Distinct from ocellaris, Fall., by the shape of the hemelytra, which 

 are regularly rounded, not truncate, at tlie apex ; by the different 

 arrangement of the ocollated spots, by the proportions of the vertex, 

 and a different facies. The pearly white upper surface contrasts 

 strongly with the broad black transverse fasci», and in certain lights is 

 brilliantl}^ iridescent. I took a single specimen of this beautiful species 

 in a wood near Leicester, in August, 1864. Nothing like it seems to 

 have been described, nor have I seen a similar form in any collection. 



* A figure of this species will appear in No. 23.
