DIAPERINI NORTH OF MEXICO — TRIPLEHORN 445 



cessfully reared on moist cornmeal and spoiled cereals (Cotton, 1941). 

 Schuster (1946) reports that it is "one of the most frequently, 

 present and abundant tertiary pests (in stored grain and cereals) in 

 New York [State]." 



The origin of this species is unknown. Champion (1895) con- 

 sidered it to be American, basing his assumption on its having been 

 originally described by Say from this country. 



Types. — None seen. Say's Diaperis hijasciata was collected at 

 "Engineer Cantonment." The first specimens of Alphitophagus 

 quadripustulatus that Stephens saw were reared on flour; later, he 

 acquired a large series from Cambridge, England. D. picta was 

 described by Men^tries from the Caucasus and Redtenbacher's populi 

 from Austria. The aberration unifasciatus Donisthorpe was collected 

 at Burwell Fen, England, and Roubal's subspecies jwcZog'Ms came from 

 Palestine.
