ME. E. M'lACHLAN ON A SYSTEMATIC 



Hab. Egypt, Syria, South Caucasus, Persia. 



Genus Thelepeoctophylla *, Lefebvre. 



Wings rather narrow, slightly dilated in the middle, not appen- 

 diculate ; the posterior pair much smaller than the anterior : 

 network open: transverse branch of the lower cubitus con- 

 fluent with the postcosta. 



Antenna one-fourth shorter than the wings, without verticillate 

 hairs in the basal portion ; club short and subtriangular : a 

 very dense tuft of hairs between the basal joints and on the 

 face. 



Eyes with the lower division one-half smaller than the upper. 

 Thorax slightly villose. 



Abdomen short, in the <$ furnished with two long, hairy, forci- 

 pate, superior appendices, provided internally with a tooth in 

 the middle • and two short and stout, hairy, inferior appendices : 

 in the $ with a pair of very large, curved, and foliaceous (de- 

 ciduous?), membranous, superior appendices, and two very 

 short, hairy, inferior appendices. 



Legs with the spurs of the posterior tibiae about the length of 

 the first tarsal joint. 



Hab. Coast of the Mediterranean. 



The single and familiar species of this genus bears, in the 

 formation of the eyes and abdominal appendices, and in the short- 

 ness of the tibial spurs, characters so trenchant as to preclude 

 the possibility of error.

Genus Siphloceeus, n. g. 



Wings elongate, narrow, scarcely dilated, the extreme base of 

 the inner margin of the anterior pair with a slight excision, 

 not appendiculate : network rather close ; transverse branch 

 of lower cubitus confluent with the postcosta in all the wings. 



* Lefebvre writes " Deleproctophylla" and professes to derive the first part 

 of the name from " drjXia (femelle)" an incomprehensible misreading of OrfXia. 

 Rambur very properly corrected this error.
