No. 1.] ATTID^ OF CENTRAL AMERICA. 69 



wide curved band of white hairs across the anterior end, fol- 

 lowed by a similar band of brilliant red hairs, back of which is 

 a second band of white, which is extended down the middle 

 line to the spinnerets by a narrow white herring-bone stripe. 

 On the sides of this stripe are two somewhat triangular regions 

 covered with black hairs, with which a few red hairs are mixed, 

 on which are two pairs of white spots. The outer sides of these 

 black regions are scalloped with white. In one of our females 

 the anterior white band sends a projection backward in the 

 middle line, while the second white band widens in the mid- 

 dle of the dorsum and has, just at the beginning of the her- 

 ring-bone stripe, a small central spot of mingled black and red 

 hairs. The clypeus is covered with long white hairs, the tips 

 of which meet in the middle line. Some short white hairs 

 grow down over the falces. The palpus is yellow, with scanty 

 white hairs. All the legs have the femoral joints pale yellow. 

 The first and second pairs have the patella and tibia dark with 

 a light streak above and below. The third and fourth pairs 

 are barred with yellow and dark brown. 



The male is darker colored than the female. The cepha- 

 lothorax is black with wide white bands on the sides, a central 

 white spot on the front part of the head and another behind 

 the dorsal eyes. Tlie abdomen, under alcohol, is like that of the 

 female, but when dry, in two of our three specimens it is cov- 

 ered with red hairs excepting the anterior white band, some 

 small white chevrons in the middle line of the posterior part, 

 the four white spots and the white scallops on the posterior 

 sides. In the third specimen the red hairs extend entirely over 

 the second white band, but it is otherwise like the female. 

 The palpus is covered with white hairs as far as the tarsus, 

 which is black. The first and second pairs of legs are dark 

 with some scanty white hairs growing on the under side of the 

 femoral joints. The third and fourth pairs are barred with 

 lighter and darker brown. 



In both sexes the venter usually, but not always, shows a 

 rectangular pale region on which is a central dark streak, and 

 a dark band, sometimes broken into spots, on each side.
