F.O.P. -Cambridge probably bad this species which 
he identified in the Biol. Centr. America, as Habronattus 
viridipes, following the Pecldiams identification of 1885 
and 1900, of the Hentz species. Later in 1909, the 
Peckhams corrected their identification of viridipes 
Hentz and named the species found in Texas, fallax. 
A year latter, in 1910, Petrnnkevitch in his catalogue, 
erroneously considered the Mexican species the same as 
fallax from Texas. 
Habronattus viridipes (Hentz) has a heavy fringe of 
white hairs on the first pair of legs and the third pa- 
tella is modified. Habronattus fallax (Peckliam) has no 
fringe on the first pair of legs, the third patella not en- 
larged and the legs conspicuously ringed with white 
and black hairs. Habronattus cambridgei has no fringe 
on the first pair of legs, but the femur is slightly flattened 
and the area is covered with white scales ; the cephalotho- 
rax is more slender than in the other two species and has 
a brush of white hairs above the first row of eye s and no 
white scales on the clypeus. 
The female of Habronattus cambridgei is strikingly 
unlike the other species. Both viridipes and fallax have 
distinct abdominal patterns as in the males, while in 
cambridgei the abdomen has no dorsal pattern. The 
epigvnum is typical of others of the genus.
