We have already remarked on the unsatisfactory state of this 
genus; as justly observed by Mr. Marshall it appears to be 
merely ‘‘a receptacle for all species (of Cryptides), however 
dissimilar, which have an imperfect areolet” (Knt. Ann., 1874, 
p- 123). Gravenhorst described fifty-seven species under this 
genus in his ‘Ichneumonologia Europea,’ but only ten in both 
sexes; ‘laschenberg described about the same number, several of 
which are new, still only fourteen in both sexes; Ratzeburg 
describes a few more; and, with a few other scattered notices and 
descriptions, this appears to be all that has been done with the 
genus. It is one, no doubt, very rich in species as it stands, and 
much in want of careful revision. Foerster, in his ‘ Synopsis,’ 
split this genus into seventy-two other elaborate genera, but as 
he has given no types of these, or described the species included 
in them, they are but of little assistance, the number of his 
genera being about equal to the number of described European
