pilations to a large extent, especially in the case of the Blackberry and 

 Raspberry pests. The bulletins are good, and are extremely useful to 

 entomologists; but there is just a question whether it is the best plan to 

 issue as a Station Bulletin a work treating of insects which have not been, 

 and in some cases never will be injurious in the territory embraced by the 

 State for which the Report is issued. The average farmer wants to know> 

 and quite naturally, what to do with the pests that are troublesome in his 

 land, and will not wade through a large pamphlet the bulk of which does 

 not concern him. We all have our ideas of the proper, and Mr. Webster 

 may be nearer right than I am, but I certainly would not have included 

 Grapta comma among the injurious Blackberry insects on the faith of a 

 single larva and one chrysalis found on vines in the woods. Complications 

 of this character have an undoubted value; but they are really adapted 

 for general works like that of Mr. Saunders, on Fruit Insects, rather than 

 for Station Bulletins. 



The Bulletin on Wheat Insects is of much more vital interest to the 

 farmers of Ohio, and Mr. Webster speaks with more positive knowledge 

 on this subject. It is the underground pests that are specially considered, 

 and this brings me to another repetition of the experience of the New 

 Jersey farmers, that where they have used the commercial fertilizers, there 

 insects of this character do not trouble them. One of the largest growers 

 of Onion sets in the State told me recently that he never had the slightest 

 trouble with the Onion maggots so long as he did not use the barnyard 

 manure, and that he had become so firmly convinced of the value of these 

 chemical manures as insecticides that he used them exclusively. This is 

 one of the men that really make farming pay, and his experience is sug- 

 gestive. 



Colorado Insects.— Some of these are treated in Bulletin No. 19 of the 

 Colorado Station by Mr. Gillette, and the Bulletin shows that its author 

 has not forgotten how to do good work. Quite a variety of species are 

 treated, none of which call for special comment, save to suggest that tig.. 

 9, of Trypeta canadensis, would look a little better if it had legs. We 

 have always been under the impression that all insects had some legs, 

 though in some collections the matter is left in doubt, and in figures, the 

 Lepidoptera seldom have more than two. Mr. Gillette recommends the 

 application of arsenites as a remedy for two species of leaf rollers that he 

 has found injurious. 



The Squash Lady Bird.— For some years Epilachne borealis has become 

 steadily more abundant in the Eastern States, and has in some localities 

 become a serious pest on Cucurbs of all kinds. In New Jersey it seems 

 to have been more troublesome on the Watermelon than on others of the 

 vines, but I have found it abundant on Pumpkins, Squashes, Melons and 

 Cucumbers as well. In the April number of the News I figured the 

 mouth parts of this species in comparison with those of Coccinella 9- 

 noiaia, to show the differences in the mandibular structure more particu-
