CYRENE. 237 
23. Cyrene laticava, sp.n. (Tab. XX. figg. 3, 3a, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 7-5 millim. 
Hab. Guatemaua (Sarg). 
Very similar to others of the group including C. prominens, C. bicuspidata, &c., 
differing from all, except C. bicuspidata and C. bicavata, in having a black patch on the 
inner anterior basal part of femora i. and ii., and a black spot on the inner side of 
patelle i. and ii. Too great reliance, however, must not be placed on these slight 
differences in coloration, for much more material for comparison is required before 
one can judge of their real value for purposes of identification. The vulva is quite 
distinct in form: the posterior margin is deeply notched in the middle, the whole 
posterior half forming a broad transverse oval concavity, with a rounded protuberance 
in the middle of its anterior margin; in front of this lies an oval-oblong chitinous area 
clothed with hairs. 
24, Cyrene simplicicava, sp.n. (Tab. XX. figg. 4, 4a, b, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 8-5 millim. 
Hab. Mexico, Acapulco (H. H. Smith). 
This species is very like C. /atccava in general appearance, including the black patch 
on the inner anterior basal portion of femora i. and ii. The abdominal pattern, how- 
ever, is much more clearly defined, the central pale dorsal band being broader, more 
conspicuous, and suddenly enlarged just behind the middle, and then again contracted, 
forming four or five chevrons. The vulva is quite distinct in form, having no anterior 
prominence and not being so deeply incised or emarginate behind. 
25. Cyrene pallida, sp.n. (Tab. XX. fige. 5, 5a, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 10 millim. 
Hab. Guatemara (Sarq). 
This large species belongs to the C. prominens-group, but the dorsal pale band is 
much broader and dilate behind, forming a large pale triangular spot. The abdomen 
is, however, denuded of hairs, so that it is difficult to say whether the pale markings 
would not be obscured in its normal condition. The carapace has a marginal band of 
white hairs and a central posterior white band, and the cephalic area is sparsely clothed 
with white hairs. The vulva is formed on the same plan as that of C. albosignata and 
C. elegans, consisting of a slightly emarginate sinuous posterior margin, with a pair 
of dark blotches in front marking the convolutions of the oviduct, while in front of 
these lie, instead of a large concavity, a pair of widely separated chitinous semilunar 
edges marking the entrances to a pair of orifices.
