 CalilOTma.— Stanford Univ. Pubns., California, Biol. Sci., i, 

 no. 2, 1921, pp. 61-132, 53 figs. 



Of the 85 species of Coccids dealt with the following are described 



as new -.—Steatococcus tabernicolus, gen. et sp. n., on Prosopis sp. ; 



Orthezia caudata on a Composite, probably Encelia palmer i ; Aster o- 



lecanium cristatum on Heteromeles arbutifolia, Jatropha canescens, and 



other plants ; Eriococcus paucispinus on Celosia florihunda ; E. 



tillandsiae on Tillandsia recitrvata ; Fonscolohibia peninsularis on 



Asdepias subulata ; Xerococcus fouqiiieriae, gen. et sp. n., on Fou- 



quieria peninsularis ; Phenacoccus franseriae on Franseria sp. and 



other plants ; Aclerda attenuata on Distichlis spicata and Arundo ; 



Pulvinaria peninsularis on Philibertia tomentella and other plants ; 



Tourney ella cerifera on Albizzia occidentalis ; Protodiaspis lagunae on 



Quercus brandegeei ; Ancepaspis novemdentata on Lysiloma sp. ; 



Diaspis simmondsiae on Simmondsia californica ; Pseudodiaspis 



elaphrii on Elaphrium microphyllum ; P. ruelliae on Ruellia sp.; 



P. magna on an undetermined shrub; P. prosopidis on Prosopis sp.; 



Chionaspis distichlii on Distichlis spicata ; Lepidosaphes acuta on an 



undetermined shrub ; L. calcarata on Haematoxylon boreale, Acacia 



flexicaulis and other plants ; L. obtecta on Atriplex and Acacia ; 



L. peninsularis on Porophyllum gracilis and Asdepias subulata ; 



Odonaspis litorosa on Rachidospermimi mexicanum ; (9. fistulata on 



Distichlis spicata ; Aspidiotiis chortinus on Chaetochloa caudata ; -4. 



pedilanthi on Pedilanthus macrocarpa, Popuhis and other plants ; 



Chrysomphalus enceliae on Encelia palmeri ; and C. induratus on 



Pinus cembroides, Quercus brandegeei, and other plants. 



Possibly some of these may eventually prove to be identical with 

 species described from Mexico.

Owing to the activities of the parasites Scutellista cyanea and 

 Aphycus lounsburyi, the black scale Saissetia oleae is seldom found 

 in orchards in South Africa. A. lounsburyi has now also become 

 established in California. Consignments of Coccinellids [Novius 

 cardinalis] were sent to Brazil and Ceylon for the control of the 

 Australian bug [Icerya purchasi]. The menace of the pink boll- 

 worm [Platyedra gossypiella] is emphasised by the finding of the pest 

 in a consignment of cotton in Portuguese East Africa [R.A.E., A, 

 ix, 98]. The cotton originated in Angola, where the occurrence of 

 P. gossypiella has apparently not been recognised. 



There is every reason to think that the parasite [Aphelinus mali] 

 of the woolly Aphis [Eriosoma lanigermn], introduced from America, 

 will become established in Africa. 



The San Jose scale [Aspidiotus perniciosus] has been recorded 

 from four centres in the Orange Free State. Winter spraying and 

 general care of the trees is advocated against this pest. 



Lema bilineata (tobacco slug) is causing uneasiness amongst growers 

 of Cape gooseberries in the Bathurst district. Cape Province [cf. R.A.E., 

 A, ix, 186].
