THE SOUTHERN PINE SAWYEK. 43 



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

 near DeUslow, W. Va. In the same year Chittenden published a 

 a short account of the destructive habits of the species of the genus 

 Monohammus. J. B. Smith, in his Insects of New Jersey, published 

 the same year, mentions this species as occm-ring throughout the 

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

 ing Park and Woodland Trees, under the name 21. titiUator (common 

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

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

 on both white pine and hard pine. 



DISTRIBUTION. 



The records of the Bureau of Entomology indicate that tlais species 

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

 Maine to Texas. As stated iu the historical notes, Doctor Horn 

 gave the distribution as fi-om Canada to TTashington Territory, 

 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 only piue trees, not favoring 

 any one species of pine, but apparently attackiag all species of 

 pine trees withiu its range of distribution. 



CONDITION OF TREES ATTACKED. 



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

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

 from this source. 



INJURY TO PINE FORESTS BY STORMS. 



In September, 1906,- a high wind accompanied by rain, blowing 

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

 ber iu the southern part of Mississippi. 



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

 felled about 800,000 feet of pine timber. 



On AprO 24, 1908, a cyclone of huge proportions passed through 

 Mississippi and Louisiana, 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 timber. It is quite probable that the 

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

 occurred in Arkansas, one in April and one in May, 1908, both of 

 which were verj- destructive to pine timber. During the fall and 

 winter of 1908 two or three more storms occurred in the same State 

 which doubtless contributed to the destruction of the pine forests.
