severely injured by Brassolis sophorae, L. [see this Review, Ser. A, iv., 

 p. 66]. Castnia daedalus, Cram., was present on coconut, but the 

 rate of spread appeared to be slow. A. cephalotes proved injurious 

 to young trees in some districts. Attempts to destroy the nests of 

 this ant by the use of carbon bisulphide, calcium carbide and burning 

 sulphur met with only partial success, as the large colonies were almost 

 unafFected. Insect pes^"s of rice included Diatraea saccharalis, F., 

 and Laphygma frvgiperda, S. & A. Cacao and coffee were attacked 

 by scale-insects in several cases. The larvae of the butterfly, Gynaecia 

 dirce, were recorded as feeding on the foliage of coffee. 



A collection of Thrips made in the Colony comprised the following 

 species : — Frankliniella insularis, Frank., from flowers of Couroupita 

 guyanensis (cannon-ball tree) ; Heliothrips haemorrhoidalis, Bch., 

 from the underside of the leaves of orange, avocado pear, and other 

 trees ; Diceratothrips armatus, Bagn. ; Dichactothrips brevicollis, 

 Hood ; Eupathithrips silvestrii, Buff a ; Anactinothrips meinerti, Bagn., 

 from palm ; Hoplandrothrips affinis, Hood, from beneath leaf-sheaths 

 of sugar-cane ; Heliothrips rubrocinctus, ¥., on cacao. 



The following list of the Aleurodidae occurring in British Guiana 

 is given : — Dialeurodicu^ pulcherrimus, Q. & B. ; Leonardius sp. ; 

 Aleurodicus cocois, Curt., on coconut and guava ; A. giganteus, Q. & B., 

 on Anona muricata and Cananga odorata ; A. pulvinatus, Mask., on 

 Montrichardia acvleata ; A. neglectus, Q. & B. ; A. sp. on Solanum 

 7nelongena ; Paraleurodes sp. on coconut and ornamental plants ; 

 Eudialeurodiais bodkini, Q. & B., on Erythrina glauca ; and Dialeurodis 

 kirkaldyi, Kotinsky, on leaves of jessamine. 



The following Hymenopterous parasites were reared from hosts of 

 economic importance :■ — Chalcididae : Arrhenophagns chionaspidis 

 Auriv., from Chionaspis minor ; Leptomastix dactylopii, How., from 

 Pseudococcus citri, Risso ; Trichogrmnma minutum, Riley, from eggs of 

 Diatraea saccharalis, F., Laphygma frugiperda, S. & A., etc. ; Holcen- 

 cyrtiis calypso, Cwfd., and Elachertus ineridionalis, Cwfd., from larvae 

 of Calpodes ethlius. Cram. ; Chalcis pandora, Cwfd., from the pupa of a 

 Hesperid butterfly ; Heptasmicra curvilineata. Cam., from the pupa 

 of D. saccharalis, F. ; Aplastomorpha pratti, Cwfd., from Lasioderma 

 serricorne, F. ; Lecaniobius cockerelli, Ashm., from Saissetia nigra, 

 Nietn. ; Tetrastichus hagenowii, Boly. ; Entedononecremnus nnica, 

 Gir., and Coccophagus magniclavus, Gir., from pupa- cases of Eudialeuro- 

 dicus bodkini, Q. & B. ; Eupelmus koebelei, Ashm., from Dipterous 

 larvae. Proctotruptdae : Prophanurus thais, Cwfd., from the eggs 

 of a Pentatomid bug ; P. alecto, Cwfd., from eggs of Diatraea sac- 

 charalis, F. ; P. minutissimus, Ashm., from eggs of a Noctuid moth ; 

 Aphanurus bodkini, Cwfd., from eggs of a Pentatomid, Empicoris
