EPEIROTYPUS.—META. , 135 
Hab. Guatemaa, Senahu (Sarg). 
This spider, which is allied to both Theridiosoma, Cambr., and Ogulnius, Cambr., is 
even nearer to the true Epeirids than the former of these two; it also comes near the 
genus Mesopneustes, Cambr. (anted, p. 126). ° 
ARGYROEPEIRA, Emerton. 
Argyroepeira mesomelas, sp. n. 
Adult female, length 2} lines. 
The general form and structure of this spider is normal. 
The cephalothorax is dark brown, as are also the falces, maxille, labium, and sternum. 
Eyes normal; the four centrals form a square, the two anteriors, as well as the lateral pairs, seated on small 
tubercular prominences. 
The legs are slender, not very long, 1, 4, 2,3, 4 and 2 being nearly equal; their colour is yellowish-brown, 
the tibie paler, the anterior extremities of the femora, genux, and tibia dark brown; they are furnished 
with short fine hairs, but are entirely destitute of spines. 
The abdomen is large, subcylindrical, greatly produced forwards, and projecting almost entirely over the cephalo- 
thorax (viewed in profile, there is nearly as much of the abdomen in advance of the pedicle as behind 
it). Its colour is a shining jet-black, marked on the sides with two or three silvery dashes or markings, 
the anterior one, near the fore extremity, being curved and directed to the upperside, towards the 
hinder part of which are one or two oblique silvery stripes on each side, with a central longitudinal one 
at the hinder extremity. Spinners dark brown. Genital aperture small but characteristic in form. 
Hab. Mexico, Teapa in Tabasco (1. H. Smith). 
META, Keyserling. 
Meta flava, sp. n. 
Adult male, length 24 lines. 
The whole of the fore part of this spider is yellow ; the femora of the first pair of legs tinged on the posterior 
half with yellow-brown, and a small portion at the anterior extremity of the tibie of the Ist, 2nd, and 
3rd pairs of legs more or less dark yellow-brown. The cephalothorax also has the thoracic and cephalic 
indentations, and two longitudinal parallel lines from the hind-central pair of eyes, dusky yellow-brown. 
The cephalothorawv and other parts are of normal form. 
The eyes are on black spots, subequal, and in the usual general position. The posterior row is nearly straight, 
the anterior row much curved, the convexity of the curve directed forwards. The interval between the eyes 
of the hind-central pair is rather less than a diameter, and less than that between each and the hind- 
lateral eye nexttoit. The four central eyes form an oblong trapezoid, whose anterior side is longer than 
the posterior. The height of the clypeus is nearly equal to the diameter of one of the fore-central eyes. 
The legs are moderately strong, 1, 2, 4, 3, the first two pairs long, the tirst longest, the third and fourth pairs 
much the shortest. They are furnished thinly with moderately strong black spines, and rather densely 
with short, fine, erect, pale hairs. 
The palpi are short and slender. The digital joint and palpal bulb are large. The palpal organs are highly 
developed, prominent, and complex, and have a strong prominent irregular corneous process at their base, 
almost in contact with another strong prominence at the posterior extremity of the digital joint; this latter 
prominence has a rather irregular termination; at the extremity of the palpal organs is a strong, coiled 
dark spine, with a small one within its coil. 
The abdomen is oval, of a uniform luteous-yellowish hue, clothed with fine erect pale hairs, and covered thinly 
with small, roundish, silvery-white and yellowish spots, leaving, however, the form of the dorsal vessel clear, 
the latter tapering backwards, of a deeper duller colour, and emitting some short lateral lines frum its 
posterior half.
