MEXICAN ORTHOPTERA. 221 



Vales annectens Eehn. 



1900, Vates annectens Eehn, Trans. Am. Ent. Soc, xxvii, p. 85. 



One specimen, S ; Tacubaya, D. F,, November 11, 1898. 



Vates sp. 



One specimen, 9 (immature) ; Cuernavaca, Morelos, v. 



This very interesting specimen is unfortunately immature ; the 

 arrangement and form of the foliaceous lobes are apparently much 

 different from tho.se of any known species of the genus. While 

 somewhat resembling V. pectinata, it is clearly not the same, none 

 of the lobes being angular to the extent they are in that species. 

 The supra-coxal lobes are distinctly concave on their anterior mar- 

 gin. The information with the specimen is to the effect that it was 

 eating a Morpho when captured. 



Family GRYLLID^. 



Gryllus assimilis Fabricius. 



1775, Gryllus assimilis Fabricins, Syst. Ent., p. 280. 



Two specimens, <? and 9 ; Jalapa, Vera Cruz, viii. 



Gryllus barretti n. sp. 



Types: one male, three females; Cuernavaca, Morelos, v and vi. 



This interesting species closely resembles G. assimilis, but is 

 smaller and the oblique veins in the male number three. The ovi- 

 positor is proporti(jnately longer than in assimilis. The color of 

 the lateral field and the angle causes it to resemble capitatus from 

 South America, but that species possesses 5 6 oblique veins. I take 

 pleasure in dedicating this species to my friend, Mr. Otis W. Barrett 

 who collected the types. 



%. — Size medium. Head glabrous, except the posterior half of genae; eye 

 rather ovate, with no marked angles: antennae reaching the tip of the caudate 

 wings. Pronotum rather hirsute, this character most marked on the posterior 

 margin, which is very broadly rounded, the anterior slightly concave; lateral 

 lobes of greater depth anteriorly than posteriorly, the anterior angle narrowly 

 rounded. The dorsal field of tegmina with three oblique veins. Wings caudate, 

 extending beyond the tegmina to the length of the hind tibiaj. Limbs clothed 

 with two sorts of hairs, one long and hirsute, the other short and pubescent; au- 

 ditory organ of anterior tibiae elliptical; posterior tibiae with six spines in each 

 border, the apical spines fairly long. 



General color brownish black, the black pure on the head and pronotum. Teg- 

 mina with the branches of the mediastine vein yellowish. Limbs wood brown, 

 covered with a faint silvery pubescence.
