460 ARANEIDEA. 
iii. and iv. yellow, more or less spotted with black; tibie with a conspicuous black apical annulus, 
Abdomen dull yellow above, mottled with brown, with a well-marked central folium, of which the 
second diverticulum is conspicuously dilate at its apex on each side; ventral surface black, with 
the central white line behind the genital rima, and the pair of white spots in front of the spinners. 
3. Colour similar, but paler, on the legs at any rate, the femora, however, being darker. 
Femora i. and ii. in the female with two series of spines beneath, in the male more numerously spined. 
The characters drawn from the spinulation of the legs are applicable only to the adults in both sexes. 
The unca of the palpus is much broader throughout, but especially at the base, than in the two allied species, 
and the blade takes a narrower sweep. The small sclerite (lamina 2) near the base of lamina i. is 
longer, and lies much more adjacent to the denticules on the anterior lobe of the bulb. 
The vulva of the female is characteristic, the scapus (though not abruptly dilate as in M. incrassata) being 
broader throughout than in M. labyrinthea, while the walls of the portule are less prominent and not so 
distinctly separated on their inner side from the base of the scapus as in the latter species.

4, Metepeira incrassata, sp.n. (Tab. XLIII. figg. 11, 1la-e, 2.) 
Type, 9, in coll. Godman & Salvin. Total length 10 millim. 
©. Carapace dull yellow, the central area often deep brown. Mandibles, coxe of legs, and sternum deep 
brown, the latter with or without a central yellow basal line. Legs yellow, femora often suffused 
apically with brown; tibiz with a more or less conspicuous dark apical ring. Abdomen bright ochre- 
yellow, mottled and spotted with brown, the central folium not well defined, especially in front, the 
second diverticula on each side not dilate; ventral area black, with the usual central white line and 
the two spots in front of the spinners. The specimens described have the abdomen more globular than 
in M. spinipes. Legs i. and ii. are much shorter in proportion, scarcely one-fourth longer than the 
whole body. Femur i. has 3 or 4 spines only in the apical half, femur ii. being entirely devoid of spines- 
The scapus of the vulva is abruptly dilate towards its apex, seen from below.

DREXELIA.

Type of Drevelia, D. directa (Hentz), North America; of Larinia, L. dufouri, E, Simon, Europe *, 
Generic characters drawn from D. directa (Hentz). 
$. Coxa i. without hook. Femur ii. without groove. Patella of palpus with two spines. Maxilla and base 
of femur of palpus with a well-developed cone and ridge; eyes as in female. Q. Carapace not convex 
behind. Posterior row of eyes slightly recurved, laterals subequal. Posterior central eyes almost in 
contact, much smaller than the anterior centrals, which are at least two diameters apart. Central 
* McCook in 1893 (Am. Spid. iii. p. 249) definitely cited L. dufouri as the type of Larinia. Simon did not 
cite L. lineata as the type until 1895. Not having a specimen of L. dufourt before me, it is impossible to say 
whether Drevelia is truly congeneric with Larinia, . The species before me, Epetra tetragnathordes, O. P.-Cambr., 
is, I have little doubt, that which McCook identifies as Epeara directa, Hentz; and it is safer to retain the 
name Drevelia for the present. 
As to Larinia, the species, Cyclosa fissicauda, O. P.-Cambr., and Epeira illicita, O. P.-Cambr., quoted by 
Simon as falling under this genus, directly contradict in many respects the characters given in the diagnosis. 
E. illicita has a coxal hook in the male, and C. fissicauda has the carapace very convex behind, amongst other 
important differences.
