I'AM. BLEPHAROCERID^ 9 



Biology. — Roth males and females have been found. Life-history and immature stages 

 unknown. Schnuse found both sexes at composite flowers, sucking. But the females were probably 

 not there for nectar, but luinting small insects, as they are blood-drinkers. 



Geographical distribution of species. — The single species of the genus is recorded, so 

 far, only from the islands of Corsica and Cyprus.

Characters. — No incomplete vein near the posterior margin of the wings; eyes bisected by 

 an unfacetted cross band or line into a dorsal browmish region of larger facets and a lower black region 

 of smaller facets; no longitudinal vein between the first and fourth veins. 



Biology. — Only the male sex of this genus is known. Life-history unknown. At the Oct. i, 

 1890 meeting of the London Ent. Society a Mr. C. J. Gahan exibited a curious little larva-like creature 

 found by Mr. A. P. Green in a rapid mountain stream in Ceylon, and observed that there was some 

 doubt as to its true position in the animal kingdom. « Thereupon the savants of the Society proceeded 

 to make guesses as to the general identity of this little Ceylonese visitor. Mr. Hampson pointed out its 

 likeness to chaetopod worms (especially because of the parapodia-\\k& lateral appendages) but added that 

 all the known polychaetous worms were marine. Lord Walsingham and Mr. McLachlan expressed the 

 opinion that the animal was of myriapodous affinities, and was not the larva of an insect. After this 

 meeting Mr. Gahan had his specimen examined by Baron Osten-Sacken and Professor Packard, who 

 recognized it as a Blepharocerid larva. As llainniatorhiua bella is the onlv Blepharocerid species so far 

 found in Ceylon Mr. Gahan' s specimen may provisionall v be looked on as the larva of this species. 



Geographical distribution of species. — The single species of this genus is recorded, so 

 far, only from Ceylon.
