outside the cymbium and both have the median area of the 
scape depressed.

Hentzia squamata (Petrunkevitch) 
W ala squamata Petrunkevitch, 1930, p. 146, figs. ISO- 
134. “several As and ?s, from Mona Island, 24 Febru- 
ary 1914, in the collection of the American Museum of 
Natural History. ” 
The specimens described by Dr. Petrunkevitch all had 
the short vertical mandibles. Six males and six females 
were collected by Beatty in August, 1944. Three of the 
males have the short mandibles and the others have 
mandibles of varying length. When the mandibles are 
long and porrect, the two teeth on the promargin are 
widely separated, one near the base of the fang and the 
other near the base of the joint. The large tooth on the 
retromargin is much nearer the tooth at the distal end, 
than to the second tooth that is almost hidden by the 
scopula of the maxillae. The largest male is 6.0 mm. long 
with the cephalothorax, 2.5 mm. long and 2.2 mm. wide. 
The mandibles are 2.0 mm. long, with the outer margins 
parallel and fringed with long white hairs ; the inner mar- 
gins are touching on the basal quarter and then gradually 
narrow to the width of the fang. On the specimens with 
the long, porrect mandibles, the fang is longer than the 
basal joint with the distal third very slender and curved. 
In all specimens of females, the mandibles are vertical, 
rather thick, with a large bicuspid tooth on the retromar- 
gin. A large female is 6.7 mm. long. 
The species is very close to Hentzia peckhami (Cocker- 
ell), 1893, from Jamaica, (Anoka moneagua Peckham, 
1894). This species is smaller and all of the type speci- 
mens of the Peckham species from Moneague, have short 
mandibles, with no white scales, either on the mandibles 
or on the cephalothorax. The females are also small and 
dark. The epigynes are very similar.
