Family TYLIDAE 

 Subfamily Taeniapterinae 



Genus GRAMMICOMYIA Bigot 



1. GRAMMICOMYIA HALLI, new species 



Figure 72, a 



Male.— Length 8.5-9.5 mm., exclusive of ensiform hypopygial proc- 

 ess. Very similar to G. lergi Steyskal (1947, p. 7), differing as 

 follows : Anterior part of f rons bright creamy yellow, somewhat wider 

 than in G. hergi, pale centrally back to ocellar region ; third antennal 

 joint largely blackish, but brown basally ; anterior hump of mesonotum 

 rather flatter than in G. hergi, not rugulose, brown pruinose antero- 

 medianly. Pruinosity of venter and pleura rather thin. Middle and 

 hind femora very little swollen centrally, tapering to each end, dark 

 brown in middle. Hind tibiae black at base, grading into brown in 

 apical half ; middle tibiae wholly black. Copulatory fork as figured. 

 Wings as in G. hergi. Palpi flat, elongate-oval, with small hairs only, 

 dark brown, somewhat paler apically. 



Types. — Holotype, male, U.S.N.M. No. 58304, and two male para- 

 types, New Guinea : Finschhafen, November 9, 1944 (David G. Hall). 



Remarks. — ^The hind femora, swollen centrally, place this form in- 

 termediate between G. bergi, in which the femora are swollen basally, 

 and the more typical forms from farther west, which have the hind 

 femora strongly swollen distad of the middle.

Genus MIMEGRALLA Rondani 



3. MIMEGRALLA ALBIMANA (Doleschall) 



Taeniaptera albimana Doleschaix, Nat, Tijdschr. Nederl. Ind., vol. 10, p. 413, 



pi. 10, fig. 4, 1856. 

 Mimegralla alUmana (Doleschall) Hennig, Konowia, vol. 14, p. 198, 19S5. 



The various subspecies of M. albimana may be rather easily dis- 

 tinguished from other species by the following combination of charac- 

 ters: First posterior cell narrowly open; postvertical bristles lacking; 

 front wholly black (except frequently reddish anteriorly in M. a. 

 contraria) ; antennae reddish yellow, brownish apically or dorsally 

 only; hind basi tarsi (except extreme base) whitish.
