coloration or marking, not only are genital features to be found 

 but also the character of the antennal annulation, cephalic, pro- 

 notal and tegminal color pattern and general coloration, afford 

 excellent diagnostic features. In a number of these species, 

 general size and form and width of tegmina prove to be of ex- 

 cellent value in further distinguishing the species. 



NOMENCLATURE. 



The names, 3 in the order in which they have been proposed, 

 are, for the plain green species : nivea, chlorotica* viridis, 

 mrescens, 5 *exoleia, *prasina, *cubensis, antillarmn, 6 poeyi, 7 

 glanca, 8 peruana, luteola, lancadon, *thalassina, punctum. 



For the species having the antennae annulate and the pro- 



3 An asterisk before a name in the present list indicates that the 

 species is represented in the material before us without question of de- 

 termination. 



4 This name must be considered unidentifiable. The original de- 

 scription and figure are both wholly inadequate for locating the species. 

 The type is no longer in existence and was described from the Cape of 

 Good Hope, a locality either in error or the type was an adventive 

 specimen, for none of the plain green species of Panchlora are found 

 native in Africa. In any case, description, figure and locality, all are 

 valueless. 



5 Shelford, who has examined the types of both nivca and vircsccns, 

 places the latter name in the synonymy under nivca. 



6 This name is an evident synonym of cubcnsis; the description shows 

 no feature of real diagnostic value. In the extensive series before us 

 from the West Indies, but a single species of plain green Panchlora 

 is found. 



7 This name is also a synonym of cubcnsis, (see footnote 6). The 

 type is a male, the types of cubcnsis and antillarum females ; the sexual 

 differences led Saussure to describe the present specimen as distinct. 



8 Brunner has, in our opinion, correctly synonymized this name 

 with prasina. Saussure and Zehntner have resurrected glauca in the 

 Biologia, with apparently only the type of that species before them, 

 giving there for the first time "oculi plus quam eorum latitudine re- 

 moti" as is true for prasina. The name glanca was evidently based on 

 a small example of prasina, showing an unimportant variation in the 

 subgenital plate. We have now before us an example of prasina 

 larger than any other specimen in our series of the genus and other 

 smaller specimens of which the smallest is no larger than the type of 

 glauca.
