480 NOTES ON AUSTRALIAN COLEOPTERA, 



3 segniento ventrali apicali postice haud emarginato, utrinque 



puncto setifero instructo, ad latera profunde sinuato. 

 9 segmento ventrali apicali postice magis late rotundato, 

 utrinque punctis setiferis 2 instructo, ad latera profunde 

 sinuato ; elytris minus nitidis paullo minus fortiter striatis. 



[Long. 3?, lat. If lines. 

 The elytra are considerably more strongly striate than in L. 

 major and the hind angles of the prothorax less explanate and 

 more rectangular. The hind angles of the prothorax not rounded 

 off will separate this species from all the others of the genus yet 

 described. The male sexual characters are much like those of L. 

 flavocinctus.

CYCLOTHORAX EYRENS1S, Sp.nOV. 



Modice convexus ; nitidus; an tennis palpis pedibusque testaceis; 

 prothorace leviter transverso, trans basin punctulato haud 

 depresso, utrinque ante basin fovea sat perspicua instructo, 

 lateribus valde rotundatis ante basin fortiter sinuatis, angulis 

 posticis acute dentiformibus ; elytris manifeste 6-striatis, 

 striis sat fortiter nee crebre punctulatis postice obsoletis. 



[Long. 2^, lat. 1 line (vix). 

 Differing from all the other Australian species of Gyclothorax 

 known to me by the sharply dentiform hind angles of its 

 prothorax, this species is nearest I think to C. peryphoideS) 

 Blackb. ; it is however more convex than that insect with much 

 more distinctly striate elytra, the stria? being more strongly 

 punctulate. All the stria? are abbreviated behind, and are 

 successively shorter from the sutural one. Besides the 6 stria? on 

 the disc of the elytra there is as usual in the genus a stria near 

 the external margin.

Cyclothorax pdnctipennis, Macl. 



In P.L.S.KS.W, 1888, p. 1388, I made some remarks on this 

 species founded on a specimen named for me by Sir W. Macleay.
