216 Indian Araclmoidea. [No. 4, 



It is difficult to find an appropriate position for the genns, but from 

 the general appearance of the body and the distribution of the eyes, it 

 seems to me that Hersilia has a great relation to Linyphia. Its habits 

 are, however, very similar to those of Philodromus, and the same is 

 the case as regards the proportionate length of the feet ; it may, 

 therefore, be also correctly placed near, or in, the family Thomisid^e. 



There are several species found all through India, Burma and the 

 Malacca straits. I have observed them mostly on palm-trees, the bark 

 of which they much resemble in colouring ; they are sometimes also 

 called mangoe spiders. 



Hersilia Calcuttensis, Stoi. PL XX., Fig. 9. 



cj>. Cephalothorax scarcely broader than long, the ocular region 

 narrow and strongly elevated, the posterior region with the lateral 

 margins strongly curved, with one longitudinal central and two 

 transverse fine grooves ; the anterior part is the smaller. The grooves 

 and the margins are partially dark brownish, the rest is yellowish, 

 thickly covered with short white hairs. 



The eyes are in exactly the same position as in the type species ; the 

 two anterior on each side form with the posterior laterals an ascending 

 triangle, and the anterior laterals are very small, situated in front and 

 below the posterior laterals ; of all the eyes the anterior centrals are 

 the largest. The immediate region round each eye is dark brown. 



The falces are shorter than the sternum, sub-cylindrical, at the base 

 rather contracted, pale brown with moderate dark brown claws. 



The lip is broadly semicircular, short ; the maxillae semewhat 

 higher, thick at the base, attenuated towards their ends and strongly 

 converging. The palpi are thin, more than double the length of the 

 falces ; they are yellowish with black tips ; the lip and maxillae are a 

 little darker than the other organs. 



The sternum is almost broader than long, flat, greyish brown, 

 thickly set with hairs, anteriorly emarginated, posteriorly obtuse, 

 The feet are slender and very long, the first being the longest, then 

 the second, which is only a little shorter than the fourth, and then comes 

 the third which is about equal to one-half of one of the second pair. 

 The colour is pale yellowish with dark terminations to the joint. 

 No bands are traceable.
