sub-order T'etrapneumones, but the fact that it spins a web Uke a Tubi- 

 ielaria excludes it from the TerritelaricB and demands at least a new 

 family. 



I have named this interesting spider, at the suggestion of Prof 

 Thorell, Hypochiliis, and, in appreciation of this distinguished naturalist, 

 Hypochihis ihordlii, and the new family I have called Hypochilidce. 



Family HYPOCHILIDiE, nov. gen. 



Four lamallar trachea;, the anterior pair close the base of the abdomen, the 

 posterior in the middle retiion of the venter. .Mandibular claws nearly vertical. Legs 

 long and slender. Cnbelkim and calamistrum present. 



Spiders which make saucer- or lampshade-like webs. 



HYPOCHILUS, nov. gen. 

 Hupo below, cheilos lip : from the position of the labium. 



Cepha'.K with a flattened dorsum, depressed in the median region ; sub- 

 circular, posteriorly slightly emarginate ; pars cephalica rising abruptly. Eyes, 8. 



3 in a cluster on each side and two in the middle between them ; the anterior lateral 

 eyes about as far from the margin of the clypi-us as their diameter. These eyes are 

 directed downward. The two middle eyes a little lighter than the anterior lateral. 

 Mandibles cylindrical, slightly tumid in the middle region. Claws long, nearly 

 vertical. Maxillre longer than broad, parallel ; palpus inserted in the middle of the 

 external boider. Labium broad, short and straight, situate below the maxilla 

 which stand upon it. Abdomen long, subcyiindi-ical ; cribellum semicircular, un-

 median eyes black, the others large and white.

 inner borders, truncate at the tip and standing with their narrow and pointed base 

 upon the labium. Sternum ovate, truncate anteriorly by the broad labium, its sides 

 with depressions and a blunt point between coxte IV. Palpi long, equal to meta- 

 tarsus II. Abdomen — upperside mottled with black indistinct lines and figures which
