(P.juliflora), JNlay lo to 12. The henielytra are yellow, mottled with 

 brown. A specimen swept from alfalfa May 9 is determined by Dr- 

 Uhler, with a query, as this species. 



Cyrtolobus a?inexus, Uhler. 



Quite a number of this small brown tree-hopper were beaten from 

 flowers and foliage o{ P.juliflora May 10 to 12. Two larvK, apparently 

 belonging to this species, were beaten May 10. The larvae are also 

 brownish, 



Stidocephala inermis, Fab. 



Quite numerously swept from alfalfa May 9 to 28. The adults vary 

 from wholly green to largely reddish on upper portions. No larv^ 

 foimd. 



Gorgora atlas, Coding. 



Adults beaten, May 13 to 15, from twigs and leaves of Larrea 

 mexicana. Larvae were beaten May 15. The adults are of a rich dark 

 brown colour, and peculiar form. The larvae are greenish. Both adults 

 and larvae are not readily dislodged from the Larrea twigs or leaves, and 

 the adults rarely take wing. This was formerly determined by Dr. Uhler 

 as Ceiitrodojitus bimidulatus, Uhl. (prob. MS.). A specimen was sent to 

 Dr. Coding for insertion of the species in his catalogue, and he wrote me 

 that he had already described it as above, under a new genus. 



TypJilocyba vitifex, Fitch. 



I notice in Bulletin 19 of the Colorado Station that specimens of the 

 vine leaf-hopper, as it exists in Colorado, have been sent by Professor 

 Cillette to Professor Osborn and Mr. E. P. Van Duzee, who have 

 determined it as T. vitifex, Fitch. Our species in New Mexico is 

 apparently the same. I had always noticed the marked difference between 

 this and T. vitis in the markings of the hemelytra, but from the fact that 

 many authors accepted these as varieties of one species, I had preferred 

 to consider our form as a variety of the eastern one. Our form does not 

 possess the black spots at base of scutellum, as in var, coloradoensis, 

 Cillette. The larva is pale yellowish, with four black spots on the thorax. 

 Agallia 4-pufictata, Prov. 



This small, short, grayish leaf-hopper was swept in large numbers from 

 alfalfa May 9 to 28. Larvae were swept May 12 to 28. In coitu, May 28, 

 The larvae are also grayish. 

 Gypona angulata, Spang. 



Several of this species were swept from alfalfa May 12 to 28. It is
