52 _ ARANEIDEA. 
Banks records two specimens from Mexico which he doubtfully refers to this 
species. 
5. Scytodes mexicana. 
Scytodes mexicanus, Banks, Proc. Calif. Acad. Sci. (3) i. p. 210, t. 18. fig. 1°. 
Hab. Mexico, Mexico city (Banks '). 
6. Scytodes perfecta. 
Scytodes perfecta, Banks, Proc. Calif. Acad. Sci. (3) i. p. 210, t. 18. fig. 2°. 
Hab. Mexico (Banks ?). 
To judge from Banks’s description and figure, this species is quite distinct from 
S. longipes, Luc. 
Subfam. LOXOSCELINA. 
Colulus present between the anterior spinners. Anterior row of eyes very strongly recurved ; lateral eyes 
almost in contact. Tarsal claws two, set on a short onychium. Clypeus oblique, porrected. External 
side of mandible finely striate. Inner side of femur of palpus set with one short stridulatory spine. 
Mandibles with a membranous lip on the outer side at the apex. Palpus of female without a claw or 
claw-like appendage at the apex. Anterior margin of maxillz strengthened by a chitinous rim, finely 
serrulate. Carapace compressed, convex, not raised behind. Central thoracic groove very deep and well 
marked. Body and legs clothed with fine hairs. 
The eight or ten species falling into this subfamily are closely allied and widely 
distributed. The habits of the spiders are somewhat like those of Scytodes. They 
live under stones and bark of trees or in the crevices of the walls of houses or any 
other convenient cranny. The web is white, flocculent, and adhesive, irregularly 
spread over the inside of the retreat, the cocoon being attached to one or other side of 
the domicile. They crouch at the entrance of the den and venture out a little distance 
at night, rapidly retreating if alarmed.
