CONTRIBUTIONS TO A KNOWLEDGE OF THE 

 CRAMBINiE OF NORTH AMERICA. I.* 



Geo. G. Ainslie, 

 Entomological Assistant, U. S. Bureau of Entomology. 



Since undertaking a study of the Pyralid subfamily Cram- 

 binae it has been found that the Httle that has been pubHshed 

 concerning it is so widely scattered and so fragmentary that it 

 is very difficult of access. In the present series of papers the 

 writer proposes to bring together all the available information 

 concernmg each species, both that previously published and 

 that which has resulted from his own work. Both systematic 

 and biological data will be included when available but the 

 papers cannot be exhaustive for our knowledge of many points 

 is too scanty. They are designed to afford a convenient starting 

 pomt for further work by making it unnecessary for others to 

 go repeatedly over this same ground and to put within reach of 

 economic workers the available facts which may be useful in 

 economic studies of these insects. The bibliographies are 

 mtended to be complete and the writer will welcome corrections 

 and additions thereto. 



Crambus hemiochrellus Zeller. 



Systematic History. Aside from descriptions of the adult 

 httle has been published concerning this species. It was 

 origmally described by Zeller (1877). Grote (1880) Hsted it 

 among the American species of the genus Crambus. It was 

 reduced to a variety of mutabilis by Smith (1891) in which 

 error he was followed by Felt (1894). Hampson (1895) placed 

 It as a synonym of luteolellus but Pernald (1896) redescribed 

 and re-established the species as valid and it so appears in 

 Dyar's (1902) catalog. 



Distribution. Zeller's specimens, all of which were sent 

 him from this country, were collected in Dallas and Bosque 

 Counties, Texas. These are the only localities appearing in the 

 published records. To them the writer can add Chattanooga, 

 Tenn., WelHngton, Kan., and Elk Point, S. D., moths having 

 been take n at the first two places by himself and at the last
