the liliul body not nearly so densely punctured, and Avitli 

 the base of the Gth segment black. 



The male difters from that of sapphirinus by Avanting 

 the transverse ])ilose line on the Gth segment beneath, by 

 having the liind margin of the same segment only obso- 

 letely emarginate, and by the different shape of the notch 

 of the 7th segment.

Ohs. — This species may, perhaps, ultimately prove to 

 be only a variety of X. Solskyi, from ■which it differs 

 almost solely by the dark basal portion of the 7 th segment 

 of the hind body. In the male the notch of the 7th 

 segment is deeper, and the a^deagus itself is larger than 

 in A'. Sols/ii/i ; but the former of these characters must 

 be, I think, liable to variation, for in one of the individuals 

 above mentioned the notch scarcely diflers from that of 

 X. Solskyi, and yet I can scarcely anticipate that this 

 will prove a different species, for the resemblance in other 

 respects is very great.

Much smaller than sapplurinus, with head, thorax 

 and hind body more sparingly punctured. Very close to 

 X. cyanipennis, and diftering therefrom only by being 

 considerably smaller and more slender, and by the broader 

 and less deep notch of the 7th segment in the male. I 

 have not examined the a^deagus.

 toto rufo-testaceo. Long. corp. 6 lin.

Much smaller than sappJdrinus, and readily distin- 

 guished by the beautiful violet colour of the head and
