Norz.—One must not attach too much importance to the number of tarsal segments on leg ii., because 
these are often very difficult to distinguish. The number of segments in legs iii. andiv. is by no means constant 
in both sexes of a species; and possibly, even in the same sex, individuals may occur in which the number is 
not constant in the case of these legs. This, however, does not nullify the value of these characters: we have 
merely to recognize individual variation from characters which are otherwise in the majority of examples 
constant. So far as the material at hand enables me to judge, the segments of tarsus i. are constant in both 
sexes, 
1. Cynorta albipunctata, sp. n. (Tab. LII. figg. 9, 9 a, b, 3.) 
Type 3, gynetype 2, in coll. Godman & Salvin. Total length, g 5, 2 4 millim. (excl. mand.); femur iv., 
o, 95 millim. 
g. Legs, unlike those of Hrginus, subsimilar, the third and fourth pairs not markedly larger, nor are the 
femora of the fourth pair much specialized. The spines on the tergal third segment are very small, mere 
tubercles, often obsolete. ‘Tarsal segments, i. 6, 1-3 somewhat dilate; ii. 11; iii. 7 ; iv. 8. Legs 
covered with minute tubercles; coxaiv. with a blunt apical spur; trochanter iv. without spurs; femur iy. 
almost straight, slender, with two series of more conspicuous, but still very small, tubercles beneath ; 
tibia iv. with a similar double series, and protarsus iv. with a single series, of similar tubercles beneath. 
EKye-tumulus one-third longer, transversely, than broad. 
?. Similar to the 3, except that the fourth pair of legs is similar to the rest and the segments of tarsus i. 
are not dilate. 
Colour. Body and legs very pale olive-green, the latter not annulate, their apices and the underside more or 
less suffused with black. Behind the eye-tumulus, and embracing it, lies a triangular black blotch 
outlined behind and laterally with a fine yellow line; the first, second, and third segments of the dorsal 
scutum are outlined marginally, the third also posteriorly, with fine yellow lines, enclosing in a scalloped 
pattern three black blotches on each side. Between these and the lateral margins are some irregular 
filigree yellow lines ; the fourth and fifth segments, as well as the free segments, are studded each with 
a transverse row of yellow dots. There is also a central series of a few dots, besides a sublateral dot on 
each, on segments 1, 2, and 3 of the dorsal scutum. A short yellow line runs also from the apex of the 
lateral scallop of segment 3 to the margin. 
Hab. Costa Rica (Sarg). 
2. Cynorta bipunctata, sp.n. (Tab. LII. figg. 10, 10a, 3 .) 
Type ¢,gynetype Q, in coll. Godman & Salvin. Total length, ¢ & 9, 5 millim. (excl. mand.); protarsus ii. 
6°5 millim.; femur ii. 6 millim. 
General characters as in the allied species, except that the legs are stouter and the eyes wider apart, the eye- 
tumulus being about twice as long as broad. Segment 3 of the dorsal scutum with a pair of short, stout 
coniform cusps. Tarsal segments, i. 6, 1-3 dilate; ii. 13; iii, 7 3 iv. 8. Femur iy. plain, without 
denticles, and with only very minute spicules or cusps. Body entirely smooth. Coxa and trochanter iv 
with slight apical spurs. °
