A PRELIIHIMARY REVISIOIV OF THE LiEPIDOP- 

 TEROUS FAMILY NOTODOKTIDJE. 



BY B. NEUMOEGEN AND HARRISON G. DYAR, S. B., A. M. 



The following revision is continuous with that being published by 

 us in the journal of the New York Entomological Society, including 

 the series of families formerly classed as " Bombyces." Mr. Dyar 

 has prepared the present paper from the material in Mr. Neumoegen's 

 collection, and has recently gone over a large part of the species with 

 Dr. A. S. Packard, to whom our thanks are due.* The manuscript 

 has thus become complete, and we have concluded to present this 

 family separately, thus saving space in the New York journal. 



The NotodontidiB belong to the group of specialized frenulum con- 

 serves in which the cubitus (median vein) is apparently three 

 branched. Their relations may, perhaps, be best exhibited by a 

 synopsis of groups of the Lepidoptera, which is drawn up on the 

 lines suggested by Prof. J. H. Comstock.f 



We have used two systems of nomenclature of the veins of the 

 wings, and present the following table, showing the corresponding 

 name for each vein : 



«- We would refer to Dr. Packard's monograph for a fuller treatmeDt of the 

 Notodontidse than is possible iu the limits of this paper. We deem ourselves 

 fortunate in having been able to consult with Dr. Packard concerning the syn- 

 onymy of several of the species, which is the better established by a consensus 

 of opinion. In a few instances, notably in the rank to be assigned to certain 

 local forms, we have felt obliged to differ from Dr. Packard.
