TIIK SOUTHERN PINE SAWYER. 43 



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

 near Dellslow, W. Va. In the same year Chittenden pubhshed a 

 a sliort account of the destructive habits of the species of the ^jjcnus 

 Monohamnius. J. B. Smith, in his Insects of New Jersey, }niblished 

 the same year, mentions this species as occurring; throughout the 

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

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

 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 j)in(' and hard pine. 



DISTRIBUTION. 



The records of the Bureau of Entomology 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 Ilom 

 gave the distribution as from Canada to Washington 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 pine trees, not favoring 

 any one species of phie, but apparcnth' attacking nil sjiecies of 

 pine trees within its range of distribution. 



CONDITION OF TREES ATTACKED. 



Oidy fellcil or injured trees are attacked by this species. So far 

 as known, healthy standing trees are never in anj'' danger whatever 

 from this source. 



INJURY TO PINE FORESTS BY STORMS. 



In Septend)er, 1900, a liigii wind accompanied by rain, blowing 

 steadily for two or three ilays, uprooted a vast amount of i)in(^ tim- 

 ber in the southern part of Mississippi. 



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

 felled about 800,000 feet of pine timber. 



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

 Mis.sissippi and Louisiana, tearing dowM a swath of tind)er from 1 

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

 finest i)ine forests in these States, thus bringing down or breaking 

 off many millions of feet of tiud)er. It is (piite i)robabIe 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 very destructive to })inc tind)er. During the fall and 

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

 which doubtless contributed to the destruction <>f tlu> pine forests.
