areas on the upper part of the trunk and branches. The moths appear 

 in May and early June and there is a small second brood during the 

 summer. As in the case of Aegeria (Sanninoidea) exitiosa (peach-tree 

 borer), the most effective means of control is " worming," or digging 

 out the larvae from their burrows. This should be done thoroughly 

 at least twice a year, during October and November, and again in the 

 latter part of May or early in June. All loose parts of dead bark 

 should be removed and the surrounding bark cut with a clean edge, 

 always with the grain of the wood. The wood so exposed should be 

 treated with a strong lime-sulphur solution or thick Bordeaux mixture. 

 A. pictipes has several natural parasites, including a new species of 

 Elachertus that kills the host after the formation of the cocoon, Bracon 

 mellitor, Say, and Microbracon dorsator, Say, which destroys the 

 host in the cocoon before the pupa is formed. From the pupae, Conura 

 sp. n., Pimpla annulipes, Brulle, two species of Campoplex and 

 Mesostermes, have been reared. Ants are known to prey upon the 

 larvae, the hairy wood-pecker on the pupae, and the wood pee- wee on 

 the female moths. Descriptions of the various stages of the insect, 

 its geographical distribution, life-history and habits are also given.

 [Eeceived 19th June 1917.] 



Insect pests of lucerne in Wyoming are not numerous ; grasshoppers 

 occasionally do some harm, but may be controlled by early cultivation. 

 So far, the alfalfa weevil [Hypera variabilis] has been practically 

 absent, reported damage by it having turned out on investigation to 

 be due to the alfalfa looper [Phytometra calif or nica,]. As a control, 

 a strip round the edge of the field and a patch in the middle should be 

 left as bait, heavily sprayed wnth Paris green or lead arsenate, this 

 part of the crop being later cut, dried, and carefully burned. Paris 

 green may be used at the rate of 3 to 4 lb. to 100 U.S. gals, of water, 

 soap, at the rate of 4 lb. to 100 U.S. gals, of water, being added to 

 make the poison spread and stick. When practicable, a ditch of water 

 should surround a badly infested field to prevent the spread of this pest.

The insects that cause most damage to the wood of fruit-trees are 

 Lepidoptera and Coleoptera, the Buprestidae and Scolytidae, 

 being particularly destructive. The Buprestid, Capnodis tenebrionis, 

 L., lays its eggs near the base of the trunk of peach, almond and cherry 

 trees, and the larva eats into the sap-wood of the trunk and roots. 

 The adults may be destroyed by shaking them from the trees, and 

 the larvae by raising the bark over an infested spot and killing them, 

 tar being afterwards applied to the wound. Another Buprestid, 

 Agrilus sinnatus, 01., may be controlled by laying bare the zig-zag 

 borings of the larvae and destroying them, tar being applied as before. 

 Scolytus pruni, Ratz., and^. rugulosus, Ratz., are two very destructive 

 Scolytids that attack plum, pear and apricot trees, while a third,
