Superfamily Argiopoidea 



near Miami, Fla.), I found an adult female in a nest, made near 

 the top of a dead, finely branching herb. The nest was a tube 

 with compact walls formed by closely weaving together the fine 

 branches of the herb (Fig. 650). 



Chiracantbium albens (C. al'bens). — I have not seen this 

 species. The following is the original description of it by Hentz, 

 who found it in Alabama: 



" Pale bristly; abdomen deeper in colour, venter with its base 

 and three spots, pale green ; pectus with a line each side, pale green ; 

 nipples, four long ones and two short. Feet, very long and 

 slender, 1, 4, 2, 3. First much the longest." 



Subfamily LIOCRANINiE (Li-o-cra-ni'nae) 



In this subfamily the tibiae and metatarsi of the first two 

 pairs of legs are armed, on the lower side, with a definite double 

 series of long spines; usually there are more than two pairs of 

 these spines under each of these tibiae. As in the preceding sub- 

 family, the last segment of the hind spinnerets is distinct and 

 conical; but in this subfamily the labium is not at all or barely 

 longer than wide, and does not extend beyond the middle of the 

 endites. The endites are not narrower in the middle than at the 

 end. 



One half of the genera of clubionids represented in our fauna 

 belong to this subfamily. Our genera can be separated as follows: 



TABLE OF GENERA OF THE LIOCRANIN^ 



A. Tibiae of the first two pairs of legs with a double series of 



long spines, in which there are more than two spines in 



each row. 



B. Sternum large and prolonged behind between the posterior 



coxae; anterior row of eyes procurved; all tarsi lacking 



scopulae, but furnished under the claws with very small 



bundles of from six to ten tenent hairs. P. 576. 



Phrurolithus 

 BB. Sternum normal, not prolonged behind between the 

 posterior coxae, which are nearly contiguous; anterior 

 row of eyes straight or recurved ; tarsi, at least the anterior 

 ones, furnished with scopulae. 

 C. Claws of posterior tarsi not accompanied by large bun- 

 dles of tenent hairs.
