Linn. Bord. xliv. p. 828 (1892) *. 
Type, 2, in Brit. Mus., ex coll. Keyserling. 
Hab. Mexico, Yucatan 2. 
8. Ischnothele zebrina. 
Thelechoris zebrina, E. Simon, Act. Soc. Linn. Bord, xliv. p. 329 (¢?)°. 
Hab. Nicaracva, Polvon (Packard *). 
There is no doubt whatever that the New World forms referred by authors to 
Karsch’s genus Thelechoris belong to Ausserer’s genus Ischnothele. 
4. Ischnothele guianensis. (Tab. II. fig. 9, ¢.) 
Mygale guianensis, Walck. Hist. Nat. Ins. Apt. p. 23 (g) (1887) . 
¢ & 2. Carapace unicolorous mahogany-brown, the margins darker. Legs pale yellow beneath ; coxe pale 
yellow ; femora darker at the apex above; tibie and protarsi pale yellow, each with a basal and apical 
annule of dark brown; tarsi yellow. Sternum pale yellow. Abdomen dark purple-brown, with a double 
central dorsal series of three minute oblique pale dots. Basal joint of the spinners pale yellow, its apex 
dusky beneath ; second joint brown ; terminal joint brown at the base, pale yellow towards the apex. 
g. General characters as in other species of the genus. The specific character is furnished by tibia i., whose 
apical spur is narrow, elongate, and armed with four stout spines at the apex, while the protarsus bears 
in the centre beneath a small, stout, sharp, coniform spur, its apex directed inwards. Tarsus i. nume- 
rously spinose on the inner side beneath, 3 or 4 spines only on the outer side. 
Hab. Costa Rica (Rogers).—GutIana t. 
Five females and one male of this small species were taken by Mr. Rogers in Costa 
Rica, but the exact locality is doubtful. J. guianensis is very similar in general 
appearance to J. digitata, but is much smaller, and differs in some essential points of 
structure in the male sex. I have identified this species from males and females thus 
named by M. Simon in the British Museum. 
EUAGRUS. 
Euagrus, Ausserer, Verh. zool.-bot. Ges. Wien, xxv. p. 160 (1875). 
Type Huagrus meaxicanus, Auss. 
I have not seen the type of this genus, and my knowledge of it is based on a 
specimen ( @ ) identified by M. Simon, and kindly submitted for examination. So far 
as one can judge, there seems no reasonable doubt that this specimen is generically 
and specifically identical with Ausserer’s form, though a glance at the type would be 
more satisfactory. 
Tarsal claws 3. Spinners set wide apart at the base. Terminal joint of the posterior spinners scarcely longer 
than the second, not flexuose or segmentate, scarcely attenuate.
