NEOSCONA. | 473 
This spider may be the male of W. volucripes ; but since McCook has also described 
a deuterotype male of Keyserling’s species, I am not at all sure that his specimen is 
identical with the male here described. 
[8. Neoscona cooksoni. (Tab. XLIV. figg. 16, 16a, b, 2.) 
Epeira cooksonii, Butl. P. Z. S. 1877, p. 76, t. 13. figg. 2, 2 a-c (2). 
Type, 2, in Mus. Prit. Total length 17 millim. 
Very like WV. oawacensis in general appearance, but legs iii. and iv. are not annulate, and the median ventral 
spot is large and circular, characters which have probably little value. The form of the vulva is, however, 
quite distinct, neither apically geniculate, but very broadly rounded, nor constricted, the base very convex, 
in profile, and dorsally strongly tuberculato-rugulose.

McCook refers his examples from the same locality to V. vertebrata. | 
9. Neoscona orizabensis, sp.n. (Tab. XLIV. figg. 17, 17 a, 5, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 16 millim. 
©. Carapace unicolorous brown, darker marginally. Sternum brown, with a pale central band. Legs orange- 
brown, tibize, protarsi, and tarsi yellow ; femora i. and ii. annulate with black at the base, and iii. and iv. 
at the base and apex ; tibie, protarsi, and tarsi annulate with black at the apex. Abdomen triangular- 
oval, dark olive-brown, paler anteriorly on the dorsal area, having the central band ill-defined, and the 
series of oblique lateral spots, though present, not always conspicuous ; lateral area varying in colour from 
olive-brown to yellow-brown ; ventral area black, with the pair of median white spots large, round, and 
conspicuous, the others less so. Mandibles and base of mouth-parts brown. Femora without series of 
spines beneath. 
Vulva of the same general character as that of the rest of the group, but quite distinct. It is shorter from 
base to apex than in JV. cooksoni, and broader in proportion, though very much curved, in profile, 
presenting a more squat appearance ; the apical spoon is broadly rounded, and the infra-marginal tubercle 
strongly developed. 
Hab. Mexico, Orizaba (H. H. Smith). 
This species is very similar in general appearance to JV. benjamina, but if the form 
of the vulva is any criterion, it is quite distinct.

Q. Very variable in colour. Carapace yellow-brown, with broad marginal brown suffusions. Legs yellow- 
brown; femora with the apical two-thirds (often entirely) black; tibie and protarsi i. and ii. not 
annulate, iii. and iv. annulated with black. Abdomen usually dark brown or black, with the normal 
narrow scalloped pale band and five lateral black spots; lateral area black, its upper margins dentate and 
running up at points into the white upper lateral area; ventral area dull yellow-brown, with the usual 
white spots, but the median pair are the more conspicuous. Femora i.—iv. without spines beneath. 
Vulva similar in general character to that of others of the group, but more lamelliform, seen in profile. As
