MESOZOIC INSECTS OF QUEENSLAND, vii., 



area of the tegmen as in Chiliocycla. In Text-fig. 3, I have 

 shown portions of the tegmen of Philagra sp., contrasting a 

 tuberculate area (a) with a normally pitted area (b) . In a, 

 each tubercle carries a short hair set in a definite socket, along- 

 side of which there is a minute circular area devoid of pigment, 

 probably representing a small gland containing fluid and open- 

 ing at the base of the hair. I would suggest that the tubercles 

 of Chiliocycla only differ from those of Philagra in their greater 

 abundance and regularity of arrangement, and in being all of 

 about the same size, those of Philagra being unevenly distributed 

 and varying considerably in diameter. No systematic value can 

 be placed upon the presence of these tubercles as regards the 

 family relationships of Chiliocycla, as they appear to crop up 

 almost anywhere within the Hemiptera.
