OXYPTILUS. 31 



This species, probably more nearly allied to 0. pih> 

 sellm than to any other, and intermediate between 

 0. fenuidactylus and 0. periscelidacfylus, occurred 

 not uncommonly from July 17th to 2'jth, 1871, in 

 Shasta County, California. I was not aw^are that my 

 specimens agreed with 0. deJawaricus until I sent 

 a specimen to Prof. Zeller, wlio considers them 

 identical, although his type is a little darker. 



It is, perhaps, superfluous to publish this descrip- 

 tion ; bnt as Prof. Zeller described his species from a 

 single example, I venture to do so in case it may 

 ultimately be found that the Californian form is in 

 any way to be distinguished from that which occurs 

 in Delaware.

The specimen here figured, which Prof. Zeller 

 informs me is identical with his 0. nigrociUatus, was 

 taken with many others, which exhibited no variation 

 whatever in colour, and scarcely any in size, on the 

 14th July, 1871, in Shasta County, California, the 

 only locality in the Western States -svhere I met
