572 NE\y SPECIES of Australian coleoptera, 



This and the two preceding species closely i^eseinble each other 

 in form, size, colour and puncturation, but may be distinguished 

 by the 2nd joint in the antennae of the males; the females appear 

 to be indistinguishable amongst themselves. They are closely 

 allied, but I do not think should be considered as one species 

 having several varieties; of each I have taken numerous specimens 

 and cannot see any variation in the 2nd joint. 



Laics femoralis, Blackb. — Of this species Mr. Blackburn 

 says : "But with the dark part of the elytra scarcely cyaneous." 

 I have two specimens which I think should be referred to this 

 species. In a male from Whitton the elytral markings are of a 

 beautiful metallic blue. A male from Sydney has the apical 

 patch of a deep violet; the basal patch is violet at its apex and 

 blue at its base. I am inclined to think that femoralis (of which 

 the 9 is unknown) is the ^ of cinclus (of which the $ is 

 unknown). I have two specimens carded together (but whether 

 obtained in cop. or not I cannot now say) of which the $ is 

 ceYtsdnly femoralis, and I cannot see any differences between the 

 9 and females identified as cAnctus by both Mr. Blackburn and; 

 myself: possibly, however, the males of both are distinct I am 

 • inclined to doubt that L. Mastersi is a synonym of cinctns; it is 

 unfortunate that both wei-e described from females. 



Laius plagiaticollis, Fairm. — M. Fairmaire records this 

 species without exact locality. I have numerous specimens, 

 including 18 males, agreeing with his description. They were 

 obtained by means of the sweep net at Pinjai-rah (W.A.). M. 

 Fairmaire remarks: " Capite {$) trifide flavo, antennarum. 

 articulo 1° inflato, apice extus angulato, 2" crasso, intus 

 bicornuto." In my .specimens one of the projections on the 2nd 

 joint is about thrice the length of the other. 



L. M A.I OR, Blackb. — There are numerous specimens of this 

 species in the Macleay Museum from King's Sound, W.A. 



L. ciNcrus, Redt. /7rt6.— Sydney, Galston, N.S.W. I have 

 also specimens of bellulus, Guer; Eyrensis,Wik\).\ und nodicorvis., 

 Blkb.
