at base of scutellar and first intervals; conjoined spots at bases of 

 third, fourth, and fifth intervals meetmg yellow lateral margin, latter 

 spots rarely reduced or absent; an oblique spot at about middle of 

 second and third intervals, often reduced or vague, rarely absent; 

 lateral margin at base to about middle apically joining an oblique 

 lateral spot; two anteapicai spots, often reduced or joined; one apical 

 spot sometimes reduced. With eight rows of punctures, fifth shortened, 

 usually sixth and seventh confused (or only sixth), sixth interrupted 

 or reduced at middle; inner and outer rows distinct at apex, usually 

 clearly meeting. 



Prosternum: Anterior margin in female evenly arcuate, not pro- 

 duced ; anterior margin in male somewhat produced into a broad lobe. 



Length: 3.7 to 4.8 mm. 



Discussion. — Schaeffer (1933, p. 462) described erect spinelike 

 processes at the apex of the prosternum in the male. These are actually 

 at the base of the prosternum and appear to be ventral extensions 

 of the paired processes normally present in members of this genus. 



The male holotype bears Schaeffer's identification label and is 

 thereon designated as type; it bears USNM type number 69090. 

 Fifteen paratypes (three males, twelve females) complete the type 

 series; these are all in the U.S. National Museum. All were taken at 

 Williams, Arizona, during July by Schwarz and Barber, and evidently 

 in the year 1901 (some bear the year of collection, but some do not, 

 and included among the latter is the holotype). The days of collection 

 are given for all and are the first (the holotype and one female para- 

 type), the 14th (one male paratype), the 16th (one male and five 

 female paratypes), the 17th (one male and four female paratypes), 

 the 18th (one female paratype), and the 28th (one female paratype). 



Schaeffer (1934, p. 462) records the species as being taken on 

 Cowania sfansburiana Tarr. 



Distribution. — In addition to the 16 types, three other individuals 

 have been examined, all from Arizona.

Cryptocephalus cribripennis Leconte, 1880, p. 200. 



Pronotum : Light red to (usually) dark reddish, light markings creamy 

 yellow to orange. Light markings as follows: in two joining, elongate, 

 oblique spots at base; entire lateral margin (distinctly narrowed 

 medially); at apical margin; markings rather sharply delimited. 

 Punctation usually not dual, smaller punctures absent to very 

 sparse, larger punctures minute to small; with a distinct, shallow 

 impression at each side.
