This bee collects pollen from the flowers of Petalostetnuin vii/osuvi 

 ( Lei^uminosce). There are two western species, P. perpallida Ckll., and 

 P. 7vootonce Ckll., which are evidently extremely close to P. citrine/la, but 

 which collect polleti from different plants. The three seem to be very un- 

 stable in their colour characters, they have probably originated from the 

 same ancestral form within comparatively recent times, and the fact that 

 they visit different flowers in the regions where they have been observed, 

 so far, does not exclude the possibility of their belonging to one species 

 only. Halictoides NovcR-angH<£ for example obtains pollen at Waldoboro, 

 Maine, from the flowers of PoiiteJeria cordata only, as reported by Mr. 

 John H. Lovell (Psyche XIII, p. 112), at Milwaukee and at Cedar Lake, 

 Washington Co., Wis. (about 30 miles north-west of Milwaukee). I have 

 never seen it collecting pollen from the flowers of any other plant but 

 Monarda fistulosa, and in Burnett Co. in the north-western part of 

 Wisconsin I repeatedly saw it visiting the flowers oi Agastache fxniadum 

 for the same purpose.

A CORRECTION. 



In the January number of the Canadian Entomologist, p. 8, the 

 late Mr. G. W. Kirkaldy corrected some preoccupied generic names in 

 insects. Among these he proposed Americides for Dryope Ch., the latter 

 name being preoccupied in Diptera and Crustacea. However, Mr. Karl 

 R. Coolidge had already proposed Dryoperia for Dryope Chamb. See 

 Entomological News, Vol. XX, p. 112. — W. G. Dietz. 



Esperanto, the international language, if it has not done so before, 

 has at last invaded the entomological field. Mr. Tor Helliesen, of the 

 Museum in Stavanger, Norway, has just published a list of Coleoptera 

 new to that country, and has added a resume in Esperanto. — H. S. 

 Saunders.
