318 Mr. Bates on new species of 



frontalibus extus curvatis, intus ramiim bi'evem emittentibus : 

 tliorace cordato, antice vix rotundato-dilatato, post medium usque 

 ad angulos posticos valde angustato, his rotundatis : elytris dorso 

 planatis, striis vix conspicuis, interstitiis planissimis. 



Femora antica $ subtus props medium fortiter dilatata fere 

 dentata ; 9 ovata modice incrassata. Long. 19-21 mm. $ ,^ . 



Agrees with IMr. Putzeys' descriptiou of his genus Lychnus ; 

 which, 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 pronounced, owing to the elevation of the interstices. 

 In one of the examjales 9 j however, the stria3 are distinctly 

 punctured.

Lychnus sti'iatuhis. 



L. strangulato simillimo, differt tantum statura minori elytris- 

 que distinctius striatis interstitiis convexis. Niger, minus niti- 

 dus ; elytris oblongo-ovatis, pauUo angustioribus et supra minus 

 planatis. Long. 17 mm. $ . 



Differs from 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 striae are 

 separated by convex interstices. The stria3 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 cleaidy males, having the 

 broad, sub-dentiform dilatation of the undersurface of the 

 anterior tibia;.

 Mr. Janson has a third example. 



Al third species of Lychnus, taken by 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.
