always holding their wings lying flatly upon the back when not in usp>, instead of 

 holding them partly expanded, as the Lestophoni do. The latter when disturbed 

 usually fly upward, and are thus easily liberated from the sacks, while the Chalcids 

 when disturbed simply leap a short distance and again alight lower down upon the 

 inside of the sack. I have examined these sacks every few days and carefully de- 

 stroyed the Chalcids and then liberated the Lestophoni. These two muslin sacks I 

 kept inside the tent. The contents of some of the tin boxes which were in worse 

 condition I put in a paper bag, pinned it shut and kept it in my room ; nothing but 

 Chalcids have appeared in this bag, and all of these have been carefully destroyed. 

 Altogether there have issued from this second sending up to date twenty-four Lesto- 

 phoni and one hundred and sixty-one Chalcids. — [D. W. Coquillett, Los Angeles,

GENERAL NOTES. 



BOILING WATER FOR PEACH BORER. 



Mr. John B. Haas, in the Pacific Rural Press for March 22, gives 

 the result of a very conclusive experience in Missouri some years ago. 

 He removed the soil around his infested trees for a depth of 3 or 4 

 inches, making a trench from 3 to 6 inches in width, and poured a buck- 

 etful of water, boiling hot, all around the trunk of the tree, allowing it 

 to remain in the trench. He states that it killed all of the borers pres- 

 ent and that his trees, which had been covered at the base with gummy 

 exudation and had been in very bad condition, rapidly improved and 

 bore fine crops. 



THE FAMILY PHYLLOXERID^. 



Dr. L. Dreyfus, in the 6k Zoologischer Anzieger," No. 316, 1889, has 

 published a little statement to the effect that his new family which he 

 had erected in his work entitled "Uber Phylloxerinen," Wiesbaden, 1889, 

 should be given the "idse" termination instead of the "inse." He 

 therefore gives as the four families of the suborder Phytophthires : (1) 

 Coccidse; (2) Phylloxeridse : (3) Aphidae; (4) Psyllidse. 



THE NEWLY IMPORTED ROSE SAW-FLY. 



Mr. J. G. Jack refers in Garden and Forest of March 26, 1890, to the 

 introduction of the European Emphytus cinctas into this country. He 

 has found it feeding upon the roses in the Arnold arboretum at Cam- 

 bridge in the summer of 1887 and succeeded in rearing the adult in the 

 autumn of 1888. This species is from two to three times as large as a 

 common Rose Saw-fly, has a white band around the body of the female, 

 and is more active. The eggs are deposited singly on the under side 

 of the leaf and there are two or three annual generations.
