The type and topotype were taken in a region of extreme aridity 

 which probably explains their small size and coloration, which 

 latter is paler than in females from the Pacific coast. Rather 

 decided individual variation in size is, however, further shown by 

 the series before us. 



Coloration. — cf. (Intensive. Two, Mount Shasta, and one, 

 Sonoma County, California.) General coloration of head, pro- 

 notum, abdomen, limbs and tegmina shining prout's brown, the 

 tegmina translucent, the dorsal surface of the abdomen shading 

 proximad to ochraceous-buff. Ocelli ochraceous-buff. Wings 

 hyaline, all but the proximal portion of the anterior field w'eakly suf- 

 fused, the area of the costal veins heavily suffused with prout's 

 brown. In the paler conditions these areas are similarly suffused, 

 but with the paler color of the tegmina. (Intermediates; to dif- 

 ferent degrees, all of the remaining series except the three reces- 

 sive examples.) Head, underparts and limbs tawny russet. Ocelli 

 light buff. Pronotum tawny, occasionally slightly paler toward 

 the lateral margins. Tegmina transparent buckthorn brown, mar- 

 ginal field and distal portions paler. Dorsal surface of abdomen 

 ochraceous-tawny. (Recessive. Two, Fresno, and one. Riverdale, 

 California.) General coloration ochraceous-buff suffused with 

 tawny, ventral surface of abdomen mesad and distad shading to 

 tawny. Head russet, except ocelli and clypeus which are ochra- 

 ceous-buff. 



9 . (Topotype. Recessive.) Shining bay in general coloration, 

 becoming slightly darker on dorsal surface of abdomen. Ocellar 

 spots buffy. Limbs auburn. The specimens from Cahon Pass, 



'-^ The length of the exposed portion of the female tegmen is given. 



^-^ This specimen is dried alcoholic and shrivelled, this dimension is approximate.
