The above measurements show decided size variation in the 

 species, irrespective of geographic distribution. This feature 

 appears to be found in all the species of the subfamily, of which 

 we have sufficient material for such study. In the present series, 

 frequent small males have distinctly more ample tegmina and 

 wdngs than larger individuals of the same sex. 



Coloration. — All of the material before us from Lower California 

 is dried alcoholic, but the colors appear to have been changed little, 

 if at all. 



cf. General color light buff. Eyes blackish brown. Inter- 

 ocular space to betw^een the ocelli, dark chestnut browm; other 

 portions of head, underparts and limbs of general coloration. 

 Pronotum of general coloration, with a large, meso-caudal, uni- 

 formly colored blotch of ochraceous-buff, to deep chestnut brown. 

 This marking is sometimes broadly shield-shaped and not con- 

 tinued to the caudal margin of the pronotum ; frequently it is con- 

 tinued to that margin, while in some specimens the marking ex- 

 pands over the entire pronotum, leaving but a narrow^ band of the 

 pale general coloration on the cephalic margin, extending to, and 

 including, the caudal angles. Tegmina of general coloration, 

 slightly more glossy than is usual in erratica, more or less marked 

 with very fine maculations of a slightly darker shade. The 

 tegmina are frequently darkened at the base of the anal sulcus; in 

 some blackish brown, with base of the humeral vein the same color.
