would reliably serve to distinguish dejectus and nigrovittatus, so I have 

 united the two. 

 Distribution. — Both specimens examined are from Texas. 



Cryptocephalus disruptus, new species 



Figures 100, 125 



General: Body 1.73 times as long as wide; dorsal surface moderately 

 shining and without pubescence, most of ventral surface with short, 

 sparse pubescence. 



Head: Dull orange, a darker spot on vertex; antennal insertions and 

 apical margin of clypeus reddish. Front roughly punctate, punctures 

 small to moderate, dense at middle. Clypeus with basal suture obsolete, 

 moderately wider apically than at base. Antennae of male about 

 two-thirds length of body, dull orange, apical half a little darker. 



Pronotum: With dark markings on a didl orange backgi'ound. 

 Markings dark reddish, not sharply dehmited, consisting of four 

 longitudinal, subparallel stripes, separated throughout, inner two 

 widest at middle, leaving a median Hght stripe, somewhat outwardly 

 arcuate; outer dark stripes broader than inner, broadest behind 

 middle, rather narrowed anteriorly; in middle at each side with a 

 small, dark red spot. Punctation dual, surface irregularly, finely 

 ^\Tinkled, smaller punctm-es larger than usual, distinct; larger punc- 

 tures small, more or less coarse. 



Elytra: Background color creamy yellow; dark markings red, 

 punctures black. Each elytron with dark markings as follows: a 

 transverse undulate postbasal band from suture to humerus; a small 

 subhumeral spot; a moderate-sized postmedian spot from suture to 

 fifth stria, lateral to postmedian spot a rather small spot centered on 

 seventh stria and touching lateral margin; two small spots near apex, 

 one centered just before apex of fourth interval, other centered before 

 apex of sixth interval. Punctures primarily confined to dark markings, 

 large and distinctly arranged in rows only on dark markings, much 

 smaller, very sparse on light areas; punctures on dark markings 

 forming seven disconnected rows, these punctures rather smaller 

 apically; outer row of punctures distinct at apex, inner row obsolete 

 at apex. 



Ventral surface: Ventral surface, legs, and pygidium duU orange 

 WTth reddish evident; prosternum, front coxae, mesosternum, mesepi- 

 meron, and first abdominal segment at base with duU yellow, each 

 femur ventrally before apex with a yellowish spot. Fifth abdominal 

 segment of male at center feebly depressed. Anterior margin of 

 prosternum in male evenly arcuate, not produced. 



Length: 4.25 mm.
