CRYPTOCEPHALUS IN AMERICA NORTII OF MEXICO 37 



four female paratypes were taken at Winterhaven, California, on 

 June 25, 1952, by D. J. and J. N. Knull; the allotype and six of the 

 paratypes are in the Ohio State University collection. Male and female 

 paratypes are in the USNM collection. 



Discussion. — The species is separable from its nearest relative 

 duryi by the development of the pronotal stripes and the elytral 

 punctures. In duryi, the pronotal stripes are sharply dehmited and 

 complete; in binotatus, they are irregular and less sharply delimited to 

 incomplete, much reduced, or even absent. The elytral punctures of 

 duryi are quite large, confused, and have only faintly evident (or no) 

 traces of alignment into rows. There is a tendency toward lateral 

 interconnection of the discal punctures by reddish pigment. The elytral 

 punctures of binotatus are smaller, distinctly aligned into rows at least 

 apically, sometimes also basally (and even throughout in some males), 

 and the punctures are infrequently interconnected by pigment. This 

 species is named for the type which has two dark pronotal spots.

 Cryptocephalus bispinus SufiFrian, 1858, p. 347. 



Pronotum: Red to orange with lighter basal obhque spots (some- 

 times vague), lateral and apical margin orange or yellow, lighter areas 

 usually not sharply delimited, rarely almost entirely red with lateral 

 and apical margins yellowish; punctation dual, larger punctures minute 

 to small. 



Elytra: Each elytron creamy yellow to orange with two dark 

 orange to red or even black vittae as follows: from base of second, 

 third, and fourth intervals to apex of first interval, always complete 

 (rarely with scutellar and first interval also dark); from humerus to 

 apex of fourth, fifth, and sixth intervals, nearly always complete, 

 rarely interrupted once. With eight rows of punctures, sixth and 

 seventh rows confused, punctures small, dense, much finer apically; 

 inner and outer rows distinct at apex, usually clearly meeting. 



Prosternum: Anterior margin evenly arcuate in both sexes. 



Length: 4.0 to 6.7 mm. 



Discussion. — The species has been previously reported only from 

 Florida. During this work, I encountered individuals from Georgia, 

 Alabama, and Texas. The 14 southeastern specimens are all females 

 and range in length from 5.6 to 6.7 mm. The 21 Texas specimens con- 

 sist of 10 females and 11 males; the females range in length from 5.4 to 

 6.2 mm., and the males from 4.0 to 4.9 mm. AU the Texas specimens 

 are from the eastern part of the state. I have found no significant 

 differences between the southeastern and Texas females of this species,
