chitinous ridge on each side, not meeting on the anterior margin ; 
the posterior lobes on each side converging at the hind margin,

3. Abdomen with an anterior marginal pale band broken in the centre, an 
oblique pale band on each’ side about the middle, a central apical 
elongate diamond-shaped white spot, and a pair of white spots on 
each side close to the apex. For the vulva, see Plate. . . . . . zebraneus, sp. n. 
B. Posterior lobes of vulva widely separate behind. (Abdomen variable in 
pattern, which consists either of a continuous lateral irregular pale 
band, or of four oblique spots, with an indistinct central anterior 
dorsal pale band, followed by a very distinct central pale spot, this 
followed to the spinners by two or three very slender ~-shaped bars, 
but without the elongate pale dash on each side above the spinners. 
Vulva with the usual short transverse rim, and a transverse oval, con- 
tinuous, encircling chitinous rim anteriorly; the posterior lobes on 
each side being widely separate at the hind margin. Epigynal area 
much smaller in proportion.). . 2. . 1. 6 6 ee ee ee (viridipes, Hentz. 
Nors.—I cannot include H. belligerus (Peckh.) in this Table, because it seems to me that the full figure 
given by Peckham represents H. meaicanus. The figure given as the female of H. mexicanus somewhat 
resembles that described here as H. zebrancus. HH. cecatus and H. aztecanus are unknown to me.

Type od, gynetype Q, in coll, Peckham. Total length, ¢ 5, Q 6 millim. 
3g. Carapace black, with a narrow band of rosy-white scales encircling the clypeus and lateral margins. 
Cephalic area thickly clothed with fawn-coloured scales (possibly, in examples not rubbed, continued 
further over the central thoracic stria); a pair of rosy-fawn-coloured bands run from the posterior 
lateral eyes to the posterior margin, these being slightly coalescent in the centre. The legs are orange, 
speckled with brown ; femur i. black, clothed with a thick fringe of more or less speckled clavate hairs ; 
patella and tibia, and the base of protarsus i., with a black band on the inner side ; patella iv. with a pure 
white spot of scales at the base in front, much less distinct in some examples. Abdomen black, with a 
broken, or unbroken, narrow pale encircling marginal line, and a central dorsal anterior band of pale 
scales, often obliterated, followed by three small white ~.- shaped bars or chevrons, sometimes coalescent, 
aud on each side at the apex, just before the spinners, a single elongate white dash-like spot. 
Q. The characteristic markings are given in the Table of species. 
Hab. Mexico, Reynosa and Refugio (Townsend 1), Petapa, Amula, Omilteme, 
Chilpancingo, Teapa (1. H. Smith); Guatemaa (Sarg). 
Numerous males and some females of this species were taken by Mr. Sarg in 
Guatemala, others of both sexes by Mr. H. H. Smith in Mexico. There is no 
reasonable doubt that the males received by us are identical with Peckham’s
