NO. 2128. NEW GENERA OF MUSCOID FLIES— TOWN SEND. 631 



not stout. Hind femora of male conspicuously pilose on the inside 

 and below, hind trochanters each with long thick curved tuft of hair. 

 Ventral plates of male normally not concealed by the overlapping 

 lateral sclerites; no pair of spined processes visible at extremity of 

 fourth ventral plate as in male of Cylindromyia. 



Two males : Australia (Koebele) ; Koorawatha, New South Wales, 

 1902 (H. Brown), through Froggatt, Length, 9 to 11 mm. 



OCYPTERODES,neAW genus. 



Genotype. — Ocyptera euchenor Walker, List IV, 1849, p. 696. 



Differs from Cylindromyia as follows: Basal segment of female 

 hypopygium shorter than anal segment; abdomen swollen, gradu- 

 ally widening, not of even width throughout after base. Second 

 antennal joint of female longer, third shorter. Second aristal joint 

 of female short. Male with four strong long appressed bristles on 

 median ventral line at liind edge of second abdominal segment; fe- 

 male shows weak ones. Female \^^thout any grasping spines on 

 venter, same as in Cylindromyia. 



NEODIONAEA, new genus. 



Genotype. — Dionaea nitoris Coquillett, Can. Ent., vol, 30, 1898, 

 p. 235. 



Differs from Dionaea as follows: Abdomen of female narrow and 

 equilateral, that of male shghtly widened. Forceps of female not 

 toothed, unarmed on inner surface save some minute spines and 

 bristles, terminal joint elongate. Only two median marginal macro- 

 chaetae on segments one and two in female, marginal row on seg- 

 ments two and three in male. Antennae distinctly separated. Cos- 

 tal spine vestigial. 



Dionaea timberla'kei Walton, Proc. Ent. Soc. Wash., vol. 16, 1914, 

 p. 91, also belongs to this genus. 



PARADIONAEA, new genus. 



Genotype. — LeucostomM atra Townsend, Trans. Amer. Ent. Soc, 

 vol. 18, 1891, p. 380. 



Differs from the rest of the group as follows : Female forceps meet- 

 ing apicaUy at acute angle, armed with teeth. First two abdominal 

 segments without marginal row of bristles, but with only median 

 marginal pair and laterals; third and fourth segments with marginal 

 row. Fourth segment of female with scattered hairs, but sub- 

 glabrous anteriorly. Hairs of abdomen not long. Proboscis short. 

 Epistoma produced downward, not projecting. Vibrissae above 

 oral margin, Frontaha narrow, averaging one- third of frontal 

 width in male, less than that in female, Tegulae not of extraordinary 

 size in male, but larger than in female.
