The Bee-genus Xenoglossa in California. 



By T. D. a. Cockerell. 

 In Canadian Entomologist, August, 1896, is described the 

 finding of three species of Xenoglossa in the flowers of Cucur- 

 bita in New Mexico. Since that time, wherever I have found 

 Cucurbita I have also found at least one species of Xenoglossa. 

 Therefore, when I observed quantities of Oicurbita fo3tidissima 

 in the city of Los Angeles last July, I lost no time in looking 

 for Xenoglossa, and was duly rewarded by the capture of two 

 species in numbers. 



(i.) Xenoglossa patricia angustior, Ckll., Entom., March, 1900, p. 64. 

 Described from one example taken at Buckeye, Arizonia. 



Five taken at Los Angeles, California, in flowers of Cueur- 

 bitafoetidisshna, July 22, 1901. 



(2.) Xenoglossa angelica, n. sp. — cf, $, about 13 mm. long. Similar 

 to tile eastern X. priiinosa Say, but conspicuously differing in the velvety 

 pubescence of the abdomen, which is orange-golden instead of silvery- 

 white, especially bright and beautiful in the 9. covering the apical half. 

 Structurally, the insects agree in all essential particulars, and one would 

 not regard them as distinct species, were it not that the color-diflTerence 

 is conspicuous and perfectly consistent in long series of each, and they 

 inhabit entirely different regions. 



Hab. — Los Angeles, California, in flowers of Cucurbita foeti- 

 dissima, Jtily 22, 3 9 , 8 S ; County Farm, Los Angeles Co., 

 at flowers of Ip07ncva, 3 S , July 15. Also a male taken by my 

 wife at San Diego, Calif., August 10, at flowers of IpomeBZ.. 



Xenoglossa ipotnoece Rob , from Illinois, seems to be hardly distinct 

 from X. priiinosa. 



Notes on Butterflies and Description of an Aberration. 



By Addison Ellsworth. 

 I see by your April, 1901, issue that Mr. Harvey Mitchell, 

 at a meeting of the Harris Club of Boston, exhibited a melanic 

 male Colias philodice from Medford, Mass. I would state that 

 I have a melanic male of Colias philodice taken in the city of 

 Binghamton, N. Y., Aug. 12, 1898. It is almost coal black, 

 so dark in fact that the usual border is only discernable by its 

 lighter shade.
