A NEW MOSQUITO FROM NOllTHERN CHINA. 7 

 By Fred. V. Theobald, M.A., F.E.S., &c. ^ 



X SMALL collection of Culicidae sent me by Dr. Brouquet, of 

 Tien-Tsin, contained a long series of Myzorhynchus sinensis, 

 Wiedemann, showing considerable variation in size, but most 

 constant in markings ; a single female of Culex hiroi, Theobald ; 

 and a female of C. pseudoinfula, Theob., and an undescribed 

 species, which I have called Grahliamia broquetii. They were 

 all taken in the Arsenal de I'Est, Tet-chili, North China. 



Culex pseudoinfula, Theob., I described from Pasuruan, Java 

 and Samarang ; the type is in the Amsterdam Museum.
