228 PROCEEDINGS OF THE ACADEMY OP 



spot, covering the clavus, reaching to the subcostal nervure and extending two- 

 thirds of its length, when it becomes blacker, and ramifies broadly against the 

 lateral margin, a much narrower branch also continues against the posterior mar- 

 gin; membrane fuliginous, some of the nervures tinged with testaceous, towards 

 the base ; wings pale fuliginous, nervures darker ; tergum with two pale spots 

 upon the lateral margin ; femorae black, their basal third and trochanters tes- 

 taceous, tibiae light-piceous, black at tip, tarsi dusky at tip. 



Length 11 millim. 9- Takanosima, Japan. 



Nothing is said of the antennae, as they are unfortunately broken off from 

 the only specimen obtained. 



A specimen, which I take to be a variety of this species, was captured at the 

 Cape of Good Hope. 



It differs from the type in having the posterior thoracic lobe tnarmorated 

 with testaceous, the hemelytral spot is not so black, spreading more irregularly 

 over the surface, the testaceous color is faintly spread over the margins of the 

 tergum, the femora? are testaceous for two-thirds of their basal length, the 

 tibia and tarsi are almost entirely testaceous, and the rostrum is tinged with 

 piceous, more or less deep, throughout its entire length. Its length is 10J mil- 

 lim. 9. 



It corresponds with what is considered as a not full colored state of many 

 insects of this and other families of Hemiptera, wherein the insect has not 

 lived long enough to attain its complete depth of coloring, or where certain 

 physical contingencies have retarded its attainment to full perfection of color.
