164 ARANEIDEA. 
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith?) ; Panama, Bugaba (Champion '). 
I strongly suspect that this species is identical also with Hedana octoperlata, 
E. Simon [Ann. Soc. Ent. Belg. xxxix. p. 439 (1895)]. I here assume that it is at 
least congeneric with it, and in this case it cannot be Erissus, Simon. 
But whether this is the case or not, I cannot regard them as congeneric with Hedana 
gracilis, L. Koch, judging from his figure (Arachn, Austr. t. 12. fig. 1). Moreover, 
M. Simon says [Hist. Nat. Araign. (2) i. p. 1039] that in edana the area of the central 
eyes is much longer than broad, and narrower in front, whereas in Koch’s figure of the 
eyes of Tedana gracilis, the type of the genus, the ocular quadrangle is square. 
It is necessary, therefore, to substitute a new generic term for Diwa puta (= Erissus 
pustulatus), O. P.-Cambr. 
his species is much more likely to fall near Isala, L. Koch; but having no 
examples of that genus at hand, it is not possible to give an opinion which is likely to 
be of any value. The figure, however, of the eyes of Jsala punctata, L. Koch, agrees 
very closely with the position of those in Diwa puta, O. P.-Cambr. 
Subfam. APHANTOCHILINZ. 
Labium exceedingly narrow. Sternum very short, not produced posteriorly behind the cox of the third pair 
of legs. The carapace and abdomen are more or less clothed with cusps or spinigerous tubercles, while 
the anterior portion of the carapace is developed laterally into a horn on each side. Colulus absent or 
almost obsolete. Legs almost entirely devoid of spines; femora covered with scattered tubercles. 
The three genera, confined to Central and South America, may be distinguished as 
follows :— 
A. Central eyes of both rows much further from each other 
than from the adjacent laterals. Femora with apical 
tubercles. 
1. Carapace produced behind, forming a narrow pedicle . . [ApHanrocuitus, O. P.-Cambr.] 
2. Carapace not produced behind . . ~ . . « Masztra, O. P.-Cambr. 
B. Eyes of both rows approximately equidistant, Femora 
without apical tubercles. . . . . . . . . «. « « [Bucranrum, O. P.-Cambr.] 
No examples of the first or last of these genera have hitherto been taken in Central 
America, but their characters are so closely involved with those of Majella that they 
have been added to the ‘Table. 
MAJELLA.

Type M. affinis, O. P.-Cambr. Mexico. 
Maxille very elongate, attenuate towards the apex; labium very long and narrow, but distinct. 
constricted and produced behind. Femora with tubercles on the upperside near the apex. 
of both rows much further (twice as far) from each other than from the laterals.
