AET. 2 NEW UNDESCEIBED CEAlirE PLIES ALEXANDER 7 



with the unusually long knobs dark brown, the base of the stem nar- 

 rowly paler. Legs with the coxae and trochanters obscure yellow; 

 femora brown, paler basally, the color deepening outwardly, the tips 

 narrowly but conspicuously light yellow ; tibiae and tarsi dark brown. 

 Wings with a strong brownish tinge, the stigma oval, darker brown ; 

 a paler spot before and beyond the stigma ; veins darker brown, the 

 obliterative areas at end of Es and across cell ^rst M^ conspicuous; 

 vein ^4+5 dark and equally developed throughout its length. Vena- 

 tion: /S'Ci, ending about opposite one-third to one-fourth the length of 

 Es, Sg^ at its tip ; Es gently arcuated ; basal section of E^+^ strongly 

 arcuated; cell first Mo, relatively wide, only about one-half longer 

 than wide; iri-cu at the fork of M. 



Abdominal tergites dark brown, the basal sternites obscure brown- 

 ish yellow, the bases of the segments darker; segments eight and 

 nine abruptly paler yellow; remainder of hypopygium dark. Male 

 hypopygium (fig. 4) with the ninth tergite {t) gently emarginate 

 posteriorly, the lateral portions provided with a few very long setae. 

 Basistyle (6) relatively elongate, the mesal lobe large, densely setif- 

 erous. Dorsal dististyle a powerful, nearly straight, chitinized rod, 

 at the apex with a blackened flattened plate that terminates in a 

 comb of about nine blunt teeth. Ventral dististyle {d) small, fleshy, 

 densely setiferous, the rostral prolongation a long, sinuous rod, at 

 near midlength bearing two long black spines from elongate swollen 

 papillae. Gonapophyses {g) with the mesal apical angle greatly 

 produced into a long flattened blade, the apex very shallowly bifid. 



Habitat. — Oregon. Holotype, Marshfield (J. M. Aldrich). 



Type.— Male. Cat. No. 40322, U.S.N.M. 



The present species appears to be closely allied to L. adjecta 

 (Doane), but I can not reconcile the descriptions of the two. The 

 present species has the anterior vertex silvery, the praescutum with 

 a broad median stripe and the wings strongly infumed, with pale 

 areas before and beyond the stigma. Vein E^ does not behave at all 

 as described and figured by Doane for adjecta, but bends at a right 

 angle into the costa, immediately opposite E^. The very elongate 

 last segment of the antenna, the long flagellar verticils, the conspicu- 

 ous yellow terminal ring of the femora and the very peculiar struc- 

 ture of the hypopygium are all noteworthy features of the present 

 species. 



mCRANOMYIA PENICILLATA, new species 



Related to D. haeretica Osten Sacken, from which it is distin- 

 guished especially by the structure of the male hypopygium ; dorsal 

 dististyle slender, sickle shaped; base of ventral dististyle on inner 

 face with a low lobe bearing two conspicuous pencils of long yellow 

 setae. 



Male. — Length about 6.2 mm. ; wing, 6.8 mm.
