All the species which we have formerly described under Hahro- 
cestum we now place in Pellenes, M. Simon, who is the author 
of both genera, having assured us that this is their proper place, 
while pulex Hentz, which we had supposed to belong to Saifis, 
is classed by him under Habrocestuni. The species resemble each 
other closely in their form, and often in their patterns. 
To make this paper as complete as possible we include in the 
key such of Mr. Banks' species as he has been able to lend to 
us. Mr. Banks thinks the spider which we describe as P. aiiratiis 
H. is a new species, but in this we disagree with him. He also 
says (Jour. N. Y. Ent. Soc. p. 92, June, 1895) that his species 
Hahrocestum latens, 1892 (together with Ergane taeniata Keys, 
and Hasarius Hoyi P.), is a synonym of Ergane borealis Blkzv. 
H. latens Bks. must not be confused with our Habrocestuni latens 
1896, which we now place under Pellenes. 
The first species described by M. Simon under the genus 
Pellenes is lapponicus, which may therefore be regarded as the 
type. 
So far as we have seen the species described by Koch and 
Keyserling, in Arachniden Australicns, under the name Habro- 
cestum, we think them nearer to Saitis E. S. than to Pellenes or 
Habrocestuni. 
We hope that the key. made from the American species of 
Pellenes in our collection, will lessen the difficulty of identifica- 
tion. Besides the species described in this paper the key includes 
borealis and signatiis Banks, both described in The Canadian 
Entomologist, the former in 1895 and the latter in 1900, conjiinc- 
ins, divaricatus and aztecaniis Banks, Arachn. from Baja Califor- 
nia and other parts of Mexico, Proc. Acad, of Sci. of California, 
3rd Series, Vol. I, No. 7, pp. 285-287, montanus Emerton, Can- 
adian Spiders, Trans. Conn. Acad., IX, July 189^, p. 420, coeca- 
tus H., auratiis H., viripedes H., cristatus H., hirsutus P., pere- 
grinns P., oregonensis P., splendens P., described in our Attidae 
of North America, Wisconsin Acad. Sci. Arts and Letters, Vol. 
VII, latens, niexicaniis, belligerns and paratus P., Attidae of Cen- 
tral America and Mexico, Occ. Pap. Nat. Hist. Soc. of Wiscon- 
sin, Vol. Ill, No. 1, April 1896. We have omitted coronatns H. 
because our specimen is immature. All of these species were 
described under the generic name Habrocestuni.

the first leg serves to distinguish the species.
