surrounded by three very narrow yellow lines, one at each end and one in 

 the middle ; scutel yellow ; wing cases crossed by three yellow bands ; first, 

 a semicircular band from the scutel running backwards and round up to 

 each shoulder ; then another of similar shape about the middle, with the 

 circle reversed ; then a straight band, and a strong spine at the tip of each ; 

 length, Yz inch ; width, '/y inch. 



It is separated, according to Professor Wickham, from allied forms, by 

 the femora not being spinose, its falciform antennae and the many strongly 

 elevated, though more or less confused transverse ridges on the thorax, in 

 connection with its apically rounded elytra and the yellowish, transverse 

 bands forming an oval figure at the base of each, behind which are two 

 slightly oblique fasciae. This species is reported as rare in New Jersey. 

 It has been listed from the District of Columbia, where the adults were 

 found on flowers and trees, and Dr Hopkins has taken it in West Virginia. 

 The latter reports it as very injurious to dying trees and sawlogs of black 

 ash, the larvae making numerous holes in the wood. Mr Beutenmuller, in 

 addition to the food plants given above, records it also from the limbs and 

 trunk of elm and hickory. 



Two-lined chestnut borer 



Agrihis btlnica/iis W^eber 



This white, fiat headed pruh maizes very tortuous interlacing burrows under chestnut 

 and oak bark. 



This species was brought to the writer's attention in November 1901 

 because of severe injury to oaks at Geneseo. Several large trees had been 

 killed by the work of this borer and examination of the infested bark 

 showed that the inner layers were very badly riddled by the interlacing 

 galleries of this insect. 



Early history. This species is comparatively unknown to economic 

 entomologists. It was recorded by Dr Packard as occurring under the 

 bark of an oaktree at Providence R. 1. He found pupae May 30, and 

 beetles were common on the leaves. Mr Adams Tollman of Concord 

 Mass., reports taking over 100 specimens of this beetle on white oak June 

 15, 1885, and Dr A. D. Hopkins, writing of this insect in 1894, states that
