shallow grooves in the surface of the wood. The irregular, wavy or ser- 

 pentine galleries enlarge with the growth of the larva and differ in general 

 appearance from the borings of other insects inhabiting similar situations. 

 This, the largest of the Bat-headed pine borers, was met with rather com- 

 monly by tlie writer on hard pine at Karner in 1901 from early in June to 

 the latter part of September. The record of captures is as follows : June 

 4, two; June 13, two; June 26, four; July 8, two; 

 August 9, two and September 18, one. The beetle 

 may be> found resting on the sunny side of the trunks 

 and branches and occasionally among the needles of 

 the smaller twigs. It is i)robabIy attracted by light, 

 since one was taken in a trap lantern. The adult is a 

 dark metallic gray colored beetle measuring from i to 

 ly^ inches in length. 



Dr Packard states that the beetles appear in the 

 Northern States toward the end of May and occur 

 through the month of June, according to Harris, while 

 ginieiiMs. en .irsed long.na ) j^^ obscrvecl tlicm In Maine on pinetrees in the mid- 

 dle of July. Dr LeConte records this species as abundant in the Middle, 

 Eastern and Southern States and adds that this form may be readily distin- 

 guished by its dull color, fine punctuation of the depressed spaces of the 

 wing covers, of which the four impressed spaces are better defined than 

 any others, and finally by the sides of the thorax being anteriorly rounded 

 to the middle and not at all angulated. 



Smaller flat-headed pine borer

 This species may be distinguished from C. v i r g i n i e n s i s Drury by its smaller 

 size, it ranging from about 3/( inch in lengtli, and by the brilliant coppery color which is 

 usually much more marked than in C. v i r g i n i e n s i s. 



It was taken by the writer in relatively small numbers on hard pine at 

 Karner in 1901 as follows: June 4, one; June 13, four; September 6, one 

 and October 3, one. Dr Fitch states that this species is much more com-
