doubt seems to have been one reason for his thinking neither of 

 his species could be L. ater, Putz. It appeal's to me that M. 

 Putzeys thinking this genus thoroughly specialised by the 

 moniliform antennae, and the form of the anterior thighs in the 

 (J, must have regarded this feature of small importance, and so 

 omitted to mention it. I have a specimen from the north of 

 Tasmania which seems undoubtedly to be L. strangulatus, Bates ; 

 it agrees thoroughly with M. Putzeys' description of L. ater (apart 

 from the transverse impression at back of head). I therefore 

 think the names synonymous, and in this belief have united them. 

 The puncturation of the elytral striae mentioned by M. Putzeys 

 in his description of L. ater, and referred to by Mr. Bates in his 

 remarks, is to my mind of no value, being, in all probability, 

 caused by long immersion in spirits of wine. 



Lychnus ater, Putzeys. 



L. ater, Putz., Stett. Ent. Zeit. 1868, p. 325 ; L. strangulatus, 

 Bates, Cist. Ent. ii, 1878, p. 317. 



(J. Form elongate, not convex. Black. Head not large ; a 

 strong transverse impression behind eyes ; frontal impressions 

 sti-ong, curved, diverging backwards ; a narrow lateral groove 

 from above each eye to base of mandible ; eyes rather prominent ; 

 post-ocular prominences strong, almost equalling eyes in size. 

 Prothorax depressed on disc, cordate, a little wider than long 

 (4| X 5mm), truncate in front and behind ; sides almost parallel 

 on anterior part from behind anterior angles to posterior marginal 

 puncture, decidedly narrowed, but not sinuate, to base ; lateral 

 border narrow, extending from anterior angles to slightly behind 

 basal angles, — these obtuse — ; median line lightly marked ; a 

 marginal puncture on each side about the middle, three other seti- 

 gerous punctures on the margin just behind each anterior angle. 

 Elytra not convex, oval (9| x 6 mm.), striate ; strise shallow, 

 lightly impressed ; interstices not convex ; shoulders rounded ; 

 base declivous to peduncle ; lateral border narrow, slightly 

 reflexed, extending from peduncle to apex ; a row of setigerous
