176 J. H. Emerton, 
which Simon refers to Prosopotheca, and also, as suggested by 
Simon, Spiropalpus spiralis which, though its male has no horns, 
resembles this genus. 
Grammonata includes, besides the three species before described, 
Erigonoplus gigas Banks, which has lately been found in Massa- 
chusetts. All the species resemble Amaurobius in form and mark- 
ings, having an indistinct pattern of light spots on the abdomen. 
In the males the head is a little elevated behind the eyes, and in 
pictilis and gigas there is a conspicuous hump. The males of gigas 
have the first metatarsus white and much thicker than the other 
joints. The male palpi resemble those of Ceratinella, having a long 
tube turned abruptly backward from the end of the tarsus. In 
pictihs the tube is very long and coiled in a double spiral. 
Diplocephalus Bertkau, 1883, is Lophomma Em. of N. E. Theri- 
didae, in which the males have two humps on the head, each 
carrying one pair of the middle eyes. The male palpi have the 
tibia very large, covering the back of the tarsus nearly its whole 
length. 
Lophocarenum consists of those spiders, the males of which, 
except rugosum, have holes in the head behind the eyes, and the 
middle of the head elevated, sometimes into large humps. The 
male palpi have the patella longer than the tibia, and the latter 
usually longer than wide, with small hooks and processes of various 
shapes. Where the enlargement of the head of the male is extreme, 
the female has a slight elevation of the head as in montiferum and 
alpinum. The unusually large size of the front lateral eyes in 
quadricristatum occurs in a less degree in the female. 
There is no better example of the difficulty of classifying the 
Erigonee than the attempt of Simon to distribute the American 
species of this genus, without seeing the spiders themselves, among 
eight different genera. For florens he makes a new genus Ayp- 
selistes, while decemoculatum, the females of which cannot be dis- 
tinguished from those of florens, is placed in Nertene, which cor- 
responds in part to my Tmeticus. L. pallidum and L. longitubus, 
which resemble each other as closely as any other two species, 
are placed one in 7yphocrestes and the other in Pocodicnemis. L. sco- 
puliferum is placed in Minyriolus, L. quadricristatum in Pana- 
momops, L. longitarsus in Lophomma, L. rostratum in Trachelo- 
campitus and L. decemoculatum, montiferum and spiniferum in 
Neriene. \ see no reason to follow any of these changes; they 
only obscure the relations of the spiders. 
Tmeticus is still a heterogeneous group. The more typical species,
