TEMECULA,—DICTYNA. 171 
lobe at its base on the outer side, well clothed with coarse hairs. Palpal organs prominént and well- 
developed but simple, consisting chiefly of a large roundish corneous lobe, with an inconspicuous fine 
black tapering spine beneath their fore extremity. 
Falces long, moderately strong, straight, and of a dark slightly reddish-brown colour. 
Mawille, labiwm, and sternum ‘deep blackish-brown, the two latter having their extremities of a pale brownish- 
yellow hue. 
Abdomen rather small, oval, blackish, clothed thinly with coarse hairs. Spinners deep brown, with pale tips. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
*“* Found under a stone in a dark wood.”’ 
DICTYNA, Sundevall. 
Dictyna parietalis, sp. n. 
Adult male and female, length 1} lines. (A slight variation from this, both in respect to deficiency and excess 
in different individuals.) 
Cephalothorax considerably longer than broad, lateral marginal indentations at the caput very strong; thorax 
almost circular; marginal profile of caput (looked at from above and behind) prominent in the middle ; 
caput (especially the occiput) much elevated above the thoracic level. Colour dark yellow-brown, the 
normal indentations clearly defined by converging blackish bars. The upper part of the caput is thinly 
clothed with coarse white adpressed hairs, arranged in 3-5 longitudinal lines. 
Eyes in normal position ; the four centrals form a quadrangle whose posterior side is slightly longer than the 
anterior side. The interval between those of the hind-central pair is rather over an eye’s diameter, and much 
less than that between each and the hind-lateral eye next to it. he fore-laterals are largest, and the 
fore-centrals, which are the smallest, are half the distance from them that those are from each other. 
The height of the clypeus, which is rather prominent below, is rather greater than half that of the 
facial space, and jt has on it some pale spine-like bristles on either side directed inwards. 
Legs rather short, not greatly unequal in length, moderately strong, 1, 4, 2, 3; uniform pale yellow in colour, 
furnished with coarse whitish and other hairs only. 
Palpi short, similar to the legs in colour. Cubital and radial joints short, the cubital strongest ; the outer side 
of the latter is protuberant, ending with a black serrate-edged corneous prominence, somewhat obliquely 
truncated, and near it are some minute tubercles bearing short bristles. The radial joint has a promi- 
nence in front at the base towards the inner side furnished with bristly hairs, terminating in a small 
corneous point. The outer side of the radial joint is also strongly and obtusely prominent, and furnished 
with a few minute tubercles and bristly hairs in an encircling line. The digital joint is large, oval, somewhat 
produced at its extremity, with a small protuberance at its base on the outer side. Palpal organs promi- 
nent, consisting of a large oval lobe, with a twisted corneous process at their posterior extremity pointing 
beneath the radial joint. 
Falces long, strong, of normal form, very prominent at their base in front, upturned and divergent at their 
extremity, greatly excavated and hollow on their inner side; at the base on the outer side in front is a 
strong obtusely prominent process, directed downwards and outwards. On the front of the falces are 
numerous granulations or minute tubercles and impressed points or pock-marks. The fangs are minutely 
serrated on their inner margins. Falces similar in colour to the cephalothorax. 
Mawille and labium normal; similar to the fangs in colour or paler. 
Sternum yellowish, a little darker than the legs, broad-oval, truncate before, and with its posterior extremity 
drawn out into a short obtuse point between the cox of the fourth pair of legs. It is very convex and 
covered with numerous coarse erect pale hairs. 
Abdomen oval, of a dull luteous hue, covered pretty thickly with minute cretaceous white spots, and clothed 
rather densely with white and black hairs intermixed, the latter being of a flattened somewhat narrow 
lanceolate form. On the fore part of the upperside is a longitudinal central black triangular marking, 
strongly constricted or indented in the middle on each side, almost dividing it into two parts; from the 
middle of the posterior margin is a small prominent point directed backwards, giving it a cruciform shape.
