and E. A. Schwarz) ; Tucson, Ariz.. January (H. G. Hubbard and E. A.

Opuntia leptocaulis (E. A. Schwarz) ; Tucson, Ariz., in O. fulgida. 

 *Cactophag'us spinolce Gyllenhal (Syn.: validus Le Conte). (See Champion, 



Biol. Centr.-Amer. ) California, Arizona, Mexico, many localities. Larva 



and pupa figured by Duges (La Naturaleza, vol. 5, 121). 

 According to Duges breeds in " Cactus opuntia." 

 Caclophagns striatoforatus Gyllenhal. Attacks Cereus in Costa Rica and Co- 

 lombia. (Sec Champion. Biol. Centr.-Amer.. Coleoptera, vol. 4, 7, p. 84. 

 * Cactopinus hubbardi Schwarz. Forms mines in Cereus. 



LEPIDOPTEKA. 



Apantcsis urge Drury. 



Feeding on cactus. (See Forbes, 23d Rept. Ins. 111., p. 777, 100.".) 



Chorisagrotis soror Smith. San Antonio, Tex., February (D. Griffiths). 



Larvae had formed canals through underground portions of plants. A serious 

 enemy of young plantings. According to Dr. Dyar, it is probably a general 

 feeder and not confined to cactus. 



Mimorista flavidissimalis Grote. Widespread in Texas, south of San Antonio 

 and west of Victoria. Brownsville, Victoria, and Beeville (J. D. Mitchell), 

 San Antonio and Sabinal ( F. O. Pratt); May to September. A very 

 destructive insect, attacking joints of Opuntia. 



Cornifrons elautalis Grote. Hondo, Tex. (J. D. Mitchell) ; Tucson, Ariz. 

 Destructive to fruit. 



Dicymolomia opuntialis Dyar. San' Diego and Riverside, Cal., May (D. Grif- 

 fiths). Apparently forms mines in joints, but doubtfully included in this 

 lisl Sec following species. 



Dicymolomia julianalis Walker. Brownsville and Kerrville, Tex., June. Ap- 

 parently forms mines in joints, but it is very doubtful whether it should 

 be considered a cactus insect. Gahan (Proc. Ent. Soc. Wash., vol. 11, 

 p. 66) records it as a predator on the eggs of Thyridopteryx ephemerce- 

 formis Haworth. 



Ozamia lucidalis Walker. Victoria, San Antonio, and Hondo, Tex., May (J. D. 

 .Mitchell i. Infesting fruit. 



Melitara junctolineella Ilulst. Kerrville, Tex. (H. Lacy) ; Corpus Christi, Vic- 

 toria, Beeville, Hondo, Laredo. Tex. (J. D. Mitchell) ; El Paso, Kerrville, 

 San Antonio, Tex. (F. C Pratt). This and the other species of the genus 

 live within the joints of Opuntia. causing large swellings. The two dif- 

 ferenl kinds of cocoons seem to indicate that there are two species pres- 

 ent in the cactus area. The range of the two forms corroborates this 

 supposition. There are certain differences between the specimens, but they 

 are not sufficient to separate the series into two forms.
