men given an outline of the various 

 ■BBfl at which beetles may be had, 

 md the various means for taking 

 hem. We have said nothing about 

 jreeding them, for it is little resorted 

 o, as "bred" coleoptera are generally 

 >mall, and poorly colored, compared 

 with captured specimens. Little is 

 mown of the early stages of very 

 j many species, and "life histories"' are 

 reatly needed. We would refer our 

 eaders to our last volume, page 184, 

 ■ a model "Life History*' of a Beetle 

 rom the pen of our esteemed corres- 

 ondent, Mr. C, H. H. Walker, of 

 Iverpool. We should be pleased to 

 have others.

TO CORRESPONDENTS. 



Dr. Ellis writes : "I wish your readers would 

 send more notices of captures ; I believe 

 they are very useful ; and as Mr. Gregson 

 says. ' it is the readers who make a period- 

 ical.' " 



. H P., Liverpool. — There are so many 

 kinds of Beetles that it is impossible to 

 name yours from the descriptions you give. 

 They may not be beetles at all. 



BRITISH BIRDS; THEIR 

 NESTS AND EGGS. 



By S. L. Moslev. 



Genus V. Pernis, Cuv 



Pernis. — Perm's (L), — a Bird of Prey; 

 Buzzard. 



This genus may be distinguished from the 

 last by the absence of the bare or bristly space 

 around the eye, the front of the head being 

 covered with small thick-set scale-like 

 feathers ; the leg is feathered a little below 

 the knee. Only one species occurs in Britain 

 as a summer visitant, occasionally remaining 

 to breed.
