071 Habits, ^c. of a Species of Oiketicus. 43 



genus Oiketicus for the present, although I feel convinced that tlie 

 genus Oiketicus, as established by Mr. L. Guilding in the Linnaean 

 Transactions, will not properly admit the so called species of 

 Oiketici from New South Wales and our East Indian possessions. 

 Indeed Mr. E, Doubleday has already created a subgenus for one 

 {Thyrldoptcryx, Stephens) of the clear winged species from Western 

 Australia, in the propriety of which I fully concur. 



Oiketicus elongatus, W. W. S. 



Male. — Head rufous brown, with the eyes black. Antennfe 

 short, of the same colour. Thorax black, with the anterior half 

 rufous brown. Wings sooty black, with the nervures hyaline ; 

 the anterior pair long, narrow, and sharp pointed, the posterior 

 pair about two-thirds the length of the anterior. Abdomen 

 black, tipped with rufous brown, occasionally much elongated, 

 when it appears as if it were black and brown banded. The 

 brown bands are occasioned by the membrane of the abdomen 

 showing itself at the joints. Legs anterior pair rufous brown, 

 the two posterior pairs black. Tarsi black. 



Expansion of wings 2 inches. 



Abundant about Sidney, New South Wales.
