Australian and Tasmanian Malacodermidae. 135 



9th joint is very slightly but perceptibly wider than 

 the 8th or 10th, slightly shorter than the 11th, but longer 

 than any of the others except perhaps the 1st.

Heteromastix fusicornis, Blackb. {Tclepli(ynis), I.e., 

 p. 529. 



This species differs from McDonaldi in having the 

 scutellum (not mentioned by Blackburn) and head entirely 

 pallid, and more of the legs pallid. The 9th joint of the 

 male antennae is much the same as in McDonaldi, except 

 that it is larger, with its apical fovea larger and more 

 distinct ; and its head is smooth whilst in that species 

 it is rather coarsely punctate. The female (unknown to 

 Blackburn) differs from the male in having the head 

 somewhat narrower, the 9th joint simple (although it 

 is slightly wider than any of the others) and slightly 

 shorter than the 11th — which is longest of all.

Heteromastix pauxillus, Blackb, {Tclcpliorus), T. R. S., 

 S.A., 1886, p. 261. 



I have a specimen from the Rev. T. Blackburn bearing 

 a label in his writing "pauxillus, Blackb.," and agreeing 

 with his description except that it is much smaller (2| as 

 against ^\ lines).* 



The species is exceedingly abundant and widely distri- 

 buted in Tasmania, where it occurs on flowers. The male 

 is smaller and thinner than the female, with longer (but 

 still simple) antennae, longer legs and penultimate segment 

 of abdomen semicircularly excised.

? gagaticeps, Lea, I. c, 1895, p. 233. (Figs. 30, 36.)t 



Telephorus galeatus, Blackb., is certainly a Heteromastix, 

 and quite possibly my gagaticeps, in which case the latter 



* Mr. Blackburn writes me, however, that 4J lines was a misprint 

 and should have been 2J.
