Posterior eyes in a recurved line, the median eyes oval, a little larger 

 than the lateral, separated from each other by their diameter and from 

 the lateral by nearly twice as much; anterior eyes in a recurved line, 

 the median eyes much smaller than the lateral, subcontiguous and 

 separated from the lateral by two-thirds their diameter. Median 

 ocular area a little longer than wide. Clypeus a little wider than ocular 

 area. 



This species has been referred with doubt to this genus by Simon. It 

 is related to TypJiochrcestus in having the posterior median eyes nearer 

 each other than to the lateral. This arrangement, however, may be 

 the result of the abnormal development of the head in the male. In 

 the absence of female specimens, by which alone this point could be 

 decided, I leave it doubtfully in Trachelocamptus. 



HYPOMMA. 



' Dicyphus Menge, preoccupied. 



I have been unable to examine specimens of the species included in 

 this genus. Dicyphus was founded by Menge (Prevss. Spirm., p. 221, 

 1869) for three species in the following order, tumidus, cilunculus and 

 bicuspidatus, without indicating the type. In 1884 Simon (Ar. Fr., V, 

 p. 546) designated tumidus ( = hitubercidotus) as the type. Dahl 

 (Monographie der Erigonc-Arten, p. 87, 1886) proposed the genus 

 Hypomma for bifrons Blackw. and bituberculatus Wid., without indi- 

 cating the type. Chyzer and Kulczynski (Ar. Hung., pp. 99, 100) seem 

 to consider bituberculatus as the type of Hypomma and cornutus as 

 the type of Dicyphus. As Dicyphus is preoccupied in the Hemiptera 

 (Fieber, Wien. Ent. Monats., II, p. 327, 1858) it is necessary to use 

 the next oldest name applied to that group of species. This seems 

 to be Hypomma. Simon has placed bituberculatus under Gonatium.
