concealed by scales. Antennae thin, inserted slightly nearer 

 apex than base of rostrum ; club moderately long. Prothorax 

 about as long as wide, sides moderately rounded, base slightly 

 wider than apex; with dense but normally concealed punc- 

 tures. Elytra rather narrow, much wider than prothorax, 

 parallel-sided to near apex; with rows of rather large, but 

 more or less concealed punctures. Length ( <5 , 9)> 2-2J mm. 



9 • Differs in having the rostrum considerably longer and 

 thinner, its clothing not continued beyond the basal third, 

 antennae inserted slightly nearer the base than apex of 

 rostrum, and abdomen more convex. 



Hab. — South Australia: Lucindale (B. A. Feuerheerdt, 

 his No. 742), Coorong (S. A. White), Port Lincoln; Western 

 Australia: Geraldton (A. M. Lea). Type, I. 7607. 



Rather close to ruber, but elytra conspicuously bimaculate 

 and tarsi black; the two conspicuous spots on the elytra are 

 due to the partial or complete absence of scales ; they are 

 about two-fifths from the apex and close to the suture. The 

 head, rostrum (part of this is usually diluted with red), 

 prothorax (parts of the sides are usually diluted with red), 

 scutellum, and most of the upper-surface and of the antennae 

 and tarsi are black; the suture and margins of elytra are 

 usually somewhat infuscated. On specimens in perfect con- 

 dition each of the seriate punctures on the elytra appears to 

 be partially filled by a stout seta or scale, but there are no 

 true setae on the interstices, the clothing there consisting 

 entirely of soft scales. 



Epacticus nigrirostris, Blackb. 



The type of this species was unique in the Blackburn 

 collection, and is now in the British Museum. There are, 

 however, numerous specimens before me from Port Lincoln, 

 Lucindale, and Kangaroo Island that agree with the brief 

 description, and probably belong to the species. 



The species is somewhat variable in its scales; on the 

 elytra they are frequently whitish, but are sometimes mixed 

 with somewhat darker ones, these occasionally having a 

 maculate or vaguely fasciate appearance. The rostrum whilst 

 usually black, is occasionally diluted with red at the tip ; it is 

 distinctly shorter and less curved on the male than on the 

 female. 



Tychius minutissimus, Boh. 



Fourteen specimens from Ooldea probably belong to this 

 species, they are structurally (sex for sex) identical with the 

 specimens previously < 29 ) recorded as belonging to the species 



(2 Q > Ann. Soc. Ent, Beige. 1910, p. 105.
