■72 071 two new CoUopteroufi Insects. 



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

 but it appears to be undescribed. It is intermediate between 

 Calonota and Colymhomorpha. 



Phyllococerus purpurascens^ Hope, MS. 



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

 purpurascentibus ; corpore subtus piceo, a3neo tincto, dense albo- 

 pubescente ; elytris sat fortiter striato-piinctatis, interstitiis alter- 

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



Form of Golymhomorpha 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 irregularly 

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

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

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

 Anterior tibias slender, with an oblique incision in the middle 

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

 projecting) tooth. 



Hah. Swan River. Brit. Mus. 



COLYMBOMORPHA, Blanch. 



This genus is united to Calonota m G emvamgex ^x\di 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 Calonota it differs in having no 

 appendage to the claws. These characters have already been 

 noted by Lacordaire ; but that the males have five lamellae 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.
