Division PSITHYRISTRI ARI A 



Psithyristriaria. Distant, Ann. Mag. Nat. Hist. (7), Vol. i5, p. 084(1905), 



Characters, — Head (including eyes) considerably narrower than base of mesonotum, tym- 

 panal coverings as long as but very much narrower than the orifices, which are thus inwardly exposed; 

 abdomen narrowed posteriorly, a little longer than the space between the apex of head and base of 

 cruciform elevation; tegmina and wings hyaline ; tegmina with the venation abnormal; apical areas 

 eight, the lower one very small ; ulnar areas much compressed, broad, especially the two lowermost. 



According to our present knowledge the Psithyristriaria are confined to the Philippine Islands.
