A member of the same group as laticauda and riigripes, but 

 separable from the former by the relatively broader fastigium, 

 by the more extensive metazona of the dorsum of the pronotum 

 and the shorter and marginally more acute lateral lobes- of the 

 same, while from nigripes the male is readily separated by the 

 less strongly adpressed cereal tooth and the appreciably indi- 

 cated humeral sinus of the lateral lobes of the pronotum. The 

 female is separated from that of nigripes by the less angulate 

 ventro-cephalic angle of the lateral lobes and the generally un- 

 spined caudal femora, while from laticauda the same sex differs 

 in the sinuate ventral section of the caudal margin of the lateral 

 lobes. 



Type. — c^ ; Galveston, Galveston County, Texas. July 21,1912. 

 (Hebard.) [Hebard Collection Type No. 165.] 



Description of Type. — Size very large (for the genus); form robust. Head 

 with the dorsum of the occiput plane, hardly ascending to the fastigium, the 

 latter subcompressed, not as thick as the proximal antennal joint and when seen 

 from the facial aspect with its margins gently converging ventrad, with the 

 extremity at the interfastigial suture distinctly truncate; eyes moderately 

 prominent, subcircular in basal outhne; antennae very elongate, when in perfect 

 condition at least thi-ee times as long as the body. Pronotmii subsellate, when 

 seen from the lateral aspect the metazona is distinctly and in a subbullate 

 fashion ascending dorso-caudad, when seen from the dorsal aspect the meta- 

 zona is seen to be somewhat inflated laterad, its gi'eatest width about five-sixths 

 the length of the entire pronotum; length of the metazona about two-fifths 

 the length of the entire pronotum, transverse sulcus deeply and broadly im- 

 pressed on the dorsum; cephalic margin of disk weakly arcuato-emarginate 

 mesad, caudal margin of disk strongly and regularly arcuate, no indications 

 of lateral shoulders present on prozona, but on the metazona these are well 

 indicated and slightly projecting though well rounded; lateral lobes of the 

 pronotum with the greatest dorsal length subequal to the greatest depth, 

 cephahc margin oblique, straight, ventro-cephalic angle rounded obtuse, 

 ventral margin moderately oblique, ventro-caudal angle sharper than a right 

 angle with the angle proper strongly rounded, caudal margin oblique sinuate, 

 humeral sinus but faintly indicated, convex callosity well indicated but elongate 

 and narrow. Tegmina surpassing the apices of the caudal femora by about the 

 length of the pronotum, moderately broad, apex moderately rounded; stridu-
