FRONTINELLA.—BATHYPHANTES. 493 
those of the male of /. eta, but the spur on the patella is very different in shape. 
I can find no examples in the collection which one can confidently refer to this species 
as identified by Emerton. 
7. Frontinella rustica, sp. n. (Tab. XL. fig. 8, 2.) 
Type, 2, in coll. Godman & Salvin. Total length 5 millim. 
This species closely resembles /’. Jeta in general appearance. It is, however, much smaller, and not so much 
produced behind, above the spinners. For the vulva, see Table and Plate. 
Hab. Mexico, Orizaba (H. H. Smith). 
8. Frontinella confinis. (Tab. XL. fig. 9, 2.) 
Linyphia confinis, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 306, t. 35. figg. 9,

Type, 2, in coll. Godman’& Salvin. Total length 5 millim. 
Hab. Guatemata (Sarg 3). 
LEPTHYPHANTES. 
Lepthyphantes, Menge, Preuss. Spinn. p. 131 (1866). 
Type L. muscicola, Menge,= ZL. minutus (Blackw.). Europe. 
The spiders belonging to this genus have a stridulating-organ on the mandible 
composed of a band of regular, definite, parallel strie. ‘The legs are more spinose 
than in Zmeticus and the allied genera; and there is always a protarsal spine and no 
cephalic fovea, as in Bathyphantes. A single species only has been recorded from 
Central America, L. dubia, O. P.-Cambr., belonging to another group of the Linyphiine. 
1. Lepthyphantes longispinosa. 
Leptyphantes lonyispinosa, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 188, t. 23. figg. 8, 
8af(d)’. 
Type, ¢, in coll. Godman & Salvin. Total length 3 millim. 
Hab. GuateMa.a, Coban (Sarg '). 
BATHYPHANTES. 
Bathyphantes, Menge, Preuss. Spinn. p. 111 (1866). 
Type B. longipes, Menge=B. parvula (Westr.). Europe. 
The spiders belonging to this genus have no spines on the anterior protarsus, and in 
the typical species they have, in both sexes, a deep fovea on the anterior lateral margin 
of the carapace. ‘The mandibles are simply striate on the outer side. A single species 
only occurs in the collection before me. B. tragica, Marx, is unknown to me.
