1874.] NEW SPECIES OF ERIGONE. 437 



indentations (slightly) dusky blackish, the occipital eminence and 

 the upper part of the frontal prominence being black ; some portion 

 of the thorax is minutely punctuose; but the dark part of the caput 

 is very smooth and glossy, and furnished with hairs, mostly directed 

 forwards and backwards over the indentation dividing the lwo lobes ; 

 those on the fore part of the occipital lobe are the most numerous 

 and strongest. The form of the cephalothorax, it will be seen, much 

 resembles that of the European species E. parallela (Bl.) and E. la- 

 tifrons (Cambr.). 



The eyes are in the usual four pairs ; but the position of those of 

 the two lateral pairs is remarkable, being placed much further back- 

 wards than ordinarily ; those of the hind central pair are on the sides 

 of the fore part of the occipital eminence, and separated from each 

 other by an interval of about two diameters ; those of the foremost 

 pair are on the highest part of the frontal lobe, and are nearer to- 

 gether than those of the hind central pair ; and those of each lateral 

 pair are seated contiguously to each other on a small black tubercular 

 prominence, which, however, is very apparent when the Spider is 

 looked at from the front ; when looked at in profile the lateral eyes are 

 placed considerably behind those on the occipital eminence. 



The leys are moderately long, rather slender, of a dull pale orange- 

 yellow colour, and furnished with short hairs. 



The palpi are rather strong, moderately long, and similar to the 

 legs in colour ; the cubital joint is long, rather curved, and enlarges 

 from its hinder to its fore extremity ; the radial joint is very short, 

 but is prolonged at its fore extremity into a long, curved, tapering, 

 sharp-pointed apophysis ; the digital joint is not very large, but of 

 rather a peculiar form, having an angular prominence at its hinder 

 part, near which is a short row of a few black curved bristles, more 

 conspicuous than the rest of the hairs on the joint ; the palpal organs 

 are prominent and well developed, but not very complex, nor present- 

 ing any remarkable feature in structure. 



The falces are small, similar in colour to the cephalothorax, and, 

 owing to the prominence of the fore part of the caput, placed con- 

 siderably backwards under it. 



The maxillae and labium are of normal character, and rather paler 

 in colour than the falces. 



The sternum is of ordinary size and form,similar to the cephalothorax 

 in colour, and apparently covered with small punctures. 



The abdomen is of a flattened oval form ; the larger portion of the 

 upper part is covered with a coriaceous punctuose epidermis, of a 

 dark-yellow-brown colour, pretty thickly mottled with clearer yellow- 

 brown ; four more conspicuous spots of this colour form a quadran- 

 gular figure on the middle ; and behind these are two rather oblique 

 opposed short sinuous similarly coloured lines ; the hinder part 

 (which, as well as the sides, is black) has several very slightly angular 

 pale lines or chevrons between the limits of the coriaceous epidermis 

 and the spinners ; and the sides are longitudinally wrinkled ; the 

 underside is black ; the spiracular plates are orange-coloured and of 

 large size.
