Division OESILLARIA. 



Orsillaria, StSl, Ofv. Vet.-Ak. Fork. 1872, no. 7, p. 43 ; En. Hem.

Hemelytra either colourless or greyish-subhy aline ; apical margin 

 of corium near apex of clavus sinuate. 



The genus OrsiUus, which is the foundation for the name of this 

 division, is at present known only from the Palsearctic Region.

Type, JS'. zealandicus, Dall., from New Zealand and Tasmania. 



Distribution. Almost universally distributed. 



Head triangular, rather broad ; eyes prominent, projecting 

 beyond the anterior angles of the pronctum ; basal joint of the 

 antennae a little shorter than the head, second generally longer 

 than the third ; rostrum reaching or nearly reaching the posterior 

 coxae, basal joints not extending beyond base of head ; body 

 oblong ; membrane with five veins, the two inner ones transversely 

 united ; anterior femora unarmed. 



I can enumerate only three species from British India, and many 

 more cannot be anticipated ; as although the genus is widely 

 distributed, its species also have a wide range, and in no area, 

 beyond the Palaearctic, do they appear to be numerous, though 

 individuals are abundant.
