NEOCHx\RIS Fü'LVICOLLIS. 57 



the allied genera of Platyxanthinae by the deformed di- 

 lated third joint of the antennae. All the specimens 

 contained in the Sumatran collection, obtained at Soeugei- 

 Simauoeng , Moeara Laboe , Loeboe Gedang , Palembang and 

 Soeroelangoen , differ in colour from the typical forms 

 contained in my collection and prove the insect to be 

 very variable in that respect. As I suspected at the 

 time of publication, the females, of which many speci- 

 mens are now before me , differ from the male insects in 

 having simple antennae, in which character they agree 

 with the same sex in the genus Dorydea. From the female 

 in the latter, the same sex of the present insect may be 

 separated by the longer third joint of the antennae which 

 is the longest of all, by the more squareshaped thorax 

 and by the different punctuation of the elytra , which are 

 very finely and irregularly punctured in the female sex. 



I may add here to my former description that the third 



joint of the antennae in the male is deeply excavated on 



its upper surface and slightly indented at its inner margin. 



I give here the colours of the typical form , and of the 



varieties from Sumatra : 



Below black. Head , thorax , antennae and femora ful- 

 vous. Elytra greenish and bluish black, the apex fulvous 

 (typical form). 



var. a. Elytra with a transverse testaceous dentate band 

 before the middle. Tibiae more or less marked 

 with blackish, 

 var. h. Elytra fulvous , a narrow transverse basal band , 

 another one below the middle , the lateral 

 margin at the same place and the apex bluish 

 black, 

 var. c. Below fulvous , antennae testaceous , 'stained with 



fuscous , elytra entirely black, 

 var. d. Below black , elytra bluish black , a transverse 



band at the middle fulvous. 

 Between all these forms , several intermediate stages are 

 to be found as well.
