Notes on the CRAMBIDiE. 



By Prof. C. H. Ferxald.

I have recently been making a critical study of the described species 

 of North American Crmnbidce preparatory to describing the unnamed 

 species in my collection, and take this occasion to put some of the re- 

 sults on record. 



In 1813, Germar began the publication of his "Magazin der Ento- 

 mologie" which closed at the end of the fourth volume. In the second 

 volume, published in 18 17, Dr. Zincken began his Monograph of the 

 genus Chilo, which included not only the species now placed under that 

 genus, but also those under CraTiibus, Prionopteryx, Ancylolomia and 

 Schcenobius. 



Germar's genus Chilo has been broken up by later writers, but the 

 first species under it — phragtniteUus — has been retained and regarded as 

 the type of Chilo. 



In the third volume, page 114 (1818), Zincken described a species 

 under the name of Chilo Leachellus, but stated that the habitat was un- 

 known. Zeller, who saw this type, found it to be identical with speci- 

 mens in his collection from North America, and sent a specimen under 

 this name to the Cambridge Museum with which I compared mine several 

 years ago, and which I now find to agree perfectly with the original de- 

 scription. Zeller believed the species to be the same as Crambus involu- 

 tellus, Clem., but in this he was mistaken, for I have studied the type of 

 Clemens' species very critically and found it quite distinct from that of 

 Zincken. 



In the fourth volume of Germar's Magazine, published in 182 1. 

 Zincken published a Supplement to his INIonograph of the genus Chilo in 

 which he described seven North American species, viz : — sordidelhis, 

 sairapellus, prcBfcctellus, decorellus, Plejadellus, tetter ellus and incertelliis, 

 all of which I have been able to determine in my collection. 



A carefully study of the literature and types gives the following syn- 

 onomy of some of the species : 



• Chilo decorellus, Zincken, Germ. Mag., IV, p. 25c (1821). 



Crambus polyactinellics, Kollar in lit. (Zeller, Chil. etCramb.), p. 25, 

 (1863). 



Crambus goodellimius, Grote, Can. Ent. , XII, p, 17 (1880). 



Crambus bonusculalis, Hulst, Tr. Am. Ent. Soc. , XII, p. 167 

 (1886). 



This species belongs to the genus Crajnbus as restricted by recent 

 authors, and should be known by the name of Crambus decorellus.
