ASHTABULA. 
Males. 
a. Abdomen pale yellow, clothed with white hairs, having a central longitudinal 
dorsal, dark, deeply dentated band. Apical spine of palpal bulb very fine 
and short, quite inconspicuous. ‘Tibial spine of palpus geniculate. Basal 
segment of mandible much excavate below the base of the fang, with a very 
long upper and under tooth, and a third smaller one. The fang itself with 
a large tooth or enlargement on the upperside near the basal half. Cephalic 
quadrangle occupying half the carapace . . . soe . . . dentata, sp. n. 
6. Abdomen black, the dorsal area entirely clothed with green iridescent scales 
and margined with a narrow band of white. Apical spine of palpal bulb 
stout, conspicuous, and slightly sinuous. Tibial spur of palpus slightly 
curved, not geniculate. Basal segment of mandible with a single short 
stout tooth on the upper and lower margin of the fang-groove. Cephalic 
quadrangle of eyes occupying less than half the carapace . . . . . . migricans, sp. n. 
Notr.—The female of A. dentata is unknown to me and that of A. nigricans is not adult; I cannot, 
therefore, give figures of the vulva of either. 
1. Ashtabula dentata, sp.n. (Tab. XXIII. figg. 1, 1 a-e, ¢.) 
Type, d, in coll. Godman & Salvin. Total length 4 millim. 
For a description of the specific characters, see the Table. 
Hab. GUATEMALA (Sarg). 
This species, in general appearance, resembles A. zonura, Peckh., but the tibial spur of 
the palpus is differently formed, and the mandible also is evidently very dissimilar, 
Peckham not mentioning the long teeth on the basal segment, nor the enlargement 
above of the fang in the basal half. 
2. Ashtabula nigricans, sp.n. (Tab. XXIII. figg. 2, 2a-¢, 3; 3, 2.) 
Type, d, in coll. Godman & Salvin. Total length, ¢ 4°75, 2 juv. 5°5 millim. 
Coloration similar in both sexes. Carapace and abdomen black, the former clothed dorsally with a large area 
of green and copper iridescent scales, embracing the cephalic area, and extending over halfway to the 
posterior margin. Abdomen clothed over the entire dorsal area with iridescent scales, cinctured marginally 
with a narrow white band; ventral area black. Legs black-brown; protarsi and tarsi yellow; tibia iil. 
and iy. also yellow, with lateral brown bands. Femur of palpus brown; patella, tibia, and tarsus yellow. 
gd. Leg i. much incrassate ; tibia two and a half times longer than broad, with three pairs of short stout spines 
on each side in the apical third; protarsus i. as long as the tibia, with 2—1 stout spines beneath ; tarsus more 
than half as long as the tibia. 
9. Leg i. incrassate ; tibia one and a half times longer than broad, with three pairs of short spines in the 
apical third. In both sexes the anterior margin of the femur and the underside of the patella and tibia 
are thickly fringed with stout hairs. Tibia iv. with one or two spines on each side and two at the apex 
beneath ; protarsus iv. with one or two spines at the sides and four at the apex beneath. Maxille dilate 
at the apex. Coxe i. almost a diameter apart. Mandibles short and stout, with a single tooth above 
and below.
