All my otber bred Tryphons have been from saw-flies, except Tiypbon signator 

 from Crabro leucostoma, Spleophaga vesparum from Vespa vulgaris, and one Bassus 

 from fly cocoon. It seems strange that he should have bred so many Tryphonids 

 from so unusual a host. I must confess I do not believe it. — [John B. Bridgman, 40

Unslaked Lime against the Rose Chafer. 



Myself and son had last year some 22 acres of grapes to tight the rose chafer on 

 and had nothing ready to fight them with. I went 5 miles and hired a spraying ma- 

 chine and purchased a quantity of lime and carbolic acid, used the dry lime some, 

 but used the lime water mosr, found dry lime would soon blow off; used the liquid 

 very strong. I used 1 bushel of unslaked lime (on some 1^ bushels) to 1 quart of acid 

 (crude) and 50 gallons of water; dissolved the lime and strained. We gave the dose 

 freely and our vines looked white when we got over them. It took us 4 days to cover 

 20 acres. We lost no grapes by bugs after they got the dose. Don't be afraid of lime ; 

 it never killed a vine, but it is a good fertilizer. Some of my vines had the lime stick- 

 ing to the leaves at the close of the season, and grew black and rank from its effects. 



I had the fairest test that could have been given ; had three vineyards and only a 

 driveway between them. The middle place of 1 acre of mixed kinds lay in the center — 

 it had pear trees and currants set among the vines so I could not get through with 

 the machine and as I did not lime them lost the entire crop. These were set as full as 

 any, and across the driveway where I limed them they were full of grapes, so I know 

 the lime killed them. We treated my son's 10 acres first, and he had a heavy crop. 

 On some of my own the bugs worked on the last we sprayed, but the Inez and a new 

 variety which I originated, called the Garfield, neither bug nor rot affected as they 

 had shed their blossoms mostly before they came ; they take the Concords and Bright- 

 ens every time. Neither Paris green nor London purple will affect the bug. The 

 lime shuts off their breathing. The trouble with the dry lime is that it blows off. 

 We only went once over our vines. Shall begin sooner this coming season and go 

 twice over and also use sulphate of copper in connection with the lime for brown 

 rot which we were troubled with this year. The bug does most of his work inside of 

 one week and at time of blossoming. I used about 6 bushels of lime on 20 acres of 

 7-foot high trellis. The spray should be thrown up on under side where bugs and 

 fruit are. We used a low sled to carry tank on. For that purpose a wagon is too 

 high ; liquid runs off. — [S. Justus, Mentor, Ohio, November 27, 1890. 



Abundance of Bombardier Beetles. 



Herewith I transmit to you some insects collected in Minnesota by me while en- 

 gaged as teacher of the Natural Sciences at the State Normal School, Winona, Minn. 

 There is one lot of beetles to which I wish to direct attention especially; it consists 

 largely of species of Brachinus. These I picked up all under one large flat stone near 

 Trempealeau Mountain, Wis., on May 17th of the present year, while oa a collecting 

 trip after botanical and zoological material. For several years past I had taken
