ON THE MOTHS COLLECTED BY PROF. SNOW IN NEW 



MEXICO. 



BY A. R. GROTE, PRESIDENT OF THE NEW YORK ENTOMOLOGICAL CLUB. 



The collections made by Prof. Snow, in New Mexico, have turned out to be 

 of great scientific interest. Not only have there been valuable and showy 

 insects taken, such as Hyperchiria Zephyria, Glover ia Arizonensis, Hahsidota 

 Ambigua and Aspilaies Viridirufaria, but a number of new species, interest- 

 ing from their structure, have been captured, such as Trichothosia Parallela. 

 Again, light has been thrown on the geographical distribution. We have 

 not only Californian and Eastern forms meeting as on common ground, but 

 new representative species have occurred in these remote latitudes, such as 

 Copimamestra Occidenta. The discovery in southern Arizona of Phcegarista 

 Sevorsa Grote, a species allied to the East Indian P. Transiens, is very re- 

 markable; and other just as interesting resemblances with Asiatic forms may 

 be expected from this new field for entomological exploration. It must not 

 be forgotten that my genus Heliochilus occurs only in India and the United 

 §tates. So far as the moths are concerned. Prof. Snow has been the pioneer, 

 and a worthier one ould not be found. 



The late Professor Agassiz, whose lectures were so charming from his learn- 

 ing, noble presence, and enthusiasm for natural history, held strongly for the 

 distinctness of what are called " representative species." In the Moths, the 

 near resemblance of some species, such as Copimamestra Occidenta and Apa- 

 tela Occidentalis, with their European analogues, I have accounted for by the 

 theory that they are descendants from a single member of a Tertiary circum- 

 polj^r fauna. There is a parallel between vertical ascension and distribution 

 towards the Pole, as Professor Agassiz has explained. This is shown by a 

 comparison of the faunse of Mount Washington and Labrador. I think I 

 was the first to identify the Arctic Laria Rossii, from specimens taken by Mr. 

 B. Pickman Mann on Mount Washington. I have also identified the Agrotis 

 Scropulana and A. Opipara, of Mr. Morrison, described from Mount Wash- 

 ington, with the Pachnobia Carnea and Agrotis Islandica of Mr. Moeschler, 

 from Labrador. After seeing Icelandic specimens, however, I doubt if the 

 Labrador species is the same. Dr. Packard's " Islandica " from the West is
