34. Amblytropidia corumbae sp. nov. 



Very similar to A. interior in general appearance, but differing 

 from it in the larger size, the shorter hind lobe of the pronotum, and 

 in having fewer spines on the outer margin of the hind tibia 3 . 



Head of medium size, in the male about as wide as in the female, 

 a little narrower than the anterior margin of the pronotum. Vertex 

 prominent, the fastigium decidedly wider than -the narrowest part 

 between the eyes, rounded, cribrately punctate, and provided with a 

 strong median carina, which continues across the occiput; eyes prom- 

 inent, elongate, fully twice (9 ) or almost three times (o 71 ) the length 

 of the anterior edge of the cheeks below them. Frontal costa prom- 

 inent, broad, of equal width throughout, the lateral walls heavy, 

 in the male broadly sulcate throughout, in the female only below the 

 ocellus, but with the surface punctate above, the upper portion 

 between the fastigium and ocellus in both sexes exhibiting a coarse 

 median ridge. Antennae slender, filiform, in the female about as 

 long as the head and pronotum combined, in the male decidedly 

 longer. Pronotum quite strongly and cribrately punctate, its sides 

 parallel (o 71 ) or slightly expanding on the hind lobe (9), the latter 

 plainly shorter than the anterior one; anterior margin of the disk 

 gently rounded, the posterior edge obtusangulate, with a very slight 

 emargination on either side. Tegmina and wings fully developed, 

 a very little surpassing the apex of the hind femora; the former of 

 moderate width, without a definite intercalary vein, except towards 

 the outer portion of the area, where a trace of one is present, in the 

 female specimen before me. Hind femora somewhat slender and 

 elongate, the apical third noticeably more graceful than usual in
