The Coccidae and their hosts which have been collected in Peru 

 are enumerated, viz. : — Aspidiotus rapax, Sign, {camelliae), is seldom 

 a serious pest and is evidently kept in check by hymenopterous 

 parasites ; A. cyanophylli, Sign., A. cydoniae, Comst., A.hederae, Vail. ; 

 A. juglans-regiae, Comst., probably an introduction of the last few 

 years, recorded once on Juglans sp. ; Aidacaspis rosae, Bouche, 

 especially damaging roses which it often kills, it has several broods 

 per year, and has not been noted on any other host ; Ceroplastes sp. 

 (near ceriferus) on (?) Mimosa ; Chrysomphalus sp. n. ? (near rossi), on 

 Araucaria excelsa and A. bidivilli ; Coccus hesperidmn, Linn., attacks 

 a large variety of hosts, but is checked by hymenopterous parasites ; 

 Diaspis boisduvallii, Sign., is widely distributed and has a preference 

 for monocotyledonous plants, especially palms ; D. echinocacti, 

 Bouche, found occasionally on Opuntia only ; Fiorinia fioriniae, 

 Targ., only collected on ornamental, cultivated plants, including 

 Cocos sp., Phormium tenax, and Asclepias sp. ; Hemichionaspis minor. 

 Mask., is especially a cotton pest in the cotton regions, but also occurs on 

 other plants. Lepidosaphes beckii, Newm., was formerly very des- 

 tructive to orange trees of which there are now few left in the area ; 

 Orthezia insignis, Dougl. ; Selinaspidus (Pseudaonidia) articulatus, 

 Morg., is the commonest and most widely distributed Coccid in 

 Peru, attacking a wide range of food-plants, including, Ficiis, Citrus 

 and Rosa, it does more damage to Citrus than does Chrysomphalus 

 aurantii in CaUfornia ; fumigation, however, is never practised in 

 Peru and parasites do not seem to check it ; Pseudococcus citri, Risso, 

 is widely distributed, but in limited numbers, and is subject to 

 parasitic and predaceous enemies ; it has been collected on Coffea 

 arahica amongst other plants ; Saissetia hemisphaerica, Targ. ; 

 Saissetia oleae, Bern. ; collected from cotton.

An account is given of the difficulties attending the artificial intro- 

 duction of fungi for the purpose of controlUng noxious insects. Many 

 parasitic fungi, have been cultivated on artificial media or on hving 

 insects kept in confinement and have also been introduced among 

 healthy insects, but the cases in which they have become established, 

 distributed and effective are not so numerous. Spore emulsions of 

 Botrytis bassiana successfully infected nun moth caterpillars [Lyman- 

 tria monacha, L.] in the laboratory, but failed to do so in nature ; 

 similarly Cordyceps mililaris only gave negative results in the field.
