294 DIPTERA FROM SOUTHWESTERN UNITED STATES 



The male standing as polychaeta Stein in the Hough collection 

 and named as such by Stein is minuiipalpis, so that the former 

 species cannot be considered as occurring in this country until an 

 authentic specimen is obtained. 



Fannia f uscula Fallen 



1820. Musca f uscula Fallen, Dipt. Suec, Muse, 86. 



One male from Lagunitas Canon, Marin County, California, 

 March 29, 1908. 



Fannia laevis Stein 



1897. Homalomijia laens Stein, Berl. Ent. Zeit., xlii, 174. 



One female of this species in collection agrees with the type 

 female in all particulars. The species has in both sexes a single 

 bristly hind coxal posterior hair, and the lower calyptra distinctly 

 produced bej^ond the upper. 



Locality; El Paso, Texas, March 31, 1902. 



Fannia spathiophora sp. n. 



Female. — Black, shining. Head with slightl}' iridescent pruinescence, 

 that of frons when seen from in front almost pearlaceous. Thorax unstriped, 

 more distinctly pruinescent than abdomen. Legs black, bases of fore tibiae 

 pale. Wings clear, veins brown, yellow basally. Calyptra whitish yellow. 

 Halteres yellow. 



Frons slightly over one-third the head-width, orbit at widest part slightly 

 narrower than interfrontalia at that part, bristles moderately long, each 

 orbit with numerous short setulose hairs; antennae reaching almost to mouth 

 margin, third joint broad; arista with short pubescence; cheek linear; proboscis 

 short and thick; palpi short, leaf-like, at broadest part as broad as third antennal 

 joint. Acrostichals strong, four to five pairs in front of suture; lower calypter 

 smaller than upper, but of moderate size. Fore tibia unarmed at middle; mid 

 tibia with one antero-dorsal and one postero-dorsal bristle; hind femur with two 

 to three widely placed bristles on apical hatf of antero-ventral surface; hind 

 tibia with three bristles, one antero-ventral, one antero-dorsal, and one postero- 

 dorsal, the latter the strongest; hind coxae bare above on posterior margin. 

 Last section of fourth vein nearly three times as long as preceding section; 

 apical sections of veins 3 and 4 slightly convergent. Length, 3 to 3.75 mm. 



Type. — 9 ; Gold Rock, Rainy River District, Ontario, Canada, 

 July 21, 1905, (H. H. Newcomb), [Ilhnois]. Paratypes.—l 9, 

 topotypical, [Illinois]; 1 9 , Beulah, New Mexico, June 29, 1902. 



The very conspicuously dilated palpi separate this species from 

 any other known to me.
