72 Oyi two neio Coleopterous Insects. 



This genus is founded on a well-knoAvn Australian insect, 

 but it appears to be undeseribed. It is intermediate between 

 (Jalonota and Colymbomorplia, 



Phyllococerus ])urpurascenSj Hope, MS. 



Ovalis, convexus, nitidus : capite thoraceque viridibus ; elytris griseo- 

 purpui'ascentibus ; corpore subtus piceo, aeneo tincto, dense albo- 

 pubescente ; elytris sat fortiter striate -punctatis, interstitiis alter- 

 natim seriatim punctatis. Long. 6 lin., lat. 3i lin. 



Form of ColymhomorpJia lineata, but more regularly oval 

 and more convex ; very shining. Clypeus thickly and mo- 

 derately strongly punctured, narrowed in front, triangularly 

 notched in the middle. Thorax not very thickly and some- 

 what obscurely punctured. Scutellum green, obscurely punc- 

 tured. Elytra greyish purple, somewhat strongly striate- 

 punctate : the interstices not convex ; the first in*egularly 

 and somewhat strongly punctured ; the third, fifth, and seventh 

 each with an iiTegular row of punctures ; the second, fourth, 

 and sixth are rather narrower. Club of the antennae black. 

 Anterior tibise slender, with an oblique incision in the middle 

 of the outer edge, surmounted by a somewhat acute (but not 

 projecting) tooth.

CoLYMBOMORPHA, Blanch. 



This genus is united to CaJonota in Gemminger and Harold's 

 Catalogue. I think it should certainly be kept distinct. It 

 differs from both the foregoing genera in being hirsute above, 

 and in having the mesosternal projection in the foim of a 

 blade instead of conical ; from CaJonota it differs in having no 

 appendage to the claws. These characters have already been 

 noted by Lacordaire ; but that the males have five lamellse to 

 the nine-jointed antenna seems to have been entirely over- 

 looked. 



In the British-Museum collection there are three or four 

 specimens, which differ considerably in colour and sculpture 

 from each other and from the type of the genus, C. lineata ; 

 but I cannot satisfy myself that they are more than varieties, 

 as there appear to be intermediates.
