176 J. II. Emerton, 



which Simon refers to Prosopotheca, and also, as suggested by 

 Simon, Spirupalpus 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 Amaiirobius 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 hum)). The males of gigas 

 have the first metatarsus white and much thicker than the other 

 joints. The male palpi resemble those of Ccratiiwlla, having a long 

 tube turned abruptly backward from the end of the tarsus. In 

 pictilis the tube is very long and coiled in a double spiral. 



Di place phahts Bertkau, bS8ii, 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 

 alpinnm. 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 

 Erigoneee than the attempt of Simon to distribute the American 

 species of this genus, without seeing the spiders themselves, among 

 eight different genera. For Jlorens he makes a new genus Hyp- 

 selistes, while decemoculatum, the females of which cannot be dis- 

 tinguished from those of Jlorens, is placed in Neriene, 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 Typhocrastes and the other in Pocodicnemis. L. sco- 

 puliferum is placed in Minyriolus, L. quadricristatum in Pana- 

 momops, L. longitarsus in Lophomma, L. rostratum in Trachclo- 

 camptus and L. decemoculatum, montiferum and spinifcrum in 

 Neriene. I see no reason to follow any of these changes ; they 

 only obscure the relations ol the spiders. 



Tmeticus is still a heterogeneous group. The more typical species,
