these are equally strong and the scutellum has lateral bristles besides 

 the erect apical pair. 



Femora and tibiae of male, especially of fore and hind legs, stout 

 and very strongly spinose, each spine emitted from a conical tubercle 

 at its base ; outer surfaces of middle femora with short spines ; middle 

 tibiae and tarsi, especially on flexor surfaces, thickly pilose with long 

 curved pile. Female with legs more slender, the spines limited to the 

 flexor and extensor angles and more bristle-like ; no pile on middle 

 legs. Only apical margin of fifth abdominal segment with long bris- 

 tles. Length 5-7 mm.

Differs from all the other species recorded from North 

 America by the strongly spinose legs and the long pile on the 

 middle pair. These spines are strong and straight, not curved 

 bristles as in frigida. It seems allied to parvnla Hal. in col- 

 oration. 



Tetanops carbona n. sp. 



Black, more or less shining, front as broad as, or broader than, eye, 

 opake except at vertical angles, not punctate or wrinkled ; the broad 

 median yellow stripe limited laterally by narrow lines of brown which 

 end just laterad of the antennae. Orbits broadly white, which color 

 extends down to the cheeks, the broad median carina of face of same 

 color; foveae shining and darker, translucent. Cheeks and lower oc- 

 ciput yellower, rather shining; occiput above nearly shining brown. 

 Palpi yellow, proboscis brown. Antennae tawny to brown with apex 

 darker; third joint twice length of second. 



Thorax, abdomen and legs excepting knees and articulations shining 

 black, but mesonotum more or less white pruinose. Squamae whitish ; 

 halteres tawny. Scutellum triangular, convex, with four bristles. 3 

 pair prescutellars, I postalar, 2 supraalars, 2 notopleurals, I propleural, 

 humeral, mesopleural and sternopleural each. 



Wings yellow-hyaline ; marked with brown spots as follows : a spot 

 in apex of costal cell extending faintly to vein 4, a small spo<- at 

 apex of vein i ; a larger spot in apex of marginal cell extending nearly 

 to vein 3 and along costa to apex of 4, its proximal margin about op- 

 posite post c. v. ; stigma yellow ; vein I setulose. Fore femora only
