Coloration. — cf. This sex shows less color variation than in 

 other species of the genus. General coloration ochraceous-buff. 

 A brown, shield-shaped marking is situated meso-caudad on the 

 pronotum, this is normally finely and weakly marked with a darker 

 shade (a conspicuous development of this darker pattern gi\ing 

 the allied a pacha a distinctive pictured appearance). In rare 

 specimens of extreme recessive coloration, this blotch becomes very 

 pale, with no darker markings whatever. In specimens of extreme 

 intensive coloration it becomes dark brown, the markings again 

 disappearing. In the other species of the genus, we find, in the 

 maximum of intensive coloration, that the homologous pronotal 

 blotch expands, covering all but the cephalic margin of the prono- 

 tum; this does not appear in any of the very large series of erratica 

 now before us. 



9 . General coloration, above tawny to burnt umber, the 

 cephalic margin of the pronotum usually vaguely paler, all but 

 the darkest individuals faintly maculate on the pronotum, mesono- 

 tum and metanotum with a darker shade, and laterad a spot of this 

 same color is found, with rare exceptions, in the series before us, 

 on each abdominal segment both above and below. Minute hairy 

 covering tawny. I'nderparts, particularly head and limbs, some- 

 what paler. 



This species is know^n to range from Waco, south to Goliad and 

 Brownsville, Texas. Westward the most northern localities are 

 Ballinger, Texas; Durango, Colorado; Mescalero Apache Reser- 

 vation and Jemez Hot Springs, New Mexico; Adamana and W'ins- 

 low^ Arizona, and St. (leorge, I'tah; while in California the species 

 is known only from single records — Cottonwood and Ri\erside. 

 The species undoubtedly has an extensive distribution in Mexico,
