Tapinesthis inermis Dalmas, Ann. Soc. Ent. France, 1916, 
85: 242. 
A pair of very small spiders was found in the basement 
of the museum of Natural History and figured by Mr. 
Emerton in 1909. Probably because they are very small 
and had but six eyes, he identified them as Orchestina salti- 
tans Banks, the only six-eyed spider found in the north. To- 
day, they are discolored by age and badly broken but it is 
evident that the do not belong to the genus Orchestina but, 
as Comte de Dalmas suggests, they may be Tapinesthis 
inermis, a species found in southern France.

These minute spiders (0:8 mm.) are not often found in 
collections, probably because they are so small and colorless. 
They move very rapidly and because of the large femur of 
the fourth pair of legs, they can jump a great distance com- 
pared to their small size. A pair was found jumping on a 
window sill in Boston and they are not uncommon in southern 
Connecticut. The genus is based on a species from Corsica. 
Three more species are known from the Mediterranean area 
but Orchestina saltitans is the only species reported from 
North America.
