Biology. Unknown. Collection records indicate that this species is prevalent 

 from August through January. 



Remarks. This species is similar to bimaculata in male genital characteristics 

 but can be separated from that species by the distinctive crenulations along the 

 outer lateral margin of the apical half of the pygofer process and by the lack of 

 distinctive colour markings on the scutellum and elvtra. The crown is shorter 

 and broader in cremtlata. 



Tharra bimaculata sp. n. 



(Text-figs 459-463) 



This species comprises two subspecies which occur in the Solomon Islands and 

 New Britain. The nominate form occurs in both regions and is characterized 

 by distinctive yellow or ivory markings on the scutellum, clavus and elytra, whereas 

 T. b. vudalensis is restricted to Vudal, New Britain, and is fuscous throughout 

 except for a small subapical spot on the costa. The male genitalia are identical. 

 The forms are similar in general habitus and £ aedeagal characteristics to dorsimacula, 

 but can be separated from that species by the presence of a very narrow pygofer 

 process and a very long, narrow plate.
