 de I'Afrique Occidentale. [New observations on the Choeromyia

When the authors visited Upper Gambia in 1912, they only met 

 with Choerowyia praegrandis, Aiist., and that in very small numbers. 

 Early in 1915 on the same ground, they found all three species which 

 they discovered in the same burrows of Orycteropus. In the red i-and 

 at the back of a burrow nearly 250 feet long numbers of young larvae 

 were found ; pupae, probably of C. boued and C. praegrayidis occurred 

 at the entrance. Adults of both these species and also of C. choerophaga 

 were found.

Auchmeromyia luteola, F. is found all over the Belgian Congo 

 as far above sea-level as human habitations go. The author has taken 

 it at 7,500 feet on the slopes of Ruwenzori. The life-history of 

 CJioeromyia bequaerti, Roub., is still unknown ; it lives under the 

 same conditions as those described by Rouband for C. choerophaga, 

 Roub., in the burrows of Pharochoerus aethiojncus. Pall. The flies 

 were easily caught on the shores of Lake Albert Edward by thrusting 

 a stick into these burrows. Neither living larvae nor pupae have been 

 found ; males predominate largely among the adults. The larger 

 numbers caught enable the author to amplify Roubaud's original 

 description. A specimen of C. choerophaga, Roub., caught in the 

 N.E. corner of the Congo region extends the Eastern range of this 

 species considerably. 



M. Roubaud adds a note to this paper in which he says that the 

 proportion of males to females in C. bequaerti, Roub., varies somewhat 

 with the condition of the burrows ; males are more common in 

 abandoned or rarely used burrows, the females in those which 

 are constantly inhabited and especially where there are young ; 

 defective nutrition of the larvae in his experience leads to a pre- 

 dominance of males.

Glossina palpalis abounds in the mangrove swamps at the mouth 

 of the Congo ; it also occurs at the foot of the rocky cliffs of Landana, 

 even on the sea-shore, and between Liiali and Lukula near all the streams 

 across the south-west limit of the forest of Mayumbe. On the Congo 

 itself, a small jumping spider, Dolomedes sp., and a Libellula were 

 observed to capture and kill G. palpalis. The fly is to be found all 

 along the Aruwimi-Ituri river from its mouth at Asoko. Between 

 Penghe and Irumu, following the forest caravan route from west to 

 east, G. palpalis was only found at one of all the numerous river
