Length 1| millim. 



Described from one male in the Indian Museum, from Kurseong, 

 Darjiling, 3. vii. 08. 



The antennae of the type-specimen are somewhat injured, with 

 the result that some of the joints appear to be enlarged ; at first

 different genus, but for the present I leave it in Sciara. Beyond 

 this damage and a slight crushing of the thorax by the pin, the 

 specimen is perfect.
