IXSECTS AFFECTING PARK AND WOODLAND TREES 513 



Description. This beetle is about 3/i6 inch in length, subtriangular in 

 outline, metallic in color, the head and thorax being golden, the basal por- 

 tion of the wing cov'ers greenish and purple and their tips reddish and 

 yellow. 



The larva has been described by Professor Gillette as "whitish, 9 mm 

 long, ilattencd, segments deeply notchc-tl ; head widest and body gradually 

 tapering to the tail. The mandibles are brown and the prothoracic segment 

 has brown, rectangular plates above and below. The anal extremity is 

 provided with a small spine extending behind, which is used by the larva in 

 progression." 



Life history and habits. The adults, as stated above, feed on elm 

 leaves, and according to Professor Gillette, probably on oak also. He 

 states that in October 1886, while collecting leaf miners, he obtained larvae 

 of two of these beetles from pojilar, from which adults were bred later. 

 Dr Packard states that he has found this small buprestid on the leaves of 

 oak early in summer in Maine, and late in May near Providence, and adds 

 that the larva probably mines the foliage. 



Distribution. This species is probably generally distributed in the 

 northeastern United States at least, since it has been recorded from th(; 

 vicinity of Buffalo N. Y., from southwestern Pennsylvania and the District 

 of Columbia, and is not rare on oak throughout New Jersey. 



Brachys ovata Weber 



A small, triangular, metallic colored beetle about ^i^ inch in length, may be found 

 abundantly on scrub oak foliage in May and June. 



This species was very numerous on scrub oaks at Karner during the 

 latter part of May and June 1901. The beetles rested quietly on the 

 leaves or ate irregular holes through the tissues and when startled, flew 

 readily. 



Description. This small, flattened buprestid is subtriangular in outline, 

 metallic green or olive in color and ornamented with sparse gray and 

 fulvous pubescence. The elytra have a stout, sublateral ridge, and there 

 may be one or two more or less rudimentary ones between it and the suture.
