Insecta. 21 



Both sexes fed with equal avidity. The males died much sooner than the females. 

 Some of the flies were kept alive for over 2 months. Many of the females when 

 first caught contained larvae in various stages of development, and gave birth 

 to these in captivity: it thus appears that production of larvae proceeds during 

 the dry season. Copulation, which was frequently observed, lasts for several 

 hours, and may take place more than once between the same pair of flies. Fe- 

 males often produced larvae at intervals of 14 — 15 days, biit sometimes the in- 

 terval was longer. The extrusion of the larva is very rapidly accomplished, the 

 newly-born maggot commencing to crawl about immediately. Intra-uterine pu- 

 pation was never observed. When placed on earth the larva at once commences 

 to burrow, and after reaching a depth of 1 or 2 cm becomes quiet and proceeds 

 to pupate: the head is retracted, the oval puparial form is assumed, and the 

 skin gradually hardens and darkens, these changes occupying 4 — 5 hours. The 

 pupae were placed in glass tubes exposed to the laboratory air, and the imagines 

 emerged from 47 to 53 days after the birth of the larva. 



The larva is described and figured: it closely resembles the known larvae 

 of other species of the genus, having conspicuous black tumid lips on the last 

 Segment. The puparium is also figured. H. Scott (Cambridge).

The author remarks that although Roubaud has recorded (Sleeping Sick- 

 ness Bull. III, S. 419) that in West Africa G. morsitans dies if exposed for an 

 hour to a temperature of 40" C, yet in the Luangwa Valley ( Rhodesia) the same 

 species frequently endures in a wild state a still higher temperature. The period 

 of pupation of this species has been found at a mean temperature of 85^ F., to 

 Vary from 21 to 25 days, averaging 23 days. Ä method of extracting the sali- 

 vary glands of Glossina is described. H. Scott (Cambridge).

 and habits of Glossina fuscipes in Uganda. In: Bull. Ent. Research, 

 Bd. III, Heft 1, S. 55—59, 1912. 



In the Nile Province of the Uganda Protectorate G. fuscipes is chiefly found 

 in places where rivers have clean rocky banks and where there is a certain amount 

 of shade from trees and scrub. The flies are found in the fringes of small forest 

 along the streams, but not usually at any distance from water, unless the forest 

 stretiches continuously from the water and affords shade. Along the large rivers 

 cTc? appear to be much more numerous than ?$, while 5$ seem more numerous 

 than d^c? along the smaller streams. The author considers that all the Glossina 

 found East of the watershed (i. e., between the Great Lakes and the Nile System 

 on the one hand, and the Congo system on the other) and referred to G. palpaUs, 

 are really G. fuscipes: and that consequently G. fuscipes is an intermediate host 

 of Trypanosoma gamhiense and a carrier of sleeping-sickness , in addition to G. 

 palpalis. H. Scott (Cambridge).

In Northern Nigeria G. palpalis is fairly widely-distributed over the country 

 during the wet season, but as the dry season advances it retreats towards the
