previous records being from the Huachuca Mountains and Oak Creek 

 Canyon, Arizona, and without exact data from the southern portion 

 of the same Territory. 



UDEOPSYLLA. Soudder. 

 Udeopsylla socorrensis (Rehn). 



This species, which was described as a species of Phrixocnemis , 

 should be placed in the genus Udeopsylla , probably with U. franciscanus 

 and vierecki representing a new subgenus. The structure and arma- 

 ment of the caudal tibiae are quite different from the type found in 

 U. robusta, but with the small amount of material available it seems 

 best to defer any division until an opportunity to examine a more 

 extensive series presents itself. A single male of this species from 

 Fort Wingate, collected May 12, 190S, by John Woodgate, has been 

 examined. The only previous record for the species is that of the types 

 from the Magdalena Mountains, New Mexico. 



GRYLLIDiE. 

 ECTATODERUS Guerin. 

 Eotatoderus borealis Scudder. 



A single nearly mature female of this species was taken from a dead 

 yucca on the greasewood slope between Alain ogordo and Dry Canyon. 

 July 13. Two adult females taken in the Florida Mountains in Novem- 

 ber by Dr. H. A. Pilsbry have also been examined, as well as a male 

 from Claremont, California, taken by Prof. C. F. Baker. 



The Alamogordo specimen has the lateral lobes of the pronotum 

 quite blackish, but this is not the case with the Florida Mountain 

 females, although present in the Claremont male. Its absence may 

 be due to the fact that the specimens in which this coloration is absent 

 were collected in alcohol. 



The previous New Mexican records of this species were from La 

 Cueva and Dripping Springs, Organ Mountains. 



NEMOBIUS Scudder. 

 Nemobius neomexicanus Scudder. 



Three specimens of this species, one adult male, one adult female 

 and one immature individual, were taken at Alamogordo, July 16, in 

 long grass under cottonwoods in the irrigated town park, where the 

 species was abundant. 



Both of the adults have the wings shorter than the tegmina, but- 

 otherwise they fully agree with an individual from Florence, Arizona. 



The species has been recorded from Las Cruces and Mesilla, New
