MAZAX.—MYRMECOTYPUS. 83 
cephalic area. Abdomen produced in front into a cylindrical, rugulose pedicle, scutulate at the base, with 
or without a pair of spines. Both margins of the fang-groove with two minute teeth. Tibie and protarsi 
i, and ii. with pairs of spines beneath, varying in number and length. Femur of the palpus(Q) with 
four or five stout spines beneath, on the lower margin. 
To this genus doubtless belongs Apochinomma acanthaspis, Sim., from the Amazons. 
The two species now recorded from Central America may be recognized as 
follows :— 
a. Abdomen and abdominal scutum clothed with long hairs, the latter 
bearing in front a pair of stout spines articulated to a basal cusp. 
Abdomen globular, with an oblique band of white on each side about 
the middle, and an indistinct transverse dorsal bar towards the apex. 
Tibiz i. and ii. with 2—2—2 pairs of spines beneath . . . . . spinosa, O. P.-Cambr. 
6. Abdomen and abdominal scutum smooth, clothed with very fine short 
hairs only, without spines, but with two very fine bristles only in front 4 
of the scutum. Abdomen elongate-oval, with a narrow white cincture 
before the middle of the dorsal and lateral areas, broken where it 
meets the posterior margin of the scutum. Tibi i. and i. with 
2—2—2—2—2 spines and 2—2—2 respectively. . . . . . . . plana, sp. n. 
1. Mazax spinosa.

2a-e(2)’. 
Type, 9, in coll. Godman & Salvin. Total length 5 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatremara (Sarg). 
2. Mazax plana, sp.n. (Tab. VI. fig. 11, ¢.) 
Type, 2, in coll. Godman & Salvin. Total length 6-5 millim. 
@. Carapace and mandibles mahogany-brown, the latter striped with darker brown; sternum paler. Legs 
pale orange-yellow, the first pair paler, striped and mottled with brown. Inner side of the femora of all 
four pairs, and of the tibiz of iii. and iv., and the outer side of the femora towards the base, suffused with 
brown. Protarsi of all four pairs suffused about the middle and on the underside with brown. Abdomen 
deep purple-brown, with a cincture of white just before the middle, interrupted in the middle on the 
dorsal line. On each side of the genital rima is a small piriform spot of white hairs. A ventral area 
with a white sinuous longitudinal blotch on each side and a finer sinuous line of pale spots extending 
from the piriform spot almost to the spinners on each side. 
Structure similar in general respects to that of WM. spinosa, but the abdominal scutum is hemispherical, smooth, 
and shining, without any spines, but with only a pair of very fine bristles. The abdomen itself is 
elongate-oval. There is no external structure belonging to the genital organs which can be used for 
purposes of specific comparison in either of these species.
