BETHELIUM SIGNIFERUM Newm. 



This species \aries considerably in size ( 5 ^-O nun. I. and in llie intensity 

 and extent of its markings. It occurs in Queensland. New .'^outli Wales. \'ic- 

 toria, and South Australia, as well as in Tasmania.

Numerous specimens from Queensland ( C'oen River and Cairns), and Xew 

 South ^\'alcs (Tweed Ri\er and Dorrigo), in structure agree so well with B. 

 sifivifcyitm that I cannot regard them as rejiresenting more than a variety; but 

 they ditTer from normal specimens in being considerably paler, with the dark 

 eivtral markings narrower and less extended; on the elytra there appears to be 

 a narrow and somewhat irregular X. but near the upper edge of each side of 

 the X there is usually a short spur, directed towards, but not reaching, the basal 

 incurvature ( on the typical form of sic/iiifcnim this spur is always present and 

 more extended), there is also at about one-fourth from the apex a narrow fascia 

 somewhat obliquel}' placed on each elytron, and not joined to the X along the 

 suture, on some specimens. howe\er. it almost joins the X ; on two specimens 

 the X only is present, and on one sjjecimen only the posterior half of the X, 

 There are usuallv three disconnected spots on the iironotum. but sometimes the 

 two front ones are connected with a short apical infuscation. and the hind one 

 with a basal infuscation ; on one specimen the three spots are almost connected. 

 There is usually a dark spot between the eyes.

The colour of the prothorax of this species \aries from reddish, with or 

 without a slight infuscation at the base and apex, to entirelv ilark ; the ground 

 colour of the basal two-thirds of the elytra also varies from red to almost black, 

 and the antemedian fascia varies in width and completeness. There is nothing 

 in the description of Ectosticta ehwata inconsistent with its having been drawn 

 uji from one of the many slight \arietal forms of the sjiecies. A cotvpe of 

 B. tricolor, which agrees well with the description ( i ) . also belongs to that 

 species; and B. luumiitni must also be referred to it. the small size, and narrow 

 antemedian fascia, being quite common variations. The description of B. black- 

 burni seems also to have been drawn up from a dark Tasmanian form of the 



(1) This note was partly drafted before I had seen Gahans reference of li. tricolor to 

 li. sitiiillimum. one of the named varieties of B cleroiilcs.
