Bruner : South American Tetrigid^. 129 



Head with the suniniit comparativ'cly plane and depressed below the 

 prominent subglobular eyes, the surface sparsely granulose, only about 

 two-thirds the width of one of the eyes; the vertex not advanced in front 

 of the eyes and with the lateral carinte abbreviated and inconspicuous; 

 frontal costa rather profoundly sulcate nearly to the very top, the upper 

 end of the costa not following the median sulcus of the summit of the head 

 towards the occiput. Antennse long and slender, nearly or quite as long as 

 the hind femora. Pronotum finely granulate, only gently tectate, the me- 

 dian carina slender but quite prominent, viewed laterally gently undulate 

 a trifle ascending just before the front edge, which is angulated at middle 

 and terminates in an acute downwardly curved spine; the apex or hind 

 border bluntly acuminate, not quite reaching the tip of the abdomen in 

 either sex. Tegmina small, oblong, wings very abbreviate or entirely 

 wanting. Hind femora rather robust and passing the tip of the abdomen 

 in both sexes. 



Dark mahogany brown above, in some specimens with darker mottlings 

 on the carinae and disk of pronotum. Face, cheeks, and lower lateral 

 edges of pronotum obliquely testaceous. Pleura, sides of abdomen and 

 hind femora both interiorly and exteriorly fuscous varied with irregular 

 paler markings, the tibiae and tarsi annulate. Tegmina of males and some 

 of the females provided near the apex with a small testaceous or flavous 

 circular spot. Underside of male abdomen dirty white, the pectus 

 marked as in T. hancocki, in the female the meso- and metasternum 

 black. 



Length of body, cf, 7.5 mm., 9, 10 mm.; of pronotum, cf, 6.5 mm., 9, 

 8.5 mm.; of hind femora, cT, 5.25 mm., 9, 7-5 mm. 



Habitat. — Para and Rio de Janeiro, Brazil, during September. Also 

 at Chapada during the months of March, April, August, and November. 

 Both sexes taken by H. H. Smith. Carnegie Museum, Pittsburgh. 



Possibly this insect should be referred to the genus Batrachidea, in 

 which case it would come closest to the species B. mucronata of Serville, 

 which has the pronotum much longer and in some instances has the wings 

 even exceeding the pronotum in length.
