A A. Larger, with the elytra longer ( 9 , 23 mm. or more). 



b. Posterior margin of the disc of the pronotum entire. Tegmina a little 

 wider at middle than the length of the anterior femora [Bolivia].

 4. Oxyprorella zebrata sp. nov. 



Ferrugineo-testaceous, more or less mottled and streaked with 

 fuscous and black. Body hirsute. Head a little wider than the 

 anterior margin of the pronotum; eyes large, prominent, a little longer 

 than wide, alternately streaked lengthwise with fuscous and testa- 

 ceous; fastigium of the vertex depressed, sulcate, decidedly narrower 

 than the first antennal joints; fastigium of the front prominent, white, 

 almost reaching the upper end of the antennal scrobes. Antennae 

 annulated with fuscous. Pronotum short, the disc flat above with 

 prominent lateral carina^. Tegmina somewhat coriaceous, of moder- 

 ate width, the apex obliquely truncate; anterior and posterior radials 

 separated both near the base and apex, attingent between, the branch 

 of the posterior one given ofT in advance of the middle, both of the 

 forks running out at the apex. Anterior femora in front provided 

 with a single large tooth-like spine near the apex; intermediate pair 

 with two smaller spines; hind femora with several rather prominent 

 spines; anterior and intermediate tibiae dilated near their base, the 

 auditory apparatus wide open. Cerci heavy at base, rather long, 

 arcuate, the apical half slender. Sub-genital plate rounded, sub- 

 truncate at apex. 



Front infuscated and marmorate with flavous or testaceous and 

 rather closely punctate with fuscous dots from which eminate short 

 pale hairs. Pronotum with the lateral carinae and hind border black. 

 Tegmina with a few irregular scattered and five regular oblique fuscous 

 blotches, — the latter on the apical half of the costal field. Exposed 

 portion of wings also so marked. Anterior femora and tibiae basally 

 striped in zebra fashion with black. Hind femora also showing dim 

 bands of fuscous. Cerci for the most part black, the center ferrugi- 

 nous. 



Length of body, cf, 13 mm., of pronotum, 2.85 mm., of tegmina, 21.5 

 mm., width of same, 5 mm., length of wings, 26.5 mm., of hind femora, 

 15 mm.
