LEIOBUNUM. 583 
Colour. Body and coxe of legs dull orange, dusky above the opisthosomatic dorsum, sometimes with a broad 
central pale band; eye-tumulus black, with a dusky blotch between it and the margin of the clypeus. 
Mandibles black ; digits yellow, with black tips ; femur, patella, and dorsal area of tibia of palpus black, 
tarsus yellow ; trochanters and the whole of the legs pitchy-black. 
2. Generally similar to the ¢, but more granulose, especially beneath, with a row of granules on each side 
of the so-called genital plate. Femur and patella set with short spines, chiefly dorsally, but the femur 
bears many beneath, the tibia also sometimes bearing one or two beneath; tarsus without cuspules 
beneath, and the terminal claw without denticles, or only the rudiments of them. Femora of legs, as in 
the $, armed with minute cusps. 
Colour. Body, mandibles, and palpi, except eye-tumulus, which is black, entirely dull orange; legs pitchy- 
brown. 
Hab. Mexico, Orizaba, Omilteme, Amula, Chilpancingo, Cuernavaca (H. H. Smith). 
2. Leiobunum foveolatum, sp. n. (Tab. LIV. figg. 18, 18a, 2.) 
Type 3, gynetypeQ, in coll. Godman & Salvin. Total length, ¢ 5, 2 3 millim.; leg ii., 2, 100, femur ii. 
20 millim. 
3. General characters as in L. fuluum, but the eye-ridges without cusps. Dorsal integuments covered with 
comparatively large fovee. Coxe of legs and ventral segments granulose, the former with marginal 
rows of granules, but without spines ; genital plate covered with foves, each with a central fine short seta. 
Palpi: femur, patella, and tibia with a few minute spines, the patella having a long blunt spur at its 
inner apical angle; tarsus without a row of cuspules beneath. Legs, except the two terminal segments, 
covered with minute cusps. 
Colour. Dull orange; eye-tumulus, trochanters of the legs, the two posterior prosomatic segments, and a 
lateral dorsal blotch, black; legs dull orange and pitchy-brown. The body sometimes entirely black 
or orange. 
©. Similar to the ¢, but larger. 
Hab. Mexico, Teapa (fH. H. Smith). 
3. Leiobunum dromedarium, sp.n. (Tab. LIV. figg. 19, ¢; 20, 9.) 
Type do, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 4, 2 6 millim.; femur of leg ii, 
¢@, 6 millim. 
g. Clypeus simple ; ridges of eye-tumulus and anterior area set with numerous spinules ; body-segments 
dorsally set with numerous spinules or cusps, the last two prosomatic and the first two opisthosomatic 
segments being somewhat ridged and prominent ; genital plate, coxe, trochanters, femora and patelle 
of legs set with minute cusps; palpi with a few spines on the femur and tibia, the tarsus with a row of 
minute cuspules beneath, the tarsal claw minutely pectinate. (This is possibly an immature example, 
though the penis is well-developed.) 
2. Similar to the ¢, but the dorsal tubercles are much more developed and the spinules more numerous. 
The spinules on the palpi are stronger, but there are no cuspules beneath the tarsi; tarsal claw pectinate. 
Tibia of leg ii. in both sexes with a single median false-articulation. 
Hab. Mexico, Teapa (H. H. Smith). 
4. Leiobunum fulvum, sp. n. (Tab. LIV. figg. 21, ¢; 22, 2.) 
Type 3, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 4, 9 5 millim.; leg ii, g, 20; femur ii., 
2,16 millim. 
g. Clypeus unarmed ; eye-tumulus longitudinally grooved, each eye-ridge with two small cusps; dorsal 
surface of body densely and coarsely granulose ; coxe of legs, genital plate, and other opisthosomatic 
ventral segments studded with numerous scattered minute cusps; the coxe with marginal rows of
