56 U.S. NATIONAL IVIUSEUM BULLETIN 290 



Discussion. — This species is similar to but evidently distinct from 

 a single specimen from the Monros collection determined as C. austerus 

 Suffrian taken at Orizaba, Mexico. In the latter individual, the elytral 

 surface is rather depressed by two narrow, transverse, dark bands, 

 and the striae are somewhat distorted. This condition does not occur 

 in fulguratus. Two additional specimens in the USNM collection (one 

 from Mexico, the other from Guatemala) determined as C. rimosus 

 Suffrian differ hoTn. fulguratus by the above characters and apparently 

 are not distinguishable from austerus. 



A single individual is recorded from oak. 



Two of the specimens on hand (both from Sabinal, Texas) are 

 uniformly light orange above with very faint indications of the dark 

 elytral markings. These markings are more or less distinct in aU the 

 other specimens. 



Distribution. — The 130 specimens examined are from Texas, 

 Arkansas, and Kansas. 



Cryptocephalus gibbicollis gibbicollis Haldeman 



Figure 79 



Cryptocephalus gibbicollis Haldeman, 1849, p. 252. 



Pronotum: Orange to red, nearly always with two vague oblique, 

 yellowish spots at base; lateral and apical margins more or less 

 yellowish; yellowish markings often reduced or expanded. Surface 

 with dual punctation, larger punctures minute to small. Pronotum in 

 profile rather to distinctly more gibbous than usual. 



Elytra: Creamy yellow to very light orange with black markings. 

 Each elytron with two complete, sharply deUmited, black (rarely 

 very dark reddish) vittae as follows: from base of second, third, and 

 fourth intervals to apex of second interval; from humerus to apex of 

 seventh to fourth intervals. With eight rows of punctures, usually 

 sixth and seventh rows confused, sometimes only sixth, fifth row often 

 abbreviated; punctures as usual in size and density, finer apically; 

 inner and outer rows usually clearly meeting at apex; epipleuron 

 black throughout. 



Prosternum: Anterior margin in both sexes somewhat produced 

 into a broad lobe. 



Length: 5.2 to 7.1 mm. 



Discussion. — Three individuals from Ashland, Massachusetts, 

 have the vittae much narrowed but still complete; they are thus 

 nearly intermediate between g. gibbicollis and g. decrescens. 



Label data provide the record "on Kalmia angustijolia." 



Distribution. — The 91 specimens on hand are from Maine, New 

 Hampshire, Rhode Island, Connecticut, Massachusetts, New York,
