various situations sucJi delicate sustenance as honey and pollen collected from 

 flowers, instead of animal food, as in the most of the Pvaedones. 



These Bees are all '■'■solitary consisting of male and female only, with 

 the exception of the last three genera which are '■'■social.'' As in the 

 Praedones, many solitary " species form large colonies of separate burrows in 

 close proximity . 



COLLETES. 



These insects burrow, frequently in large colonies, either in sandy 

 banks (C. daviesana and cunicularia), in the softer parts of walls, or 

 similar situations. Their little tunnels are usually 8 to 10 inches long, 

 plastered inside, and enclosing a series of cells made of a delicate and 

 glistening membrane; each cell contains an egg and sufficient honey 

 and pollen for the nourishment of the future grub. 

 CoLLETES, Latr. 



succincta, Linn. — Delamere, B.C. 



fodiens, Kirb. — Southport B.C. 



marginata, Sm. — balteata, Nyl., Thoms. — Wallasey, H.H.H. 



Daviesana, Sm. — Mersey banks near Manchester, J.R.H. ; 

 burrows in sandstone rock, Wallasey, J.T.G. 



cunicularia, Linn. — This is one of the specially interesting Bees 

 of our district, the species being peculiar to it, as far as the 

 British Islands are concerned. The species was first taken at 

 Wallasey on May 4th, 1855, by the Rev. H. H. Higgins, but 

 was not then recorded by him. In i86g the msect was taken 

 at the same place by Mr. Nicholas Cooke, and recorded by him 

 in the " Entomologist's Monthly Magazine," p. 276, (1868-9), 

 and in the "Entomologist's Annual," for 1870. It has since 

 been taken freely in the same locality, B.C., H.H.H., E.C.T., 

 J.T.G. , R.N., W.G. The species has also been taken 

 occasionally at other places in our district besides its 

 "metropolis" at Wallasey, as at Southport, B.C.; in some 

 numbers on the Waterloo Coursing Ground, near Liverpool, 

 J.R.H. ; abundantly at Crosby, R.N. ; one specimen at Blackpool 

 by Mr. C. E. Stott, one at Rock Ferry, J.T.G., and one at 

 Chester, E.C.T. ; so it is evidently more widely distributed 

 than was at first supposed.
