THE CANADIAN ENTOMOLOGIST 207 



Dicranomyia (Thrypticomyia) fumidapicalis, sp. n. 



General coloration dark brown; thoracic pleura yellow; legs dark brown, 

 the tarsi largely white; wings hyaline basally, with about the apical fifth strongly 

 infuscated. 



Male. — Length 6 — 6.5' mm. ; wing 6.7 mm. 



female. — Length about 5.5 mm. 



Described from alcoholic specimens. 



Rostrum and base of palpus obscure brownish yellow; terminal palpal 

 segments dark brown. Antennae dark brown, the flagellar segments with a 

 short basal pedical and with long, unilaterally arranged verticils as in the males 

 of this group. Head dark. 



Mesonotum dark brown, the median area of the scutum and the postno- 

 tum paler. Pleura obscure yellow, the mesosternum infuscated. Halteres elon- 

 gate, brown. Legs with the coxae and trochanters yellowish ; only the fore legs 

 remain attached to the body ; femora, tibiae and about the basal third of meta- 

 tarsi dark brown; remainder of the tarsi except the terminal segment white; 

 fore metatarsi with a small tubercle near the base. Wings hyaline with about 

 the apical fifth strongly infuscated, this including almost all the wing beyond the 

 level of the cord ; stigma oval, still darker brown ; veins dark brown. Venation : 

 Sc, before the origin of Rs, Ssg ending just beyond the origin of Rs, Sc, alone 

 being a little longer than the basal deflection of Cuj ; Rs long, arcuated at 

 origin; r near tip of Rj ; cell 1st Mo long and narrow, longer than vein M;; be- 

 yond it; basal deflection of Cu^ beyond midlength of cell 1st IVL. 



Abdomen of male long and slender, dark brown; sternites a little paler. 



Habitat. — North Queensland.

Allotopotype, $. 



Paratopotypes, 2 c^'s. , 



The apically darkened wings are very conspicuous. 



Subgenus Idioglochina, subgen. n. 



Flagellar segments with the inner face strongly produced into flattened 

 disks, giving a subserrate appearance to the antennae, the periphery of each disk 

 with a series of about six spinous bristles. Wings with costa and radius greatly 

 mcrassated ; r long, arcuated ; cell R , very large, due to the strong bending 

 of R2+,, toward R^^g near its"~origin. 



.Type of the subgenus. — Rhipidia tusitala Alexander (Samoa). 



Dicranomyia de beauforti de Meijere (Papuan subregion) is also a mem- 

 ber of this subgenus. 



Subgenus Euglocliina, subgen. n. 

 Wings very long and narrow, cuneiform, entirely without an anal angle; 



Rs very short, about equal to the basal deflection of R^^ , originating far out 

 toward the wing-tip, the cord lying beyond five-sixths of the wing-length; cells 

 beyond the cord unusually short and crowded ; vein 2nd A running parallel to Cu, 

 at the margin separate or fused with the tip of Cu,. 



Type of the subgenus. — Dicranomyia cuneifoniiis de Meijere. (India 

 to Java).
