Sundevall, both widely distributed species in Europe. Later, 
the first species was selected as the type of the genus. 
Simon and Peckham exchanged specimens of the com- 
mon species found in North America and France but 
Peckham did not recognize the genus Peilenes and he 
described most of the American species in the genus 
Habrocestum that he afterwards placed in the genus Pel- 
lenes. In 1900, he redescribed all the American species with 
the third leg longest under the genus Peilenes. A year later, 
F.O.P. Cambridge, who must have been familiar with the 
European species of Peilenes, erected the genus Habronat- 
tus for the species found in Central America that have the 
tarsus of the male palpus not elongate, but more or less 
circular and flattened, with the bulb also circular, with two 
processes, sometimes widely separated, the outer usually 
longer but both following the contour of the cavity ; the pos- 
terior legs are very spinose and the third and fourth tibiae 
have a small dorsal spine at the base. These characters are 
just opposite to the European species of Peilenes. 
The genus Peilenes is described with the quadrangle of 
eyes a little wider behind, small eyes midway between first 
and third rows, anterior legs robust, third pair longest, 
posterior tibiae always lacking a dorsal spine. In the 
European species; the palpus is elongate, bulb long, with the 
embolus arising from the prolateral margin about the middle 
and continuing on margin as a stout, heavy spine to the tip 
of the cavity. There are a few American species that have 
several characters in common with the European. They 
have a similar palpus, and the posterior tibiae have no dorsal 
spine, but the first pair of legs is longer than the third pair 
and the patella is normal. Peilenes peninsulanus Emerton 
and P. longimccnus Emerton belong to this group but neither 
have been found in New England. 
The genus Habronattus has many species in America. 
Eight are known from New England. All have the third leg 
longest and several have modifications on the first and third 
pairs.
