with nine, on the internal margin with ten spines, internal distal spurs sul)- 

 equal in length, external distal spurs distinctly sliortcr than the internal, sub- 

 equal in length to one another. 



Allotype. — 9 ; Same data as type. [Acad. Nat. Sci. Phila.] 



Differing from the description of the male in the following features. 



Fastigium when seen from the side more arcuate, the fastigio-facial angle 

 more broadly rounded and less prominent than in the male; fastigium slightly 

 broader, even more shallowly excavate, margins subobsolete; inter-antennal 

 section of the frontal costa slightly less produced when seen from the side: 

 frontal costa of the general form found in the male but broader, with the sul- 

 cation rather shallower: eyes somewhat less prominent than in the male, in 

 basal outline slightly less broadly ovate than in the male, in depth equal to 

 one and one-fourth times the length of the infra-ocular sulcus: antermae in 

 length subequal to the length of the head and dorsum of the pronotum com- 

 bined, slender. 



Pronotum with disk one and one-third times as long as greatest width, 

 median carina subobsolete on the metazona, entirely obsolete on the prozona; 

 prozona of disk very slightly longer than the metazona of the same: median 

 angle of the ventral margin of the lobes of the pronotum not rounded. Teg- 

 mina of similar length, but distinctly l>roader, being broad ovate in outline, 

 greatest breadth contained one and one-fifth times in the greatest length, apex 

 broadly rounded obtuse: sutural margins narrowly overlapping. Interspace 

 between the me-sosternal lobes transverse, its width sul)e(iual to that of one of 

 the lobes, interspace regularly enlarging caudad, meso-caudal angle of lolies 

 obtusely rounded: interspace between metasternal ]ol)es moderately trans- 

 verse. 



Ovipositor jaws moderately elongate, sul)compressed, dorsal valves with 

 dorso-external margins moderately denticulate. 



Cephalic and median femora almo.st uninflated. 



General color of head, pronotinn and ])l('ura ])russels brown (allotype) to 

 mummj' brown (type). 



Head in female unicolorous; in male with the occiput and postocular region 

 washed with fuscous, the ventral section of the genae, face and (weakly) the 

 mouth-parts washed with carmine (type) to garnet brown (paratype); eyes 

 buckthorn })rown to bay; antennae (lacking in male) washed with hay's russet. 



Tegmina of male with costal half blackish brown, occasionally (type) 

 weakened to raw urrjber in portions of the marginal field ; sutural half of male 

 tegmina deep chrome to mustard yellow, the two sections sharply divided: 

 tegmina of female uniformly of the general color. 



Abdomen of both .sexes with the proximal section shining l)lackish l)ro\vn 

 laterad; dorsum of abdomen of the general color in the male, with paired naples 

 j'ellow dots indicated on the second, third, fourtii and fifth .segments with 

 greater or le.ss distinction; distal portion of aljdomen of male largely brownish 

 olive dorsad; of the female of the general color: venter of abdomen of male
