CLUBIONA. 195 
CLUBIONA, Latreille. 
Clubiona placens, sp. n. 
Adult male, length 13 lines. 
Cephalothorax broadish oval, broadly and squarely truncated in front; lateral marginal impressions slight, 
convexity moderate, profile-line slightly and continuously curved; height of the clypeus equal to the 
diameter of a fore-central eye. Colour dull orange-yellow, the ocular region, two broad lateral bands, and 
a tapering, elongate, central longitudinal band, from the ocular region to the thoracic junction, of a 
yellow-brown hue. 
Eyes on black spots, in the normal two transverse curved rows; the curves, looked at from above and behind, 
are equal, the convexity of that of the anterior (or shortest) row directed forwards, and of the posterior 
row backwards. The eyes are subequal, those of the fore-central pair smallest, the rest nearly equal ; 
those of the hind-central pair are separated by rather more than each is from the hind-lateral eye on its 
side, or nearly one and a half diameters; the anterior row, with the hind-laterals, form an exact segment 
of a circle, but not quite a semicircle. The interval between the laterals is small, that between the fore- 
laterals and fore-centrals less, and that between the latter (fore-central pair) scarcely more than half 
a diameter. ‘The laterals are of equal size, and rather larger than the hind-centrals. The four central 
eyes form a square whose anterior side is shorter than the rest. 
Legs moderate in length and strength, 4,1, 2,3, armed with long and rather slender spines, and yellow in colour. 
Palpi moderately long, yellow, the digital joint yellow-brown ; cubital joint short; radial joint nearly double 
the length of the cubital, with a small, tapering, sharp-pointed apophysis at its fore extremity on the outer 
side, and two longish spine-like bristles on the inner side ; digital joint elongate-oval, its fore half drawn 
out into a longish somewhat cylindric form, slightly tapering, but obtuse at the end. Palpal organs 
not very complex; a strongish tapering spine springs from the inner side, curves round and over to the 
outer side and again back to the inner side, whence it ends in a fine point beneath the margin of the 
joint ; near the base, on the anterior edge, of this spine is a small tooth-like prominence. 
Falces tolerably long, moderately strong, straight, cut away towards their extremity on the inner side, where 
they are furnished with numerous strong bristly hairs and thinly covered with red-brown granulosities 
in front. Colour yellow-brown. 
Mazille and labiwm normal in form, colour yellow-brown. Sternum yellow. 
Abdomen oval, pointed behind, truncate in front, thinly covered with grey hairs; pale dull yellow in colour, 
with a series of five or six pairs of rather elongate oblique brown spots (being the remains of the normal 
angular bars or chevrons) on the hinder half of the upperside, and some indistinct brownish markings on 
the fore half. Spinners normal, yellow. 
Hab. Panama (Sarq). 
Clubiona simplex, sp. n. 
Adult male, length 33 lines. 
This spider is of normal form and appearance. The cephalothorax, legs, and palpi are pale orange-yellow, the 
former clothed with greyish hairs ; falces dark reddish-yellow-brown ; maxille and labium yellow-brown, 
sternum yellow, and abdomen luteous-yellow. 
Eyes in normal position, the quadrangle of the four centrals broader than long, and the anterior side narrower 
than the posterior. The fore-central pair are larger than the fore-laterals, and largest of the eight; the 
rest subequal, the hind-centrals perhaps smallest. The height of the clypeus is very small, the fore-central 
eyes being almost close to the margin. The interval between the hind-centrals is considerably greater 
than that between each and the hind-lateral eye next to it. 
Legs moderately long and strong, 4, 2, 1, 3, not greatly different in length; a thin scopula beneath the tarsi 
and anterior portion of the metatarsi of the first two pairs; spines normal. Each tarsus ends with a 
compact claw-tuft springing from a very distinct supernumerary (or claw) joint. 
Palpi moderately long, rather strong. The humeral joint has three not very long but strongish pale spines of 
equal length in a short transverse row near its fore extremity on the upperside, and a little way behind 
them a single spine, longer and rather stronger. Cubital joint short, somewhat tumid in form above
