Oiiginallv described fruin Albu- 

 querque, N. Mex. (Bruncr), it has 

 since been recordeil from Las Cruces, 

 N. Mex. (Townsend), and Panamint 

 Valley, Cal. (Riley). I have received 

 it from Las Cruces (Townsend) and 

 Mesilla, N. Mex., July i (Morse), 

 as well as from Juarez, Max., Jul}' 3 

 (Morse). Mr. Morse tells me that it is 

 a common insect at Mesilla, found on 

 sand hills and the gravelly mesa, 

 where it is almost invisible, the color 

 and markings varying with the local- 

 ity ; it flies freely, but not far.

This species was described by 

 Thomas from specimens taken by 

 Crotch in .Southern California, and has 

 since been mentioned as foimd at Los 

 Angeles, Cal. (Coquillett) , and in the 

 Cerros Isl. off the coast of Lower Cali- 

 fornia (Bruner). I have seen specimens 

 from San Diego (Crotch), Tndio, July 

 9 (Morse), Palm .Springs, J^dv y 

 (Morse), Mohave, Cal., Aug. i 

 (Moise), and Rock Spring in south- 

 eastern California (Palmer), as well as 

 from some other unspecified point in 

 California, collected by Osten Sacken,* 

 who reports it as found '• among boul- 

 ders of granite, the colors of which it 

 seems to mimic." I have it also fiom 

 St. George, Utah, .Apr. 1-12 (Palmer), 

 from Saltillo, Mex., ?\Iar. 21-28 

 (Palmer), and Sonora (Schott), as well 

 as fiom Cape St. Lucas, Lower Cali- 

 fornia (Xantus).

Of small size, cinereo-testaceous, more or 

 less embrowned above on head and prono- 

 tum, marked witli brownish fuscous, the 

 face, genae, lower portion of lateral lobes 

 and sometimes their whole metazonal por- 

 tion overlaid with chalky white. Head 

 prominent, the sculpturing much as in H. 

 californicus lint the face retreating more; 

 eyes rather prominent, especially in male; 

 antennae short, about half as long as the 

 hind femora, in no way attenuate or de- 

 pressed at apex, fusco-testaceous, feebly in- 



* Baron Osten Sacken collected Ortlioptera in Sonoma 

 and Marin Cos. uortli of San Franciscti, but this insect 

 has not otherwise been reported from so northern a 

 locality, or farther north than Mohave.
