340 ARANEIDEA. 
1. Peucetia longipalpis, sp.n. (Tab. XXXII. fig. 11, ¢ .) 
Type, d,in coll. Godman & Salvin. Total length 10 millim. 
The coloration is much the same as in P. bibranchiata. Carapace and legs orange, sternum and abdomen 
green. Palpus of male quite distinct in structure from that of the next species: tibia four times as long 
as broad; the lateral lamelliform spine lying on the outer side of the bulb, near the base, is unibranchiate, 
broad, flat and dilate at the base, suddenly bent upward and narrowing, directed forward, its aculeate apex 
directed slightly downward. The long central process is shorter than it is in P. bibranchiata. 
- Hab. Mexico, Amula (H. H. Sinith). 
Iam unable to identify any female satisfactorily as belonging to the males here 
described. 
2. Peucetia bibranchiata, sp. n. (Tab. XXXII. figg. 12, 12a, 3 ; 18,13 a-<, 2.) 
Peucetia thalassina, Keyserling, Verh. zool.-bot. Ges. Wien, xxvi. p. 702, t. 2. figg. 67, 68 (¢) 
(nec 2) (1877) ?. | 
Type ¢,gynetype 2, in coll. Godman & Salvin. Total length, g 10, 2 15 millim. 
Colour bright green, legs and carapace orange. In some examples of the female the orange and green are 
more or less suffused with a rosy tint, and the abdomen has a double dorsal series of elongate pink lines 
down the centre. 
Palpus of male very characteristic: tibia not more than three times as long as broad ; the lateral lamelliform 
spine at the base of the bulb on the outer side is bibranchiate, very slender throughout, the inner branch 
stouter, the outer longer, more slender, filiform (really a continuation of the inner folded back), curving 
suddenly downward and then straight forward, but with a slightly sinuous curve. 
‘Vulva of the female very variable in form, consisting of a deep semicircular cavity anteriorly, a pair of 
variously formed deep orifices (one on each side) posteriorly, with a flat blunt spur, very variable in length, 
directed forward into the cavity. [Some specimens have no trace of these spurs, and they may belong 
to a different species. | 
_ Hab. Mexico, Chilpancingo, Dos Caminos, Venta de Zopilote, Tierra Colorada, 
Amula, Atoyac, Jalapa (H. H. Smith), Oaxaca!; Guatemata (Sarg); Costa Rica, San 
José (Tristan). 
The type (¢) and gynetype (2) of the species identified by Keyserling as 
P. thalassina (Koch), from Oaxaca, are before me. Our males agree with the 
Mexican specimen of that sex, but the female named by this author appears to be not 
fully mature. It is not at all likely that the Central-American examples belong to 
Koch’s species, the type (2) of which was from San Domingo, West Indies, and I 
therefore give them a new name, more especially since it is impossible to state 
positively that our males are the true sexual complement of the female type. 
8. Peucetia quadrilineata. 
Peucetia quadrilineata, E. Simon, Bull. Soc. Zool. Fr. xvi. p. 111 (1891)*. 
Type, Q,in coll. E. Simon. Total length 12 millim. . 
Hab. Costa Rica}. 
There are several adult females of a Peucetia from Costa Rica in our collection, but 
I am unable to identify any of them with certainty as Simon’s species.
