oviposit only in the trunk and out on the branches till they get down 

 to, say, one inch and a half in diameter. I know of trees forty feet 

 high, punctured by between two and three hundred females for their 

 egg cells, that were thoroughly treated in three hours, with no more 

 elaborate outfit than a small squirt-can oiler, and a quart of gasolene. 

 Both schemes worked all right in so far as they have been tried, and 

 up to this date no injury has resulted from using the gasolene. So, in 

 the case of valuable trees a repellant can be tried, and if ineffectual, it 

 can be followed up with a treatment of the egg cells. 



In selecting the trees that suit them the beetles choose those of 

 weakened vitality, their sense in this direction being very keen. It 

 would be hard to say why a certain tree here, and one there, is chosen, 

 but this feature is at once obvious to one following up their work. 



I am led to offer these remarks since many in charge of valuable 

 plantings have thrown up their hands in dismay over a simple matter 

 like this. Were they confronted by some of the real propositions in 

 boredom, I won't say whether they are among the lepidopters, or not, 

 there might be some excuse for despair. 



THE NORTH AMERICAN SPECIES OF LISPA 

 (DIPTERA; ANTHOMYID^).i 



By J. M. Aldrich, 

 Moscow, Idaho. 



While the Anthomyidse in general have justly acquired the reputa- 

 tion of being very difficult to classify, and at the same time highly 

 uninteresting, there are a few groups that are not only easily recog- 

 nized, but also of considerable scientific interest. If these were better 

 known, it might take the curse ofif the family ; fuller knowledge 

 would inevitably create more interest, and with a few entomologists 

 the family might become even a favorite. Hence it is very desirable 

 that such genera as are susceptible of easy definition be worked out, 

 as a beginning.

 alkaline lakes, carried on with the aid of an appropriation from the Elizabeth 

 Thompson Fund.
