Long. 6 "5 mm. 



Hab. PenANG. 



Of this also we have only a single male example, which 

 was found by the late Mr. Lamb. The hinder part of the 

 body is not so much reduced, nor the head proportionally 

 so large, as in the previous species, and the insect is 

 altogether smaller, but it is closely allied notwithstanding. 

 The coloration is analogous, but the thorax has five 

 black patches upon a reddish ground. The pubescence 

 with which the whole surface is clothed is very coarse and 

 the scutellum is rather less large in proportion than that 

 of 0. maciUijjennis. The stridulating appendages are of 

 similar form but without the short terminal processes.
