22 CORYNODES ANGULICOLLIS. 



minal joints of the antennae are fuscous in C. sumatrensis , 

 and tlie sides of the thorax are but slightly deflexed. 



Colasposoma. nic/riventre , Baly. 



If I am right in referring the numerous specimens of 

 different localities contained in the present collection , to 

 Mr. Baly's species on account of the black abtlomen , the 

 insect is a most variable one in regard to size and colour 

 which latter varies from metallic green to bright aureous 

 or cupreous. 



Some varieties are aureous with the suture and a spot 

 below the base blue , other are entirely of the latter colour. 

 Some of the other species described by Mr. Baly may be 

 but varieties of one or the other forms (taking into ac- 

 count the great variability of the insects). In the present 

 one the elytra are either smooth, without transverse ru- 

 gosities (male?) or the latter are present. There is also a 

 minute tooth visible on the posterior femora (of which 

 Mr. Baly makes no mention) and the last joints of the 

 antennae are distinctly dilated.
