near the surface of the earth ; it appears to me that they prefer 

 naked caterpillars, and probably puncture them after they 

 have descended into the earth, but before they have changed 

 into chrysalides. 



The following list of British species belonging to this nu- 

 merous genus, incomplete as it is, will enable any one to re- 

 cognize those insects which belong to this particular group; 

 and manuscript names without descriptions would only be an 

 incumbrance, since Professor Gravenhorst is about to publish 

 a Monograph upon the family.

I. Atropos has been bred from the caterpillar of Acherontia 

 Atropos {pi. 147), by Miss Giraud of Faversham, Kent; the 

 specimen figured from Mr. Sulivan's cabinet was taken at 

 Rochester by Professor Henslow; and Mr. Davis took his the 

 end of July in a lane leading to Darent Wood. 



For specimens of Juncus liyiiger. With., Luzula congesta, 

 Forst. (Flaxen Rush), I am indebted to Mr. Charlwood.
