2. Enna jullieni, 
Hesydrus jullieni, E. Simon, Ann. Soc. Ent. Belg. xlii. p. 20 (1898) °. 
Type, 9, in coll. E. Simon. Total length 10 millim. 
Hab. Panama (Jullien!)—VENEZUELA, San Esteban !. 
Simon [Hist. Nat. Araign. (2) ii. p. 315] quotes this species as the type of the first 
section of his genus J/esydrus, “tarsi pedum recti haud flexuosi,” and it is therefore 
evidently congeneric with Enna velox. 
I do not know this spider, nor are the characters given in the diagnosis sufficient 
for purposes of comparison

Anterior row of eyes recurved, centrals larger, half a diameter apart, almost in contact with the laterals ; 
posterior centrals less than a diameter apart, further from the laterals. Clypeus variable in form, as high 
as three diameters of an anterior central eye. Both margins of the fang-groove tridentate, the teeth on 
the lower margin equidistant and subequal. Tibi i. and ii. with 2—2—2—2 spines beneath and a pair 
of small apical ones, besides laterals on each side. Protarsi i. and ii. with 2—2—2 spines beneath and a
