There can be no doubt but that many African species ofTrentepohlia answer the brief characterization of T.fragillima(Westwood). Mr. Edwards informs me that the type of thelatter is not now in the Hope Collections in the Oxford
Museum and may no longer be in exislence. The present
species differs from T.fragillima in the conspicuously larger
size and the coloration of the abdominal and thoracic
sternites. The degree of whitening of the tibial tips inT. fragillima is not known. I take pleasure in naming thisfly after tile collector~ Mr. R. A. Dummer.

pleural appendages at the end, these latter flattened, theposterior margin at the base with a few stout black spines.
JFemale.--About equal in size of body to the male, but thewings smaller and the legs very small and slender. The
abdomen is greatly distended with large eggs, which condition, together with the delicate nature of the wings,
probably renders this sex flightless, at least until ovipositionis accomplished. All of the females available for study are
teneral, the wings being pale and badly folded~ the venation
less distinct than in the male but agreeing in all essentials.
Tile teneral nature of the females would lead us to believethat copulation takes place while the female is still teueral,a condition found in many other Tipulidm. Ovipositor withthe valves very small and fleshy~ the sternal valves extending
beyond the tergal ones.

This very interesting species is dedicated to its collector,
my friend, Mr. H. K. Munro. The collector's full notes on
this species are of unusual interest.
" Found on Ambleside near Port Shepstone on steep hillside, some distance from river. Conditions very dry--rain
had not yet begun. Hillside covered with original bush andtrees, undergrowth not very dense. Ground covered thickly
with dead leaves. Large numbers of this fly were observed,
most of them flying very close to the ground, in fact
touching the dead leaves, so that it was not possible to catchthem by beating without getting so many leaves that theflies, which were very fragile, were ruined. A few were
flying up among the bushes. I soon observed that all thoseflying were males, except only a very few females flying ' incop." After watching them for some time I noticed theflying males congregated in indiscriminate mgldes in certain
spots. When these were examined, I saw that on the groundat each spot was a female with a very greatly distended
abdomen. One male was in copula and the rest were flying
around.
" T h e legs of the males are longer than those of thefemales. Like many of the Tipulid~% individual iJ~sects
were hard to follow owing to their very light and cob-webby
appearance."~H. K. Munro.
