labeling of our specimens. The question is, however, if it is necessary or 

 of much practical use to label specimens in this manner, as students of 

 entomology who have had any experience in collecting generally know 

 whether a certain species of insect or group of insects is found in a wet 

 or a dry place. He knows but little who would look for Cicindelidae or 

 the larvae of any of our Rhopalocera in a mill-pond, or for Dytiscidte or 

 the larvae of any of our Odonata in a dry pine woods. However, no one 

 will find fault with the specimens from Mr. Lutz bearing the " Lutz 

 Label," providing the specimens are in good condition and are accom- 

 panied with exact locality and date of capture, and if collector's name is 

 given it will do no harm. All collectors of natural-history specimens 

 have a reputation, some better than others — the Ornithologist and the 

 Oologist found this out long ago. There are, no doubt, many insects 

 that it would be wise to mark in the manner Mr. Lutz speaks of, but to 

 label all our captures in this way would be a waste of precious time.

FENARIA SEVORSA AND EUSEMIA SABULOSA. 



BY HARRISON G. DYAR, WASHINGTON, D. C. 



I was in error in referring these species as synonyms in 1894. The 

 latter now stands as Tucrta sabu/osa, Boisd., in Hampson's Cat. Lep. 

 Phal., and is credited to New Mexico and California, besides other more 

 southern localities. Very possibly the species may occur within the 

 limits of the United States, but I have no specimens from our territory, 

 all being from Mexico. Fenaria sevorsa, Grote, is, however, not the same 

 insect, and the name must be restored from the synonymy, ft has been 

 subsequently described and well figured in the Biologia Centrali-Americana 

 as Diamuna aedessa, Druce. This position, in the Noctuida*, is undoubt- 

 edly correct, as the antennae are shortly pectinated, without any trace of 

 enlargement. The genus Diamuna is an Agaristid, and Druce's species is 

 therefore improperly referred to it. The genus Fenaria, Grote, must be 

 substituted for Diamuna, Druce (nee Walker). Dr. Barnes has taken the 

 species in the Huachuca Mts., and Mr. Hubbard in the Chiricahua Mts., 

 Arizona. Dr. Barnes has also from Arizona Diamuna longipes, Druce, so 

 thai the genus is thus represented in our fauna : 



Genus Fenaria, Grote. 



sevorsa, Grote. Ariz., Mex. 



aedessa, Druce. 



longipes, Druce. Ariz., Mex.
