sooner or later confront the entomologist who studies life in 

 living objects. The effects of use and disuse, the inherit- 

 ance or non-inheritance of acquired characters, protective 

 mimicry and protective coloration, and many others; and 

 not only these will have a value to the specialist, but even 

 those who are dealing with the applied science will have to 

 deal with these problems. 



Of the foreign species of insects, that have from time to 

 time come to the State, and of the otheis that are on the 

 way, it will be necessary to sav comparatively little. We 

 know from where the most of them came, if we are aware 

 of their presence at all, and considerable of their habits in 

 their native land. In the first place, I have come to seriously 

 doubt whether or not we are likely to observe a foreign 

 species on its first appearance, with any remarkable degree 

 of promptness, and in the second place, it seems that, often 

 at least, a species must be introduced more than once before 

 it can succeed in adapting itself to the changed conditions 

 and flourish. Take the Clover Leaf Weevil, Phyiotonms 

 ■pimdatus Fab., which suddenly became destructively abund- 

 ant in Central Western New York, in 1881, before which 

 time it had not been known in America, but as it turned out 

 later, a specimen had been found 25 or 30 years before and 

 had been described as another species i^P. opiums Lee.) in 

 1876, while, singularly enough, a specimen has since been 

 found in the stomach of a crow, shot in Michigan, May 8, 

 1892, the year when it was first reported in Ohio, probably 

 200 miles east of the locality in Michigan, where the crow 

 was killed. The Clover Root Borer, Hylastcs trifoIti\ Riley 

 broke out as seveiely and as suddenly in the same locality 

 in 1878, when, in all probability, it had occurred in the 

 country for years, unknown and unobserved. The Aspara- 

 gus Beetle, Crioceris asfaragi Linn., though establishing 

 itself, permanently, in this country about 1856 or 1857, was^
