820 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



specimens), which came from Australia. I have met with a 

 species which agrees very fairly with Captain Broun's description, 

 and as the insect has not yet been described in any Australian 

 publication, the following will probably be of interest to Austra- 

 lian readers. I may add that I can discover only eight joints in 

 the antennro of this and the two following s})ecies, which would 

 associate them with P. ceneAis, Germ., a species for which Dr. 

 Sharp has pointed out in the Ent. M. Mag. (Vol. xxi., p. 112), that 

 a new generic name may be necessary oa account of this character. 

 It should be noted also that the two species I have named Lindi 

 and sublineatus will probably eventually be considered generically 

 distinct from all their allies yet described, since they differ from 

 Paracymus in the tendency of the elytral puncturation to run in 

 rows, in the absence of a prosternal keel, and in the shape of the 

 mesosternal keel, which is very peculiar indeed ; on the front half 

 of the mesosternum it is non-existent, but iu the hinder (almost 

 perpendicular) portion the external margin seems to be formed by 

 a keel which also runs round the rather wide base, and emits from 

 the middle of the latter a central keel which runs forward (down 

 the declivity of the mesosternum) for a short distance. Hence, 

 viewed from above the mesosternum seems to rise from the general 

 surface (not as in Paracymus as a sharp point, but) in the form 

 of a transverse ridge, which (on account of the convexity of the 

 mesosternum) is of a curved shape, its convex side being turned 

 forward. The general resemblance to Anaccena as well as the 

 inclination towards that genus of the structural peculiarities sug- 

 gests the probability that other forms intermediate between 

 Paracymus and Anaccena may yet be discovered ; I therefore 

 think it better for the present to regard these insects as forming 

 merely a section of Paracymus ; to which for convenience of 

 reference the name Paranaccena might suitably be applied.
