20 ARANEIDEA. 
Hab. Mexico, Ciudad and Ventanas? in Durango (Forrer: ¢); Panama (coll. 
Simon: 3g); CentraL America (Seemann 1). 
Besides the original type described by White, two adult males were captured by 
Mr. Forrer in Mexico, and one adult male exists in the collection of M. HE. Simon. 
The above measurements were taken from this last-mentioned specimen. No temales 
have yet been found apparently, and therefore no notes as to the habits of this fine 
species have been made. 
I am unable to recognize the generic distinction between Brachypelma, Simon, and 
Eurypelma, Koch, based on the fact of the apical half of protarsus iv. being scopulate 
and the legs clothed with long hairs. Eurypelma vagans presents these characters, 
and of the numerous species before me which I assign to Eurypelma there are 
intermediates in the case of both of them. 
I believe, however, that the characters noted by M. Simon indicate a number of 
species which perhaps make up a natural and convenient group in the genus. 
2. HKurypelma smithi, sp.n. (Tab. I. fig. 4, 2.) 
Type, 2, in coll. Godman & Salvin. 
Q. Total length 60 millim. Carap., length 21, breadth 20; ceph. area 13°5; ocular tumulus 2°5 x 2; mand. 9°5. 
Legs: i. 73°5; ii. 70; iii. 68; iv. 81—i. tib.+pat. 23, tib. 13°5, prot. 12°5—iv. tib.+ pat. 23, tib. 15, 
prot. 19 millim. Tarsal claws not toothed. 
@. Carapace pale orange, cephalic area suffused with brown ; anterior margin fringed with orange-rose hairs. 
Mandibles dark grey, clothed with long rose-coloured hairs. Abdomen clothed with dark velvety-brown 
pubescence, intersprinkled with long dull orange hairs. Sternum and coxe of legs deep brown. Labium 
and cox of pedipalps paler. Femora of legs deep brown, fringed with long hairs beneath. Patelle dull 
orange, clothed with long hairs. Tibi black in their basal half, dull orange in their apical half, clothed 
entirely with dull orange hairs. Protarsi almost entirely black, their apex dull orange, clothed throughout 
with long orange-grey hairs. Pedipalps of the same colour as the legs. 
Differs little from the typical forms of the genus Zurypelma. Carapace almost as long as broad and flat. 
Fovea small, transverse, recurved. Tibia+ patella i. as long as tibia+patella iv. Protarsus iv. clothed 
beneath in the apical half with a thick scopula. 
Hab. Mexico, Dos Arroyos in Guerrero 1000 feet (H. H. Smith). 
At first sight, this interesting form might be taken for E. emilia (White), but in the 
three males of the latter before me the patella of the legs is entirely dark brown, while 
the hairs on the tibie and protarsi are of a much more fiery orange-red. Although so 
strikingly alike in general appearance, I have not the slightest hesitation in describing 
the single female from Dos Arroyos asa new species. The tarsal claws in the males above 
referred to E. emilia are toothed, while those of the present form are not. Mr. Smith 
says :—“ The red-legged species makes deep holes in banks, with a silken lining and 
slight exterior web.” It appears also highly possible that this form is the female of 
Eurypelma mesomelas, O. P.-Cambr., but the entire absence of the thick tufted hair so 
noticeable on the carapace, femora, and other joints of the legs in this latter species 
prevents me from recognizing them as identical. N
