AUSTRO-MALA.YAN DIPTERA 483 



Abdomen petiolate, club-shaped ; first segment long, petiolate , 

 bell-shaped at the end ; the petiole bears two knots ; the first , 

 near the root , has a sharp point on each side ; the second , in 

 the middle of the segment, forms a transverse ridge. The ab- 

 domen of the female has only four joints before the ovipositor; 

 the latter is flat, not longer than the preceding segment, dy- 

 popygium of the male small, bent under the abdomen. 



Legs moderately long and rather slender, without any spines 

 or bristles ; middle tibiae with a short spur ; the hind tibiae have 

 a weak and indistinct one. 



Judging from Macquart's description of his genus Omalocephala 

 (D. R. II , 3 , 231) , which he refers to the Sepsidae^ it has a 

 good deal in common with Anguitula. It differs in the structure 

 of head and front , of the abdomen, which is said to have seven 

 segments; the scutellum is without spines etc. Loew Monogr. 

 Ill, 21 and 23 refers it to the Ortalidae. 



Phytalmia cervicornis Gerstaecker, Stett. Ent. Z. 1860, 173, 



Tab. 2, f. 4. (New Guinea). 



Syn. Elaphomyia cervicornis Saund. V, oct. 1861, N. S. pt. X, Tab. 12, 



f. 4-5. 



Occurs, as M.^ Beccari told me , in woods , on the trunks of 

 trees. 



14 c/, 6 9 specilli, from Ramoi , N. Guinea, June 1872 {L. 

 M. D'Albertis) ; Febr. 1875 (Beccari) ; Andai, N. Guinea, August 

 (L. M. D'Albertis). 



NB. D.^ Gerstaecker's Phytalmia being earlier in date has 

 the priority over Elaphomyia Saund. The spines on the under- 

 side of the front femora exist in the male only. 



Of the five species, described by M."" Saunders, only three 

 are really Elaphomyiae; the Elaphomyia brevicornis is a com- 

 pound of two species, for which I propose the genus Biplochorda. 

 E. polita (described much earlier , under another name , by 

 Guérin) may remain in the genus Anguitula j, introduced by 

 M."^ Walker.
