136 ENTOMOLOGICAL NEWS. [June, 



were captured from beneath the bark of logs; one small brown 

 butterfly, a Chionobus ?, whose range was between 9500 and 

 13,000 feet, and one species of locust, a Pezotettix, which was 

 there quite abundant, and a single specimen of which was after- 

 ward taken near the 14,000 feet level. 



At the latter point, which was near the lower limit of snow and 

 as high as I ascended two species of rough-backed beetles be- 

 longing to the genus Phellopsis f ; one species of Phalangidae, or 

 harvestmen; the Pezotettix mentioned above, and three species 

 of small-sized myriopods were found during several hour's search, 

 the beetles and myriopods being quite common beneath the bark 

 of logs and beneath rocks. A few half-grown specimens of a 

 Centhophilus, a genus of wingless Locustida, were also secured. 

 These were evidently the bulk of the species of insects found at 

 that altitude at that season of the year, though Dr. Scoville saw 

 at the top of the mountain, 18,000 feet, two specimens of a small 

 white butterfly, but was unable to capture either of them.

On the Species of ONCOCNEMIS in Colorado. 



By DAVID BRUCE. 



As the Noctuid genus Oncocnemis Lederer is not very abun- 

 dantly represented in the majority of our collections, perhaps a 

 few observations on the species I have taken in Colorado may be 

 acceptable. 



1. O. Haycsii Grt. Not very rare at light and over flowers 

 at night in central Colorado, August and September. I took 

 two examples in July this year in western Colorado flying round 

 flowers by day. 



2. O. Dayi Grt. Abundant, flying over flowers by day in 

 South Park at 10,000 feet elevation; it has all the habits of Plusia 

 Snowi and P. Hochenwarthi, and can scarcely be distinguished 

 from these species until captured. I have seen it no place but 

 at the locality named, August and September. 



3. O. fasciatus Smith. One beautiful example flying over 

 flowers by day August 2oth, southwest Colorado. 



4. O. tenitifascia Smith. Common just at timber line in South 

 Park, flying with Dayi over flowers in bright sunshine; looks 

 extremely like a Botis when flying, August and September.
