PART II.
The first part under this general title appeared in the Revue
ZoologiqueAfricaine, volume XI, fascicle I, in rgz3. The species
discussedin the present report are based on material received fromthe British Museum (Natural History), through the kindness of Mr,
Eowenos, collected by Dr. S. A. Nrlvr in Nyasaland;the Carnegie
Museum, through the kind interest of Mr. KAnr., collected by the Rev,J. A. Rus in Cameroun; the Paris Museum, through the kindnessof Mons. Srcuv, collected in Western Africa by Mr. R. El,r.exsnncrn and Sergt.Blnnre rrnavl and in the collection of the writer,throughthe kind interest of Mr. A. W. ]. Ponarnov,collected in Nigeria, andProf. J. C. Fnunr, collected in Natal. As in the preceding part, keys
to certain of the generaare presented,which, it is hoped, will be ofservice in determining the now involved Tipulid f.auna of. theEthiopian Region,

Genus LECTERIA Osten Sacken.
The genus Lecteria was based upon a single species,L. armillarrs (Flrnrclus) from South America. It was not until tgzo that any
speciesfrom Africa was definitely recorded but since that date nthernumerous species from the Ethiopian Region have been describeduntil at the present time no fewer than 13 speciesare known fromthis region.
The speciesof Lecteriahave the legs conspicuouslyhaity, especiallythose of the f.ema7e,where the trichiae ate erect and very evident.
Venationaltendenciesin the genusate asfollows:Sc very long, lying
close to the tip of Rr at the wing-margtn; Rs usually long and lying
very closeto R, cell rsl Rr thus being very narrowy veins Rs,Rz+s
and Re in perfect alignment, Rz and Ra very strongly divergent
toward their tips, cell Rz at the wing-margin thus being unusuallywide; deflection of R4+b conspicuous, strongly arcuated; cell Mt

-776always pres€nti basal deflection of Culying the fork of M, approximatelyequal to or longer than Cuz.In the speciesof.the af ricana group,
the branchesof M diverge strongly, producing a very deep, hexagonal cell st Mz which is irregular in shape, m alwaysshorter thanthe outer deflection of Ms. The venation is rather uniform throughout
the genus; in L. duehaillui, sp, n., Rs is of rather an unusual length,
being at least three times Rzas.
The Ethiopian Lecteria fall in two more or less natural divisions,the first, which may be called the africana group, including large tovery large species in which the wings ate never cross-banded andtherc arc no spinous setaeat the origin of the basitarsi; this group
includes the following species : africana AtBx., africana nigrilinea
ALnx., atricauda Atnx., pluriguttata Ar,rx., tanganice At-nx., tibi'alis, sp. n,, and uasta Atrx, The second division, which may be tetgroup,includessmallerspeciesin which the wings
med the triacanth.os
are often conspicously cross-banded with brovrn, and the legs areusually variegated with white or yellowish annuli, usually on thetibiaebut sometimesbest indicated on the basitarsi (hirsutipes,meta'
tarsalba and reisi),In a few species(simpsoniand triacanthos)the interspacesbetween the cells are conspicuously dotted with brown. In all
the species,(excepting hirsutipes,in which the cttatacterhas not been
described), one to three spinous setae are developed at the originof the basitarsi, so close to the tibiae as to simulate tibial spurs. The
speciesincluded in this group ate as follows t duchaillui,sp, n., hirsutipesRtnp., laticincta Atex., metatarsalbcAux., simpsoniAlex.,
and triacanlftosAux.
The nearest relatives of. Lecteria arc the genera Clydonodozus
Enornrnrx and ConosiavAN DERWutn, in which the maxillary palpi
are reduced to a minimum.
