 t. p. line is geminate, making it appear twice as hroad as the t. a. line, the interven-

 along its inner bend: a line extends from the elbow to the s. t. line, which runs veiy 

 close to the outer margin, starting from the costa a little before the apex and gradu- 

 ally nearing the margin until upon the submedianvein it sometimes becomes coinci- 

 dent with it: there is also a narrow terminal line, and the space between it and the 

 subterminal is also yellowish : fringes at the apex, with an ocherous interline : reni-

On April IT of tlie present year tlie Secretary of Agriculture referred 

 to the Division the following letter: 



Coleman's Falls, Va., April. 9, 1S93, 

 Sir: I hare had over 1.000 peach, pear, and plum trees entirely denuded of all 

 blossoms and buds, both active and dormant, in less than forty-eight hours by a flea- 

 beetle whose attack I have not been able to arrest up to the present writing. If 

 you can send an agent to study habits and remedies in the interest of horticulture 

 I will extend hospitality, force-pumps, labor, etc., necessary to his purpose. 

 Respectfully, 



Geo. E. Muerell. 



Xo Specimens accompanied this communication, but the insect attack 

 therein described appeared to be of sutlicient importance to call for 

 fiu-ther investigation. We therefore insti^ucted Mr. E. A. Schwarz to 

 proceed as soon as practicable to Mr. Murrell's place to learn all he 

 could about the injury. This he has done and we append his report. 



REPORT OF E. A. SCHWARZ. 



Mr. MurrelTs farm at Coleman's Falls is situated at the base of a high spur of the 

 Blue Eidge Mountains. The numerous narrow valleys in this section of the country 

 are separated from each other by rather flat-topped ridges, which are usually covered 

 with a magnificent gTowth of chestnut trees. Black locusttrees {EoVinia pseudacacia) 

 are very rarely met with in the chestnut forest on these ridges, though they are 

 common to the valleys along the roads and fields as well as on the edge^of the forest. 

 If, however, the chestnut trees on the ridge be cut down, they are speedily succeeded 

 by a dense growth of shrubbery mostly composed of Eobinias. 



The insect invasion presently to be described took place on the top of one of these 

 ridges which years ago had been cleared, and where for a number of years oats 

 and other field crops had been cultivated. Six years ago this cultivation had been 

 abandoned, and the clearing was overrun with locust bushes. In the month of 

 March, of the present year. Mr. Murrell had this shrubbery grubbed up. plowed the
