Resembles E. ctneipe^mis, Waterh. ; compared with that spe- 

 cies the general form is less elongate, and the elytra are more 

 narrowed hindward. The elytra are much more coarsely punctu- 

 late, and the lamelliform processes of the antennal joints are 

 much shorter, that of the third joint being scarcely longer than 

 the fourth joint, those of the following joints increasing a little, 

 but not one of them exceeding double the length of the joint from 

 which it is given ofl'. 



Victoria ; in the mountainous districts near Tarwin River in 

 South Gippsland. Sent to me by Mr. C. French, and named (at 

 his wish) in honor of the captor, Mr. Ross. 



CERAMBYX PULLUS, Newm. 



I believe this name to have crept into Masters' " Catalogue of 

 Australian Coleoptera" by an oversight. Newman states that it 

 is from New Zealand.

 cens ; prothorace ad latera obtuse tuberculato, supra crasse 

 rugato ; elytris apice emarginatis, incisur?e angulis productis 

 spiniformibus; subtus oculis sat approximatis, spatio inter 

 oculos fortiter sat aequaliter punctulato vix leviter impresso

The species of this genus are very difficult to separate inter se 



owing to the sculpture and pubescence of their upper surface being 



very uniform. The present species is very like P. serious, Newm., 



from w^hich it differs by the antennae of the male having their 



dilated joints more strongly swollen and ditierently proportioned, 



and notably by the structure of the head, which appears to me to 



furnish the best specific characters in this genus. The eyes are a 



trifle more approximate above than in P. serious, the interval 



between them being distinctly less wide in the male than the
