There is some doubt respecting the position of this genus, 

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

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

 rhynchinffi ; but, assuming it to 1)C a Zygopine, it would, ac- 

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

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

 epistcrna conjointly with the presence of a pectoral canal and 

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

 Splindas7nus, partly on account of the eyes not occupying the 

 whole of the head, and })artly because it leads to Syvipiezojnis^ 

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

 scribed below is closely covered above with black opaque 

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

 nule : the effect of these among the pure grey scales is to give 

 the u])per surface an ashy colour ; tlic under part is of a pure 

 ivory-white.
