13. Keguttomyia MACULiPENNis Lw, (Stratiomyiclie). 2. i.22.. 

 This fly was buzzing up and clown the white ceiling of a lighted 

 room, when it was approached by an exceptionally large gecko 

 \lleviidactylus mahouia), who followed its movements for some 



.time, but hesitated to take it. 



13 a. 6. iv. 22. Another example with closed wings, showing its 

 close resemblance to the model. During tlie five months since 

 2. i.22 five specimens were taken on the gauze, it being about 

 equally common with the model in this situation. There is a bee 

 here very similarly coloured.^ 



14. Apis mellifera adansoni Latr. 22.iii. 22. This bee is 

 a plague , existing in countless thousands in the plantation and 

 often milking its combs in the houses (see p. lOlD). 



15. EniSTALODES quinqukmaculatus F., $ (Kiistaliniu : Syr- 

 phida?). 2. i.22. Common but not exactly plentiful ; buzzes like 

 the bee both in flight and when caught ; it causes quite a pricking 

 of the fingers with its feet when held. On 31. iii. 22 I caught one 



.of these flies and offered it to my monkey (Cercopithecus albigu- 

 laris rujilatus), who would have nothing to do with it though he 

 eyed it closely. I then proffered it to a Fennec Fox ( Octocyon vir- 

 gatus), who was watching me and was within two feet of the 

 monkey at the time. He promptly snapped it out of my fingers 

 and crunched it up. I then released the monkey, who went ofl" 

 hunting grasshoppers, and was still busy feeding when I went to 

 bring him in half-an-hour later, so it v^as not a question of 

 satiety '"''. 



16. Megachile sp., ? UNGULATA Smith, $ (Apidaj : Anthophila). 

 6.vi.21. A common wild bee. Another bee, Nomia vulpina 

 Gerst., would act a as model with (16), as also with (14), and (39) ; 

 and all four species form together a compound colour associatioix 

 into which still other bees probably enter. 



17. SiMoiDES CRASSIPES F., 2 CEristalinse). 21. iii, 22. A mimic 

 of (16). 



18. PsAMMOCHARES sp. B. l.iv. 22. Common. 



19 & 19 a. Plagiostenopterina submetallica Lw. (Steno- 

 pterinae: Ortalidw). 11.&15. v, 22. In houses even commoner 

 than the alleged model ; when walking slowly up the gauze with 

 closed wings they look very waspish. 



20. IcARiA AMBIGUA Gribodo (Yespida3 : Diploptera). l.iv. 22. 

 This wasp builds small nests on the verandah, where the little 

 colonies of from two to five individuals are quite a common 

 spectacle. 



21. Odyn'erus tropicalis Sauss., $ (Vespidte). l.iv. 22. 

 A closely-related species with similar habits.

 (Trans. Ent. Soc. 1921, pp. 25, 31, 33, 72, 100). ...
