1930] Ant-like Spiders of the Genus Myrmarachne 215 
to near base; fang slightly sinuous with a distinct tooth 
near basal third and beyond that wrinkled within. Palpi 
much shorter than jaws, the tibia little longer than broad. 
Sternum quite narrow, but about as much widened between 
coxse 1 and 2 as behind coxae 2. Legs moderately short, 
tibia 1 with four pairs of spines, one beneath on patella 1. 
Abdomen rather long, plainly constricted above and on 
sides, and with two separate shields. 
Body. — Length 6.5 mm. 
From Victorias and Manapla, Occ. Negros (Pierce). 
A female similar to male except short jaws may be the 
same species.

white hair; jaws red-brown; legs mostly yellow-brown, 
femora often dark, front femur, tibia and metatarsus mostly 
dark brown; abdomen black, a pale band across between 
shields. Cephalothorax cut quite deeply back of eyes, but 
posterior face of head sloping; eyes of second row a little 
nearer to A. S. E. than to third eyes; jaws* fully as long as 
the cephalothorax, heavy, very thick near base (seen from 
side), not constricted on basal part, from above outer edge 
convex, broadest a little beyond middle, each upper edge 
with a carina, above transversely wrinkled, lower inner 
edge with about four rather small teeth on apical part, 
besides the larger and sharp apical tooth, basal part with 
many small teeth, outer edge of fang-groove marked by a 
long row of teeth, plainly visible from side; fang sinuous, 
without tooth, the inner edge before middle somewhat 
wrinkled. Palpi short, tibia moderately short. Legs not 
very long, leg 1 short, tibia with five pairs of spines below. 
Sternum moderately slender, about as wide at coxse 1 as at 
coxse 2. Abdomen moderately short, but with two distinct 
dorsal shields, and slightly constricted between them. 
Body. — Length 4.5-5. 5 mm.
