Allotype ? , topotypic. 



Although the two sexes are so different in their coloration, 

 there are characters which determine their association. Such 

 are the venation, yellow bases of palpi and the form of the 

 antennae, as well as the similarity of the data regarding their 

 habitat. 



Pseudogeron marginalis sp. nov. 



9, Similar to P. formosa but the head entirely black; mesonotal 

 markings obsolete or faintly discernible. The second submarginal cell 

 three times as long as broad. Legs entirely, or all femora, fore and 

 middle tibiae entirely, and bases of their tarsi, bases of hind tibiae, yel- 

 low. Length, 1.3-2.0 mm. 



Holotype 9 , Alamogordo, New Mexico, May 2, 1902. 

 Type No. 6086. 



Paratypes 4 9 , topotypic, April 26 to May i, 1902. 



Pseudogeron fasciola. 



1892. Geron fasciola Coquillett, Can. Ent., xxiv, 125. 



Described from both sexes from Merced County, California. 



I have examined cotypes of both sexes. The species ap- 

 proaches the preceding but differs in the structure of the an- 

 tennae. This is the only species I have seen in which the third 

 antennal joint is at all tapering from the base to apex. The 

 decided notch and truncate apex decide its generic position.

 mology is conducting relating to the screw-worm fly, Chrysomyia nia- 

 cellaria,.the undersigned desires to secure records of the first appear- 

 ance in spring of adults of this species in various parts of the United 

 States. F. C. BISHOPP, Box 208, Dallas, Texas. 



The Cotton Worm Moth in Minnesota (Lep.). 



Apropos of the note in the NEWS for April, page 185, the cotton 

 worm moth, .llnbaitia ari/illacca, was present here in the latitude of St. 

 Paul in large numbers, last autumn, and caused a little damage and 

 much anxiety to growers of late-bearing' strawberries, because tha 

 moths actually attacked the fruit itself, inserting their proboscids into 

 the pulp, and in the estimation of the growers, seriously injuring the 

 berries. This is the first occurrence, to the best of my knowledge, in 

 the last thirteen years, of this moth being found in this latitude in 

 Minnesota. F. L. WASHBURN, State Entomologist.
