MR. NEWPORT'S OBSERVATIONS ON THE GENUS ANTHOPHORABIA. 83 



From the circumstance that each parasite was attached to the surface of the bee, and 

 fed upon it from without, like the larva of Monodontomerus, it was evident that the female 

 does not insinuate her eggs into the body of the bee, but merely attaches them to its skin ; 

 while from the circumstance of nearly the whole of the females I had confined in the tube 

 having escaped by insinuating themselves between the sides of the cork and the glass, and 

 forcing their way through chinks which appeared much too small to admit of their passage, 

 there seems reason to think that the usual habit of this species may be to penetrate into 

 the cell of Anthophora after it has been closed, and deposit her eggs c# the nearly full- 

 grown inmate. This supposition is further countenanced by the acute and denticulated 

 form of the mandibles of the female, and by the absence of an exserted ovipositor, which 

 structure would perhaps be necessary under other circumstances. Further, also, that the 

 bee is infested not by a few, but by an abundance, — a whole brood of these creatures, — 

 which entirely destroy it. 



I have allowed my bee-larva, with its parasites, to remain in a cold room up to the 

 present time, but the latter have scarcely at all increased in size, and yet they remain 

 firmly attached to their victim, appearing scarcely even to vegetate. 



This is precisely the condition in which the bee itself remains during winter ; both that 

 and its parasites requiring a high temperature of the sand-bank, heated by the sun's rays, 

 for their evolution.
