to find a living worm, though there were an abundance of dead ones. 
This simply coincides with my own observations, and notwithstanding 
what has been said in regard to the value of parasites to the farmer, 
this one has this year saved the farmers of Ohio several hundred thou 
sand dollars, and though I expect to see this clover pest reach, if not 
cross, the Mississippi Eiver next year, there is little doubt but that this 
fungoid enemy will not only overcome it on its first appearance in any 
locality, but keep it under control in the future. I observed adult Phy- 
tonomus, about Wooster, up to May 3, and again on June 21, while they 
were quite abundant near Cleveland, June 23, on the heads of timothy. 
An invasion of the pear-tree blister-beetle (Pomphopwa cenea Say) 
occurred in central eastern Ohio, the pest appearing suddenly on pear 
trees in great numbers, eating off the bloom and very young fruit. In 
a few days they disappeared as suddenly as they came. Mr. Dury, of 
Cincinnati, tells me that he secured his only specimens, one from the 
crop and the other from the bill of a bird shot in the high top of a maple 
tree, where it was evidently feeding on the beetles when death suddenly 
ended the repast. 
The joint worm (Isosoma hordei Harris) must have been excessively 
abundant in the northern portion of the State last year, as I found the 
adults in myriads in a field, in Huron County, on May 11, apparently 
just issuing from last year's straw, left in the field. 
The bean leaf-beetle (Cerotoma caminea Fab.), which I have else- 
where* recorded as feeding on the foliage of the bean in Indiana, and 
both this and the cowpea in Louisiana, was found working a similar 
mischief in the southern part of Ohio, in May, while a few days later 
they were observed in the woods in Licking County, feeding on the 
foliage of a species of Desmodium which, in the north at least, is proba- 
bly their natural food plant. 
The well-known raspberry fruit-beetle (Byturus unicolor Say) was 
also in Licking County, eating out the blossom buds of a species of 
Geum, either rivale L. or album Gmel., usually two beetles being found 
on each plant. 
No serious ravages of the four- lined plant-bug (Poecilocapsus lineatus 
Fab.) on the currant have been reported this year, though they were 
working to some extent in Ashtabula County, where they last year 
exhibited a partiality for the grape varieties, while this season no such 
selection was apparent. Adults and young were observed here on June 
9. Just a week earlier, in Licking County, the pest was literally swarm- 
ing, not only in the woods but in the fields and along the roadsides, 
seemingly almost omnivorous, so far as food plants were concerned, 
catnip, dock, sweet clover, and numbers of other plants and shrubs 
exhibiting the marks of their depredations. 
Once or twice only have I read of a dipterous enemy of growing 
beans, and had supposed that the single species, Anthomyia angusti-
