PREFACE TO VOL. II 
This volume deals with the rest of the genus Culex and with 
the remaining genera Panoplites, TaeniorhyncJms, Deinocerites, 
Aedes, Aedeomyia, Uranotaenia, Haemagogus, Wyeomyia, Tricho¬ 
prosopon and Corethra and Mochlonyx. 
The two genera Corethra and Mochlonyx are doubtful 
Culicidae. They present so many differences from true Culicidae 
that I feel sure from the limited material at my disposal that 
they should be excluded. The peculiarities in larva, pupa and 
adult are, I think, sufficient to raise them to a distinct family 
between the Culicidae and Chironomidae . But as I have not 
had either sufficient time or material to properly study them, 
they are retained pro tem. in this family. 
A number of new genera are described here; of these Pano¬ 
plites, Deinocerites, Aedeomyia and Trichoprosopon are very 
distinct, and in the Appendix the same may be said of the genera 
Brachiomyia and Limatus. A large amount of fresh material 
has been received since the first volume went to press, the most 
interesting being that brought back by Dr. Durham from Para. 
Amongst his collection were the £ 5 s and 9 s ^ wo species of 
Sabethes, one being new. From these specimens I have had to 
remodel the genus, as I find they are of Aedes type, not Culex , 
£ and 9 having short palpi. The metanotum has also chaetae 
as in the genus Wyeomyia, in fact the 9’ s described in the 
genus Wyeomyia very nearly approach the female Sabethes. 
I think, however, they are distinct, but unfortunately no male 
Wyeomias have been received of any of the species. Of the two 
new genera described in the Appendix, one, Brachiomyia, is very 
marked, the antennae being very long and scaled; the other, 
Limatus, approaches Trichoprosopon on account of the metanotum 
having scales as well as chaetae. A number of larvae have also 
been recently received, including those of Megarhinus.
