116 THE CANADIAN ENTOMOLOGIST. 



Now, when the moth borer and the weevil work together and pretty 

 much in the same way, i. e., by cutting the inner bark and the cambium 

 layer, thus scoring and girdling the stem, to which culprit belongs the 

 greatest amount of credit for mischief ? Both are guilty of enough to 

 justify everlasting execration. 



It remains to add a word about its insect enemies. The hymenop- 

 terous parasite which Mr. Grote found to fill certain of the chrysalids, I 

 have found in every location where the moth is at all abundant ; there is 

 another which I have found quite as abundant. Early in April I obtained 

 from the galleries of last year a number of brown cocoons, about .4 of an 

 inch long, nearly cylindrical, ends rounded, texture thin papery, pupa 

 visible through the cocoon. The skin and head of the victim was found 

 at one end of this cocoon, showing that the caterpillar was the host. 



In a few days there appeared from each cocoon a lively fly. Expanse 

 of male .6 in., of female .7 in. Color above black, legs yellow, underside 

 of abdomen white with a row of black dashes on side, front of male 

 white, of female black. A white line on shoulder of each extends on to 

 the costa. Ovipositor as long as the abdomen. 



I shall presently refer the species for identification. 



ENTOMOLOGICAL CLUB OF THE AMERICAN ASSOCIATION 

 FOR THE ADVANCEMENT OF SCIENCE. 



The Annual Meeting of this Club will be held at Saratoga, N. Y., on 

 Tuesday, August 26th, at 2 p. m. All Entomologists are invited to meet 

 with the Club. A series of interesting meetings is expected to be held 

 during the week. B. Pickman Mann, Secretary. 



[The place of meeting this year being so central and easy of access, it 

 is expected that an unusually large number of Entomologists will be 

 present. It is hoped that all will come with copious notes and with 

 memories well stored with personal recollections of insects and their 

 habits, so that a large mass of useful information may be submitted. The 

 discussions at these yearly meetings are always of very great interest, while 

 the social charms attending such a reunion of kindred spirits add greatly 

 to the pleasures of the occasion. — Ed. Can. Ent.]
