rum) have occurred on the same, recorded by Signoret as T. platypkylla. 

 Signoret also gives M. UneaHs as from T. sylrestris and L. Hike from 

 T. communis, wliicli is, I suppose, T. vuh/aris, Ilayue. 



Apeiha tibourhon, Aublct, a native of Guiana and Venezuela, exhibits 

 a few Aspuliotns personatus, Comstock, and A. articulatuf^, Morgan, 

 when cultivated in Jamaica. 



The New Zealand Ehvocarpus dentafus supports, according to Mas- 

 keW, CtenochitoH eUvocarpL Maskell, a.//(rrw.s^ Maskell, InfiUsia ornata, 

 Maskell, and Erloeoccus palUdus, Maskell. The Australian E. etjaneus, 

 Sims, in cultivation in this country, has yielded Chionaspis hiclaris, 

 Comstock, as reported by Comstock. 



ZYGOPHYLLE.^. 



A small and diverse order of herbs, shrubs, and trees. In Jamaica 

 Bmtylopim rirgatus, Cockerell, is found upon Trihuhis eisloides. The 

 Larrea divaricata or mexloana of the arid region of North America 

 exhibits in Arizona Tachardia 1arre(v, Comstock, and in the Mesilla 

 Valley of New Mexico Iccri/a rileyi, Cockerell, and JDactylopius toim- 

 sendi var. steelii, Cockerell. It is curious that I have never been able 

 to find T. larrecc in New IMexico, though the Larrea is so abundant. 



In Jamaica the beautiful lignum- vita? tree {Guaiacum officinale) is a 

 food plant of CeroplaHtes cirripediformis, Comstock, C. ^fIoriden.sis, Com- 

 stock, C. depressus, Cockerell, Iccryarosa\ Riley and Howard (under tlie 

 hark), Leca7iium olecv, Bernard (rarely), ^.spwZtotws rnnYn*//;, Maskell, 

 and a Lccanium heretofore presumed to be tessellatun) but probably 

 distinct. 



GERANIACE.^. 



Cultivated Pelargoniums are especially liable to the attacks of 7>w.s- 

 pis amyddaU, Tryon, but may also be infested by Fseudoparlatoria 

 ostreata. Lounsl)ury reports Orfhezia imiguis, Douglas, on Pelarfio. 

 nium, as also on OxalLs. Comstock records Orfhezia amerieana, Walker, 

 from Impatiens. 



RUTACE^^. 



A large order of shrubs and trees, most numerous in South Africa 

 and Australia, best known by the orange. 



The African genus Diosma has been found attacked by the exoge- 

 netic Aspidioius rapax, Comstock, or cameUhv, Signoret.^ Diosma crenata 

 is reported as supporting the problematical Cocciis diosmatis, Modeer; 

 this plant, however, is not a Diosma, but a Barosma, B. crenulata, Lin- 

 naeus. The New Zealand 2Ielicope teniata, Forster, furnishes Erioch Hon 

 spi7iosus, Maskell. The hop tree, Ptelea trifoUata, Linnanis, is cited by 

 Comstock as one of the various food plants of Uytilaspis pomornm, 

 Bouche. Murraya exotica, when cultivated in Jamaica, is infested by
