116 MISCELLANEA ENTOMOLOGICA, NO, IIL 



restored Newman's genus Eutoma for the group of which Carenum 

 tinctilaticvi, Newm. is the type. In 1868, Baron de Chaudoir (1) 

 reviewed the genus Carenum as ifc then stood, criticised the work 

 done by Count Castelnau and myself, described six new species 

 and formed three new genera — Monocentrum, ConoiJterum, and 

 Carenidium. The Bai'on's paper was followed in 1869, by a fourth 

 paper from me (2) in which 21 new species were enumerated and 

 described. Since thenbutlittle has been done in this group. In 187 1 

 I described eight new species in the " Insects of Gayndah," (3) and 

 formed the genus Philoscaphus for the group of which Carenum 

 tuberculahwi is the type, and in 1873, (4) I added eight more 

 species to the list. In 1874, Bates described in the "Entomologists 

 Monthly Magazine," nine species from West Australia, including 

 a new genus, Teratidium. In 1883, I added (5) five new species 

 from Queensland, and in December 1886, the Rev. T. Black- 

 burn (6) described two South Australian species of the genus 

 Euryscafhus. 



This makes the number of species in all 180, including a few 

 ■which have accumulated in my collection since I last wrote on the 

 subject, and which I describe further on. 



My object in now reverting to this old and favourite subject, is 

 because I find that the enormous increase in the number of the species 

 of the group has so outgrown the old tabular arrangement of them 

 which I made more than 20 years ago, that a fresh arrangement and 

 classification has become very desirable if not necessary. I have 

 been compelled in my efibrt to make my revision of the group as 

 distinct and intelligible as it is in my power to make it, to add 

 considerably to the number of genera, so that by my present pro- 

 posed arrangement the genus Carenum of Bonelli, yields material 

 for 14 genera. My definition of these, given below, is shoi't
