WERNER MARCH AND 67 



HcEmatopota decora Walker. — An African species, which prefers 

 low and dry country, therefore not common in the Mlanje district of 

 southern Nyasaland, where Neave made his studies. However, 

 Neave has acquainted us with the larval and pupal stages. 



The larva was of the usual Hcematopota type, but the pigmented 

 areas on the anal segment were an orange color. This might, how- 

 ever, have been due to the mature condition of the larva, which was 

 about to pupate. The pupal aster is regular in shape. A dorso- 

 lateral comb consisting of three spines is present. Pupal aster and 

 dorsolateral comb of a female are figured (Plate 13, Fig. 169, a, b). 



Hcematopota insatiahilis Austen. — An African species, abundant 

 near Mt. Mlanje, southern Nyasaland, about November and early 

 December, according to Neave (1915). 



A few larvae of Hatnatopota insatiahilis were obtained, and from 

 some of these, three females were bred between November 7 and 10, 

 1913. The three posterior segments of "what is believed to be the 

 larva of this species" are figured (Plate 6, Fig. 86). There seems to be 

 no pigmentation except a narrow double ring at the posterior end 

 of the eleventh segment. The circular ridge on the tenth segment 

 shows no pigmentation. The twelfth segment is very short and 

 rounded. 



The pupa is figured (Plate 11, Fig. 131) but not described. The 

 pupal aster of this species (Plate 13, Fig. 172, a, b, c) is very remark- 

 able, the upper hooks being reduced to mere knobs, while the middle 

 pair are enormously enlarged. A well marked dorsolateral comb 

 is present. Pupal aster of the female in side view and from behind is 

 figured, also the dorsolateral comb. 



HcEmatopota pluvialis Linne. — One of the commonest and most 

 widely spread tabanids in Europe, known also to torment the rein- 

 deer in Lapland, where it occurs in incredible numbers. It is the 

 representative of a genus spread all over the world but absent in 

 Australia, while in Africa it is represented by a large number of 

 species. 



In the more recent literature nothing is found concerning the life 

 history of this species, the earlier work having escaped attention of 

 recent investigators.
