rio IVIachupo in Bolivia. 

 It belongs to the group Scyllinina: as shown by the size and form of 

 the inner hind tibial spurs. 



56. Alota boliviana Bruner. 



Alola bolniana Bruner, /. c, p. 454 (191 1). 



This species was described, as stated above, from a single male 

 specimen. 



We now have a female which also belongs here. It was taken by 

 J. Steinbach at Las Juntas, in the Department of Santa Cruz, Bolivia, 

 in December, 1913, at an altitude of 250 M. above sea-level. C. M. 

 Ace. No. 5060. 



This specimen in its type of coloration and general appearance at 

 first glance recalls one of the larger species of OrphiileUa, and also of 

 the representatives of the genus Parorphula. However, the entire 

 absence of lateral pronotal carinae and the structure of the tibial 

 spurs at once carry it to Alota in the synoptic table of the South 

 American genera of the Truxalidje. The tegmina have the costal and 

 discal fields infuscated, the former varied with a series of pale spots, 

 which give to that area a longitudinal maculate appearance. This 

 female specimen has but six spines on the outer margin of the hind 

 tibiae instead of seven, as described for the male type. Still I feel 

 satisfied that it belongs to the species boliviana. 



Length of body, 9 , 19 mm.; of pronotum, 3.85 mm.; of tegmina, 

 19 mm.; of hind femora, 12 mm. 



Genus Scyllina Stal. 

 Scyllina StAl, Recens. Orth., I, pp. 94, 112 (1873). For further synonymy see 

 Annals VIII, p. 35 (1811). 



This is certainly an important genus in tropical American countries, 

 where its representatives are widely distributed and among the most 

 abundant of locusts. Some of them even become destructive to 

 crops and forage-plants in their respective localities.
