Genus Lithyphantes, Thor. 

 Lithyphantes lepidus, sp. n. (Plate LIII. fig. 9.) 



Length of the adult male rather less than 1| line. 



The cephalothorax is of a broadish-oval form, moderately convex 

 above, and the profile line ascends gradually from the hinder extre- 

 mity in a very nearly even straight line to the ocular area ; the fore 

 part of this area, containing the fore-central pair of eyes, is very pro- 

 minent, causing a deep indentation in the profile of the clypeus, whose 

 height, otherwise, exceeds half that of the facial space. The lateral 

 marginal constrictions are slight, as are also the normal indentations. 

 The colour of the cephalothorax is deep blackish brown. 



The eyes are of moderate size ; those of the hind-central pair are 

 nearer together than each is to the hind-lateral eye on its side, 

 being separated by less than a diameter's interval ; those of the fore- 

 central pair are smallest of the eight, and are seated in front of a 

 largish somewhat roundish protuberance ; they are wider apart than 

 the hind-centrals, though forming a line scarcely as long. The fore- 

 and hind-central eyes form a trapezoid whose length is greater than 

 its breadth ; those of each lateral pair are placed slightly obliquely 

 on a strong tubercle. 



The legs are not very long, moderately strong (I, 4, 2, 3). They 

 are of a dull yellowish-brown colour tinged with olive. The femora 

 are much darker than the other joints, being of a dark blackish- 

 brown hue ; the fore extremities also of the tibiae and metatarsi are 

 tinged with the same colour. The armature consists of hairs only. 



The palpi are short, and of a dark brownish colour ; the radial 

 is stronger than the cubital joint, and enlarges to its extremity, 

 where it joins in closely with the digital joint : the digital joint is of 

 tolerable size and of an oval form ; the palpal organs are rather com- 

 plex, though compact ; and, though showing several prominent points 

 and processes, there is not one of any remarkable character. 



They«/ces are long, strong, prominent at their base in front, and 

 project a little forwards. The fang is long, strong, somewhat si- 

 nuous ; and instead of lying (when at rest) along the inner edge of 

 the falces, appears to stretch and remain across it at right angles 

 towards the extremity of the opposite falx. Their colour is paler 

 than that of the cephalothorax. 



The maxillce are strong, slightly curved, inclined to the labium, 

 their colour being like that of the falces. 



The labium is short, semicircular, and with the sternum (which is 

 oval, somewhat truncated before) similar in colour to the cephalo- 

 thorax. 



The abdomen is oviform, not very convex above, and projects but 

 slightly over the base of the cephalothorax. The upper part and 

 sides are black, with three longitudinal white bands broken into 

 more or less distinct separate patches ; the central band is the 

 strongest, the others forming a margin on each side of the upper 

 part of the abdomen : all these bands unite at the fore extremity. 

 The underpart is of a browner tinge, and has an indistinct marginal
