T2 INSECUTOR INSCITI^' MENSTRUUS 



very elongate; third antennal joint not rounded at tip, but 

 truncate and subangular, much widened apically especially in 

 male ; wings shorter in proportion ; apical cell not so elongate 

 and not so widely open, ending farther before tip ; apical cross- 

 vein not bowed in conspicuously, a wrinkle at its origin which 

 latter is not so close to hind margin ; discal macrochastse of 

 second segment sparse, there being only a pair or two of discals 

 the same as on third and anal segments. Anal segment with 

 buttocks-bunches of macrochastae in both sexes. Front tarsi 

 of female much widened. 



Pictoepalpus clarus, new species. 



Length of body, 10 to 11 mm. ; of wing, 9.5 to 10.5 mm. 

 Three males, one taken at Tamboraque, Peru, about 9,000 

 feet, April 3, 1910 ; the others taken at Matucana, Peru, about 

 8,000 feet, August 16, 1913, and May 1, 1914, the last being 

 TD4356 (Townsend). 



Ground-color clear light yellow. Head with silvery pollen, 

 that of facial plate white, the rest of head with a golden tinge 

 even including front. Frontalia and first two antennal joints 

 rufous, third joint and arista black. Mesoscutum and scutel- 

 lum wholly clear testaceous, silvery poUinose with a faint 

 golden tinge, leaving more or less distinct remnants of seven 

 narrow vittae ; pleurae, coxas, and femora practically the same 

 testaceous shade as mesoscutum; tibiae rather more fulvous, 

 metatarsi rufous, rest of tarsi black. Abdomen broadly light 

 yellow on sides of first three segments, leaving a clear tes- 

 taceous subtriangular marking on second and third segments, 

 that of third segment larger than that of second, a small fleck 

 of the same color on lateral hind angle of second segment, 

 a patch of same color in middle of first segment beneath 

 scutellum, the anal segment entirely the same color extending 

 on hind lateral angles of third; the testaceous portions of 

 abdomen are clothed with the same pollen as that of mesoscu- 

 tum. Venter wholly clear light yellow, except anal segment 

 and narrow hind corners of second and third segments. In 

 some specimens the testaceous of thorax and abdomen is 

 considerably darker, especially on median triangles of abdomen
