smooth and shining. Pronotvun sparsely punctured, the posterior 
margin broadly smooth and shining ; mesonotum and scutellum 
shining, with a few very large punctures, propleurae almost smooth, 
mesopleurae rather sparsely punctured, the sides of the median seg¬ 
ment finely obliquely striated. Median segment almost as long as 
the pronotum, mesonotum and scutellum combined, subopaque, 
almost smooth, with the three usual carinae in the middle, the median 
one not reaching the ape-x, the two lateral ones half as far again from 
each other at the base as at the apex, the margins of the segment 
distinctly raised both at the apex and the sides, a fine longitudinal 
Carina on each side narrowly separated from the raised lateral mar¬ 
gin. Abdomen shining, finely punctured, the two basal segments 
sparsely, the others more finely and closely, the apical half of the 
pygidium smooth ; the basal segment broad, without a transverse 
Carina at the base. Stigma very small, almost absent; first recurrent 
nervure received at the middle of the first cubital cell, second at 
three-quarters from the base of the second cubital cell; second 
transverse cubital nervure strongly curved inwardly. 
Black ; mandibles, antennae and anterior tibiae beneath fusco- 
ferruginous, the apical half of the pygidium pale testaceous ; spines 
of the tibiae and tarsi pale ferruginous ; the pubescence on the 
abdomen and legs whitish. Wings hyaline, tinged with fuscous, 
nervures black. Length TO mm.

Type in Berlin Museum. 
The median segment is unusually long in this species.

The type is from Salisbury, Mashonaland. A specimen 
in the Berlin Museum from Langenburg, Lake Nyassa, 
has the median segment distinctly longer and the pygidium 
rather broader. The species of TipMa are subject to local 
variation, the length of the median segment seeming to be 
especially influenced. If new species are founded on such 
characters before long series are available and both sexes 
known, much confusion may result. I therefore prefer to 
treat the Nyassa form merely as a local race. 
There are at least five species of Tipthia in the collection 
from Langenburg, which may be distinguished by the 
following key to the females :—
