I believe the Mosquitoes will be found to rival in number of species 
any of the other dipterous families, for every collection sent me brings 
new species. Of the known species only some seventy occur in the National 
Museum at Budapest, but although the collection is small it is rich in 
types. Most of the new species have come from New Guinea and other 
neighbouring Islands, the Malay States, Bolivia and Peru, countries (ex¬ 
cept Malay) from which I had not previously seen any Mosquitoes. 
In describing the new species I have followed the same plan as 
that adopted in my «Monograph of Culicidæ». 
Not only are new species described here, but also some previously 
known ones which I had not seen before, so as to have uniform descrip¬ 
tions of all the known species drawn up for comparison. 
Amongst the latter are Cui ex vexans Meig., Culex modestus Fie. 
and Grabhamia pulcritarsis Bond. The collectors name is given in 
brackets and also the date of capture when such has been recorded on 
the labels. 
I have also added in small print the general distribution of each 
species. The types are in two forms (I) pinned specimens and (II) balsam 
preparations to show minute structure, such as wing-scales, ungues, 
palpi etc. 
The following genera are represented in the National Collection : 
Anopheles Meig., Myzorhynchus Blanch., Myzomyia Blanch., Cellia 
Theob., Megarrhinus Bob.-Desv., Toxorhynchites Theob., Mucidus Theob., 
Janthinosoma Arrib., Stegomyia Theob., Scutomyia Theob., Skusea Theob., 
Desvoidea Blanch., Theobaldia Neveu-Lemaire, Culex Linn., Melano- 
conion Theob., Grabhamia Theob., Taeniorhynchus Arrib., Mansonia 
Blanch., Phoniomyia Theob., Aedes Meig., Uranotaenia Arrib., Sabethes 
Bob.-Desv., Sabethoidés . Theob., Dendromyia Theob., Aedeomyia Theob., 
Joblotia Blanch., Finlay a Theob., Gorethra Meig. 
To these I now add seven new genera : Kertészia, Birónella, Lepido- 
tomyia, Lophoceratomyia, Trichopronomyia, Leptosomatomyia and Poly- 
lepidomyia. Thus with the seven new genera the collection has repre¬ 
sentatives of thirty five genera out of seventy that have been described. 
By far the most interesting specimens are those coming in the new 
genus Lophocer atomy ia in which very peculiar structures occur on the 
antennæ of the d 1 . What their function is cannot even be guessed at, the 
structures are clearly altered and modified verticillate hairs. 
The following is a list of genera and species found in the collection :
