130 HEMIPTERA-HOMOPTERA. 
as certain species of Entylia in their extreme forms come very close to it, and Publilia 
porrecta seems a further connecting form. 
Germar described seven species, and Walker enumerated twelve: these Stal reduced 
to five (including Pudblilia concava) ; but Butler (Cist. Ent. ii. p. 210), after stating that 
he differs entirely from St&l in the synonymy which he gives to the species of the 
genus, reinstates three of Walker’s species and adds two new ones, at the same time 
allowing that he would have no objection to considering the whole of the forms which 
he is discussing as varieties of one inconstant species; this I believe to be the best 
solution of the difficulty. | 
All the species hitherto described are from North, Central, or Tropical South 
America. 
In considering this genus it ought perhaps to be noted that Burmeister (Rev. Ent. 
Silb. iv. p. 181, t. 36. fig. 8) has in some unaccountable way entirely mistaken 
Germar’s characters for the genus, and identified it with what is really Parmula or an 
allied genus.

All the specimens in our collection belong to the form £. inequalis, Butl., except 
four or five which must be referred to his E. mira, and three of a peculiarly coloured 
variety from Chiacam, Vera Paz. Its geographical range would seem to indicate that 
all the forms cannot belong to one species; but large series of specimens from various 
localities require to be examined before the question can be settled satisfactorily, and
