THE tfOUTITEKN PINE SAWYER. 43 



of this species resting upon pitch and scrub pine trees at Tibbs Run, 

 near Dellslow, W. Va. In tlie same year Chittenden jiubHshed a 

 a short account of the destructive lial)its of the species of the genus 

 Monohammus. ,L B. Sniitli, in his Insects of New Jersey, pubHshed 

 the same year, mentions this species as occurring throughout the 

 State on pine in June and July. In 1906 Felt, in his Insects Affect- 

 ing Park and Woodland Trees, under the name M. titillator (common 

 name, tickler), published a very short description, saying further 

 that it was met witii in very small numbers [in New York] in 1901 

 on both white pine and h;u-<l |)ine. 



DISTRIBUTION. 



The records of the Bureau of P^ntomology indicate that this species 

 is to be found over the whole eastern half of the United States, from 

 Maine to Texas. As stated in the historical notes. Doctor Horn 

 gave the distribution as from Canada to Washington Territoiy, 

 and south to Florida, but I have not been able to verify his state- 

 ment as to the northern and western limits of distribution. 



HOST PLANTS. 



So far as known, this species attacks onl}^ pine trees, not favoring 

 any one species of pine, but aj)parently attacking all species of 

 pine trees within its range of distribution. 



CONDITION OF TREES ATTACKED. 



Only felled or injured trees are attacked by this species. So far 

 as known, healthy standing trees are never in any danger whatever 

 from this source. 



INJURY TO PINE FORESTS BY STORMS. 



In September, 19()(), a high wind accomi)anied l)y rain, blowing 

 steadily for two or three days, uprooted a vast amount of pine tim- 

 ber in the southern part of Mississippi. 



In May, 1907, near Tuscaloosa, Ala., a storm occurred which 

 felled about 800,000 feet of pine timber. 



On April 24, 1908, a cyclone of huge proporti(ms j)assed through 

 Mississipj)i and I^ouisiana, tearing down a swath of timber from 1 

 to 2 miles wide (fig. 13). The cyclone passed through some of the 

 finest pine forests in these States, thus bringing down or breaking 

 off many millions of feet of tiin])er. It is (piite probable that the 

 same storm did damage in Arkansas. At any rate, two storms 

 occurred in Arkansas, one in April an<l one in May, 190S, both of 

 which were very destructive to pine tind)er. During the fall and 

 winter of 1908 two or three more storms occurred in the s:nn(> Sfat<> 

 whicli doubtless contributed to the destruction of the |)in(' forests.
