ARIADNA. 43 
The members of this subfamily live in tubular retreats, usually constructed in the 
crevices of the woodwork of buildings or in the corners of window-frames, and sit with 
the anterior pair of legs exposed at the entrance of the funnel.

Fam. CAPONIIDZ. 
Eyes two. Lung-sacs absent. Two pairs of tracheal stigmata, adjacent, close to the genital rima. Mandibles 
not soldered together. Sternum without sigilla. Spinners six, anterior pair wide apart, separated by at 
least four diameters; the four anteriors set in a transverse straight line. Colulus absent. Calamistrum 
and cribellum absent. Tarsal claws variable, two or three. External side of mandibles striate. Femur 
of palpus with a single stridulatory spine towards the base on the inner side. 
The spiders included in this family are, with one exception, confined to the Antilles 
and the northern regions of South America. It is highly probable, however, that the 
genus Mops, Macl., will be found to extend to the Isthmus of Panama, NV. glauca, 
v. Hasselt, having been recorded from the islands of Buen Ayre, Oruba, and Curagao, 
off the coast of Venezuela; we therefore figure the structural details of a species of 
this genus, WV. coccineus, E. Simon, from Venezuela, the type of which is in the British 
Museum. (See Tab. III. figg. 7, 7a-f, 2.) 
A. Tarsal claws two only on tarsi i. and ii., three on tarsi iii. and iv. Tarsi 
of all four pairs bisegmentate. Tarsi i. and ii. with a membranous 
appendage at the base beneath. Protarsi i. and 11. with a thin mem- 
branous lamina extending longitudinally beneath the joint. Sternum 
not prolonged between the coxe of the fourth pair of legs, its apex 
quite distinct from the post-sternal plagula. Epigynal area not coria- 
ceous. Maxille less elongate and less attenuate at the apex . . . ~ [Nops, Macleay.]
