Ferris (G. F). A New Species in the Hormaphidinae (Hemiptera, 

 Aphididae). — Ent. News, Philadelphia, xxxii, no. 10, December 

 1921, pp. 289-291, 1 plate. 



A description is given of Hamamelistes (?) agrifoliae, sp. n., from 

 small twigs and the lower surface of leaves of Quercus agrifolia in 

 California. The author considers this species to be representative of 

 a new genus, but alate specimens will be necessary to determine 

 this definitely. Only three species of the subfamily Hormaphidinae 

 appear to have been recorded from the United States, and of these 

 one is introduced. 



SwEZEY (O. H.). Wireworm Damage in Hamakua. — Hawaiian 

 Planters' Record, Honoluhi, xxvi, no. 1, January 1922, pp. 6-10, 

 4 figs. 



Wireworms have caused damage to sugar-cane planted in February 

 1921 at Hamakua. They have been collected in fields on the other 

 Islands, but have usually been predacious on other insects and have 

 not damaged the sugar-cane. Investigations indicate that Monocre- 

 pidius exul does not occur in distinct broods at definite times of the 

 year, larvae of various ages being found all the year round. Simodac- 

 tylus cinnamomeus occurs less frequently, but injured some cane in 

 August. This wireworm eats the eyes, burrowing inside and eating 

 round the joint so that the stem is easily broken apart at that point. 

 It also burrows lengthwise. 



Search in the Philippines and in Queensland for parasites of these 

 wireworms that might be successfully introduced into Hawaii, has 

 hitherto been unsuccessful. No results have been obtained with 

 insecticides and repellents. Sodium cyanide, 300 lb. per acre, is said 

 to kill all wireworms, but even 150 lb. per acre is fatal to maize plants. 

 It may be possible to use this fumigant in sugar-cane fields at the 

 time of planting, though it may prove too expensive for practical 

 purposes. 



Delassus ( — ). Le Chloropicrine et son Emploi pour la Destruction 

 des Parasites animaux. — Rev. Agric. Afr. Nord, Algiers, xx, 

 no. 131, 3rd February 1922. pp. 78-81. 



The methods by which chloropicrin can advantageously be used 

 for the destruction of insect pests are briefly reviewed, and a more 

 extended employment of this insecticide in xA.lgeria is advocated. Its use 

 in connection with horse mange and against certain pests of grain and of 

 fruit-trees has been particularly successful, and although the technique 

 to be employed is not yet fully understood, it is thought that it 

 will prove of considerable help to agriculturists against insects injurious 

 to animals and cultivated plants.

 of July and August 1921.— Mthly. Bull. Cal. Dept. Agric., 

 Sacramento, x, no. 9, September 1921, pp. 381-385. 



The pests intercepted during July and August were : — From New 

 York, Lepidosaphes heckii on grapefruit. From Michigan, Aphis 

 sp. on Chrysanthemum. From Ohio, Saissetia hemisphaerica on 

 ferns ; and Tetranychus sp. and Myzus rosarum on roses. From New 

 Jersey, Diaspis boisduvali and Eucalymnatus tessellatus on orchids.
