Living Mantrps.—Mr. R. Stenron exhibited some living 
Mantids, bred at the Ministry of Agriculture Pathological 
Laboratory, Harpenden. The egg-case had been taken 
by Mr. J. C. F. Fryer from a dwarf Japanese maple imported 
during the winter of 1920-1921. The eggs hatched in two 
batches, the first about June 9th and the second on June 16th.

and later upon blow flies. They were kept in a cold green- 
house and attained the adult stage, a 9 on 10th Oct. and
