290 THE CANADIAN ENTOMOI,OGIST. 



The material in my possession at present does not warrant my giving 

 exact measurements. Faxon's figures sliow that the abdomen is shorter 

 and broader than that of var. homifiis, and slightly less than two-thirds of 

 the entire length. The form is more like that of var. canis, and I should 

 not be at all surprised if a study of fresh material would result in the 

 conclusion that var. bovis is simply a diminutive form of var. canis, and 

 that the cattle originally became infected from contact with dogs. This 

 is, however, mere speculation. 



8. D.f. var. suis^^D. phyHoides, Csokor, 1878. 



Fe?nale : 0.24-0.26 by 0.06-0.066 



Male : 0.22 by 0.05-0.057 



Hexapode larva : o. 1 3-0. 1 4 long. 



Odopode larva : 0.22-0.28 long. 



Ovum : o. lo-o. 1 1 by 0.034 



rostrum + cephalothorax=about one-half the length of the 

 body. 



As I stated in the discussion, in answer to a question, this form is 

 totally different from var. bovis, having an extremely pointed abdomen. It 

 is so different, in fact, that Csokor described it as a new species ; most 

 authors admit it only as a variety. Personally, however, I rather incline 

 towards Csokor's opinion. 



NOTES ON THE BEAN WEEVIL.* 



Professor Riley gave some verbal notes on the above subject, covering 

 substantially the facts in articles recently published in the Canadian 

 Entomologist, and an editorial prepared for the first number of 

 Volume v., Insect Life.\ Both the Bean Weevil and the Pea Weevil 

 were found to have temporary thoracic legs of a peculiar form in the 

 post-embryonic larval state, and also certain prominent spines on the 

 prothoracic shield. The eggs of the Bean Weevil in tlie field are not 

 attached to the outside of the pod, as had hitherto been stated and believed, 

 but are laid in masses within the pod, through an aperture made by the 

 jaws. In the green pods this aperture must frequently close up, so as not 

 to be noticeable, as pods which were brought in from the field showing
