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

Differs from all the other species recorded from Xorth 

 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 parvula 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

 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
