90 REPORT OF THE STATE ENTOMOLOGIST 1,921 



nearly black beetle about one-fourth of an inch long, remarkable 

 because of the very large terminal antennal segment which equals 

 in the female and greatly exceeds in length in the male the 

 remainder of that organ. The larvae of this little beetle prey upon 

 a number of wood borers and in our experience it was reared from 

 late March until July from a hickory log cut the preceding Feb- 

 ruary. This log and accompanying branches were badly infested 

 with a number of insects, Sinoxylon basilare Lee. being 

 the most abundant in the branches. 



Agrilus otiosus Say, one of the small Buprestids, has 

 been taken on ash, oak, butternut and locust foliage and has been 

 recorded as boring in maple, dogwood, red bud, hickory, black 

 walnut and as probably infesting butternut, box elder, and perhaps 

 locust. It was reared in March from a hickory log cut in February 

 191 5, and did not issue after July 20th. 



Hickory snout beetle (Magdalis olyra Herbst.). This 

 black, long snouted beetle about three-sixteenths of an inch in length 

 breeds commonly in dying or dead hickory limbs. It appears to 

 confine its attacks very largely to sickly trees or parts of trees and 

 sometimes occurs in enormous numbers, in which event the inner 

 bark and sap wood may be almost riddled by the many irregular 

 branching galleries. This species was reared in small numbers the 

 latter part of March 191 5, from branches collected the preceding 

 February. 



Hickory twig borer (Chramesus hicoriae Lee.) This 

 is a minute, short, stout, black beetle about one-sixteenth of an inch 

 in length occurring quite commonly in hickory twigs ranging from 

 three-fifths of an inch to an inch in diameter. The burrows are 

 mostly in the wood and lightly score the bark. There is a single 

 main gallery about an inch long, the eggs being deposited at nearly 

 regular intervals on each side and the larvae working for a short 

 distance at approximately right angles and then turning and boring 

 nearly parallel with the wood fibers. A few specimens of this 

 insect were reared the last of March 11915, from twigs collected 

 the preceding February. 



Red-shouldered twig borer (Sinoxylon basilare Say) . 

 This small, cylindrical, stout, black, red-shouldered beetle about 

 one-fifth of an inch long has been recorded as occurring in the 

 twigs and branches of a considerable variety of trees, such as hick- 

 ory, persimmon, mulberry, apple, peach and grape vine and Doctor 

 Hopkins states that it breeds in most other deciduous trees.
