ERGINUS. 563 
Colour, Body reddish-ochre-brown, the legs paler. A broad band of filigree pattern in yellow runs round 
the margins of the dorsal scutum, but the disc is almost devoid of yellow spots. 
Hab. GuaremAna, Quirigua (Sarg). 
5. Erginus arcuatus, sp.n. (Tab. LII. figg. 22, 22 a-c, ¢ .) 
Type, ¢, in coll. Godman & Salvin. Total length 4 millim. (excl. mand.) ; femur iv. 4 millim. 
d. General characters similar to those of H. pectinigerus, but more nearly allied to E. crassescens ; 
trochanter iii. and coxa and trochanter iv. without spurs, and femur iv. not dilate towards the apex, 
but basally dilate and attenuate towards the tip. ‘Tarsal segments, i. 6; ii. 13; iii. 7; iv. 8. 
Femur iv. basally dilate, gradually attenuate towards the apex, strongly curved, sinuous; without a 
series of long denticles, but with irregular rows of tubercles. 
Colour. Body rich ochre-brown, the legs ochre-yellow. Prosoma and opisthosoma divided dorsally by a fine 
yellow line, with a spot at each lateral terminal. Dorsal scutum with a broken central line, and the 
third segment outlined posteriorly with a yellow bar. 
Hab. Guatemata, Cubilguitz (Sarg). 
6. Erginus sinuosus, sp. n. (Tab. LII. figg. 23, 234, 3.) 
Type ¢, gynetype 2, in coll. Godman & Salvin. Total length, ¢ & @, 5 millim. (excl. mand.). 
3. General characters similar to those of E. pectinigerus. The spines on the tergal third segment are 
moderately long, but not so long as in FE. erectispinus. Tarsal segments, i. 6; ii. 11-12; iii. 8; iv. 8. 
Specific characters generally similar to those of the last-named species, except those of femuriv. The 
latter with an inferior internal sinuous series of 16 denticles, about as long as the width of the segment, 
those of the whole series being subequal in length, basally coalescent, the apical 3 or 4, however, some- 
times separate, extending from the base to near the apex of the segment; with also an external series 
of 14-15 short dentiform tubercles, extending from the base to the apical third of the segment, and a 
basal dorsal series of 5 or more low separate tubercles. 
Colour. Body olive-ochre-brown, the legs paler. Prosoma margined laterally, but not posteriorly, with 
yellow. Dorsal scutum with a few marginal yellow lines and some central dots; the posterior margin 
of the first segment indicated by a fine line on each side, broken in the middle, the second segment by a 
few yellow dots on each side, the third by a fine curved line on each side ; the posterior margins of the 
fourth and fifth barely indicated in yellow. 
Q. Similar to the ¢ in structure and colour, except that femur iv. is simple, without denticles. 
Hab. Guatemata, Tamahu (Sarg). 
7. Erginus simplicipes, sp.n. (Tab. LIII. figg. 1, 1 a-c, 3.) 
Type d, gynetype 2, in coll. Godman & Salvin. Total length, ¢ & 2, 5 millim. (excl. mand.). 
g. General characters similar to those of H. pectinigerus. The spines on the tergal third are moderately 
long, but not so long as in #&. erectispinus. Tarsal segments, i. 6; ii. 13; ili. 7; iv. 8. Specific 
characters generally similar to those of the last-named species, except those furnished by femora iv. 
The latter uniformly cylindrical throughout, with an internal inferior slightly sinuous series of 10-11 
separate denticles, not basally coalescent, subequal in length, about as long as the diameter of the 
segment, extending along the basal two-thirds ; also an inferior apical series of 4 denticles, being 
the apical tubercles of a series lying adjacent to the above-mentioned series, and a dorsal series of 
numerous tubercles, besides two other rows of tubercles. 
Colour. Body dull olive-green, the posterior legs paler. Prosoma limited posteriorly by a fine semicircular 
yellow line. First segment of dorsal scutum having on its disc a short céntral line and a dot on each 
side, its posterior margin outlined laterally with yellow. Second segment with a short central line and 
4 of 2
