Neoclytus erythrocephalus Pabr. The small, reddish beetles with 

 their three yellow, nearly transverse Lines on each wing-cover, were 

 reared in some numbers from a large hickory log collected in mid- 

 winter. The insects continued to emerge during the summer and 

 one living specimen was found the following midwinter. The data 

 indicate one generation annually for this species though there may 

 be occasional specimens which would carry over to the second season. 

 This borer has been reared from the dead wood of a considerable 

 variety of trees. 



GARDEN INSECTS 



Box leaf midge (Monarthropalpus buxi Lab.) . The 

 receipt, through Thomas J. Wade, city forester, New Rochelle, N. Y., 

 in early May, of a twig of box showing a serious infestation by this 

 insect, indicates a gradual spread of the midge and accompanying 

 injury. This is especially likely to occur in places where box is 

 extensively used as an ornamental or hedge plant. The affected 

 leaves contained numerous full-grown, yellowish maggots, a few 

 transforming maggots and some recently transformed pupae, indi- 

 cating that emergence would not be long delayed. The reception 

 May 27th of infested box leaves containing pupae from Philadelphia, 

 indicates that the flies are not likely to emerge along the Atlantic 

 coast prior to the last of May or early in June. This matter is of 

 some importance in connection with remedial measures. 



The presence of this recently introduced enemy of box is indicated 

 by more or less irregular, oval swellings on the leaves, each marking 

 an eccentric, oval, clear space mined beneath by one or more pale, 

 yellowish, white maggots about one-sixteenth of an inch long. There 

 may be a very slight elevation of the leaf with an irregular, yellowish 

 or brownish discoloration, the margin of the enlargement being 

 indicated by darker green. This condition is most easily observed 

 in September and later after the maggots are more than half grown. 

 An infested leaf may contain only one or two of the miners and be 

 injured to only a comparatively slight extent or there may be six 

 or more of the maggots and a nearly total destruction of the leaf. 

 Attack by this midge weakens the plants and results in the badly 

 infested leaves dropping in the spring, leaving unsightly, bare stems 

 with new leaves developing at the tip. 



The known occurrence of this species at Newport, R. I., New 

 Rochelle, Westchester county, Roslyn and probably other Long Island 

 localities and Philadelphia, Pa., suggests that it is likely to appear in 

 numbers in almost any place along the northern Atlantic coast, and
