Posterior eyes in a strongly procurved line, equal and equidistant, 

 separated by their diameter; anterior eyes in a procurved line, the 

 median eyes a little smaller than the lateral, subcontiguous, separated 

 from the lateral by less than their radius. Median ocular area as wide 

 as long. Clypeus measured from the lateral eyes narrower than the 

 ocular area. This species is closely allied to D. percisus Keys., if not 

 identical with it. I have specimens from Columbia, Missouri, and 

 Ithaca, New York. 



TAPINOCYBA. 

 Tapinocyba distincta Banks. 



In the absence of the male it is with great doubt that I refer this 

 species to Tapinocyba. It is related to it by the curvature of the pos- 

 terior row of eyes, by the form of the median ocular area and by the 

 narrow ch'peus as well as by the proportionally long tarsi of the legs 

 (see under GongylidieUum minutuvi).

Posterior eyes in a slightly procurved line, equal, the median eyes 

 a little farther from each other than from the lateral, interocular spaces 

 less than the diameter of the eyes; anterior eyes in a straight line, the 

 median eyes much smaller than the lateral, subcontiguous, but sepa- 

 rated from the lateral by their diameter. Median ocular area longer 

 than wide. Clypeus one-half as wide as ocular area. 



POCADICNEMIS. 

 Pocadicnemis longitubus Em. (PI. XXIX, fig. 3.) 



This species has been doubtfully placed in this genus by Simon {Ar. 

 Fr., V, p. 718, and Hist. Nat. Ar., I, p. 617). In the male the posterior 

 median ej^es are nearer each other than to the lateral and the tibial 

 spines are rather short, otherwise it agrees with the European forms. 

 The posterior eyes are in a strongly procurved line, the anterior eyes 

 are in a straight line and the anterior tarsi are three-fifths the length 

 of the metatarsi. The female is undescribed.
