Only adults have been observed. Eggs are said to be laid on the 

 trunk of the tree ; the larvae tunnel in the trunk and branches longi- 

 tudinally until the tree dies. Unhealthy trees are preferred for attack, 

 though vigorous ones are sometimes infested. The beetle evidently 

 has considerable powers of flight, as no timber occurred in the immediate 

 vicinity of the orchard tree attacked.

 British Guiana. — Psvche, Boston, Mass., xxix, no. 4, August 1922, 

 pp. 132-152, 2 plate's. 



All the Coccids dealt with in this paper are related to ants, these 

 relations having a common peculiarity ; in all the cases the ants are 

 supplied with food in the form of a secretion or excretion elaborated 

 from the juices of the plants. Wasmann has designated these relations 

 trophobiosis to distinguish them from myrmecophily proper. 



The species dealt with are Stigmacoccus asper, Hempel, foimd in a 

 large colony of Cremastogaster sp. (near acuta, F.) under the bark of a 

 large tree ; Pseudococcus bromeliae, Bch. (this species is subject to 

 a certain degree of variation in respect of the structural characters 

 that are at present regarded as of taxonomic value, but in spite of 

 recent suggestions 'R.A.E., A, x, 604] the author prefers to retain 

 this name until further evidence as to its correct systematic position 

 has been obtained) ; P. rotundatiis, sp. n., from cavities of stems of 

 Cecropia angidata ; Farinococcus imdtispinosus, gen. et sp. n. , from cavities 

 of stems of Triplaris siirinamensis with a new species of Psetidomyrma ; 

 Riper sia petiolicola, sp. n., from hollow bases of leaf petioles of Tachi- 

 galia paniculata ; R. subcorticus, sp. n., under the bark of a living 

 tree ; Akermes qidnquepori, Newst., for which additional descriptive 

 notes are given, taken beneath the bark of Ficus [ulmifolia ?), inside 

 hollowed-out twigs of Pithecolohimn sanian, and also from an unknown 

 tree in Trinidad; and ^. secretus, sp. n., in cavities of stems of Triplaris 

 siirinamensis, and also in branches of Inga laurina (guama) from 

 Porto Rico, under the bark of Hematoxylon campechianinn (logwood) 

 from Grenada, and in Tobago and Trinidad. 



Akermes {Pseudophilippia) inquilina, Newst. [R.A.E., A, viii, 119] 

 is considered to have little or no relationship to the genotype of 

 Pseudophilippia and is obviously related to the two preceding species. 

 According to the figures and somewhat incorhplete description it 

 stands in an intermediate position between qiiinqtiepori and secretus.

 Family Eurytomidae, with a Description of its Larva and Pupa. — 



Psyche, Boston, Mass., xxix, no. 4, August 1922, pp. 153-158. 



This new genus includes two new species, Conoaxima aztecicida 

 parasitising queens of Azteca constructor, Emery, and A. alfaroi, 

 Emery, in British Guiana, and C. affinis attacking Azteca in Guatemala.

Aphis hiltoni, sp. n., is described from the Laguna Canyon, Cali- 

 fornia, where it was formd in dense colonies on the apical twigs of 

 California sage {Artemisia calif ornica).
