1922.] C. A. Paiva & C. Dover : New Indian Corixidae. 333 



Closely allied to C. affinis, but differing in the nature of the 

 markings on the pronotum. Type in the collection of the Zoolo- 

 gical Survey of India. 



Corixa ribeiroi, sp. nov. 



A single example from Malwa Tal, 3000 ft., Kumaon, VV. Himalayas. 



Head yellowish-white, shining, the basal margin reddish- 

 brown, distinctly longer than width at base between eyes, wider 

 than pronotum, a few scattered punctures on disk of vertex ; 

 eyes black, large, overlapping the anterior angles of the pronotum. 



Pronotum twice as broad as medially long, disk with about 

 six castaneous, transverse lines, posterior margin broadly rounded. 



Elytra ochraceous, rather thickly mottled with castaneous, 

 on the basal claval area the markings are more or less linear and 

 transverse. 



Body beneath and legs ochraceous, posterior tarsi fuscous. 



Length 6 mm. 



I have named this species after Mr. Sydney Ribeiro, the 

 Entomological Assistant of the Zoological Survey of India, in 

 recognition of the assistance he has rendered me in various ways. 

 Type in the collection of the Zoological Survey of India.
