apical and anteapical areoles. Veins white, 

 claval suture brownish. Face and legs tinged 

 with greenish, some of the white tibial spines 

 brown tipped. Tarsal joints at apices dark. 

 Dorsal abdominal segments except lateral 

 and apical margins blackish. 



Described from a single male taken at 

 San Augustine (Ckll. 2140).* In form, this 

 insect very closely resembles P. superbits 

 and in structure is strictly congeneric with 



it. It differs very widely, however (and this 

 is a generic difference according to Van 

 Duzee's synoptic table of the genera), in 

 that it does not possess the elytral reticula- 

 tions or other markings so characteristic of 

 the genus. On a very superficial examina- 

 tion it might be taken for a Chlorotettix, 

 but its general form, stronger build, and 

 lengthened vertex are strictly Phlepsiid. 



VII. The Grape-Vixe Typhlocybids of the Mesilla Valley, N. M. 



At Las Cruces and Mesilla, N. M., the 

 grape-vine suifers, as in other parts of the 

 U. S., from the attacks of small Typhlocy- 

 bidae. in most seasons not seriously destruc- 

 tive, but occasionally very abundant and 

 troublesome. Two species are found on the 

 Mission Grape ( Viti& vinifera) at Las Cruces 

 in about equal numbers, often on the same 

 leaves. After making a slight study of them, 

 I determmed that they were different from 

 the eastern forms, and apparently unde- 

 scribed. This October I collected a number 

 and sent them to Prof. Gillette, who reports 

 that one is Typhlocyba coloradensis (Gill.), 

 hitherto only recorded from Colorado, but 

 perhaps properly regarded as a variety of 

 T. comes Say. The other is a new species 

 of Drcraneiira, described below. The genus, 

 Prof. Gillette says, has only two hitherto- 

 described species in U. S., one of these being 

 not from the U. S. proper, but from Alaska.

 tinct markings, in some specimens washed 

 with dilute sanguineous with light spots on 

 the posterior margin next the eyes. Pro- 

 notum : The breadth is twice the length, 

 moderately concave behind, color like that 

 of the vertex and, when washed with san- 

 guineous, there is a distinct whitish spot on 

 the middle of the anterior margin next the 

 vertex. Scrilellum without distinct markings

and agreeing with the vertex and pronotum 

 in color. £/v/''« pale* straw yellow crossed 

 by a narrow band of bright cherry red varying 

 some in depth of color but plainly discernable 

 in all mature specimens. The band crosses 

 just before the middle of the clavus, and that 

 portion of the band that is above the claval 

 suture is pushed forward so that only about 

 half of its width comes against that portion 

 which is upon the corium ; just beyond the 

 cross nervures is a jet black spot lying in the
