1919] Crane-fly of Hawaiian Islands 27 



suggestion has been made that it would perhaps be better to 

 consider these diverse Limnobiine genera as lesser groups, such 

 as sub-genera, but in my opinion no benefit would be derived 

 from such an action, since it would be exactly as difficult to 

 separate and define these sub-genera. These various exotic 

 genera are probably valid, but Goniodineura van der Wulp is 

 doubtfully distinct from Libnotes. 



Genus Dicranomyia Stephens. 

 Dicranomyia stygipennis, sp. n. 



Coloration dark brown throughout, including the wings. 



Male: Length, 6-7.5 mm.; wing, 7.5-8 mm. 



Female: Length, 6.4-8.5 mm.; wing, 7.8-9 mm. 



Rostrum and palpi dark brown. Antennae dark brown throughout, 

 the flagellar segments elongate-oval. Head dark brown. 



Thorax dark brown, the pronotum a little yellowish. Legs dark 

 brown, the extreme base of the femora a little paler. Halteres dark 

 brownish black throughout. Wings with a strong brown suffusion; 

 stigma rather distinct, of a somewhat darker brown. Venation: Sc 

 ending about opposite the origin of the sector, Soi close to the tip of 

 Sc\\ Rs about twice the length of the basal deflection of .^4+5; 

 cell 1st Mo closed; basal deflection of Cui at the fork of M. 



Abdomen dark brown. Hypopygium of male with the ninth 

 pleurite small, only about four-tenths the length of the ventral pleural 

 lobe; ventral lobes large, fleshy, the basal inner angle suffused inwardly, 

 near its base with two powerful spines; dorsal lobes short, stout, slightly 

 curved, the tip of each produced into a slender, blackened spine. 



Holotype, cf, Waianae Mountains, Oahu, altitude 2000 

 feet, March 5, 1917 (J. F. lUingworth). 



Allotype, 9 , with the type. 



Paratypes. Very numerous specimens of both sexes, from 

 the type locality; Kaupo, Maui, altitude 2000 to 4000 feet, 

 January 1, 1915 (H. T. Osborn) ; Haleakala, Maui, altitude 

 9000 feet, September 27, 1914 (H. T. Osborn). 



This common fly is notable by its dark coloration. I would 

 have identified it as being D. brunnea Grimsh. (1901) except 

 for the discrepancy in the coloration of the wings. In any case, 

 Grimshaw's name is preoccupied by D. brunnea Doane (Journ. 

 Ent. N. Y. Soc, Vol. 8, p. 184; 1900), a fact that was pointed 

 out by the author several years ago (Psyche, Vol. IS, p. 194; 

 1911). 



Dicranomyia grimshawi, 110m. n. 



New name for D. apicalis Grimsh. (1901), not D. apicalis 

 (Wied.) (182S).
