fatigans, Wied. Others were C. thalassius, Theo., Anopheles costalis, Lw., 

 A. funestus, Giles, A. mauritianus, Grp., Lutzia (Culex) tigripes var. 

 fuscus, Theo., Culex decens, Theo., C. tritaeniorhynchus , Giles, Culicio- 

 myia nehulosa, Theo., Cyathomyia fusca, Theo., Mimomyia hispida, 

 Theo., M. mimomyiaformis, Newst., Aedes {OclilerotaUis) apico annul atus, 

 Edw., A. {0.) irritans, Theo., A. {Stegomyia) luteocephalus, Newst., 

 A. (S.) nietallictis, Edw., and A. (S.) simpsoni, Theo. Of the adult 

 mosquitos taken in houses 80 per cent, were collected in August, and 

 84-5 per cent, of the total number were C. fatigans, which proves that 

 very few individuals of A . argenteus appear indoors during the bright 

 hours of the day. When the rainfall is low the number of A . argenteus 

 increases in the samples of larvae, while C. fatigans decreases. Other 

 species collected in houses were A. (0.) irritans, C. thalassius, Anopheles 

 costalis, A .funestus, Banksinella lineatopennis, Ludl., and C. qiiasigelidiis, 

 Theo. 



The pouched rat, Cricetomys gambianus, almost equals Mus rattus 

 in numbers and is heavily parasitised by Xenopsylla aequisetosus , 

 End. It is possible that like A', astia in India [R.A.E., B, ix, 125], 

 this flea may be a less efficient carrier of plague than X. cheopis, which 

 might account for the localisation of the disease so far noticed at 

 Accra. 



Cimex {Clinocoris) hemiptera, F., was also found on C. gambianus, 

 and the Gamasid mite, Laelaps echidnimis, Berl., was taken on Mus 

 decumanus. 



An Anthomyiid fly, Lispa armipes, Beck., was taken in two collec- 

 tions of insects. It is an abundant fly in West Africa where its habits 

 of preying on mosquitos are similar to those of the Chinese species, 

 Lispa sinensis, Schiner [cf. also R.A.E., B, ix, 42.]

Hippoboscid flies recorded from Cuba are Ornithoctona ha'itiensis, 

 Bigot, and Ornithoctona albiventris, sp. n., and Ornithoica melaleuca, 

 sp. n., from owls. Keys to the genera Ornithoctona and Ornithoica 

 are given.

These keys to the subfamilies and genera of Tabanidae according 

 to the author's classification are reproduced without notes as an 

 excerpt from a more extensive work on the subject. Many new genera 

 are proposed.

The Hymenopterous parasite of Musca domestica (house-fly) found 

 in stable manure in Fiji [R.A.E., B, x, 169] has now been identified 

 as a species of Spalangia. Two or three species of this genus are known 

 as parasites of Diptera in Queensland and Hawaii, and the one in 

 question has probably been introduced from one of these sources.
