Australian and Tasmanian Malacodermidae. 113 



The species unknown to me are : — 



Tepperi, Blackb. — Evidently belonging to the mastersi 

 group as the prothorax is " half again as wide as long." 

 There are several species before me which might be this 

 insect, but as they do not agree exactly with its described 

 colours (even although Mr, Blackburn supposes these to be 

 variable) I prefer to leave them untouched for the present. 



Falmerstoni, Blackb. — The width of the prothorax is 

 not given, bub as the insect itself is described as closely 

 resembling the preceding species (except in colours), it 

 also is probably allied to mastersi. 



Mossmani, Macl. — Belonging to the mastersi group, but 

 with the upper surface entirely pallid. 



The others may be tabulated as follows : — 



A. Apterous. 



a. Elytra fasciate. alternatus, n. sp. 



aa. Elytra not fasciate. 



b. Large and comparatively robust . apterus, OIL 



bb. Small and very thin kershawi, n. sp. 



A A. Winged. 



B. Prothorax partly dark.* 

 c. Elytra entirely dark. 



d. Prothorax distinctly transverse in 



both sexes nobilitatiis, Er. 



(in part.) 

 dd. Prothorax distinctly transverse 



in female only pidchellus, W. S. Macl. 



cc. Elytra entirely pallid t fla v ipenni s, Ma,cl. 



ccc. Elytra dark with a subapical fascia . notophilus, Blackb. 

 cccc. Elytra dark at base and apex . . imperialis, Eedt. 

 ccccc. Elj'tra dark at base and maculate 



near apex curvipes, n. sp. 



BB. Prothorax entirely pallid. 

 C. Elytra entirely dark. 



e. Prothorax strongly transverse . . nobilitatiis, Er. 



(in part.) 

 ee. Prothorax at least as long as wide. 



* I have not included part of nigroterminalis here, as even when 

 present the dark marking of the prothorax is only of the nature of 

 a stain ; for the same reason part of viridipennis is not included. 



t There is occasionally an infuseate blotch about the scutellum.
