Psyche 
[December 
basal scutum. Color in alcohol: carapace and chelicerae a rich, dark, 
reddish brown; sternum somewhat lighter; legs with femora nearly 
like carapace ; other segments yellowish brown with variations. Ab- 
domen: dorsum and lateral sides a rich dark, reddish brown with 
numerous yellowish dots; muscle impressions yellowish; venter with 
book-lung areas yellowish and region between these streaked with 
brown; behind the genital groove the venter has three brownish 
stripes bordered by four narrow, irregular, yellowish stripes; spin- 
nerets and areas at their bases nearly white; ventral area quite vari- 
able among paratypes. 
Female paratype. Total length nearly 7.6 mm. Carapace nearly 
2.62 mm long; nearly 2.24 mm wide opposite second coxae where it 
is widest; nearly one mm tall shortly behind PME where it is tall- 
est; very finely serrated along ventral margin; with a fairly well 
defined median, thoracic groove. The female selected for description 
follows the features of the male holotype so closely that a detailed 
description is regarded as unnecessary. The epigynum seems to be 
obscurely distinctive (Fig. 15). As usual in this genus, variations 
in the appearance of the epigynum have been noted among the females 
available for comparison (Fig. 16). 
Diagnosis. This species appears to be another member of the 
group represented by Corinna robusta Chickering and Corinna 
bulbosa F. P. -Cambridge. The features of the male palp and the 
obscurely distinctive features of the female epigynum establish it 
as a new species. 
Records. The described female paratype was taken in the same 
locality and at the same time as the male holotype. Both sexes are 
in the collection from the following localities in the Panama Canal 
Zone: Canal Zone Forest Preserve, August, 1939; Gatun, February 
and March, 1958; Barro Colorado Island, Corozal and Balboa, 
May, 1964.

Corinna bulbula F. P.-Cambridge, 1899: 67, figs. 2-2a. The male holo- 
type from Bugaba, Panama is in the British Museum (Natural History). 
Petrunkevitch, 1911: 465; 1925: 75; Roewer, 1954: 595; Bonnet, 1956:

This species has not appeared in my collections from Panama and, 
as far as I have been able to determine, has not been reported since 
the original description was published by the author of the species.
