LIII. — Neiv or little-known Tipulidse (Dipfera). — VII. Aus- 

 tralasia?i Species. By Charles P. Alexandeh, Ph.D., 

 Urbana, lUiuois, U.S.A. 

 The species of crane-flies discussed in this instalment are 

 mainly from North Queensland, and were received through 

 the kindness of Mr. Alan P. Dodd and Dr. James F. 

 Ulingworth. Mr. Edwards has sent me for study a few 

 specimens from Fiji, presented by the Imperial Bureau of 

 Entomology, and a few additional species from Tasmania. 

 I am very deeply indebted to the above-named gentlemen 

 for the privilege of studying these specimens. .The types are 

 preserved in the collection of the writer, except where stated 

 to the contrary. 



Dicranomyia {Thrypticomyia) mic7'0stigma, sp. n. 



General coloration dark brown ; vertex silvery grey ; legs 

 dark brown, the tarsi white, the basal third of the metatarsi 

 dark brown; wings nearly hyaline, very slightly darkened 

 apically; stigma very small; Sc short, Sc^ terminating a 

 distance before the origin of Rs that is approximately as 

 long as the basal deflection of Cu^. 



Female. — Length about 5'5 mm. ; wing 5 mm. 



Rostrum obscure yellowish testaceons ; palpi dark brown. 

 Antennae dark brown, the terminal pedicels of the flagellar 

 segments conspicuous, nearly one-half as long as the basal 

 enlargement. Head with the vertex clear silvery grey. 



Mesonotum brown, the humeral regions and lateral 

 margins of the prsescutum slightly paler. Pleura obscure 

 brownish yellow. Halteres elongate, brown. Legs with 

 the coxje and trochanters testaceous ; femora and tibife dark 

 brown; tarsi white, the basal third or slightly less of the 

 metatarsi dark brown. Wings nearly hyaline, the apex 

 beyond cell 1st il/g very faintly clouded; stigma small, 

 brown ; veins dark brown. Venation : Sc very short for a 

 member of this subgenus, Sci ending far before the origin 

 of Rs, the distance being as long as or longer than the basal 

 deflection of Cui ; Sc2 some distance from the tip of Sci, the 

 latter alone from one-half to two-thirds the basal deflection 

 of Cui ; Rs strongly arcuated to subangulate at origin ; 

 supernumerary cross-vein in cell Sci rather indistinct, slightly 

 variable in position ; inner end of the elongate cell 1st M^ 

 about in alignment with the inner end of cell R^ ; cell 

 1st M2 about as long as the longest veins issuing from it ; 

 basal deflection of Cui beyond mid-length of cell 1st M^.
