486 NOTES ON AUSTRALIAN COLEOPTERA, 



An extremely distinct species which it is possible ought not to 

 be placed in Heteronyx, as T have not been able to examine the 

 inner organs of the mouth. Its elytra much narrower at the base 

 than the base of the prothorax and then arcuately dilated to 

 considerably beyond the middle (where they are much wider than 

 the prothorax) give it a facies out of harmony with its congeners; 

 the shortness of the elytra (their length not exceeding the width 

 by much more than a quarter of the latter) is also unusual. 



This insect, in my tabulation of Heteronyx, would fall in the 

 1st section (P.L.S.N.S.W., 1888, pp. 1328, &c.) under "FF" on 

 page 1329 beside//, spretus, from which, inter alia multa, its very 

 much larger size will distinguish it. H. lilliputanus, Blackb., 

 (described since the tabulation was published), also falls under 

 "FF" on p. 1329, but is still smaller than spretus. The three 

 species probably attributable to "Section I," which I have not 

 succeeded in identifying, are all very different, 



Victoria; under a stone on the summit of Baldi in the Victorian 

 Alps, at an elevation of more than 6000 feet. 



Heteronyx terrena, sp.no v. 



Sat elongatus, postice vix dilatatus ; minus nitidus, pallide 



ferrugineus, antennarum clava testacea; pilis brevibus pallidis 



sat crebre vestitus; crebre subtilius sat sequaliter punctulatus ; 



labro clypeum baud superanti ; antennis 9-articulatis ; coxis 



posticis metasterno plus quam paullo brevioribus ; unguiculis 



appendiculatis ; unguiculorum posticorum parte basali quam 



pars apicalis multo longiori. [Long. 4, lat. 2 lines. 



A clay-coloured species closely resembling in miniature //. piceus, 



Blanch., but a little narrower and more parallel in outline, with 



the hind coxa a little shorter in proportion to the metasternum, 



and the appendiculation of the hind claws nearer to the apex; the 



prothorax, moreover, is evidently less transverse, being not more 



than | again as wide as long. I do not observe any other respects 



in which the characters differ from those of //. piceus. 



The specimen mentioned in P.L.S.N.S.W., 1889, p. 1228, as 

 'My a small var. of //. piceus is this species.
