This species is readily distinguishable from the other 

 described species of the genus. Its group characters place it in 

 Group v., in which only two iridescent species have been pre- 

 viously described {gigantea, Burm., and lucifera, Blackb.), 

 from both of which it differs by, inter alia, its very much 

 smaller size, the female antennae terminating in four equal 

 (or nearly so) lamellae, the forehead scarcely visibly punctu- 

 late, etc. It does not fit into my tabulation of Haplonycha 

 (Tr.R.S.S.A., 1906, pp. 297, etc.), owing to my having used 

 the word "large" in characterizing the aggregate "A" on p. 

 301. In order to place it, the following must be substituted 

 for the first nine lines under Group V. : — 



A. Iridescent species. £ Joint 3 of maxil- 

 lary palpi conspicuously shorter than 

 joint 2]. 

 B. Frons conspicuously punctulate. 

 C. Pygidium but little nitid, closely 



sculptured, especially near base gigantea, BurmX?) 

 CO. Pygidium brilliantly nitid, its 



puncturation extremely sparse lucifera, BJackh. 

 BB. Frons scarcely punctulate ... Grifl&thi, Blackh. 



AA. Non-iridescent species. 



Northern Territory ; Port Darwin. Given to me by Mr. 

 H. Griffith. 



Petinopus. 



I have no further information to be recorded regarding 

 this genus, and have not seen any more examples than those 

 mentioned when I characterized the genus in 1898. The 

 unique species is probably a very rare one. 



Glossocheilifer. 

 Since I described G. labialis (Tr.R.S.S.A., 1898, p. 37) 

 I have obtained a male example of a second species of this 

 curious genus, of which the following is a description : —
