CONTRIBUTIONS TO A KNOWLEDGE OF THE 

 CRAMBINAE. II. 



Crambus laqueatellus Clemens. 



By Geo. G. Ainslie, 

 U. S. Bureau of Entomology. 



Crambus laqueatellus is one of the largest and most beautifully 

 marked species in this genus and is easily distinguished from all 

 other North American forms by the two parallel silver stripes 

 running almost the full length of the fore wing. (Fig. II, 6). 



SYSTEMATIC HISTORY. 



Crambus laqueatellus was first described by Clemens in 

 1860. Walker redescribed it in 1863 from specimens from 

 "North America" as C. semifusellus, a name reduced to 

 synonomy in 1891 by Smith. Aside from its inclusion in 

 various lists and the few references to it as an economic species 

 its literature is meager. Fernald (1896) and Holland (1903) 

 both figure the moth in colors. Nothing has ever been written 

 about any stages other than the adult, except Felt's (1894) 

 description of the egg and first stage larva. In other respects 

 also his notes are hitherto the most extensive of any relating 

 to this species. 



DISTRIBUTION. 



It is a North American species and occurs throughout a 

 section of the United States extending from Maine to Texas 

 and from Louisiana and Tennessee on the south to Colorado 

 and southern Minnesota on the north. The writer has seen 

 specimens from nearly every state within this area. The 

 Texas record is based on ZeUer (1872) who received specimens, 

 presumably from Bosque County, collected by Boll. Fyles 

 (1896) records it from Montreal and Quebec, Zeller (1863), 

 Lintner (1874) and Felt (1894) Hst it from New York State, 

 and Fernald (1896) from Maine and Louisiana. As indicated 

 by Fyles' records, the species extends somewhat into Canada, 

 but it does not appear in Allen's (1918) list of Nova Scotian
