454 ARANEIDEA. 
lacerta, O. P.-Cambr., are placed under Araneus, while T. nodosa, O. P.-Cambr., is 
referred to Cyclosa. Both T. nodosa and T. walckenaert present most distinctly the 
very character by which the Cyclosee are separated as a subfamily from the Aranee, 
viz. the division of the cephalic region, in the female sex, from the thoracic, by “un 
profond sillon entier et semicirculaire,” and they are at any rate congeneric with 
T. nodosa if this character be any criterion. 
With regard to the present characterization of the various groups of the subfamily 
Araneine, it must be treated as merely provisional, until a more complete examination 
can be made of the genera and species from other parts of the world. Furthermore, 
it is almost impossible to judge of the generic affinities of many of the species unless 
examples of both sexes are available for examination. I have been compelled, 
therefore, to separate those that fall into distinct genera, and to place the other 
species at the end. The name Aranea now takes the place of Epeira. 
There seems to be no reason to doubt that the Araneine will admit of a perfectly 
natural classification into generic groups when some arachnologist has time to devote 
himself to an exclusive study of this enormous subfamily. 
There are no species in the collection before me which, so far as I can judge, fall 
into either of the groups of which Aranea diadema, Linn., and Hpeira cornuta, Linn., 
are types, and therefore the generic names Aranea and Lpeira do not appear in 
connection with the arrangement here adopted for the Central-American spiders. 
The following table, a separate one being required for each sex, gives the characters 
of all the genera I have been able to distinguish :—
