have reason to believe that the locahty is in San Diego County, 

 but numerous efforts to place Tighes have been unsuccessful. In 

 Nevada we have only a single record from Crestline, Lincoln 

 County Two of the records given for che species from California 

 are indefinite county records, Los Angeles and San Bernardino 

 Counties, and we are unable to say where in these geographically 

 varied areas, comprising parts of the Mohavan desert, the elevated 

 Sierra Madre ranges and the coastal valley section, the species 

 occurs. The occurrence of the species at Crestline, Nevada, at a 

 considerable elevation and north of the Mohave Desert leads us to 

 believe that it will be found to have a rather extensive distribution 

 over the mountain ranges of the great Basin. Two of the exact 

 Californian records are in the coastal region, the other (Cahon 

 Pass) being at the summit of the divide between the coastal and 

 Mohavan regions. 



We have or can ascertain elevations for but three of the records ; 

 2500 feet (San Jacinto River), approximately 3800 feet (Cahon 

 Pass) and 6000 feet (Crestline). 



Biological Notes. — All we know regarding the habits of this spe- 

 cies is that' it was taken at Crestline in bunch grass near junipers 

 (Juniperus utahensis), where there was hardly any other vegetation. 

 The locality is on an elevated gently rolling plateau, covered with 

 scattered groves of juniper and occasional pinon. Here the ground 

 is pebbly and practically bare in the groves, while in the open are 

 tracts of sage brush and areas of scant grasses and occasional low 

 yellow-flowered bushes. 



The dates of occurrence are few, these extending from July 18 

 (Cahon Pass) to September 4 (Cresthne). 



Morphological Notes. — In the male sex there is some variation 

 in the extent of the bullation of the pronotum and quite a little 

 in the degree of concavity of the dorsum of the same, the type 

 representing one extreme while the other approximates carita in 

 this respect. The degree of bullation appears in large measure to 

 be due to the handling in pinning and to the drying process. The 

 cephalic margin of the pronotal disk varies in shape from that 

 found in the allotype to one which is very broadly obtuse emargin- 

 ate, while the caudal margin varies from semicircular to roundly 

 obtuse-angulate in outline. The number of rami to the discoidal 

 vein in the male varies from two to five, one individual having
