2 . A handsome black insect, \vith the legs and apical margijis 

 of the abdominal segments iiavous, the hind coxa) and femora red,

The sculpture is identical in both sexes, and I cannot conceive 

 how Cameron failed to associate them. 



Prom an examination of the iigure of the female {loc. cit.) I 

 was at first of the opinion that it was synonymous with my 

 Ereristes aJhicincta ; but there are several pertinent points of 

 distinction : — The edge of the pronotum is wliite, tiie abdominal 

 bands are laterally fulvescent, the hind coxse except below are red, 

 the areolet is elongately petiolate, with the pedicle " as long as the 

 branch of the first transverse cubital nervure," the face is centrally 

 carinate, the apex of the clypeus is brunneous, the metanotal 

 pilosity is more fulvous than that of the remainder of the thorax, 

 the metapleurjB below the lateral carinas are smooth, and, above 

 all, the abdomen is closely punctate and the terebra, in proportion 

 to the length of the body, decidedly shorter. Strangely enough 

 the areolet is figured by Cameron as distinctly sessile, and the 

 nervellus is not shown. 



Mr. Green has been so good as to send me many specimens of 

 this handsome species, the colouring of which is remarkably con- 

 stant. Our oldest record of the insect is a female, in the Oxford 

 Museum, taken by Thwaites in Ceylon in 1873.
