to tiud 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 Kiver 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 .">, and again on June Ul, while they 

 were quite abundant near Cleveland, June 23, on the heads of timothy. 



An invasion of the pear-tree blister-beetle {Pomphopcva cenea Say) 

 occurred in central eastern Ohio, the i)est appearing suddenly on pear 

 trees in great numbers, eating oft" 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 Saj") was 

 also in Licking County, eating out the blossom buds of a species of 

 Oemn, either rivale L. or alhnm Gmel,, usually two beetles being found 

 on each plant. 



No serious ravages of the four-lined plant-bug {Fcecilocopsus Uneatus 

 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-
