Tb > dark markings on the elytra are moderately sharply definpd 

 and probably variable. In the type they consist of (a) a common 

 mark on the hinder half roughly resembling the letter T, (h) a 

 tra- IS tersely quadrate blotch just touching the upper extremity 

 of eg ch arm of the T and reaching the lateral margin, (c) a 

 subh' meral blotch similar to (6) which from each extremity emits 

 a narrow branch connecting with the corresponding extremities 

 of (6). Compared with the European D. lunatus, Fab., this 

 species is much smaller, with the antennae a little longer and less 

 stout, the surface evidently more nitid, the sculpture not much 

 differing but with the sublateral carina of the pronotum a little 

 nearer to the lateral margin and the rows of punctures on the 

 elytra placed in shallower strife, and the colors and markings very 

 different. 



Victoria (under bark of Eucalyptus ; Dividing Range). 



DIPLOCCELUS. 



D. [TriyliyUus) fasciatus, Macl. Mr. Lea has been good 

 enough to send me an example of this insect compared with the 

 type. It agrees well with the description and is certainly a 

 JDiplocceluH. This correction has not to my knowledge been pre- 

 viously noted definitely, although Mr. Lea in one of his papers 

 mentions D. fasciafus — without an author's name — and thereby 

 probably indicates his knowledge that Macleay's species is a 

 Diplocoelus. 



D. ovatus, MacL, piliyer, Reitt., and punctaUis, Lea, must be 

 extremely close inter se and are probably identical. Macleay's 

 is the earliest of the names. Reitter says that he has not seen 

 Macleay's description, and Lea does not refer to either ovatus or 

 piliger. They all describe a species notable for its long erect 

 pubescence and strongly punctulate-striate elytra. I cannot find 

 anything in the descriptions inconsistent with their being all one 

 species, although if that be the case Macleay described a very 

 small specimen — yet not indicative of much greater variation in 

 size than I find in _D. angustulus^ Blackb. Reitter thinks that the 

 name ^'ovatus" is inconsistent with identity with his species, 

 which is "ovalis" in form — but on referring to the description I 

 find that Macleay gives the form as " oval " in spite of the name. 

 These insects — whatever number of species they represent — all 

 differ from the other described Australian Diplocceli as follows: — 

 from fasciatus, Macl., by their unicolorous elytra ; from Leai^ 

 Blackb., by their very much smaller size ; from angustulusy 

 Blackb., by their much less narrow and less parallel form ; and 

 from exiguus, Blackb., and the new species described below by 

 their much stronger elytral sculpture and longer pubescence, Mr.. 

 Lea has kindly given me a specimen of his D. punctatus ; the 

 other two — if they are distinct from it — I have not seen.
