fusco-ferrugineis; palpis, antennis, tegulis pedibusque ferru- 
gineis ; fronte clypeoque pallidissime aureo-pubescentibus; seg- 
mentis dorsalibus secundo, tertio quartoque angulis apicalibus 
late argenteo-pubescentibus ; pygidio fusco-ferrugineo setoso; 
alis flavo-hyalinis, venis ferrugineis. 
6. Femine similis ; fronte clypeoque lete aureo-pubescentibus. 
Long., 2 23, ¢ 22 mm. 
2. Clypeus broadly subtruncate. at the apex; galea 
distinctly longer than broad, rounded at the apex; palpi not 
elongate. Second and third joints of the flagellum subequal ; 
eyes separated on the vertex by a distance about equal to the 
length of the second joint of the flagellum. Vertex very 
minutely and closely punctured, with a low longitudinal 
carina from the occiput not reaching to the ocellar space. 
Posterior slope of the median segment irregularly trans- 
versely striated ; a small smooth triangular depression at the 
apex of the dorsal surface of the segment, which is finely 
rugulose and about half as long again as the scutellum. 
Dorsal surface of the abdomen shining, closely and minutely 
punctured; pygidial area broadly rounded at the apex. 
Sternites 2-4 shining, with large scattered punctures. Basal 
joint of the fore tarsus with six rather short and stout spines ; 
spur of the hind tibia Jonger than the basal joint of the hind 
tarsus. Second and third abscisse of the radius subequal ; 
the space between the recurrent nervures on the cubitus equal 
to the second abscissa of the radius. 
3. Clypeus very broadly rounded at the apex ; eyes very 
close together on the vertex, separated by a distance scarcely 
equal to the length of the first joint of the flagellum. Seventh 
dorsal segment broadly rounded at the apex; eighth ventral 
segment subtruncate, very feebly emarginate in the middle, 
the angles not produced. Sternites shining, sparsely punc- 
tured, but more closely and finely than in the female. 
Hab. Yapi, Gold Coast (J. J. Simpson), November 1916. 
This is near 7. testaceinerva, Cam., differing in the much 
sparser pubescence of the thorax and median segment, in the 
distinctly longer galea, in the presence of a carina on the 
vertex of the female, in the broader pygidial area, and in the 
distinctly sparser punctures of the sternites; the seventh 
tergite of the male is also much broader. 
Tachytes obliqua, Sm. 
Larrada obliqua, Sva, Cat. Hym. B.M. iy. p. 281 (1856), ¢ (as 2). 
This is a Zachytes somewhat allied to silverlock?, Turn.,
