of insects which occur on the oUve {Olea cliryso'p'hylla) in that region ; 

 it also inchides a few species talven from Olea verrucosa in South Africa 

 in March 1913, all the others being from Eritrea. Thysanoptera : 

 PMoeothn'ps oleae, Costa. Hemiptera. Tingitidae : Cysteochila 

 jKilIens, Horvath ; C. sordida, Stal, in Cape Colony ; Eu-phylhira 

 aethiofica, sp. n. ; E. longiciliata, sp. n., in Cape Colony. Aleu- 

 EODiDAE : Siphonimisfiyiitinms, gen. et sp. n. Coccidae : Phenacoccus 

 eleabi'us, sp. n., Philippia chrysojihyllae, sp. n., Saissetia oleae, Bern., 

 Asjndiotus opptignatus, sp. n., Chrysomplialus opifmis, sp. n., 

 Selenaspidtis articidatvs, Morg., Ckionasjns olivina, Leonardi. Neur- 

 optera. Chrysopidae : Chrysopa sp., Sympherobius amicus, Navas. 

 Lepidoptera. Besides the species recorded below, larvae of 

 Saturniidae, Sphingidae and Psychidae were collected on Olea 

 chrysophylla, but there was no time to breed them and the species 

 were therefore not determined. Tortricidae : Caryosina chersodes, 

 Mey. Hyponomeutidae : Prays chrysophyllae, sp. n. Lyonetiidae : 

 Oecophyllemhius inferior, sp. n. Coleoptera. Coccinellidae : 

 Chiloconis distigma, Klug, which preys on Chionaspis olivina, Leon ; 

 Nep)}ms veh(stiis, Weise. Chrysomelidae : Argojnstes silvestrii, Weise. 

 CuRCULiONiDAE : Anchonocrami s oleae, Marshall, in Cape Colony and 

 Transvaal ; A. oleae, Marshall, var. pallida, nov. in Eritrea. Hymen- 

 optera. Proctotrupidae : Alloxista peraperta, sp. n., a parasite of 

 Euphyllnra aethiopica, Silv. Chalcididae : Eurytoma oleae, sp. n. ; 

 E. varicolor, sp. n. ; Decatoma aethiopica, sp. n. ; Ormyrvs striatus, Cam., 

 Avhich was found both in Cape Colony and Eritrea ; Eupelmus spermo- 

 jjhihts, sp.n.: E. saissetiae, sp.n., a parasite of Saissetia o/me, whether 

 primary or secondary is unknown ; E. afer, Silv., a parasite of Dacus 

 oleae. (A key is given, by which these three species of EupehuKS may be 

 distinguished between themselves and from E. iirozonus, Dalm., which, 

 in Europe, parasitises various insects, including Dacus oleae.) 

 Eurytoma oleae, E. varicolor, D. aethiopica, 0. striatus, Eupelmus 

 spermophilus and Habrocytus indagans, sp. n., all develop within the 

 stone of Olea chrysophylla, whence they emerge as adults, the first being 

 probably parasitised by the other five. Bothriothorax oleae, sp. n., and 

 B. minor, sp. n., both parasites of Saissetia oleae. Homalotylus vicinus, 

 sp. n., a parasite of the larvae of Nejjhus vetustus, Weise. Aphycus 

 j)raevidens, sp. n., parasitic on Philippia chrysophyllae. Chiloneurus 

 obscurus, sp. n., parasitic on Saissetia oleae. Habrolepis oppugnati, 

 sp. n., a parasite of As])idiotus oppugnatus. Diversinervus elegans, 

 gen. et sp. n., a parasite of Saissetia oleae, though whether primary or 

 secondary is unknown. Allocerellus inquirendus, gen. et sp. n. 

 Halticoptera daci, Silv., a parasite of Dacus oleae. Scutellista cyanea, 

 Motsch., var. obscurata nov., a parasite of Saissetia oleae. Eutelus 

 7nodestus, Silv., from galleries of Dacus oleae larvae. Pachyneuron 

 longiradius, sp. n., and Euryischia leucopidis, sp. n., parasites of 

 Leucopis sp., the larvae of which feed on the eggs of Philippia chryso- 

 ])hyllae. Atoposoma variegatum, Masi, var. afra, Silv., from galleries 

 of Dacus oleae and Oecophyllembius inferior, Silv. Allomphale cavasolae, 

 Silv., an ectophagous parasite of Dacus oleae larvae. Achrysocharis 

 formosa, Westw., var. meridionalis, Silv. (in Cape Colony), parasite 

 of small larvae of Dacus oleae. Teleopterus notandus, Silv., a parasite 

 of the eggs and young larvae of Dacus oleae. Metriocharis viridis, Silv., 

 and M. atrocyanea, Silv., are perhaps parasites of Dacus oleae.
