GENUS PH^NOGLYPHIS. 235 



Generic Synopsis. 



1 (2) Parapsidal furrows distinct. Phsenoglyphis. 



2 (1) Parapsidal furrows absent. Allotria. 



Foerster adopts more " genera" than I have. The 

 following table will explain the " genera " as adopted 

 by this entomologist. 



1 (4) Parapsidal furrows distinct. 



2 (3) Parapsidal furrows complete, one or two fovese at base of 



scutellum. Ph&noglyphis. 



3 (2) Parapsidal furrows incomplete, no fovea at base of scutellum. 



Hemichrisis. 



4 (1) Parapsidal furrows absent. 



5 (6) Wings not so long as the abdomen, without radial cellule. 



Pezophycta. 



6 (5) Wings as long or longer than abdomen, and with a radial 



cellule. 



7 (10) Radial cellule closed in front. 



8 (9) Wings shortened, not or scarcely longer than abdomen. 



Nephycta. 



9 (8) Wings complete, much longer than the abdomen. Allotria. 



10 (7) Radial cellule open in front. 



11 (12) Radial cellule open at the apex, owing to the radial nervure not 



reaching the costa. Dylita, 



12 (11) Radial cellule closed at the apex. Alloxysta. 



Thomson (Opusc. Ent., 811) divides Allotria into 

 three sub-genera: Auloxysta (= Ph&noglyphis), Glyp- 

 toxysta (= Alloxysta), and Allotria. 



Genus PH^NOGL YPH i s . 



Phtenoglyphis, Foerster, Yerh. z.-b. Ges. Wien, xix, 338. 

 Auloxysta, Thomson, Opusc. Ent., 811. 



Mesonotum with the parapsidal furrows complete or nearly so ; 

 scutellum with one or two fovese at the base ; mesosternum with a longi- 

 tudinal furrow. Radial cellule closed on fore margin ; areolet complete. 

 The third joint of antennae in sinuated. 



Foerster makes no mention of PhdsnoglypMs having 

 a longitudinal furrow on the mesopleurae, and I cannot 

 make out, owing to its bad condition, if one is present 

 in P. xanthochroa, but it is certainly present in P. 

 forticornis. Further, he states that the radial cellule
