There is some doubt respecting the position of this genus, 

 which, except for its large contiguous eyes, not covered by the 

 ocular lobes in repose, I should have placed with Crypto- 

 rhynchinaj ; but, assuming it to be a Zygopine, it would, ac- 

 cording to Lacordaire's arrangement, take its place with the 

 New-World forms, owing to the breadth of the metathoracic 

 episterna conjointly with the presence of a pectoral canal and 

 a seven-jointed funiculus. For the present I place it after 

 Sphadasmus, partly on account of the eyes not occupying the 

 whole of the head, and partly because it leads to Symjnezojyus^ 

 which has a deep pectoral canal. The remarkable insect de- 

 scribed below is closely covered above with black oj)aque 

 spots, in the middle of each of which is a little shining gra- 

 nule : the effect of these among the pm"e grey scales is to give 

 the upper sm'face an ashy colour ; the under part is of a pure 

 ivory-white.
