178 ENTOMOLOGY FOR MEDICAL OFFICERS 



(" infuscated ") as to look like two spots. It is distinguished 

 from G. fusca, inter alia, by having (i) the proboscis and 

 palpi much shorter ; (2) the characteristic thoracic markings 

 washed out in appearance; and (3) the wings paler. It is 

 distinguished from G. longipennis by the points emphasised 

 in Austen's table. 



Glossina medicorum, Austen. 



According to Austen, this species is known, at present, 

 only from West Africa. It is the smallest of the G. fusca and 

 G. brevipalpis groups, Austen's measurements being for the 

 male 9 to 10 mm., and for the female 10 to io-6 mm. It 

 is said to present a superficial resemblance to G. brevipalpis, 

 but to be distinguishable from that species by the uniformly 

 pale wings. 



Glossina longipennis, Corti. 



An East African species, which, according to Austen, has 

 up to the present time been recorded only from Somaliland 

 and the East Africa Protectorate. It is said to be one of the 

 most easily recognised of all the large tsetse-flies, by the 

 four small dark brown spots on the dorsum of the thorax, 

 and by the sharply defined dark-brown tip of the bulb of the 

 proboscis. 



Postscript. — Dr A. G. Bagshawe has just published the 

 information (Sleeping Sickness Bureau, Bulletin No. 29, 

 p. 291) that he has just learned through Dr Kleine that Dr 

 Taute, on L. Tanganyika, "has successfully transmitted a 

 human trypanosome to monkeys by means of Glossina 

 morsitans."
