Wings slightly infuscated, first and second basal cells hyaline; anterior 

 cross-vein very oblique, joining discal cell noticeably beyond the 

 middle; first abdominal segment opaque, its anterior angles aeneous 



pulcher Will. 



3. Abdomen bright metallic green, meso-pleurae with black hairs inter- 



mixed with the yellow pile; hind tibiae of female nearly as thick as 



hind femora opacus n. sp. 



Abdomen shining bronze; meso-pleurae with only yellow pile; hind 

 femora of female noticeably thicker than tibiae aldrichi n. sp. 



4. Legs almost entirely yellow, sometimes a reddish brown and on fe- 



mora; only the tips of tarsi blackish; anterior cross-vein joins discal 



cell at middle sorosis Will. 



All the femora blackish, yellowish at tips and bases; cross-vein joins 

 discal cell a short distance beyond middle crawfordi n. sp. 



Caliprobola pulcher Will. 1 



Head distinctly broader than high. Frons in male yellow, with mi- 

 croscopic pubescence which is longer along the eyes. Arista dark, more 

 than twice the length of antennae, and with minute pubescence along 

 entire length. Frons in female black with yellowish, pollinose sides and 

 short fuscous pile. Wings hyaline, darkened somewhat along veins. 

 Length: Male 14-17 mm., wing 11-13 mm.; female 13 mm., wing 11 mm. 



Five males and two females: "Washington Territory" (type 

 specimen) ; Mt. Hood, Ore., d" and 9 . The following is material 

 loaned by Mr. Banks: Marys Peak, Ore., July 18, 1914 (L. G. 

 Centner), Pamelia, about 3000 ft, alt., Mt. Jefferson, July 27, 

 1907, and Mt. Jefferson, July 15, 1907 (J. C. BridwcU Coll.) : 

 Corvallis, Ore., Sept. 20, 1914 (A. F. Barss Coll.). This last 

 specimen is the female which unlike the others of this sex has a 

 narrow, interrupted opaque band on the fourth abdominal seg- 

 ment. The band on this segment is characteristic of the females 

 of sorosis and its ally crawford: but not of pulcher and its allies, 

 aldrichi and opacus. The antennae are missing in this specimen 

 but it agrees otherwise with C. pulcher female. 



Caliprobola opacus, new species. 



Rather slender, with head but little broader than high; dorsurn of thorax 

 entirely subopaque black; abdomen bright metallic green with several 

 opaque cross-bands; wings strongly infuscated anteriorly. 



Male: Frons reddish brown, silvery pollinose along sides; no pile. 

 Antennae reddish yellow; third joint broader than long, darkens I an- 

 teriorly; arista brownish, less than twice the length of antennae. Ocellar 

 triangle black and with blackish pile. Pile of thorax deep brown, yellow
