500 Mr. aw. Edwards on 
Described from two males in good condition in the 
British Museum collection from Mpumu Forest, Uganda, 
July 1910 (Capt. A. D. Fraser, R.A.M.C.). The specimens 
had previously been identified as H. taeniarostris Theobald, 
but are obviously distinct. 
4. H. trichorostris Theobald. See Plate XVI, fig. 7 x 50. 
Differs from H. fraseri as follows :— 
Eyes distinctly separated by a scaled area on the upper part of 
the front, touching below. A large patch of metallic silvery scales 
on head in front. Mesonotum with double median row of metallic 
scales. Male hypopygium large, prominent, yellowish. Side pieces 
three times as long as broad, basal lobes with a tuft of about 10 
spines. Lobes of ninth tergite elongate, with two strong spines 
at the tip and one shorter bristle internal to these. Mesosome 
undivided, strongly chitinised. 
Known only from Theobald’s type male and female 
from Obuasi, Ashanti (Dr. W. M. Graham). 
5. H. farquharsoni, sp. n. See Plate XVI, figs. 9-11 x 50 
and fig. 12 x 200, 
Differs from H. fraseri as follows :— 
Eyes distinctly separated by a scaled area on the upper part of 
the front, touching below. A large patch of metallic silvery scales 
on head in front. Male genitalia small, resembling those of H. 
genurostris except in the structure of the mesosome. Lateral 
silvery spots on segments 5 and 6 of female abdomen very small. 
Six males and five females from Ibadan, 8. Nigeria 
(C. O. Farquharson). None are in perfect condition, but 
none show the metallic thoracic line: two or three metallic 
scales are present on the front of the mesonotum in one 
specimen, but these may have been displaced from the 
prothoracic lobes. 
|The material here described was sent by Mr. Farqu- 
harson in two consignments, of which the first—l J, 
5 O—was intended to illustrate the observations recorded 
~ in Proc. Ent. Soc., Lond., 1918, pp. xxix—xxxix, and was 
exhibited to the Society at the next meeting (pp. xXxxix, 
xl). It was erroneously identified by Mr. “Farquharson 
(p. xxxii) and Dr. Guy Marshall (p. xl) as H. trichorostris 
Theo., and also wrongly sexed (p. xl). The examples were
