Type.—d'; West Coast of Greenland, 1891, (Mengel and 

 Hughes, on the Peary Expedition), [A. N. S. P., Type no. 6227]. 

 Allotype and parnfypes. — Eight specimens, topot^ypical. 



Limnophora angulata sp. n. 



Male. — Color as in extensa. 



Differs from extensa in being larger, in having the hairs on body and legs 

 longer, the bristles on mid and hind femora longer and more numerous, 

 the hypopygium larger (fig. 25), and the incision in fifth sternite deeper 

 (fig. 26). 



Female. — Larger than the female of exlcti.^tn, with the vibrissal angle less 

 ))roduced (fig. 38), and the mid and hind femora more eonspieuoiisly bristled. 



Length, 6 to 7.5 mm. 



Type. — cf ; West Coast of Creenland, 1891, (Mengel and 

 Hughes, on the Peary Expedition), [A. N. S. P., Type no. ()228|. 

 Allotype and poratype.s. — Thi'ce sp(>einiens, topotypieal. 



Limnophora pearyi sp. n. 



Mdlr. — Similar to extensa in color, the wings darker and the spots on 

 abdomen more distinctly separated in middle. 



Eyes separated by width across posterior ocelli; vibrissal angle less pro- 

 duced than in extensa (fig. 35). Abdomen cylindrical, incision in fifth ster- 

 nite wedge-shaped. Armature of legs as in extensa, but the hind femur 

 lias the antero-ventral bristles confined to apical half and the posteio-ventral 

 surfat^e with very few weak bristly hairs on basal third. 



Female. — Similar to tlie female of extensa, but the vibrissal angle less pro- 

 duced, and the hind femur as in male, except that the postero-ventral surface 

 is bare. 



Length, 4.5 to 5.5 mm. 



Type. — cf; West Coast of Greenland, 1891, (Mengel and 

 Hughes, on the Peary Expedition), [A. N. S. P., Type no. 0229]. 

 Allotype and paratype. — Two specimens, topotypieal. 



Limnophora novae-angliae sp. n. 



Male. — Deep black, shining. Dorsum of thorax slightly gray pruinescent, 

 that of abdomen, except on the spots, densely so. Basal tergite entirely 

 black, second with two very large subcjuadrate black spots, third with a 

 pair of smaller subtriangular spots, both pairs narrowly separated, fourth 

 with a poorly-defined central spot. Wings grayish, slightly infuscated at 

 bases and on cross-veins. Calyptrae and halteres yellow. 



Eyes sei)arated by twice the width across posterior ocelli; orbits linear; 

 l)arafacials nearly as wide as third antennal joint; cheek about three times 

 as high as width of parafacial; setulae continued about one-third of the way 

 from vibrissa to base of antenna; third antennal joint angulated at ajiex
