Tetanocera soror new species. 



Length, (i to 9 mm. Very close to T. vicina Macq., the general size 

 of about seven millimeters being sHghtly smaller. Ochraceous, inter- 

 frontal stripe parallel-sided, bordered with brown, cervical and antennal 

 orbital spots black; second antennal joint shorter than the acute third, 

 arista very densely bushy. Thorax heavily polHnose, vittae distinct, 

 about four rows of setul^e on middle stripe. Abdomen subshining, 

 hypopygium moderately small, paramera short, bluntly rounded 

 triangular, not setulose, foramen large. Tarsi apically dark, front 

 femora with six setae above, middle femora with one anterior bristle at 

 middle and none behind, hind femora with three dorsal and a double 

 full series of ventral bristles and flexor setulse. Wings lutescent basally, 

 outer costal and apical portions infumated, crossveins bordered with 

 black, posterior crossvein lightly sinuous. 



Type: Mica, Washington,* 14 July, 1918. Thirteen para- 

 types, Pullman and Mount Constitution, Washington;* Avon, 

 Idaho;* Beaver Creek, Montana,* (Hunter). 



Tetanocera obtusifibula new species. 



Length, 8 to 11 mm. Closely resembling T. vicina, the males 

 easily recognizable by the centrally constricted tubular paramera of the 

 hypopygium. Cervical spot dark brown bounded by yellow; inter- 

 frontal stripe reaching to or beyond the middle of the luteous sutural 

 band, laterally bounded with brown; orbital spot at antennae black, 

 merging into golden at the eye; face and cheeks golden sericeous; outer 

 side of second antennal joint one-fourth longer than deep, third joint 

 triangular, with rounded excision above and apically rather pointed; 

 arista very bushy plumose, with stout base. Thorax with complete 

 median pair of rusty brown vittce and with two interrupted lateral 

 stripes, making six vittas between the wings. Abdomen uniformly 

 ferruginous yellow, paramera of hypopygium not pollinose, relatively
