334 ENTOMOLOGICAL NEWS. [Nov., '06 



Size rather large ; cephalic and thoracic regions thickly but bluntly 

 tuberculate. Head greatly prolonged, particularly in the male, the por- 

 tion . immediately caudad of the eyes strongly and roundly constricted 

 in the male; the length considerably more than half the length of the 

 prothorax in the female, very slightly more in the male; vertex in I he 

 male a quadrate peg-like process, shorter than the length of the eye. 

 slightly tapering and with the apex truncate, in the female quadrate 

 with the angles more acute, equal to the length of the eye, hardly taper- 

 ing, the apex bluntly rounded ; antennae very short, about twice the 

 length of the rostrum in the male, very slightly longer in the female: 

 eyes very prominent in the male, ovate in outline when viewed laterad. 

 approaching closer cephalid than caudad, in the female moderately promi- 

 nent. Prothorax elongate, the greatest width (inter-coxal) contained 

 nearly nine times in the length in the male and about five and a half 

 times in the female, cylindrical in the male, somewhat depressed in the 

 female ; cephalic margin subtruncate mesad. slightly expanded laterad ; 

 caudal margin sinuato-truncate, very slightly expanded in the male and 

 not appreciably so in the female; no median carina present in the male, a 

 very blunt and low one present in the female, weak mesad ; prosternum 

 separated from the pronotum by a distinct sulcus. rounded in the male, 

 tectate in the female with the central ridge bearing a slight shallow 

 median sulcus; coxae shielded cephalad bv a rounded projecting plate, 

 more prominent in the female than in the male. Mesothorax consider- 

 ably depressed, the pronotal carina continued caudad on the mesonotum 

 in the female; mesopleura tuberculate. not spined. Metathorax about 

 equal to the mesothorax in width, somewhat depressed caudad in the 

 female. Abdomen very considerably longer than the head and thorax, 

 cylindrical in the male, with a median carina in the female; supra-anal 

 plate of the male half ovate, cerci very short. Cephalic femora about 

 half the length of the pronotum in both sexes, very slightly enlarged 

 distad, tibias about equal to the femora in length. Median femora and 

 tibiae about equal in size and form to the cephalic in the female but 

 more robust, in the male distinctly shorter than the cephalic. Caudal 

 femora about equal to the prothorax and mesothorax in length, very 

 slightly longer than the same segments in the female, slightly inflated 

 in the proximal half, dorsal margin of the genicular region with a spine 

 on each side ; caudal tibia? very slightly longer than the femora, sub- 

 quadrate in section, slightly but distinctly arcuate, the outer dorsal 

 margins with thirteen to sixteen spines, the inner dorsal margins with 

 six to nine spines. 



General color olivaceous brown, mixed with tawny-olive, particularly 

 in the male and on the pronotum in the female. Eyes clove-brown in 

 the male, of the general color in the female.
