276 Mr. E. E. Austen on new 



judging from a comparison of the type of H. puniens with a 

 co-type of H. abyssinica kindly presented by M. Surcouf, 

 H. puniens is distinguished by coarser and more closely knit 

 wing-markings, a distinctly shorter stigma, at the proximal 

 extremity of which there is a more conspicuous pale mark, 

 and by the greater distinctness of the lower band on the 

 front tibiae. From other species with similar abdominal 

 markings, such as H. mactans, Austen, H. stimulans, Austen, 

 and H. furtiva, Austen, and allied species, H. puniens may be 

 distinguished at once, inter alia, by there being no trace of a 

 bifurcation in the apical sinuous mark in the wing and by 

 the presence of two pale bands on the front tibiae ; the elon- 

 gate shape of the large admedian abdominal spots and the 

 narrowness of the median stripe on the abdominal segments 

 (even the stripe on the second segment is in no way expanded 

 towards the hind margin) afford further characters for the 

 recognition of this species. Among the specimens of 

 Hamatopota from N. Nigeria, presented by Mr. Brand, is a 

 female from Garran Gabbus, July 1907, which is evidently 

 closely allied to H. puniens but apparently belongs to a 

 distinct species. The individual in question agrees with the 

 type of H. puniens in the markings on the tibiae, but differs 

 in having the first joint of the antennae much more swollen, 

 as well as paler at the base and darker at the tip, in the 

 stigma being less complete, and in the presence of a light 

 streak beyond it along the costa ; the sjDecimen is in very 

 bad condition, and the abdomen (evidently owing to the 

 presence and decomposition of contained blood) is so distorted 

 that little can be seen of its markings, but there are traces 

 of elongate grey spots on the dorsum. 



Hcematopota sanguinaria, Austen. 



(Ann. & Mag. Nat. Hist. ser. 8, vol. i. May 1908, p. 417.) 



Since this species was described, from a specimen from 

 Kasempa District, N.W. Rhodesia, three additional examples 

 have been received from N.E. Rhodesia, including 2 ? ? 

 from Luena District, 9. ix. 1904 (R. L. Harger), — one caught 

 at noon and the other taken by the donor on his own thumb 

 about 7.30 p.m., — and 1 ? from the Kafulafuka River, 

 Kapopo District, Sept. 1904 (J. F. F. Johnson). This fresh 

 material agrees with the type and paratopes in all respects 

 except size, the new specimens measuring 9"5 mm. instead of 

 8 to 86 mm. in length.
