880 DIPTERA OF AUSTRALIA, 



mary of Exotic Tipulidse (Trans. Ent. Soc. Load. 1881, p. 363). 

 I have not seen Westwood's original description; there may be some 

 mistake. However, from careful comparison of specimens with 

 Macquart's and Thomson's descriptions, I cannot help concluding 

 that both refer to the same species. Thomson himself notices 

 the great resemblance of his species to G. viridis^ Westw., with 

 which he compares it, 



Ohs. 2. The above-described is undoubtedly C cenarthria viridis, 

 Thorns. The species has no claims to be separated from 

 Gynoplistia. 



Ohs. 3. Macquart gives the description of the 9 of G. viridis, 

 Westw., which corresponds with an old damaged specimen of this 

 sex before me, obtained by Mr. Masters in Tasmania. The lateral 

 borders of the segments are dark coppery, and the ovipositor is 

 fulvous. The male does not differ from Sydney specimens. 



B. Tibice with a pale ring.

9. — Length of antennae 0*110 inch ... 2-79 millimetres. 



Expanse of wings 420x0-140 ... 10-66 x 3-55 



Size of body - 0-420x0-085 ... 10 66x2-14 



Head black. Rostrum, palpi, and antennae dark brown, the 

 latter 17-jointed; flagellar joints 1-9 with a short obtuse branch, 

 gradually becoming longer to the fifth or sixth joint, from thence 

 diminishing in length ; tenth joint with a small projection on the 

 inner side ; first two branches directed almost outwards ; terminal 

 joint elongate, more than twice the length of the one next before 

 it, appearing as if made up of three compressed joints. Entire
