CYNORTA.—ERGINUS. 509 
9. Cynorta conigera, sp.n. (Tab. LIL. fig. 17, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 5 millim. (excl. mand.); protarsus ii. 14 millim. ; 
femora, ii. 10°5, iv. 10 millim. 
General characters similar to those of C. longipes. The third segment of the dorsal scutum bears a pair of 
very stout coniform spines, the bases of the cones themselves bearing spicules. Tarsal segments, i. 6; 
i. 14; iii. 10; iv. 12. 
Colour. Legs slive-brown, annulated with yellow; the annulation being most noticeable on the femora and 
protarsi. Dorsal scutum with a broad reticulated band of greenish yellow, the groove marking the 
junction of the prosoma and opisthosoma being also marked with yellow. 
Hab. Costa Rica (Sarg). 
ERGINUS, Simon. 
Erginus, EK. Simon, Ann. Soc. Ent. Belg. xxii. p. 200 (1879). 
Type £. deville’, Simon (the first species described). Ecuador. 
So far as one can judge from the descriptions of the various species included by 
Simon under Erginus, they are congeneric with the forms now added. The number 
_ of segments in tarsus i. agree, and the third and fourth pairs of legs are distinctly 
stouter than the first and second. The eye-tumulus, seen transversely, in Erginus is 
at least twice, often three times, as long as its breadth ; in Cynorta it is not more than 
one-third longer. 
The species, evidently very numerous in Central and South America, which occur 
in the collection before me may be recognized as follows :— 
Males. 
A. Tarsus iii. with 7 segments. 
a. aeaue iv. with 7 or 8 segments. 
. Tarsus iv. with 7segments. . . . . . 2. . . «© . « . serratifer, sp. n. 
" Tarsus iv. with 8 segments. | | 
a. Patella and tibia iv. (but not the femora) armed marginally 
with specialized denticles. 
a’, Tibia iv. not more than one-fourth longer than patella iv., 
and much dilated. . . . . .. . - . . « . Clavo-tibialis, sp. nu. 
b°. Tibia iv. at least twice as long as patella iv., scarcely 
dilated. 
a‘. Tibia iv. armed on both sides, from the base almost to 
the apex, with 12-16 long, basally coalescent denticles. serrato-tibialis, sp. n. 
b*. Tibia iv. armed, on the inner side only, with a double 
series of short separate denticles . . . . . . . cylindro-tibialis, sp. n. 
b’. Femur iv. (but not the tibia or patella) armed with specialized 
denticles or minute tubercles. 
a’. Femur iv. armed, or studded, with more or less regular 
series of tubercles, but without rows of denticles . . . arcuatus, sp. n.
