Among the new genera lately separated by Theobald from ^des and 

 Uranotcetiia, the differences seem at times puzzling, and without an 

 opportunity to study the types, it is not always easy to feel sure of the 

 position of a new insect. It is also to be noted that in some of these 

 genera the male is unknown, and it may possibly happen that they belong 

 to the class having long palpi in the male. This is very definitely 

 suggested by a mosquito received recently from Bayamban, Pangasinan, 

 P. I., which, while having long palpi in the male, flat scales (no curved 

 ones) on the head, curved scales only on the scutellum, still has the wing 

 characteristics of Uranotcznia. From most of the new genera it is cut off 

 by the wing and the long palpus, but it evidently lies near Mimomyia, if 

 Mimomyia belongs to the long-palpied group, the main differences being : 



I St. The shape of the scales on the mesonotum, which in this insect 

 are, so far as I can determine, simple slender curved scales ; more 

 slender than those on Stegomyia fasciata, Fabr., but showing no 

 truncated ends. 



2nd. Base of ist submarginal is exterior to that of 2nd posterior. 



3rd. Position of cross-veins, which in this insect are typical U'ra?io- 

 icEuia veins. 



Variability of cross-veins has, however, now become proverbial, and 

 while the other diff"erences constitute good specific values, they hardly 

 seem, even considering the scale shapes on the mesonotum, sufficient to 

 warrant creating a new genus, and I am therefore placing it, provisionally 

 at least, under Mimomyia. 



Miftiotnyia Chafuberlaini, n. sp. — Male: head light, heavily covered 

 with light yellow, almost white iridescent flat scales, a few brown forked 

 scales on the occiput extending well around to the sides; two large bristles 

 projecting forward between the eyes, four or five around the eyes; antennae 

 brown, very plumose, light banded, basal joint bare, dark, verticels brown, 

 but giving light (tow-coloured) reflections with a suggestion of orange ; 

 proboscis orange, tip black ; palpi longer than the proboscis, mostly 

 yellow-scaled ventrally, but partly brown-scaled dorsally, a dark band at 

 the apex of the penultimate joint, and the ultimate joint clubbed (suggest- 

 ing some of the Anopheles), and quite dark at the tip ; clypeus yellow ; 

 eyes brown and silver.
