ocular lines of the head, subparallel caudad to the transverse sulcus 

 and thence distinctly but not greatly diverging (male), or regularly 

 but very gently diverging throughout their entire length (female). 

 Tegmina with the dorsum darker than the marginal field, the venation 

 of the pale general color on a darker, nearly wine-colored, background, 

 humeral trunk of the darker color. Abdomen with the dorsum of the 

 proximal segments in the male narrowly edged cephalad with seal 

 brown, this portion like that similarly colored on the occiput proliably 

 normally concealed; the dorsum of the abdomen separated from the 

 sides by a more or less distinct line, which in position is continuous 

 with the postocular line of the head and pronotum; caudal margin 

 of the dorsal segments in the female more or less distinctly and 

 broadly edged Avith darker color. Limbs more or less decidedly 

 washed with madder brown, a slight edging of the same color on the 

 dorsal margin of the ovipositor, the terminal teeth of the same tipped 

 with seal brown. 



Distribution. — This very striking species is only known from the 

 type locality, the territory of Tepic, western Mexico. 



Specimens Examined. — 2; 1 male, 1 female. 



Tepic, Mexico, (Eisen), 1 cT, 1 9. Type and allotype. [Hebard 

 Collection.] 

 Dichopetala serrifera n. sp. 



On account of the peculiarly serrate cerci of the male, this species 

 occupies a unique position, and comparison with other forms is not 

 necessary. 



Type: cT ; Barranca, twelve kilometers north of Guadalajara, 

 state of Jalisco, Mexico. Altitude not less than 3,500 feet. Septem- 

 ber 13, 1933. (W. L. Tower.) [American Museum of Natural 

 History.] 



Description of Type. — Size medium; form subcompressed. Head 

 with greatest width contained about one and one-half times in. 

 greatest depth; occiput moderately declivent to fastigium and 

 antennal scrobes; fastigium low, acuminate, faintly sulcate dorsad, 

 ventrad subattingent with frontal fastigium; eyes moderately 

 prominent, reniform in basal outline, depth about two-thirds that 

 of the infra-ocular portion of the gense; antennae incomplete. Pro- 

 notum moderately sellate, greatest ventral width about five-sixths 

 that of the dorsal len2;th of the pronotum, greatest caudal width of 

 disk about two-thirds length of same; cephalic margin of disk very
