median emargiiiation the converging lateral margins cause the 

 lateral angles to appear as acute trigonal projections with their 

 immediate angles blunted. Cephalic femora nearly twice as long 

 .as the dorsum of the pronotum, slender; cephalic tihise appreciably 

 exceeding the femora in length, foramina elliptical. Median femora 

 subequal to the head, pronotum and tegmina in length, similar in 

 build to the cephalic femora; median tibiae exceeding the femora by 

 about the same proportion as in the cephalic limbs. Caudal femora 

 one and one-third times as long as the body, very moderately inflated 

 in the proximal half, slightly compressed, genicular lobes not dis- 

 tinctly spined, but with a minute point (sometimes absent) at the 

 .apex of each lobe; caudal tibise surpassing the femoral length by 

 about four-fifths the length of the dorsum of the pronotum.

Description of Allotype. — The following characters "are solely those 

 of difference from the above description of the type, features not 

 mentioned are essentially as in the male sex. 



Size large (for the genus); form robust. Head noticeably 



broad, the greatest width nearly equal to the depth of the 



■head as far as the clypeal suture; fastigium very brief, slightly 



elevated at the extremity; eyes moderately prominent, slightly 



compressed, ovoid, their depth contained slightly more than 



one and one-half times in the depth of the infra-ocular portion 



-of the gense; antennae about one and one-half times the length 



,of the body. Pronotum heavy, the dorsum more arcuate in 



section than in the opposite sex, caudal 



"width of the disk contained one and 



one-third times in the length of the 



same, greatest ventral width of the 



pronotum equal to about five-sixths Fig. 14. — Dichopetala pollicifera

of the length ■ 01 the dorsum of the allotype (X4) 



^ame; cephalic margin of the disk 



emarginato-truncate, caudal margin of the same moderately arcuate. 



no appreciable callous bounding lines present on the disk, which 



rounds into the lateral lobes; transverse sulcus weakly indicated, 



placed mesad and on the middle of the disk impressed in a broad, 



\'-shaped figure; lateral lobes with the greatest depth contained 



one and two-thirds times in the dorsal length of the same, margins 



as in the males but with the ventro-cephalic angle blunter. Tegmina 



with their apparent length about one-fourth that of the pronotum, 



their greatest width nearly two and one-half times their visible
