A NEW MOSQUITO FKOM NORTHEKN CHINA. 

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



A small collection of Culicidae sent nie 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 biroi, Theobald ; 

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

 species, which I have called Grabhamia broquetii. They were 

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



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

 and Samarang ; the type is in the Amsterdam Museum.

 chestnut-brown line and a similar coloured area in front of the wings 

 at the sides. Abdomen mostly white scaled, but with four pairs of 

 black quadrangular marks, decreasing in size from the base apically.
