CIMBEX ANNULATA. Leach. 

 ? (Female.) 



In the third volume of the Zoological Miscellany, 

 published in 1817, Dr. Leach has given an excellent 

 monograph on the species of this genus ; all of which 

 are rare. At this period, he possessed but one speci- 

 men of this species, a female, taken near Windsor, 

 by Mr. Griesbach. When the Doctor was last in 

 England, he brought from Devonshire six males and 

 four female specimens — they were found at one spot, 

 we believe, near Ashburton, by a person who was in 

 the habit of collecting specimens for him. With his 

 usual liberality he presented to the British Museum 

 five specimens — to myself four — and to Mr. Stevens 

 one, a female. The Cirabices appear in the perfect 

 state the latter end of April ; also in the months of 

 May, June and July they are very sluggish, and, if 

 beaten into the net, simulate death. They are generally 

 found in open places, and on the skirts of woods. 

 The caterpillars of the respective species feed on 

 leaves, generally on those of shrubs and trees. Upon 

 the branches of these the parent fly deposits her eggs 

 in cells symmetrically arranged ; and the instrument 

 with which she forms them is a saw, somewhat like 

 ours, but far more ingenious and perfect, being 

 toothed on each side, or rather consisting of two dis- 

 tinct saws, with their backs (the teeth or serratures 

 of which arc themselves often serrated, and the ex-
