31 S Mr. Bates on new species of 



frontalibus extus curvatis, intus ramxim brevem emittentibus : 

 tliorace cordato, antice vix rotuudato-dilatato, post medium iisciue 

 ad angiilos posticos valde angustato, his rotuudatis : elytris dorso 

 planatis, striis vix conspicuis, interstitiis planissimis. 



Femora antica $ subtus prope medium fortiter dilatata fere 

 dentata ; ? ovata modice incrassata. Long. 19-21 mm. ^ , ? . 



Agrees with Mr. Putzeys' description of his genus Lychnus ; 

 whicli, however, contains no mention of the remarkable constric- 

 tion of the head behind the eyes. The present species must 

 nevertheless, be closely allied to L. ater. In five examples $ , 

 I fail to detect any trace of punctuation in the striae, and the 

 latter are extremely faint, except near the apex, where they are 

 more pronoimced, owing to the elevation of the interstices. 

 In one of the examples 9 j hoAvever, the stria; are distinctly 

 punctured.

Lychnus striatiihis. 



L. strangulato simillimo, differt tantum statura minori elytris- 

 que distinctius striatis interstitiis convexis. Niger, minus niti- 

 dus ; elytris oblongo-ovatis, pauUo august ioribiis et supra miims 

 planatis. Long. 17 mm. $ . 



Differs fi-om L. strangulatus only in being smaller, propor- 

 tionately narrower, and in the elytra being more distinctly 

 striated, or rather the feebly or not at all incised stria? are 

 separated by convex interstices. The strisE have no traces of 

 punctuation. In its narrower, more oblong and convex form 

 it resembles the ^ of L. strangulatus more than the $ ; but 

 both the specimens before me are clearly males, having the 

 broad, sub-dentiform dilatation of the undersurface of the 

 anterior tibite.

 Mr. Janson has a third example. 



A third species of Lychnus, taken l)y Mr. Atkinson in 

 Northern Tasmania, is convex and punctate-striate in both 

 sexes. This may possibly be the L. ater of Putzeys, if we may 

 suppose that author to have overlooked the occipital strangu- 

 lation.
