728 THE FOOD PLANTS OF SCALE INSECTS— COCEERELL. 



CARYOPHYLLE^E. 



In Europe Stellaria holostea supports, in common with various otlicr 

 low i)lauts, Orthezid iirticw, Linuivus.' 



TAMARISCINEyE. 



A small order, best known by the Old World genus TamarLv, common 

 in cultivation. T. gallica of Mount Sinai aud other localities produces 

 the (lossj/jxtria vi a unif era, Hurdwick. In cultivation, I have found the 

 tamarisk free from coccids, but Coquillett records Icerya j;»r(7<a*i, 

 jMaskell, exogenetically upon it. 



Fouquicra splcndens, one of the most curious native plants of Kew 

 Mexico and northern Mexico, commonly used for hedges, is rarely found 

 infested by Dactylopius townsendi, Cockerell. 



HYPERICINE.^. 



The unrecognizable Coccu.s hi/periconin^ Gmelin, is recorded from the 

 European Hyperienm 2>er/orati()n. 



GUTTIFERyE. 



A large order of tropical trees and shrnbs, mostly American and 

 Asiatic, Chi.siti <ilh<i, ,Ia('<juin, is attacked by Icerya montserrateii.sis, 

 Itiley and Howard, in Trinidad. j\[ammea americand, Linmeus, is cul- 

 tivated in the Sandwich Islands, and there infested by Pulrinaria 

 mammciv, ^laskcll, which, however, may be exogenctic. At any rate, 

 no such Pulvinarid has been found on the mammee in the West Indies. 



TERNSTRCEMIACEyE. 



Another fairly large order, well known from the camellia and tea plant, 

 both now referred to the genus Camellia, ^chima crenata is cited as a 

 food plant of Tachardia lacca, Kerr. The common camellia, G.japonica^ 

 a native of Jai>an and China, is much attacked by scale insects in cul 

 tivation. The list is Aspi(1iotu.s s2)i)iosiis, Comstock, A. rapax, Comstock, 

 A. (legeneratiis, Leonard!, Fiorinia fiorinUe var. cameUicv, Comstock, 

 r<(rltiioria jKryatidei, Comstock, var. camellia', Comstock, Pulrinaria 

 cavicUicola, Siguoret, Lcca)iium hrsperidum, Linnanis, L. oleic, Bernard, 

 L. hemisplucricum, Targioni Tozzetti. Ghermes camellice of Boisdmal 

 can not now be identified; it can not well be what Siguoret calh'd 

 A,sj>i(li(>tus camellia; which is A. rapax. IJoisduval's insect was also 

 found on the tea plant. AspidiotK.s duplex, Cockerell, was found bj' 

 Mr. Ehrhorn on camellia from Japan, at a Japanese nursery in San 

 Erancisco. Ceropla,stc.s cerifcrns, Anderson, was found by Mr. Craw on 



I Douglas, Traus. Eut. Soc. Loml., 1881, p. 298.
