250 ARANEILDEA. 
tibie of the first and second pairs two only in a longitudinal line on the anterior half, and beneath 
the metatarsi two only in a transverse line near the base. 
Falces moderate in length and strength, conical, vertical. 
Palpi. Terminal claw very minute. 
Mazille straight, rather long, considerably widened at the extremity, and rather strongly, but broadly, 
impressed transversely. 
Labium oblong, rather narrowed, and rounded at the apex. 
Sternwm much longer than broad, truncated transversely before, obtusely pointed behind. The coxe of the 
fourth pair of legs almost meet at this point. 
Abdomen oblong-oval ; inferior spinners longer, stronger, and much wider apart than the superior spinners. 
Bonna fidelis, sp. n. 
Adult female, length 34 lines. 
Cephalothorax dull, pale yellowish-brown, the sides and a V-shaped marking just in front of the slight, narrow, 
thoracic indentation suffused with dusky brown, deepening into a narrow black marginal line. 
Eyes of nearly uniform size ; the interval between the fore-centrals is double that between each and the fore- 
‘lateral eye next to it; the interval between those of the hind row is equal. 
Legs similar in colour to the cephalothorax. 
Palpi, falces, and mawille similar to the legs in colour. 
Sternum similar to the legs in colour, but much marked and suffused, excepting in the middle, with blackish. 
Abdomen brownish-black ; on the upperside the fore half or rather more is almost covered with a longitudinal, 
pale, dull yellowish, oblong marking, as broad as the abdomen in front, narrower behind, where, towards 
the end, there is a notch or indentation on each side, giving the hinder end a somewhat fish-tail form, the 
hind margin being also indented, and with a short longitudinal line from its centre connecting it with a 
series of transverse angular pale lines or chevrons; these decrease in vividness and become obsolete 
towards the spinners; the spinners are similar in colour to the cephalothorax. The underside is rather 
paler than the upper. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
BEDRIACUM *, gen. nov. (fam. Drasside ; subfam. Clubionine). 
Cephalothorax longer than broad; lateral marginal impressions moderate and near the anterior margin of 
the caput; moderately convex, rather highest at the thoracic indentation. 
Eyes rather closely grouped together ; the anterior row is shortest, and has its convexity directed forwards, the 
convexity of the posterior row directed backwards, the fore-centrals much the largest. The four central 
eyes form a square or very nearly so. ‘Ihe eyes of the posterior row are equally separated ; those of each 
lateral pair contiguous to each other. 
Legs long, 1, 2, 4, 3, or 1, 4, 2, 3 (2 and 4 scarcely different in length), not very robust, armed with longish, 
not very numerous spines, those on the metatarsi and tibiz of the first and second pairs not confined to 
the underside of the joint. There are also numerous long, slender, prominent hairs on all the legs; tarsi 
furnished with an exceedingly thin scopula. 
Falces rather long and projecting forwards. 
Maxille similar to those of Clubiuna, straight, but widened at the extremities. 
Labium oblong, truncate at the apex; little more than half the length of the maxille. 
Sternum oval, somewhat rounded at the fore-extremity. 
Spinners rather long; those of the superior pair have the terminal joint as long as the basal, almost cylindrical, 
scarcely tapering.
