154 ARANEIDEA. 
the first and second pairs yellow-brown, dark reddish-brown on the fore-sides ; the fore half and base of 
the tibiw, and in a less degree the fore part of the metatarsi, are also dark yellowish-brown. The legs 
of the third and fourth pairs are pale yellow. 
The palpi are short, yellow. The radial is rather longer than the cubital joint, and has at its extremity a 
small slightly tapering apophysis, whose extremity is somewhat obliquely hollow-truncate. The digital 
joint is of moderate size, oval, pointed at its extremity, and has a semitransparent pointed curved process 
at its base on the outer side projecting prominently beneath. and as long as the radial apophysis. Palpal 
organs simple, not very prominent, their outer margin encircled with a black filiform spine. 
The mawille and labium are yellow-brown. The sternum yellow. 
The abdomen is short-oval, roundly truncate before and rather flattened above; it is of a pale brownish-yellow 
colour on the upperside (which is of a somewhat coriaceous appearance), margined with white, and with 
a very few red-brown points and long bristly hairs. The five normal impressed spots are a little darker 
than the rest of the surface. Near the hinder extremity is a largish, deep red-brown, well-defined marking, 
strongly excavated in the middle in front, and occupying the whole width of that part of the abdomen. 
The sides are marked with some deep red-brown parallel lines. The underside is pale yellow; the 
spinners are short, strong, compact, and immediately in front of them is the transverse opening to a 
spiracular organ. 
Hab, Mexico, Cuernavaca in Morelos (H. H. Smith). 
COLEOSOMA, Cambridge. 
Coleosoma flavipes, sp. n. 
Adult male, length 1 line. 
Cephalothorax of a regular oval form, moderately convex, and equally obtusely pointed at each end. Clypeus 
convex, prominent to the lower margin, but impressed immediately beneath the ocular area, and equal in 
length to at least double the breadth of the ocular area or two-thirds of the facial space. The indenta- 
tion at the thoracic junction is large and of a transverse form. Its colour is deep blackish brown. 
The eyes are moderately large, and do not differ greatly in size; they are grouped tolerably closely together in 
an almost regular transverse crescent form ; the posterior row is nearly straight, and its eyes equally sepa- 
rated from each other by an eye’s diameter or slightly more. The anterior row is shortest and curved, 
the convexity of the curve directed forwards, and its eyes separated by less than a diameter. 
‘The legs are rather long, very slender; pale yellow, with a longitudinal black stripe on each of the femora, but 
the stripe does not run throughout their whole length. They are furnished with hairs and a single long 
slender spine at the fore extremity on the upperside of the genua. The posterior extremities of the tibiee 
of the fourth pair are marked with a conspicuous black blotch. 
The palpi are moderately long, black-brown; the cubital joint is short, bent, nodiform, or roundly prominent 
in front. The radial joint is about equal in length to the cubital, but stronger, being dilated at its 
extremity and somewhat produced on its outer side; these joints are furnished with coarse bristly hairs. 
The digital joint is large, roundish-oval, furnished also with long bristly hairs. The palpal organs are 
prominent, not very complex, and have a strong tapering spine running in a circular form from their 
inner extremity close to their surface, and ending in a fine point near the outer extremity. 
The falces are moderately long, about equal to the length of the facial space, or slightly longer; they are 
straight, tapering, and similar in colour to the cephalothorax. 
The mawille are long, strongest and rather prominent at the base, of a curved form looked at underneath, 
inclined towards the labium, and a little rounded on the outer side at their extremities, which reach 
slightly beyond the extremity of the falces. 
Labium short, broader than high, somewhat subtriangular, though rather roundly pointed at the apex. The 
labium and maxille are like the falces in colour. 
The sternum is of a broad-oval form, convex, and of a darker hue than the cephalothorax ; the hinder extremity 
does not appear to be defined, but runs over into the general covering of the thorax, the width between 
the coxe of the fourth pair of legs being considerable.
