THE NEUROPTEROID INSECTS OF 

 BARKUDA ISLAND. 



By Cedric Dover, Assistant, Zoological Survey of India. 



Under this convenient title I propose to give a list of the 

 various net-winged insects other than dragouflies and termites at 

 one time included in the order Neuroptera, that have been taken 

 on Barkuda. The Myrmeleonidae are the only family at all well 

 represented on the island Three species of Palpares, and two of 

 Acanthoclisis only were captured, but it is probable that a few 

 smaller species belonging to other genera also occur. All the 

 species have been carefully compared with authentically named 

 specimens in the collection of the Zoological Survey of India. 



Family Ephemeridae. 



An Ephemerid is abundant in the rains, breeding in the lake 

 and in the pond. It is probably a species of Caenis. 



Family Hemerobiidae. 



The only Hemerobiid taken on the island is a species of Sisyra 

 on which Dr. Annaudale remarks : " The insect is certainly a Sisyra, 

 but is distinct from the only described Indian species, 5. indica 

 Needham'. Its larva is parasitic on the sponge, Spongilla alba, in 

 the pond on Barkuda, but leaves the water before pupating and 

 spins a small cocoon on a blade of grass or some similar situation, 

 often at a distance of several yards from the edge of the pond." 

 Note:; on the association of Indian Sisyra with sponges are given 

 by Annandale in Joiirn. As. Soc. Ben.o. (n.s.) If, p. 194, rgo6. 



Family Myrmeleonidae. 

 Acanthoclisis horridus Wlk. 



Barkuda, 2 examples, 13-19-1x19 (Gravely). 



Represented in the collection of the Zoological Survey of India 

 from Cherria Island in Lake Chilka and Sibsagar in Assam. The 

 species is fairly common on Barkuda, being found generally on 

 the foliage or branches of the pipal tree (Ficus religiosa). 



Acanthoclisis edax Wlk. 

 -Barkuda, i example, viii-19 {Gravely).
