broadly at the apex; eighth sternite broad, shallowly bi- 
sinuate at the apex, the apical angles not produced. Third 
abscissa of the radius nearly twice as long as the second, the 
latter nearly as long as the space between the recurrent 
nervures on the cubitus. Third cubital cell extending on 
the cubitus a little beyond the apex of the radial cell. 
Hab. Portuguese E. Africa, Beira (P. A. Sheppard). 
The broad, bisinuate, eighth sternite distinguishes this 
species from all others of similar colouring. 
34, Tuchytes kristenseni, sp. n. 
Q. Nigra; capite subargenteo-pubescente; thorace segmentoque 
mediano sparse griseo-aureo-pubescentibus, abdomine griseo- 
aureo-pubescente, segmentis dorsalibus 4 basalibus fasciis apica- 
libus distinctis; area pygidiali angusta, pallidissime aureo- 
pubescente; tegulis testaceis, segmentis abdominalibus margine 
apicali anguste brunneis; tibiis, tarsis, femoribusque posticis 
ferrugineis; alis hyalinis, venis fusco-ferrugineis. 
Long. 9 mm. 
9. Eyes separated on the vertex by a distance equal to 
the length of the two basal joints of the flagellum; clypeus 
subtruncate at the apex, the apical margin rather broadly 
depressed; antennz short, the basal joint of the flagellum 
fully half as long as the second, which is a little shorter 
than the third; vertex not distinctly punctured. Median 
segment about half as long again as the scutellum, without 
a longitudinal sulcus on the dorsal surface. Abdomen 
rather slender, thinly clothed with short, dull, pale golden 
pubescence, which is denser and brighter on the marginal 
fascie. Pygidial area narrow, nearly twice as long as the 
greatest breadth, narrowly rounded at the apex. Second 
sternite minutely and closely punctured. Only three 
slender spines visible on the basal joint of the fore tarsus. 
Second abscissa of the radius very little shorter than the 
third, longer than the distance between the recurrent ner- 
vures on the cubitus. Third cubital cell much more than 
half as long as the second on the cubitus, extending further 
than the apex of the radial cell. 
Hab. Abyssinia, Harar (G. SHE TFs May. 
Described from a single specimen. It is possible that 
the spines on the fore tarsus may have been broken off on 
the basal part, but the specimen is in good condition and 
shows no signs of damage. ‘The species may be distinguished 
by the narrow pygidial area, the short joints of the flagellum, 
and the small aud slender form.
