ENTOMOLOGICAL NOTES. 499 



Calioxys is a parasite upon M. circumcincta', and I think, 

 likewise, upon M. Willughbiella. It is right however to state, 

 that I had cocoons of one other species of bee {Osmia atri- 

 capllla, on the habits of which I have some remarks to make 

 at some future period), but it must be stated that I never 

 observed the Ccelioxys go near the nests of that species, which 

 are always found in quite a different situation.

This beautiful insect has, at first sight, so exactly the 

 appearance of a large Leistus or Nebria, that I at once sup- 

 posed it intermediate between those genera and Calosoma. 

 A second glance, however, and an examination of its mouth, 

 prove this idea to be wholly erroneous, and point out its 

 relationship to the genera Anthia and Graphiptems ; and 

 it is between these and Catascopus of Kirby that it must
