in such a manner tliat we may save our crops, our trees, our 

 health, and so on. If we can hold them in check to this extent 

 there is Httle use in trying to wipe them out entirely. Now 

 the Gypsy moth has already become established near Provi- 

 dence, R. I., and it seems wonderful that it has not been 

 brought into the State of Connecticut before this. Perhaps 

 it has been, but wherever it has been reported, and the matter 

 has been followed up, it has proven to be some other common 

 insect, which the people did not know, and which they thought 

 was the Gypsy moth. It is always well when we find these 

 things to submit them to some one who does know, and it is 

 always well to do that before it is published in the newspapers 

 that the Gypsy moth has been found. The Gypsy moth feeds 

 on the foliage of most all kinds of shade and fruit trees, and 

 many garden plants. 



These insects have been quite common in eastern Massa- 

 chusetts, and we have been highly fortunate that they have not 

 worked into Connecticut before this. They seem to have been 

 working northward along the coast of Massachusetts, through 

 southeastern New Hampshire and Maine, and so on into New 

 Brunswick and Nova Scotia. I think it would be well for us 

 to be on the lookout for these insects, because they may be 

 found here at any time, and the sooner we know it the better. 



Secretary Brown. I thought, Dr. Britton, you could give 

 us some general description of the difference between the ma- 

 larial mosquito and the common kinds. If you could I am sure 

 it would be very useful information. 



Prof. Britton, Those of you who observe mosquitoes can 

 tell the difference on a very little study. The malarial mos- 

 quito has wings which are spotted, and its proboscis is usually 

 more nearly in one line, one straight line, than the common 

 mosquito. When it has lived quite a while the axis of the 

 proboscis becomes more nearly perpendicular than in the com- 

 mon mosquito. The common mosquito has its proboscis 

 nearly at an angle of 45 degrees with its body, and the body is
