constricted basally. Cephalic region black . . . . . nigriceps, O. P.-Cambr.

1. Scoloderus americanus. (Tab. LI. figg. 6, 6a, 0, 2.) 
Carepalxis americana, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 49, t. 4. figg. 8, 
8a-c (2) (nec go)". 
Type, 2, in coll. Godman & Salvin. Total length 4°75 millim. 
Hab. Panama, Bugaba (Champion). 
The cephalic lobe is orange-red-brown, not truncate apically, while the abdomen has 
no central black line beneath. For vulva, see Plate. 
2. Scoloderus nigriceps. (Tab. LI. fig. 7, 2.) 
Carepalzis nigriceps,O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 158, t. 19. figg. 9, 
9a-d(?)’. 
Type, 2, in coll. Godman & Salvin. Total length 2°75 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith'). 
This species is very closely allied to S. americanus, but the cephalic lobe is more 
truncate at the apex and black (instead of orange-red), and the ventral area of the 
abdomen has a central longitudinal black band. ‘The vulva, too, differs considerably 
in form, see Plate. 
8. Scoloderus tuberculiferus. 
Carepalxis tuberculifera, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. 1. p. 48, t. 4. figg. 9, 
9 a,b (?)*; Keyserl. Spinn. Amer., Epeiride, p. 50, t. 2. figg. 40, 40a-c (2)*; McCook, 
Amer. Spid. iii. p. 207, t. 18. figg. 6, 6a-d (@)”. 
Type, 2, in coll. Godman & Salvin. Total length 3:25 millim. 
Hab. Nortu America, Florida? ?,—Guatemata?; Panama, Bugaba (Champion'). 
The type-example is not fully mature, and it is possibly identical with S. americanus, 
though the shoulder-tubercles may furnish a good distinctive character. 
4. Scoloderus gibber. (Tab. LI. figg. 8, 8a, 2.) 
Scoloderus gibber, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. 1. p. 282, t. 36. figg. 4, 
4a-d(9)’. 
Carepalxis americana, O. P.-Cambr. loc. cit. p. 49, t. 4. figg. 7, 7a-c (gb) (nec 2)*; Keyserl. 
Spinn. Amer., Epeiride, p. 51, t. 2. figg. 41, 41 a-d (2), 4Le (g)*. 
Type 2, deuterotype dg, in coll. Godman & Salvin. Total length, 9, 4°75 millim. 
Hab. Mexico, Atoyac (H. H. Smith!: 9); Guatemata®; Panama, Bugaba (Cham- 
piont?: 3).
