218 Indian Arachnoidca. [No. 4, 



Family, LYCOSID^J. 



DOLOMEDES, Latreille. 



The species of this genus are chiefly characterised by the arrange- 

 ment of their eyes, of which the four anterior are small and in one 

 line, while the four posterior form a trapezoid, narrower in front than 

 behind. Some of the species have short feet and in general character 

 resemble the Lycosce, with which the disposition of the eyes mostly 

 agrees ; other species have long feet and resemble the Philodromi of 

 the THOMismiE, or the Nepliilco of the Epeirid.e. I rather think that 

 a few good generic, or subgeneric, types will have to be distinguished 

 among the forms now referred to Dolomedcs, but my present very 

 scanty materials do not permit me to enter into the details of this 

 question. I shall note only one species which appears to be particu- 

 larly interesting.

9. The cephalothorax is large, more than half the length of the 

 abdomen, roundish oval, slightly convex, narrowly truncated, and sloping 

 in front and behind ; yellowish brown with dark brown margins, and 

 a pair of rather broad longitudinal bands of the same colour in the 

 middle. 



The cephalic region is very little elevated, and not distinctly 

 separated from the posterior, which has a short groove in the centre. 

 The four small anterior eyes are on the front side, they are grouped in 

 two pairs though not well defined ; the four posterior, much larger 

 eyes form, as usually, a trapezoid, the anteriors being the smaller ones, 

 and placed nearer to each other than the posteriors. 



The falces are cylindrical, little shorter than the sternum ; with 

 small claws ; they are yellowish with a longitudinal broad streak of a 

 brown colour. 



The lip is subquadrate, broader than long, sub-truncate in front ; 

 the maxillse are longer than broad, about double the length of the lip, 

 very little broader at their terminations ; the palpi are inserted at their 

 upper bases, they are thin, the 2nd segment being the longest, and next 

 comes the 5th ; all these organs are pale yellowish, covered like the 

 rest of the body with short hairs, only a few of them being blackish. 



The sternum is oval, truncate in front, obtusely pointed behind, hairy,
