INSECT ENEMIES OF THE REDWOOi).

The Monterey Cypress Bark-Beetle. 



{PMcm.nnuf: cristaius Lec.) 



This is another Cedai- barli-beetle which is closely allied to the pre- 

 ceding, and is the true crista tus, with which several other species have 

 heretofore been confused. 



In February, 1893, specimens of this insect and its work were sent 

 to the Division of Entomology by Mr. J. Dickee, Riverside, Cal., with 

 a statement that it was doing great 

 damage to Cypress hedges in Contra 

 Costa County, Cal. Nothing fur- 

 ther is known of its habits, but it is 

 possible that it may also attack the 

 Redwood. (Fig. 4.) 



The other species of insects found 

 by the writer in Guerneville, Cal., 

 in Redwood, may be briefly men- 

 tioned as follows: 

 ■■ Phymatodes decussatiis Ijqc. This 

 long-horn beetle (Cerambycid) was 



reared from a section of a small dead tree, and the larva of probably 

 the same insect was found in the bark of a dying tree. 



Callidiimi janthiniivi Lec. A dead adult of this well-known enemy 

 of Cedai- was found en the bark of a log, where it had evidentlv lired.

IMMUNITY OF REDWOOD FROM ATTACK BY TERMITES OR WHITE 



ANTS. 



Probably the first officially published record of the relation of Red- 

 wood to the wood-destroying' termites of tropical regions was that 

 which appeared in Bulletin No. 30, new series, Division of Entomol- 

 ogy, [J. S. Department of Agriculture (1901), p. 95. This reference 

 is quoted as follows: 



December 13, 1900, we received a communication through a lirm of lumber mer- 

 chants of San Francisco, Cal., which appears to indicate that the California Red- 

 wood lumber is immune to the attack of white ants or termites. Through the firm 

 in question we received a letter from Mr. J. E. Norton, dated December 4, relating 

 to the resistance of this wood to the so-called Manila white ant of Annia. His letter 

 is in substance as follows: 



"In the latter part of 1898 I secured from a transiDort a piece of Redwood lumber 

 in a yard at AlanUa. The spot was damp, and various pieces of timber all around 

 showed evidence of the existence of the ant in abundance. This piece lay undis- 

 turbed for a period of five or six months, and when examined was found as sound as 

 when put there, not having been attacked by any insects. The Chinaman, owner 

 of the lumber yard, was still doubtful and undertook to get it eaten by putting it in 

 different places under different conditions, such as on top of pieces already inhabited, 

 between boards, and underneath piles, and finally, after three months, jDut the sam- 

 ple on exhibition in his office with the following placard: 'Madera Colorado de 

 California, no se comen Annai.'
