PHILODROMUS, Walck*. 



The Philodromi dilVer from tin- two pivr.-ding subgenera in their 

 jaws, whieh an- inclined on tin- litfula, which is also higher than it 

 H wide. The almo.st i'i|ual ryes always form a crescent or semi- 

 eirel\ Tin- lateral one* arc nevT placed on tubeivlrs or rminences. 

 The ehalicerae are - i and cylindrical: the four or two last 



legs do not materially diner in length i'roni the others. 



rdin-4 ti. Walckenaer the>e ajiimaU run with great swiftness, 

 tln-ir le<4's extended laterally, lie in wait for their prey, throw out 

 solitary threads to entrap it, and conceal themselves in crevices or 

 among leaves. 



In some the body is broad and flat, the abdomen short and 

 widened posteriorly, and the four intermediate legs the longest. 

 Such is the I'/ii/utlmme tigree ; Thomise tigre, Lat. ; Araneus 

 margaritarius, Clerck, VI, iii ; Schaeff., Icon., Ixxi, 8; Frisch. 

 I UN., Crntur., II, xiv; Aranea levipes, L. ? It is about three 

 lines in length. Its two anterior intermediate eyes and the 

 four lateral ones are situated on a slight elevation, and the lat- 

 ter, according to the same naturalist, are somewhat the largest, 

 or at least are more apparent. The thorax is very wide, flat- 

 tened, of a reddish fawn colour, brown laterally and posteriorly, 

 and white anteriorly. The abdomen, which forms a kind of 

 pentagon, is speckled by the red, brown and white hairs which 

 cover it, and edge laterally with brown; there are four or six 

 impressed points on the middle of the back. The belly is 

 whitish, and the legs are long, slender and reddish, with brown 



'tS. 



This species is very common on trees, wooden partitions, walls, 

 &c., where it remains as if glued, with the feet extended. If 

 touched, it runs with astonishing rapidity, or falls to the ground 

 supported by a thread. The cocoon is of a beautiful white, and 

 contains about a hundred eggs, which are yellow and free. The 

 f'milr plae.'s it in hollows of trees or clefts of posts, &c., ex- 

 1 to the north, and carefully watches it. 



The other Philodromi, which, according to the method of M. 



\Val-krna'T. i'nnu M-veral small groups, have the body, and some- 

 times tin- ehrlieri.r, proportioiiably longer. The abdomen is some- 

 tiiin'-N j.yriionn oi ovoid, and sometimes cylindrical. The second 

 pair of legs and then the first or the fourth are the loni,

 reddish; the second legs and then the two last are the longest; 



* la the first edition of tbis work, this buhgenus formed our first division of the 

 Thombi.
