genus Fogonomyia, the surface largely hairy (fig. 4), Thorax with four pairs 

 of presutural acrostichals, and four pairs of postsutural dorsocentrals; sterno- 

 I)leurals 1 : 2. Abdomen elongate ovate; basal sternite bare; fifth sternite 

 slightly emarginate at apex. Fore tibia with one or two weak median posterior 

 bristles; fore tarsus stout, not longer than tibia, with sensory hairs as in 

 Phaonia errans Meigen; mid femur with fine hairs on ventral surfaces; hind 

 femur with a series of long bristles on anteroventral surface; hind tibia with 

 a series of rather closely placed bristles on anteroventral surface, the antero- 

 dorsal surface with some outstanding setulae but no strong bristles, calcar 

 long, and basad of it some erect setulae, the apex with three straight, strong, 

 blunt-tipped spines on ventral surface, which are of the same length and 

 longer than in allied species. 



Female. — ^Frons over one-third of the head-width; each orbit with the 

 anterior and sometimes the next .supra-orbital bristle directed forward; cru- 

 ciate bristles present but weak. Sternopleurals 1:3 or 1:4. Genitalia 

 without thorns. Fore tibia with two or three anterodorsal bristles; mid 

 femur with some bristles on basal half of anteroventral and posteroventral 

 •surfaces; mid tibia with but one posteroventral bristle; hind tibia with two or 

 three anterodorsal and four or five anteroventral bristles. 



Length, 8 to 9 mm. 



Originally described from Craig's Mountain, Idaho. I have 

 the type male before me now. I also have before me a male 

 from Sherborn, Massachusetts, May 12, and a female from King 

 and Bartlett Lake, JVIaine, August, 1895, sent to me by Mr. C. W. 

 Johnson. 

 Pseudophaonia griseocaerulea new species 



Male. — Similar in color to orichalcea, differing in having the fourth ab- 

 dominal tergite colored as are the others, and the cal}i)trae and their fringes 

 yellow. 



In addition to the characters listed in the synopsis for separating it from 

 the preceding species I may enumerate the following: the orbits are less 

 strongly bristled, only one weak upper orbital is directed backward (fig. 5), 

 and the orbital hairs are in line with the bristles instead of mesad of them; 

 the basal abdominal sternite is hairy; the hind tibia has fewer and longer 

 anteroventral bristles, the anterodorsal setulae are stronger and one at least 

 assumes the proportions of a bristle, the posterior and posteroventral surfaces 

 are furnished with long hairs, and the ai)ical ventral bristles are not of uniform 

 length and strength, only one being really long. 



Length, 8.2.5 mm. 



Tj'-pe locality illegible on label, New Hampshire, August 27, 

 1912, Solidago flowers. The type bears also a label with the 

 inscription ''T. D. 4335," [U. S. N. M.].
