tends upwards to the vertex. Thorax nearly twice as broad as 

 long; sides nearly parallel, rounded and slightly converging in 

 front ; upper surface smooth, nearly impunctate, either side just 

 within the lateral margin impressed with two large deep irregular 

 fovese, the surface of each of which is occupied by four or five 

 deep punctures ; covering nearly the whole of the disk is a large 

 irregular fusco-seneous patch, which (broad in front, and at- 

 tached to the anterior margin) narrows behind and extends 

 nearly to the basal border. Elytra slightly depressed trans- 

 versely below the shoulders ; each impressed with eleven rows 

 of fine but distinct punctures, the first short; apex of tibise 

 sometimes obscure fulvous.

Chalcolampra marmorata.

elytris punctate- striatis, infra basin foveolatis, piceo marmoratis.

Hah, Moreton Bay. 



Face deeply impressed between the insertion of the antennae ; 

 eyes black ; antennse filiform, fulvo-fuscous, joints stained with 

 piceous above. Thorax nearly twice as broad as long; sides 

 nearly straight and parallel, slightly dilated and rounded just 

 before their middle, slightly converging at the apex; anterior 

 margin concave; upper surface smooth, impunctate. Elytra 

 narrowly ovate, smooth and nitidous, regularly punctate- striate, 

 impressed below the basilar space and also on the outer disk 

 with five or six deep irregular fovese ; the piceous patches cover 

 a large portion of the surface of the disk. 



Genus Colaphus, Redtenb. 

 Colaphus Bowringii. 



C. anguste oblongus, valde convexus, aut obscure metallico-cseruleus 

 aut cupreus, nitidus ; capita rude punctate ; thorace sparsim, ad 

 latera crabrius punctate ; elytris profunda punctatis, apice sub- 

 acuminatis. 



Long. 2|-2| lin. 



Hah. Northern China. 



Head coarsely punctured ; epistome separated from the face 

 by a deep, slightly curved, transverse groove ; antennae shorter 

 than half the length of the body ; basal joints obscure piceous, 

 the rest black. Thorax rather more than one half broader than 

 long, sides rounded and slightly converging from base to apex ; , 

 disk deeply, but very sparingly, punctured, the punctures being
