A REVISION OF THE DELTOID MOTHS — SMITH. 13 



their dark colors. The Ilerniiniiiii are more fre(iueiit in open wood 

 lauds where there is considerable undergrowth, aud among the short 

 herbage I have started up Zidiclof/itafha, Chijtolita, Uormisii^ and Fhil 

 ometva. The species are not rare, but they rub very readily and are 

 not favorites with collectors. 



Few of the larva' of our species are known. According to Mr. IhMiry 

 Edwards' catalogue of described early stages there are eight species 

 only, and of these at least two are somewhat doubtfully known. Yet 

 in this series larval chara(;ters may aid in fixing the rank that should 

 be given the Ilj'penini and Herminimi. So far as my knowledge 

 extends all the former are semiloopers, lacking one pair of abdominal 

 legs, while all of the latter have the abdomiinil legs complete. The 

 lleluni are yet uncertain, but have, i)robably, sixteen feet. 



The nisects are not well represented in most collections, either in 

 number or iu character. Most of them rub so readily that they are 

 thrown away before spreading it collected with other material in a 

 bottle, and after one or two experiences of this kind the collector does 

 not take them at all. For my studies I used as a basis the collection 

 of the United States National Museum, through the courtesy of the 

 Museum otticials. This collection is unusually rich m Deltoids, because 

 for a time I made special efforts to obtain material for study and col 

 lected considerable for my i^ersonal collection, now in tlic Museum. 

 At New Brunswick the collection is a very fair one in some directions, 

 and this attbrded most of the material for dissections and for the 

 mounts from which drawings were made. 



From J)r. J. A. Lintner 1 have received a large series of specimens in 

 good condition, giving excellent opi)ortunity for the study of variations. 



Mr. G. C. Davis kindly sent me all the Deltoids of the Tepper col- 

 lection, and also those of the ^Michigan Agricultural College, containing 

 very good material. 



Prof. J. H. Comstock sent me a box of specimens taken at Ithaca, 

 which illustrated the character of the local fauna. 



From Mr. Neumoegen's collection I had a number of types of species 

 described by IMr. Grote, while all the types from the iVmerican Ento- 

 mological Society have been m my hands for study and comparison. 



Several other friends and correspondents have sent me such speci 

 mens as I needed and asked for, so I have had before me all save two 

 of the described si)e('ies, and with those I am autoptically ac(iuainted. 

 As all of Walker's names have now been applied, the ])resent classi 

 fication of the American Deltoids Tiiay be fairly considered as well 

 grounded.
