11. Micrathena parallela, (Tab. L. figg. 13, 134, b, ¢ .) 
Acrosoma parallelum, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 60, t. 8. figg. 15, 
15 a-d (g¢)*; Keyserl. Spinn. Amer., Epeiride, p. 16, t. 1. figg. 12, 12a(¢)’. 
Type, ¢, in coll. Godman & Salvin. Total length 5 millim. 
Carapace brown-orange, broadly margined with black-brown, oval-elongate, with a central punctiform fovea 
and three lateral fovese. Abdomen parallel-sided, elongate, compressed, truncate at each end, dull yellow- 
white, broadly margined along the anterior two-thirds with dull metallic blue-black; sides and ventral 
area closely punctured. Femora i. and ii. without anterior dorsal spines; tibie i. and ii. with a double 
series of short stout spines beneath. Coxa i. with a stout, curved, apical hook; femur ii. with a groove. 
Palpal bulb elongate, produced to a blunt dark point ; embolus concealed; tarsal hook with its anterior 
margin finely serrate in the apical half, see Plate.

12. Micrathena uncata, sp. n. (Tab. L. figg. 14, 14 ac, 3.) 
Type, gS, in coll. Godman & Salvin. Total length 6 millim. 
General structure as in MW. parallela. Tibiw i. and ii. with several long spines beneath, but without the 
double row of short spines characteristic of the last-mentioned species. Femora i. and ii. with a more 
or less scattered series of long spines extending down its anterior dorsal side from near the base to the 
apex, and also a single series of ten or eleven short stout spines beneath. 
Palpal bulb bluntly rounded apically. Embolus just visible, lying within the concave sheath-like conductor 
and almost beneath a stout, slightly curved, pointed, black uncus. Tarsal hook not serrate on its anterior 
margin,

Acrosoma reduvianum, E. Simon, Hist. Nat. Araign. édit. 2, u. p. 854, fig. 914 (2) *. 
Type, 2, in Mus. Munich; deuterotype, ¢, in coll. Godman & Salvin. Total length, 2 5°5, ¢ 3 millim. 
gd. Carapace dull orange-brown, the legs paler. Abdomen brown, apically dull black, with very distinct 
white cretaceous spots: anteriorly there is a horseshoe-shaped spot, followed by a long spot on each 
side, and a small central one, then a transverse elongate spot followed by a small central one, and on 
each side at the commencement of the black apical blotch there is another spot, 
Femora i. and ii. with long dorsal spines, but without series of short spines beneath. Patella and tibie i. 
and ii. with some stout clasping-spines, patellee with two on the inner side near the apex; tibie with 
numerous stout spines irregularly situated beneath. Coxa i. with a hook and femur il. with a groove. 
Palpal bulb bluntly rounded at the apex. Conductor sinuous, apically produced into a thin concave 
pattledore-like sclerite. Tarsal hook very similar to that of the allied species, not serrate on its inner 
margin. 
Q. Carapace not very deeply grooved transversely behind the cephalic region ; the margins set with minute 
setigerous tubercles ; central fovea well-marked. Sternum not markedly convex in the middle, scarcely 
longer than broad. Abdomen with a pair of short anterior-marginal conical angles, not spines nor 
cusps; no lateral marginal cusps; a pair of short sharp divergent spines directed obliquely upwards and 
backwards occupy the posterior margin, one at each angle, while beneath these and behind lies a shorter, 
stout (variable in length), sharp, conical cusp. Tho dorsal area is not punctured, but the posterior and 
lateral areas are pitted on the ridges of the folds of the integument with more or less regular rows of 
minute punctures. 
The vulval scape is similar to that of the allied species in general character, but differs in detail, see Plate, 
Colour: abdomen varying in colour from yellow-white to sooty-black or metallic blue-brown, the light- 
coloured forms being often mottled or blotched.
