136 ENTOMOLOGICAL NEWS. [May 



In 1892 it was reported to me as abundant, in the larval stage, at 

 Perry, Lake county, northeastern Ohio, and during the same year 

 Mr. Charles Dury collected the beetles near Cincinnati, nearly in the 

 extreme southwestern part of the State. The stomach of a crow 

 shot in Michigan, also in ,1892, contained an adult of this species, 

 but it was known to have been first introduced into this latter State 

 by a lady, who unknowingly and unintentionally brought it in her 

 trunk from some of the more eastern States, where she had been 

 spending the summer. Mr. Hine found it the following year in 

 the northwestern part of Ohio, but it must have spread less rapidly 

 to the south, as it was not until 1893 that it made its first appear- 

 ance at Wooster, about fifty miles from localities where it had oc- 

 curred in great abundance two years earlier. Specimens now began 

 to be received from localities along the Ohio river throughout its 

 entire length in this State, some of these localities being situated 

 at a considerable distance away from the river, especially in the 

 southwestern part of the State, and it was plainly to be seen that 

 the Phytonomus was spreading toward the centre from all points 

 of the compass except the west. The late Dr. Kellicott reported its 

 first discovery at Columbus in 1895, and there was yet a limited 

 section to the west of this that was not known to be infested. In view 

 of all the' data at hand it seems clear that Phytonomus punctatus 

 spread westward from New York, through western Pennsylvania 

 and northeastern Ohio, and was here washed into some or all of the 

 tributaries of the Ohio river in this region during high waters, and 

 carried down stream, probably clinging to drift wood and other 

 debris. This drift was often carried by back waters far back into 

 the country, and with the receding of the waters left not only high 

 and dry, but often in the midst of clover fields. As I have found 

 the sexes pairing in autumn, it is not unlikely that more or less 

 females are thus fertilized in the fall, and if carried down stream, 

 however isolated they might ultimately find themselves, they would 

 be able to start a colony in the adjacent clover fields, and their pro- 

 geny would spread still farther inland. At the time I observed the 

 species at Chautauqua Lake, New York, the adults were floating 

 about in the waters of the lake, seemingly little, if at all, affected by 

 their bath. 



Hylastes trifolfi doubtless spi'ead from nearly the same locality 

 in New York, and so far as my information extends followed almost 

 precisely the same course, though its diffusion, except so far as this 

 was due to being carried down the Ohio river, was slightly less 

 rapid. It was first observed in northeastern Ohio, though it proba- 

 bly preceded Phyloiioimts by several years, and spread westward, 

 and seemingly less rapidly to the southward. While its pi-ogress 

 across the northern part of the State, where it also attacked peas as 

 well as clover, was being noted, my source of information being 

 largely reports, accompanied by specimens from farmers, one of 

 these reports was unexpectedly received from southeastern Indiana,
