This species is smaller than the preceding, and the 

 variegated wings render it much more conspicuous. In 

 the anterior legs the tibife are 6 lines and the tarsi are 

 10 lines long. In the hind legs the tibias are 9 lines and 

 the tarsi 16 lines long, of which the basal joint occupies 

 11| lines.

Habitat in Australia. 



In Mus. Britann. 



The outer dark brown apical fascia extends from the 

 tip of the wing across the terminal veins and the apical 

 margins of the small subapical and posterior discoidal cell, 

 uniting with the dark-clouded posterior longitudinal dis- 

 coidal vein, which is clouded with broAvn throughout its 

 whole length to the posterior margin of the wing. 



t have referred this insect to the genus Ozodicera, Mcq. 

 (= Hemicteina, Westw. Zool. Journ. vol. v. p. 450), on 

 account of the similar arrangement of the wing veins, and 

 the slightly ramose structure of the 3rd and five following 

 joints of the antenna3. In the sj^ecies here described, how- 

 ever, each of these joints emits two short slender branches, 

 and the filiform terminal part of the antennas consists of 

 six joints (fifteen in all), whereas in the Brazilian type of 

 the genus ( Oz. gracilis, Westw., 1. c.) there are only single 

 bi'anchlets emitted from the intermediate joints, and the 

 tex-minal portion only consists of four joints (or thirteen 

 in all).
