from West Virginia. This is the common form in the Rocky 

 mountains and northern regions and extends down along the coasts 

 as far as Washington and San Francisco. It was the only form at 

 hand from California at the time the writer reviewed the genus. The 

 western specimens have the band on the pronotum somewhat 

 broken and the lower part of the face light, thus agreeing fairly well 

 with the description of Uneaticollis Stal and were so referred. Since 

 that time dark smoky forms of the species that was known at that 

 time as dclicata Uhl. have been found in California and as Baker 

 suggests they are undoubtedly the form that Stal described. 



Clastoptcra obtusa var. junipcrina n. var. 



Resembling tcstacca in ground color, but with the addition of a 

 definite pattern of narrow dark lines on the nervures of the posterior 

 part of the elytra, a band from the middle of the costa to just be- 

 fore the claval suture slightly irregular and curving around the 

 bulla, a medium-sized callosity, a crescent at the apex of clavus and 

 usually an arcuated transverse line setting off the anterior third of 

 the pronotum, a line at the base of the scutellum and a very small 

 spot at the extreme tip black. Sometimes a brown cloud extends 

 obliquely across the clavus from before the middle of the scutellum 

 towards the dark line in front of the bulla. 



Described from four examples from Palisades, Colorado, taken 

 by the writer. 



This variety occurs only on the red cedar and has been found in 

 all stages on that tree throughout the mountain regions of Colorado 

 and Utah. The ground color and dark penciling render this globose 

 species an almost perfect mimic of a dried strobile of this tree. 



Clastoptcra Uneaticollis var. higitbris n. var. 



Size and form of var. dclicata, but lacking its definite marking. 

 Dull smoky brown with faint indications of the transverse bands on 

 vertex and pronotum. A dark smoky cloud just before the inflated 

 portion of elytra and a large shining l)]ack callosity. Face shming 

 black. 



Described from a single female from Alameda county, California, 

 in the collection of the writer. Other examples from the same lo- 

 cality vary in having broader bands and on the pronotum and the 

 face with traces of light lines.
