Eremoblatta hirsuta new species (Plate IX, figures 21 and 22.) 



Closely related to E. siibdiaphana ; readily separated by the 

 proportionately deeper pronotum and heavier clothing of hair in 

 both sexes, a male genital character and tegmina moderately 

 glassy, with discoidal sectors longitudinal in that sex, and by the 

 narrower clypeal swelling in the female. The male also appears to 

 have the eyes wider apart and the face more deeply cleft between 

 and below the ocelli, but these features can not be exactly deter- 

 mined, as some distortion has taken place from immersion in.

Type. — cf ; Sierra El Tosti, Lower California, Mexico. Octo- 

 ber, 1893. [Hebard Collection Type no, 409.] 



Description of Type. — Size relatively very small, form acute ellijUical. Head 

 with width between eyes decidedly greater than that between the ocelli, which 

 latter are ver}- large and prominent, with face between and below these very deeply 

 cleft. Pronotum very deep, proportionately much less transverse than in snb- 

 diaphana, cephalic margin roundly angulate mesad at slightly less than 90°, caudal 

 margin weakly convex, surface of pronotum covered with minute hairs, cephalic 

 margin more thickl\- clothed with much longer hairs (in greatest length 1.2 mm.). 

 Tegmina less elongate than in siibdiaphana, discoidal sectors longitudinal, parallel 

 to both costal and sutural margins, pro.ximal surface of tegmina supplied with scat- 

 tered, minute hairs. The genitalia are of the peculiar and complex nature of siib- 

 diaphana, differing only in the appendage situated beside the concealed genital 

 hook, which is of different shape — proximad broad and subchitinous, distad pro- 

 duced in a brief, chitinous spine, less than half as long as is this projection in siib- 

 diaphana. 



Allotype. — 9 ; San Jose del Cabo, Lower C^alifornia, Mexico. 

 [Hebard Collection.] 



Description of Allotype. — \'ery similar to this sex of siibdiaphana. Cl\'i)eal swelling 

 narrower, extending from the slightly broader, flattened, distal margin of the clypeus 

 to a line drawn across just below the antennal bases. Pronotum proi)ortionately
