Australian and Tasmanian Malacodermidae. 157 



parts of the elytra very densely (more densely than in any 

 other species before me) punctate ; and the pallid triangular 

 spot common to both elytra does not extend quite to 

 the apex, but is distinctly truncated at a short distance 

 before it.

 {Figs. 52, 181.) 



The markings on the head of this species are variable 

 and to a greater extent than described by Blackburn. The 

 female differs from the male in having the head less 

 densely punctate and only the muzzle pallid ; the antennae 

 simple; the elytra are somewhat inflated posteriorly, and 

 the front tibiae are not entirely pallid. There are several 

 species having almost exactly similar elytral markings ; 

 but the 2nd joint of the male antennae renders the species 

 very distinct.

Laius major, Blackb., P. L. S., N.S.W., 1888, p. 1426. 

 {Figs. 53, 132.) 



The female of this species differs from the male in being 

 considerably longer (although no wider), the antennae 

 slightly shorter and simple ; the anterior tarsi simple ; the 

 prothorax more rounded and the elytral markings some- 

 what greenish and rather larger.

Laius sinus, Lea, P. L. S., N.S.W., 1898, p. 562. {Fig. 

 54.) 



In the original description the prothorax is described as 

 " slightly longer than wide " ; to the naked eye this appears 

 to be the case, but by measurement it is actually a trifle 

 wider than long.
