CRYPTOCEPHALUS IN AMERICA NORTH OF MEXICO 49 



Elytra: Creamy yellow to orange, punctures and markings red to 

 dark reddish. Dark markings as follows: an elongate spot at base of 

 first interval (this often joins suture at its apex); elongate spots at 

 base, middle, and apex of third interval; a humeral spot; two spots 

 behind humerus, one obliquely above and one obliquely below hu- 

 merus; a submedian spot; a spot at apex of seventh interval; markings 

 usually consistent, sharply delimited, sometimes expanded or reduced. 

 Punctures quite large, more or less irregular, sparser than usual, 

 generally forming eight evident rows, rows often obscure; rows six and 

 seven confused and much reduced; punctures finer apically; inner and 

 outer rows distinct at apex, clearly meeting. 



Prosternum: Anterior margin in female somewhat or vaguely 

 produced into a lobe, usually pointed; anterior margin in male dis- 

 tinctly produced into a pointed lobe. 



Length: 4.8 to 6.2 mm. 



Discussion. — There is a possibility that cribripennis is synonymous 

 Avith irroratus Suffrian (1852b, p. 32). I have examined the description 

 of irroratus but have not been able to assign the name ^^-ith certainty 

 to specimens in the Central American series of the USNM collection. 

 Among specimens in this collection determined as C. irroratus, I find 

 four distinct species, one of which matches cribripennis. The other 

 three have the dark elytral markings joining to form transverse bands; 

 I think it likely that irroratus applies to one of the last three, but to 

 which one I cannot determine. 



Collection data refer to specimens as taken on orange trees, on 

 cotton, on marsh willov/, and on black-eyed peas. 



Distribution. — The 64 specimens examined are from southern 

 Texas.

 Cryptocephalus cuneatus Fall, 1932, p. 24. 



Pronotum: Creamy yeUow to very fight orange with three broad, 

 orange to (sometimes) dark red longitudinal \dttae, one median, two 

 lateral, these sometimes expanded and joining apicaUy, markings not 

 sharply defimited. Punctures dual, larger punctures minute to small. 



Elytra: Each elytron creamy yellow to very fight orange with black 

 markings, disk sometimes clouded with reddish. Suture more or less 

 broadly margined with black, a black mark from humerus to apex of 

 seventh interval. With eight rows of punctures, sLxth and sometunes 

 fifth rows confused, lateral mtervals distinctly convex, punctures as 

 large and dense as usual, punctures finer apicaUy; inner and outer 

 rows distinct at apex and clearly meeting.
