10. C. hicosta Walker, Brit. Mus. List, Homopt. v. I., p. 



112, No. 14. Distant, Biol. Cent. Amer. Homopt. p. 

 7, pi. 3, fig. 1. 



Specimens cited by Mr. Distant were collected in 

 Mexico and Costa Kica. In my own collection there is a 

 female from Key West, Florida, captured by Dr. E. 

 Palmer, and a male from Cape St. Lucas, Lower Cali- 

 fornia, from the cabinet of John Xantns de Vesey. 



From the colored figure of the Biologia and examina- 

 tion of my own specimens, I find a close resemblance and 

 much agreement in structure between this and C. hicon- 

 ica Walk. The C. hicosta is a shorter winged and more 

 robust form. 



11. C. montezuma Dist. Biol. Cent. Amer. Hom. p. 8, No. 



6, pi. 2, fig. 2. 

 This species extends from the region of San Diego, 

 California, into Mexico, and from thence through Ari- 

 zona and Texas to the vicinity of the Pecos river in 

 New Mexico. It is quite distinct from our other native 

 species, is apparently not very variable in pattern of 

 marking, but it is decidedly variable in size. The great 

 prominence of the front renders it very conspicuous. 



12. C. riidis Walker, {Fidicina,) Brit. Mus. Cat. Hom. 



Supp. p. 13, Distant, Biol. Cent. Amer. Hom. p. 8, 

 No. 5, pi. 2, fig. 20. 

 Inhabits Eastern Mexico, and is much like a frag- 

 mentary specimen in my collection from Arizona. 



13. C. crucifera Walker, Brit. Mus. Cat. Hom. v. I., p. 

 196, No. 147, Distant. Biol. Cent. Amer. Hom. 

 p. 8, No. 5, pi. 3, fig. 6. 



A small, but interesting, form which has thus far 

 been found only in Mexico.
