314 Fiftieth REroRT ox the State Museum 



The species not being recognized in its larval stage, no examples were 

 retained for the State Collection, nor description made of it, but several 

 of the pupae were preserved in alcohol. I have not found any description 

 of tlie early stages of this insect, nor of its larval habits. Of the latter 

 Dr. Thomas has written : " the larvae, probably, like those of other known 

 species (of Cetonians), live in rotten wood, as the perfect insects are 

 often seen flying over chip yards, probably in search of a convenient 

 nidus for their eggs " (4th Illinois Report, page 91). From the above, 

 taken in consideration with the occurrence of the larva at Menands, it 

 may be inferred that chip manure is its favorite habitat. 



Do the larvre feed also on growing vegetation ? State Botanist Peck 

 from whom the larvae were obtained, had applied some of the manure to 

 a few hills of corn in his garden. The following day one of the hills was 

 noticed to have been cut down, as if by cut-worms. Upon digging 

 around the stalks, two larvte of the Euphoria were discovered, but no 

 cut-worms, from which it would seem probable that the grubs had com- 

 mitted the injury. 



The Elaphidion Oak Pruner. 



The oak pruner, Elaphidiflti villosum (Fabr.) is not, I believe, of fre- 

 quent occurrence on apple trees, but during the first week of June, its 

 operations were very noticeable in an orchard in Voorheesville, Albany 

 county, where a large number of twigs and branches had been thrown to 

 the ground by it. Some of the branches brought to me were from three- 

 tenths to seven-tenths of an inch in diameter. Each contained the 

 mature and active larva, within a closed cell in its burrow, prepared for 

 pupation. 



The maple-tree pruner, E.parallehun Newm. (regarded by many as 

 identical with the preceding species) was very abundant in early June in 

 the maples bordering the avenues in the grounds of Governor Morton, 

 at EUerslie, in Dutchess county. Not a maple was seen which had not a 

 score or two of the recently fallen pruned branches lying beneath it, 

 although previous gatherings had been made and destroyed. 



The Asparagus Beetle. 



The asparagus beetle, Crioceris asparagi (Linn.), is continuing its 

 spread in the central and western counties of the State. In my Ninth 

 Report, reference is made of its appearance at Geneva, Ontario county in
