Lophocarenum crenatum. 



Determination correct, it now goes in Diplocephalus. 



Lophocarenum crenatoideum. 



Is Diplocephalus crenatum, a d" not fully colored, and apparently 

 longer cephalothorax. 

 Lophocarenum erigonoides. 



Is a Diplocephalus; the male is an immature specimen, and the 

 female is also probably not mature or else belongs to a different 

 species. 



Lophocarenum formosum. 



This is L. erigonoides, I believe, although the palpal organ does 

 not fit Emerton's figure in some parts. I think it is also the Erigone 

 percisa of Keyserling, his figure of palpus is not quite right, but the 

 epigynum is the same as I have figured for formosum (PI. X, fig. 4). 



Lophocarenum arvensis = Comicularia communis Emer. 

 Lophocarenum longior. 



This is apparently a female Comicularia and probably of C. directa; 

 at least I find no differences. 



Tmeticus unicorn. 



This will go in the genus Delorrhipis, but is very different from 

 D. monoceros. A new description is given by Crosby. 



Tmeticus trilobatus. 



Goes in Gonglydiuni. 

 Tmeticus obscurus. 



The tarsi of palpi gone, but from the tibiae it is quite probably 

 T. phlmosus, which has since been taken near Ithaca. 



Tmeticus flaveolus. 



Unchanged; a description, with figures, is given by Emerton in 

 1909 from New England material. 



Tmeticus luxuosus. 



This belongs to Ceratinopsis and is the species described by Emer- 

 ton in 1909 as C. alternatus. 

 Tmeticus rusticus. 



I cannot identify with any described form ; I figure the long slender 

 hook (PL X, fig. 10). 



Tmeticus pallidus. 



Unchanged, but goes in Gonglylidium. 

 Tmeticus humilis = T. plumosus Emer. 



Now in the genus Gonglyidium.
