anterior coruers considerably rounded, the posterior edge slightly 

 emarginate; basal lamina scarcely three times as broad as long. 



Labrum joined at its lateral angles to the frontal lamina, anterior 

 and posterior edges convex outwardly ou each side of the middle; ends 

 of the labrum deeply and acutely notched at the point where they meet 

 the supports {laminos fulcientes). The anterior margin has two deep 

 notches which run behind the arch of teeth. Teeth about fifteen ; 

 starting from the posterior edge of the labrum are several transverse 

 wrinkles which run across to near the anterior edge, where there are a. 

 few long transverse wrinkles. 



Mandibulary stipe with a few spines beyond the last dentate lamella, 

 giving the appearance of another small pectinate lamella. Teeth of 

 dentate lamellae sharp-pointed, especially those distant from the pecti- 

 nate lamella. 



Prehensorial feet not reaching the frontal margin of head ; sternum 

 broader than long (9 : 7), nearly twice as long as coxa (7:4); anterior 

 margin medianly broadly sinuate, with nearly obsolete concealed teeth ; 

 coxa and two succeeding joints each with an acute tooth; claw 

 strongly curved, with a nodiform tooth at base. 



Scuta not sulcate ; anterior prescuta moderately long, the middle 

 and posterior very long, except the last three. 



Spiracles largest in front, 0.045 millimetres in diameter, gradually 

 decreasing posteriorly to 0.03 millimetres. 



Sterna, anterior, deeply bisulcate, and with a deep median foveola ; 

 these depressions become gradually less pronounced posteriorly. The 

 foveola becomes obsolete on the middle segments, but shows a ten- 

 dency to reappear near the end of the body. 



Pleurae of last segment moderately inflated, with about twenty-five 

 pores, which differ much in size (0.01 to 0.04 millimetres in diameter). 

 Last sternum narrow, oblong, the posterior angles rounded, the sides 

 scarcely converging. 



First pair of legs shorter than the second ; anal legs longer than the 

 penultimate, sparsely clothed with longer hairs, strongly decurved, as 

 are all the legs, armed with a large claw, not enlarged in the female. 



Anal pores present. 



Pairs of legs in the female forty-one ; length of body 32 millimetres, 

 greatest breadth 1.3 millimetres. 



Described from two females found among fallen leaves near Oak- 

 wood Cemetery, Syracuse, New York, January, 1890. 



The considerable number of characters which this species has in 

 common with GeophUus urhicns Meinert* makes it appear probable that 

 that species belongs under the present genus. There is nothing to 

 indicate that Meinert dissected the mouth parts of the single specimen 

 in the Cambridge collection. Should our suspicion prove to be well
