One female, Fort Wrangel, Alaska, Wickham; one male, Kadiak, 

 Alaska, Kincaid (Harriman Expedition). 



Two postacrostichal bristles. Male front one-twelfth of head 

 width, female front one-third head width. Palpi yellow. Basal 

 abdominal segment blaekish. Whole body purplish, strongly violet 

 tinged, especially in the female. Tegulse of female white, of male 

 smoky. Buccae, face, and front blackish, epistoma paler. Second

Type.— Cat. No. 10,893, U. S. N. M. (Fort Wrangel, Alaska). 



LuciHa pilatei Hough. — Two males, two females, Florida, Porto 

 Rico, Guatemala, and Peru. A neotropical species. 



Two postacrostichal bristles. Male front one-eighth head width, 

 female front one-fourth head width. Palpi yellow. Abdomen as 

 in australis, only the purplish or black margins of segments often 

 more marked. Buccae of female yellow, of male gray with yellow 

 anteriorly. A second pair of ocellar bristles in female more or less 

 hair-like, but distinctly larger and thicker than the other hairs of 

 ocellar area ; in male very weak, not appreciably stronger than the 

 other ocellar hairs. 



The purplish black hind margins of second and third abdominal 

 segments are characteristic of this and one or two other species, 

 added to which is the blackish basal segment. The latter in some 

 females shows a little metallic green on sides, but the general opaque 

 black of its dorsum is the distinguishing character. Also the hind 

 margins of second and third segments are only faintly purplish in 

 some specimens, but distinct traces are present in all. The white 

 tegulae are characteristic of this species, and serve to separate the 

 males of pilatei from the males of similar species having a black 

 basal abdominal segment. 



Lucilia australis, sp. nov. 



Two females, Tennessee, Texas (Girault) ; one male, Popoff 

 Island, Alaska (Kincaid, Harriman Expedition). The male is pro- 

 visionally referred here. 



Two postacrostichal bristles. Male front one-twelfth head width, 

 female front one-fourth head width. Palpi infuscate yellow. Basal 

 abdominal segment black above, conspicuously so. the purplish or 

 darker hind margins of second and third segments also showing.
