THE CANADIAN ENTOMOLOGIST. 31 



develops in the cells of Anthophora. By means of its tarsal claws and of 

 a pair of pre-anal spinnerets and ciaspers, it holds on very tenaciously to 

 the hairs of the bee, and is carried on the same into the bee-burrow. 

 When the bee-egg is laid, and before the cell is capped over, this triungulin 

 disengages itself from the bee, and at once pounces upon the bee-egg. 

 After having sucked the contents of this last, it throws off the triungulin 

 skin and assumes the Carabidoid stage ; thereafter it feeds upon the 

 honey-paste stored by the bee, and, within the cell, goes through all the 

 hyper-metamorphoses characteristic of the family. All the later stages, 

 however, take place within the puffed skin of the Scarabceidoid larva, the 

 Coarctate larva being well separated therefrom, but the third or final larva 

 having such a delicate skin that it is not easily separated from this last 

 when shed. There is but one brood annually, the pupa state being attained 

 in August, and the beetle maturing all its parts during the autumn, and 

 lying within its numerous coverings until the following May. 



The paper contains some interesting details as to the effects of rain 

 both on the bee-larva and the Homia larva ; on the vicissitudes that 

 befall the triungulin, its fratricidal propensities when two cr more are 

 enclosed in the same cell, and on its adaptability to food supply.

EGG— Globular, smooth under a low power, but under a high one, 

 seen to be reticulated in irregular hexagons, the ridges flat and broad, and 

 having at the bottom of each depression a white point ; color yellow- 

 green. Duration of this, stage in August 3 days, in October 6, in April 

 6. The egg is laid on grass, which is the larval food plant. 



YOUNG LARVA— Length .12 inch ; cylindrical, a little thickest in 

 middle, tapering slightly both ways from 8th segment, and ending in two 

 divergent tails, each of which is thick at base and round, tapers to a blunt
