in /. leucomelas. The siibspecific iiajiie refers to the three distinct 

 markings of each elytron. 



Cryptocephalus leucomelas vitticollis Leconte 



Figure 59 

 Cryptocephalus leucomelas vilticollis Leconte, ISSO, p. 200. 



Pronotiim: Creamy yellow to light orange with four orange to red, 

 longitudinal, usually sharply delimited vittae from base to apex, 

 lateral two on each side often narrowly to broadly joined ai)ically. 

 Surface with dual punctation, small punctures sparse, larger punctures 

 small to moderate; surface sometimes scabrous and with larger 

 punctures obscured and small ones absent. Profile more declivous 

 than usual. 



Elytra: Creamy yellow to light orange, dark markings orange to 

 red and predominating in extent over yellow or orange. Each elytron 

 with basic pattern as in I. leucomelas but much expanded, leaving 

 yellow as follows: in a narrow basal strip, in a transverse median 

 band (not attaining suture), in a narrow transverse, anteapical spot, 

 and in an apical spot. Striae and punctures as in /. leucomelas. 



Prosteruum: As in I. leucomelas. 



Length: 4.2 to 5.0 mm. 



Distribution. — Only nine specimens are in the U.S. National 

 Museum, all from Colorado. 



Cryptoceplialus lunatus, new species 



Figures 106, 128 



General: Body 1.8 times as long as wide; dorsal surface shiny, with 

 short, fine, whitish pubescence; most of ventral surface with fine, 

 fairly dense, whitish pubescence. 



Head: Black; front with fairly dense punctures except on vertex, 

 the latter usually somewhat produced; clypeus finely punctate, not 

 sharply delimited, broadest apically. Antennae a httle longer than 

 body in male or about tliree-fourths length of body in female, dark 

 brown to nearly black. 



Pronotum: Black throughout; in lateral view rather gibbous; 

 punctation dual, smaller punctures minute and moderate in density, 

 lai-ger punctures moderate in size, rather coarse. 



Elytra: Black, at base narrowly reddish-orange; light markhig of 

 each elytron hi lateral view nearly crescent-shaped, extending from 

 suture (or near suture) to side of elytron and posteriorly at side to 

 middle of elytron; sometimes (two of fom- specimens) apex of each 

 elytron with small reddish-orange spot. Each elytron with nine rows 

 of fine punctures, striae not or very feebly impressed; all rows fairly
