The Curculio on the Apple. (Country Gentleman, for July 21, 1887, 

 Hi, p. 565, c. 3—4 - — 23 cm.) 



Apples from Moosehead City, N. C, submitted for examination, are 

 gnarled and distorted from the numerous blackened pits that they 

 bear, which are particularly described No insects are found in the 

 fruit. The punctures were probably made by the plum curculio, Cono- 

 trachelus nenn.phnr, for feeding purposes. The apple curculio, Anthono- 

 mus quadrigibbus, is described. Curculio attack is to be met by jarring 

 the insects from the trees on sheets spread underneath. 



An Ichneumonized Caterpillar. (Country Gentleman, for September 

 1, 1887, lii, p. 673, c. 3-4 — 13 cm.) 



Darapsa Mijron larva, from a grapevine at Nassau, N. Y., has its 

 body covered with the cocoons of a small ichneumon fly, which is 

 Apanteles congregatus. The history of this common parasite of D. 

 Myron is given, with reference to an error that is often made of mistak- 

 ing its cocoons for insect eggs and destroying them. 



Milkweed Beetle with Bad Habits. (Country Gentleman, for Septem- 

 ber 1, 1887, lii, p. 673, c. 4 — 27 cm.) 



Larvae sent from Chenango Co., N. Y., as feeding commonly on the 

 morning-glory, but also on barley, corn, cabbage, and some weeds are 

 identifled as those of Chehjmorjiha Argus Licht. The beetle is described. 

 The literature of its food-habits is given, showing that it had not 

 hitherto been observed as a corn depredator. It does not promise to be 

 destructive to valuable ci'ops. When numerous it may be controlled by 

 hand-picking or shaking from the plants. 



Blister Beetle Attack. (Country Gentleman, for September 1, 1887, 

 lii, p. 674, c. 2— 6 cm.) 



A beetle from Morton, Pa., charged with having devoured in one 

 night the leaves of a Clematis flammula, is identifled as Epicauta c'merea 

 (Forst.), the marginata of Fabricius. Remedy, spraying with Paris 

 green in water. 



Mites on Arbor Vitse. (Country Gentleman, for September 1, 1887, 

 lii, p. 674, c. 3 — 9 cm.) 



The blackened appearance of a twig of Siberian arbor vitte, sent 

 with inquiry from Pittsburgh, Pa., is due to an attack of a minute mite, 

 the egg-shells and exuviae of which are discernable under a magnifier. 

 The attack can be arrested by spraying with pyrethrum water, or if on 

 small trees by sulphur burned underneath with sheets spread over 

 them to confine the fumes.
