NEW MUSCOID FUES FROM THE ANDEAN MONTANYA 155 



rather than subquadrate. Anal width of abdomen fully two-thirds basal 

 width in both sexes. No discal abdominal macrochaetae except the 

 buttocks-bunches of anal segment which occupy less than one-half the 

 length of segment. All the tarsi father heavy Jind thickened, front tarsi 

 of female hardly wider than others. 



Reproductive habit, probably leaf-larviposition of colored maggots. 



Type, Melanepalpus alhipes, new species. 



Melanepalpus albipes, new species. 



Length of body, 15 mm.; same to end of abdominal spines, 16.75 

 mm. ; of wing, 1 5 mm. One female, east base of Huascaray Ridge, 

 about 7,000 feet, September 22, 191 1 , on foliage. 



Coloration aJmost identical throughout with that of Eulasiopalpus 

 alhipes T., the only differences being as follows : Head more silvery, 

 without so deep a smoky tinge; brassy-smoky eirea of cheek-grooves 

 extending down to vibrissae and peristomalia. Parafrontals much darker, 

 frontalia not so black when viewed obliquely from in front ; no peJpi. 

 Thoracic pollen so indistinct as not to indicate vittae. Abdomen hardly 

 at all shining ; venter with a thin coat of pollen showing in patches in 

 oblique view, hardly apparent above except on sides of anal segment. 

 Legs, wings, and tegulae same. 



This is another case of similar coloration in species of distinct genera 

 inhabiting the same locality, the present species being almost a duplicate 

 of Eulasiopalpus alhipes and Eudejeania huascaraya so far as colora- 

 tional effect and general form go. Even minute details of color largely 

 agree in this species and E. alhipes. 



Melanepalpus fulvus, new species. 



Length of body, 1 2 mm. ; same to end of spines, 1 3.5 mm. ; of wing, 

 scant 1 2 mm. One male, Uruhuasi Bridge, about 6,500 feet, Febru- 

 ary 15, 1910, on flowers of Baccharis sp. 



Head wholly silvery-white pollinose, only the pcirafrontals greenish- 

 dusky wnth a brassy shade to the pollen extending on orbits and upper 

 occipital area. Frontalia pale velvet-brown. Lunula and first two anten- 

 nal joints yellowish-brown, more or less shining ; third antennal joint and 

 arista brown. OccipiteJ pile gray, other head pile black. Thorax dark 

 in ground color, with an old-gold pollen and a faint grayish bloom giving 

 way on sternum to cinereous ; the usual four narrow vittae, the median 

 pair faint. Scutellum and abdomen reddish in ground color, the whole
