Studies on Tipulidae II. 211 
The venation of the species which I have seen comes nearest to 
those of ‚Poecilostola and Dactylolabis (comp. Monogr. ete. IV, 
Tab. 2, f. 7); that is, the proximal ends of the first and second sub- 
marginal and of the first posterior cells are almost in a line, the 
second submarginal but slightly exceeding the others; the tip of the 
auxiliary vein is more or less opposite the proximal end of the se- 
cond submarginal cell, and has the crossvein at its tip; the tip of 
the first longitudinal vein is nearly opposite the middle of the anterior 
branch of the second vein; the marginal crossvein is at the tip of 
the first longitudinal, or very near it; there are five posterior cells; 
the petiole of the second rather long (@. jucunda from Celebes has 
only four posterior cells); the discal cell closed, comparatively small, 
with the great crossvein nearly opposite its middle; seventh vein 
more or less distinetly sinuated. Legs comparatively strong, especially 
the last pair; tibiae with spurs; empodia distinet. Male forceps 
Limnophila-like; the abdominal segments preceding it seem to offer; 
in different species, some characteristie structures. 
I possess a species from New m in which the wings in 
both sexes are rudimentary. 
Caenarthria Thomson is a Gynoplistia; I do not see any dif- 
ference. Patria: Australia. 
Cloniophora Schin. Wien. Ent. Mon. 1866; Reise d. Novara etc. 
Dipt. p. 40, is said to differ from Gynoplistia prineipally in the 
structure of the antennae, but it is not said in what the difference 
consists. If @. subfasciata Walk. (type of this genus) and perhaps 
some other New Zealand species really constitute a separate group, 
deserving to be separated from Gynoplistia, this group should be 
more distinetly defined. For the present it is better, I think to take 
those species for Gyneplistiae. 
I have expressed my doubts about Gynopl. annulata Westw. 
(Lond. and Edinb. Phil. Mag. 1835, p. 280; Tr. Ent. Soc. Lond. 1881, 
p. 371, Tab. 18, f. 7, antenna) said to be North American; compare 
Monogr. N. Am. Dipt. Vol. I, 1862, p. 13. This species has not 
turned up in North America yet. 
Cerozodia. 
Westwood, Lond. and Edinb. Phil. Mag. 1835, p. 281; Trans. Ent. 
Soe. Lond. 1881, p. 379; Tab: 19, f. 13. 
Ozocera Westwood, Zool. Journ. Vol. V, Tab, 22, f. 5, antenna 
(nee Ozodicera Macq.) 
The originally described species is from Swan River, Western 
Australia.
