the bank, when they issued from the holes burrowed by the Golletes. 

 They had doubtless fed upon the store laid up for the larvae of the 

 bees. I have found other species of Gryptophagus, as well as of 

 Anther ophagus. t in nests of Bombus muscorum, senilis, &c. This Gol- 

 letes is frequently found on the flowers of the wild tansey (Tanacetum 

 vulgare), as well as on the ragwort. Its parasite is Epeolus varie- 

 gatus, also Ghrysis ignita. It appears at the beginning of August.

Female. Length 6 lines. — Black ; densely pubescent, that on the 

 face and cheeks griseous ; the legs have fuscous pubescence above 

 and griseous beneath ; wings subhy aline, the nervures black. Ab- 

 domen ovate, with the apex acute, much less pubescent than the 

 thorax, and convex ; the apical margins of the segments fringed 

 laterally with griseous pubescence ; on the basal segment it is 

 long and rufo-fuscous, and short and blackish on the other seg- 

 ments. B.M. 



Male. Length 5-5^ lines. — Closely resembles the female, but is 

 more slender ; the face with long, dense, white pubescence. B.M. 



In 1869 the discovery of this species in England was announced in 

 the 'Entomologist's Monthly Magazine,' where it was stated that the 

 insect had been taken in the Isle of Wight by Mr. Isaac Cooke. This 

 has been subsequently discovered to be incorrect, the mistake having 

 been occasioned by some specimens being placed in the box that con- 

 tained the Isle-of- Wight captures. The Colletes was first discovered 

 by Mr. Nicholas Cooke on sand-hills near Liverpool. Subsequent to 

 1869 a number of the living bees were forwarded to me. These 

 were set at liberty on Shirley Common, in the hope of establishing a 

 colony. The year following, and again in 1876, specimens were 

 taken in the same locality.
