Pegomyiasp.? 



There is a female in rather poor condition in the collection 

 which closely resembles the preceding species. It agrees with 

 minuta in color. The cruciate frontal bristles are absent, the 

 tibial bristles are stronger, there is one on antero-dorsal surface 

 of mid tibia and two on antero-dorsal surface of hind tibia. 



Locality; Milbrae, San Mateo County, California, March 20, 

 1908. 



Pegomyia bicolor Wied 



1817. Anthomyia bicolor Wiedemann, Zool. Mag., i, 77. 



Three females of this European species from California; two, 

 Berkeley Hills, Alameda County, California, April 20, 1908; one, 

 Redwood Canon, Marin County, May 17, 1908. 



The larvae feed in leaves of dock. The species has previously 

 been reported from North America. 



HAMMOMYIA R.-D. 



There are several species of this genus in North America, only 

 one of which is in this collection. 



Hammomyia maculata Stein 



1897. Hammomyia maculata Stein, Berl. Ent. Zeit., xlii, 228. 



This species appears to be western in its distribution. I have 

 seen it from Montana and Idaho. There are two specimens 

 before me as follows: one male, Beulah, New Mexico, August 17 

 (H. Skinner), and one female, Cloudcroft, New ]\Iexico, ]May 24, 

 1902. 



EREMOMYIA Stein 



This genus is represented by two species in this collection. 



Eremomyia apicalis Stein 



1897. Ercmomijin npicalis Stein, Berl. Ent. Zeit., xlii, 227. 



The female of this species has not been described. 



Compared with the male type, which is now before me, it differs 

 in being much larger, ten millimeters in length, and more robust, 

 the eyes are separated at vertex by a little more than one-tliird 

 the head-width, the third antennal joint is slightly ])roatler than 

 the parafacial in profile, the palpi are slightly broadened and 

 extend almost to apex of proboscis, the abdomen lacks the dor,>^al 

 stripe, and the last section of fourth v(nn is as long as preceding 

 section.
