246 ARANEIDEA. 
central short anterior wedge-shaped pale band, its apex extending just beyond the middle; lower lateral 
area brown; ventral area pale, with three longitudinal brown bars. Clypeus clothed with white hairs. 
Leg i. without the tibial clavate spines noticeable in H. mexicanus. Palpus similar in general character to 
that of others of the genus; the bulb is bilobate, and two stout spines (the inner one being the stoutest) 
spring from the outer lower part, curving round, the outer one terminating in a filiform point, which 
lies in the usual groove beneath the apex of the tarsal sheath ; the tibial spur is stout, slightly sinuous, 
bluntly pointed at the apex. 
Hab. Gtatemata (Sarg). 
A single male only of this very small species was sent by Mr. Sarg.

Hab. Mexico, Tepic!. 
The figures of the palpal bulb and of the dorsal spur are not snfficiently detailed to 
enable one to compare the characters of //. aztecanus with those of the species in our 
collection. The two large black spots on the shoulders of the abdomen, and the 
apical half being black with a central triangular white spot, should, however, prove a 
good clue towards its identity. 
COLONUS, gen. nov. 
Type C. puerperus (Hentz). North, Central, and South America. 
3g. Anterior row of eyes slightly recurved by the posterior margin ; cephalic quadrangle broader than long, 
small eyes much nearer the anterior laterals. Clypeus about half the height of the anterior central eyes. 
Tibia i. with 2—2 spines beneath in the apical half, and two pairs of fine sensory hairs towards the base ; 
tibia ii. with 2—2—2 spines beneat': and some laterals. Protarsi i. and ii. with 2—2 spines beneath, 
iv. armed with three distinct groups of spines. Tibise ili. and iv. with a small dorsal basal spine. Sternum 
about twice longer than broad, rather dilate behind. Mandibles flattened above, transversely rugulose, 
with four small teeth on the upper and three small teeth on the lower margin. Posterior spinners the 
longest; centrals nearly as long, but much more slender ; inferiors as long as the medians, but stouter.
