eyes broad subovoid, the greatest width about three-fourths of the 

 length, not prominent when viewed from the dorsum; antennae 

 sUghtly longer than the head and pronotum together. Pronotum 

 with the greatest dorsal width about two-thirds of the length, the 

 width of the dorsum subequal except for the faintest widening near 

 the caudal margin; cephalic margin truncate, caudal margin obtuse- 

 angulate with the immediate angle broadly rounded; median carina 

 distinct, sharp, but not high; lateral shoulders narrowly rounded; 

 transverse sulci three in number, the caudal one placed slightly 

 caudad of the middle; lateral lobes with the greatest dorsal length 

 greater than the depth, ventral margin broadly obtuse-angulate 

 with the cephalic portion sinuate; surface of the dorsum and lateral 

 lobes, aside from the usual glabrous area on the prozona of the 

 lateral lobes, strongly impresso-punctate, on the dorsum rugulose, the 

 rugae arranged in a crudely linear fashion on the metazona. Tegmina 

 surpassing the tips of the caudal femora by nearly the length of the 

 head, narrow, the apex completely rounded. Prosternal spine 

 strongly retrorse, blunt conical, nearly in contact with the mesoster- 

 nal margin; interspace between the mesosternal lobes decidedly 

 longitudinal, the length contained about twice in the width, the 

 margins slightly diverging caudad, the angles well 

 rounded; metasternal lobes in contact for the greater 

 portion of their length, the suture linear. Furcula 

 very minute, subparallel, closely placed, linear lobes; 

 supra-anal plate subtrigonal in general form, the Fig. 15.— Le- 

 margins rounded, the apex obtuse, proximal half with utus\. sp. 

 a well-impressed medio-longitudinal sulcus ; cerci Lateral 

 falcate, considerably^ exceeding the supra-anal plate j^pg^ of ab- 

 in length, the proximal third broader, sharply narrow- d o m e n 

 ing, thence subequal to the tapering, acute distal (^ >< 4 ) 

 extremity, when seen from the dorsum the form of the 

 cercus is slightly sigmoid; subgenital plate considerably produced, 

 narrowing, when seen from the side straight except for a slight 

 •proximal arcuation, apex blunt, rounded. Caudal femora with 

 their tips very slightly surpassing the apex of the abdomen; caudal 

 tibiae armed on the external margin with nine spines. 



General color russet dorsad, becoming mars brown on the pro- 

 notum, ventral surface wax yellow; a pair of more or less distinct 

 subparallel clove brown lines extend from the fastigium caudad to 

 the caudal margin of the dorsum of the pronotum, the area between 

 these on the head wax yellow caudad, on each side a narrow line of
