292 Mr. R. E. Turner on Fossorial Hymenoptera, 
and nigroannulatus, Bisch. The posterior ocelli are not as 
long as in most species of the genus. Eighth sternite 
rounded at the apex. I overlooked this species in my recent 
revision of the Ethiopian Tachytes. 
Tachytes braunsi, sp. n. 
36. Niger, albo-pilosus; palpis brunneis; tarsis ferrugineis, basi 
infumatis; segmentis dorsalibus 1-4 fascia apicali argenteo- 
pubescente ; segmento dorsali septimo argenteo-pubescente ; 
segmento ventrali octavo apice truncato ; alis flavo-hyalinis, yenis 
ferrugineis, tegulis pallide luteis. 
@. Mari simillima; segmento dorsali sexto pallide aureo-pubes- 
cente. 
Long., g 14, 2 15 mm. 
3. Clypeus very broadly rounded at the apex, clothed 
with dull silver pubescence which extends on to the front. 
Eyes separated on the vertex by a distance slightly exceeding 
the length of the second joint of the flagellum ; the vertex 
closely and finely punctured. Thorax and median segment 
rather sparsely clothed with erect whitish hairs ; median 
segment nearly twice as long as the scutellum, with a shallow 
longitudinal sulcus. Second sternite very closely and rather 
finely punctured ; eighth sternite truncate at the apex, the 
angles not produced; seventh tergite broadly rounded at the 
apex. Basal joint of fore tarsus with four spines. Second 
and third abscissee of the radius subequal, shorter than the 
first ; the third cubital cell on the cubitus extending a little 
beyond the apex of the radial cell. Galea broader than long. 
9. Eyes separated on the vertex by a distance equal to 
the combined length of the two basal joints of the flagellum ; 
basal joint of the tore tarsus with four spines ; second sternite 
more finely punctured than in the male; third sternite 
shining, with large scattered punctures ; sixth tergite elongate- 
triangular, pointed at the apex. 
Hab. Willowmore, Cape Province (Dr. Brauns), No- 
vember and December. 
This somewhat resembles 7. erynnis, Turn., but differs in 
the number of spines on the fore metatarsus, in the colour of 
the pubescence on the thorax, in the deeper colour of the 
wings, and in the shape of the apical segments in both sexes.
