564 OPILIONES. 
a dot on each side on its disc, but not posteriorly margined. Third segment with a central line between 
the cusps, margined posteriorly with yellow. 
9. Similar in structure and colour to the dg, but with femur iv. simple, neither dilate nor tuberculate. 
Hab. Guatemata, Chicoyoito, Cubilguitz (Sarg). 
8. Erginus subserialis, sp.n. (Tab. LIII. figg. 2, 2a, b, 3.) 
Type, d, in coll. Godman & Salvin. Total length 7 millim. (excl. mand.); femur iv. 4:25 millim. 
General characters as in E. pectinigerus and E. sinuosus. Eye-tumulus without tubercles, Spines on the 
third tergal segment represented by a pair of warts. Tarsal segments, i. 6, the three basals not dilate ; 
ii. 9; iii. 7; iv. 8. Basal segment of mandible with few external marginal warts; apical segment 
moderately well-developed. Femur of palpus with a dorsal series of small denticles in the basal 
two-thirds, and an inferior marginal series as usual in the genus. Segment 5 of the dorsal scutum with 
a median posterior marginal row of three, the four free segments with median rows of four to six 
tubercles. Femur iv. short, basally dilate, slightly curved outwards at the base, with three dorsal, as 
well as an external, series of warts, and an inferior slightly sinuous series of fourteen short (none as long 
as the diameter of the segment) partially coalescent denticles extending from near the base almost to the 
apex ; with also a short inferior internal series of five, one short and four longer, denticles, forming a 
short group at the base lying on the inner side of the longer series. Tibia iv. bearing six longitudinal 
series of warts, and leg iii. also covered with small warts; femur ili. with an inferior series of short 
denticles. 
Colour. Body ochre-olive-brown, the legs paler. Prosoma and dorsal scutum margined with a filigreed band 
in yellow. Disc of the latter dotted with yellow: third, fourth, and fifth segments margined posteriorly 
with yellow. The four free segments also picked out with yellow, transversely. 
Hab. Guatemata, Tecpan (Stod/).

9. Erginus cristatus, sp.n. (Tab. LIII. figg. 3, 3a, 6, 3.) 
Type, 3d, in coll. Godman & Salvin. Total length 6 millim. (excl. mand.); femur iv. 4°75 millim. 
3. Similar in general character to EH. pectinigerus. The spines on the tergal third segment are almost 
obsolete, appearing as small tubercles. Tarsal segments, i. 6; ii. 11; iil. 7; and iv. 8. Femur iv. 
with series of denticles in the apical half only, where there are two rows of 10 or 11 tuberculiform 
coalescent denticles on each side beneath, and a dorsal series of 4-6 separate denticles about the middle 
of the segment. ‘Tibia iv. with a row of 7 separate, short, tuberculiform denticles beneath, besides other 
rows of smaller tubercles. Femur iii. without denticles. Mandibles similar to those of E. erectispinus. 
Eye-tumulus quite smooth, without tubercles. 
Colour. Body pale olive-green ; legs ochre-yellow, broadly banded with pale olive-green. The various grooves 
marking the limits of the prosoma and opisthosomatic segments of the dorsal scutum are indicated 
symmetrically on each side by yellow spots or short lines,

10. Erginus crassescens, sp.n. (Tab. LIII. figg. 4, 4a, ¢.) 
Type, d, in coll. Godman & Salvin. Total length 5 millim. (excl. mand.) ; femur iv. 4 millim. 
g. General characters similar to those of H. pectinigerus, and specific ones approaching those of E. simplicipes. 
Tarsal segments, i. 6; il. 12 or 13; iii. 7; iv. 9. Femur iv. gradually dilate towards the apex, 
especially on the inner inferior side, claviform (thus differing from both E. simplicipes and E. clavipes), 
having an internal inferior sinuous series of 10 long separate denticles, not basally coalescent, extending 
from near the base almost to the apex, 4 and 5 being the longest, scarcely as long as the diameter of the 
segment ; with an inferior apical series of 5 denticles, being the apical tubercles of a row lying adjacent
