rows ; also tlie punctures on the thorax are finer, and the head 

 is more elongate and depressed, without any defined puncture- 

 less space (in G. Adelaides n distinct though small central space 

 is devoid of puncturation). The elytra by measurement are 

 scarcely so long as the thorax. [It should be noted that 

 (owing no doubt to their greater width) they appear to the 

 eye considerably shorter in proportion than they really are.] 

 An unfortunate accident caused the destruction of the male 

 specimen alluded to in my former description, and I know not 

 to which species it appertained. 



Port Lincoln. 

 C. elegans, sp. nov. Gracile ; nitidum ; capite prothorace et 

 elytris (nonnullis exemplis) plus minusve piceis vel rufo- 

 piceis, antennis palpis mandibulis pedibusque testaceis 

 antennarum articulo 1° maxime elongate, ceteris multo 

 minoribus (tamen sat longioribus quamlatioribus), 3° 2° 

 evidenter longiori, capite minus elongato, sat sequaliter 

 (disco fere Isevi excepto) sparsim sat fortiter puuctulato ; 

 prothorace tertia parte longiore quam latiore, postice 

 angustato, capite minus augustiori, disco seriatim lateribus 

 confuse punctulatis, spatio medio longitudinali lato 

 alteroque utrinque angu-stiori IcTvibus ; elytris capite sat 

 latioribus prothorace sat longioribus, crasse leviter sat 

 crebre vix seriatim punctulatis ; abdomine obsolete sat 

 crebre punctulato, segmentis 6-7 piceolis. Long., 6^-7 mm. 

 Maris segmento apicali subtus late profunde inciso. 

 This species is very probably allied to C. fractum, Fauv., 

 -^hich it resembles in having the third joint of the antennae 

 longer than the second, but besides difference in colour (the 

 tibiae and palpi are quite clear testaceous) it has the sub- 

 apical joints of the antenna:' exceptionally elongate, and I 

 do not think so keen an observer as M. Fauvel could have 

 failed to notice the evident contraction backwards of the 

 thorax, of which there is no mention in the description of 

 C. fr actum. 



The colour of the head, thorax, and elytra vary considerably ; 

 in the darkest specimen I luive seen the head and elytra are 

 nearly black, and the thorax is of a pitchy colour ; in the 

 lightest all these segments are dull pitchy red with the suture 

 still paler. 



The apical ventral segment of the male is very deeply incised, 

 the sides of the incision nearly parallel and meeting behind 

 not in an angle but in a gentle curve. 



I have taken this insect several times near Port Lincoln, and 

 I also possess a specimen of which I have no record of capture, 

 but I think it was taken in the Adelaide district.
