found ovipositing on 21st August. The larvae from these eggs pupated 

 about 9th October. The larvae of Argyresthia aUernatella occur within 

 the seeds. Moths were observed on 24th May and eggs on 6th June. 

 The mature larva feeds on the fleshy part of mite-infested berries. 

 The majority of larvae became mature on 25th September. The 

 natural enemies include Secodella sp., Prolapanteles sp., and members 

 of the family Encyrtidae. Berries growing near St. Paul contained 

 a Cecidomyid larva, together with a Tetrastichus larva in the same 

 cell. 



Surface (H. A.). For Walnut Caterpillars. — Zool. Press Bull., Penns. 

 Deft. Agric, Harrisburg, no. 321, 21st June 1915. 



For controlling Datana integerrima, S. and R., (walnut red-necked 

 caterpillar), attacking the foliage of black walnut trees, a spray con 

 taining 1 oz. of lead arsenate in a gallon of water is recommended. 

 It is also feasible to burn them, provided that the burning is slight and 

 quickly done, so as not to damage the branches ; injury to the foliage 

 is not serious. These caterpillars have a peculiar habit of coming 

 down the trunks in large bunches and clinging together while they 

 moult ; such bunches should be destroyed. These remedies are 

 also suitable for the very similar species which attacks the apple, the 

 red-necked apple caterpillar {Datana ministra, Dru.). 



Earned (R. W.). Blister Beetles. — Mississippi Agric. Expt Sta., Press 

 circ, 9th June 1915. 



The Meloidae or blister beetles attack tomatoes, potatoes, beans 

 and other garden and field crops in Mississippi. The insects appear 

 in large numbers in the year following an outbreak of grasshoppers, xf 



upon the eggs of which the larvae of the beetles feed. Lead arsenate 

 dusted upon the plants or used as a spray at the rate of 1 lb. of paste 

 to 15 gals, water or Bordeaux mixture has been found satisfactory. 

 Paris green and lime as a dust or spray gives good results. Hand 

 picking or driving into a ditch coated with oil is often practicable. 

 To prevent further outbreaks, it is advisable to take steps to control 

 the grasshoppers [see this Review, Ser. A, iii, p. 263]. 



Harned (R. W.). The Corn Stalk Beetle. — Mississippi A. & M. 

 College Extension Service, Agric. Coll., Press circ, 19tli June 1915, 



The corn stalk beetle [Ligyrus rugiceps] has recently been very 

 abundant in Mississippi. Injury is caused by the beetles eating into 

 the stalks of the maize plants close to the ground. When the plants 

 are young, the stalk is severed, while older plants are injured so that 

 they soon wither. There is one generation a year. The eggs are laid 

 on or near the roots of maize, sugar-cane or other members of the grass 

 family. The larvae feed on the roots until autrmn, when pupation 

 takes place. The f.dult emerges in the following spring. Deep 

 autumn and winter ploughing, crop rotation, hand picking of adults 

 in spring and allowing pigs to feed in badly infested fields, have proved 

 suitable remedies.
