MAPLE BOKERS. ^ 387 



OQ the metathoracic segmeut is of a double lunoid shape. The first 

 abdomiual segment has a short, narrow dorsal area, shorter than the 

 one on the preceding segment. The lateral linear crescent- shaped im- 

 pressed lines are well marked. 



This larva differs from that of Chrysohothris femorata in being con- 

 siderably larger, the abdominal segments being thicker in proportion 

 to the prothorax, and also in the style of sculpturing on the prothorax. 

 The apex of the V i^ surrounded by a square, deeper-colored area ; the 

 disk on the under side is divided by a double line, which widens sud- 

 denly in front into halves. 



9. The quercitron bark-borer. 



Graphisurus fasciatua (De Geer). 



Order Coleoptera ; family CERAMBYCiDiE. 



This beetle, more commonly found on the oak, has been found in the 

 pupa as well as adult stage under the bark of the sugar maple in North- 

 ern New York by Mr. George Hunt ; and we have reared the beetle 

 from a pupa found under the bark of the red or swamp maple, at 

 Providence, June 1. The cell made by the larva for the repose of the 

 pupa is about an inch long, one-third of an inch wide, and one-tenth 

 deep. (See also p. 71.) 



10. Xyloterus politus 8a,y. 

 Order Coleoptera ; family Scolytid^. 



In this species, according to Leconte, the elytra have ill-defined dis- 

 tant rows of punctures, with interspaces equally strongly punctured, 

 pubescence erect and abundant. He has received specimens from Dr. 

 J. A. Lintner, said by him to depredate on maple trees. " It is easily 

 known," adds Leconte, " by being more hairy than the other species, 

 with the interspaces of the elytra sparsely punctured, so that the rows 

 of punctures appear confused." 



11. Bellamira scalaris Say. 



This longicorn has been taken by Mr. Harrington in the act of ovi- 

 positing in a maple stump in July. It also attacks the birch. 



The beetle. — Head contracted behind the eyes to form a neck ; thorax narrow ; 

 wing-covers pubescent, glistening, rather wide at the base, but tapering rapidly 

 behind, and shorter than the abdomen. Reddish, with yellowish antenniB and feet. 

 Length, 25™™ to 30™™. 



12. The white ant. 



Termes flavipes Kollar. 



The following copy of an article by Dr. H. A. Hagen (Can. Ent, xvii, 

 p. 134) shows that this insect, usually only destructive to rotten wood, 

 may rarely attack living trees.
