very slight concavity of its head, and from roseocioprea by tlie 

 brighter appearance (and the transverse wrinkles on the hinder 

 part) of the same. According to Dr. G-ermar C. notulata has 

 elytral margins devoid of serration, but I do not think that 

 this is a reliable character, as specimens otherwise identical 

 differ from each other in respect of it, and I even possess a 

 specimen in which there is serration on one elytron only. The 

 sculpture of the abdominal segments is also characteristic in 

 G. obscura, consisting of fine longitudinal scratches and trans- 

 verse wrinkles, on a very brilliant surface. It resembles 

 O. acuducta, Kirby, in many respects (especially in the arrange- 

 ment of the pubescence on the elytra), but differs in the 

 absence of impressions from the thorax, smaller size, the very 

 much more finely sculptured under-surface, <fcc., &c. 



Of this species I have seen only a single specimen, which 

 occurred to me near Port Lincoln. 



C. parva, sp. nov. Sat convexa ; senea, ad cupreum colore 

 tendons ; sat nitida ; supra obscure pubescens, subtus 

 glabra ; capite sat crebre fortius punctulato, postice cur- 

 vatim rugato, medio sat f ortiter late canaliculate ; pro- 

 thorace quam longiore fere duplo latiore, antice minus 

 fortiter angustato postice leviter bisinuato utrinque bi- 

 foveolato, curvatim rugato (in medio leviter, ad latera 

 fortius), lateribus minus rotundatis, margine anteriori sat 

 fortiter rotundatim in medio producto ; elytris crebre 

 obscure sat crasse nee fortiter punctulatis, lateribus 

 postice vix evidenter serratis. Long. 2 1. 

 Yar. Colore seneo-viridi, elytris seneo-purpureis. 

 This very small Clsseis is another ally of G. notulata, Grerm., 

 and Toseocuprea, from which it may be at once distinguished 

 by the absenae of pubescent spots on the sides of the hind 

 body. Erom G. obscura, mihi, it differs in respect of its much 

 more strongly transverse thorax, which has two wide ill- 

 defined impressions on either side at the base (the outer of 

 which is the feebler of the two), the much coarser (though 

 hardly deeper) puncturation of the elytra and hind body, and 

 the much feebler serration of the hind lateral margin of the 

 elytra. The whitish pubescence on the elytra of the specimen 

 before me is very sparse and obscure (possibly owing to 

 abrasion). It seems, however, to shape itself rather after the 

 fashion of the elytral pubescence in G. ohscura. 



There is a single specimen in the South Australian Museum 

 — locality unknown ; also a single specimen of the var. (in a 

 similar plight), which apart from colour differs from the type 

 only in having the external basal impression on the thorax still 

 more feeble, and vaguely connected with the internal one. I
