180 Mr. J. Bkckwall on some new species of Araneidea. 



Mas foemina minor, pallidior, maculis fasciisque obscurioribus : maris 



par pedum primum 4*° longius. 



Length of the female, not including the spinners, ^ths of an inch ; 

 length of the cephalo- thorax -5^^ ; breadth /g ; breadth of the abdo- 

 men ^ ; length of a posterior leg 1 1 ; length of a leg of the third 

 pair 1. 



The anterior part of the cephalo-thorax is compressed, and the 

 posterior part is marked with furrows diverging from a narrow 

 indentation in the medial line to the lateral margins, which are 

 rounded ; it is thickly covered with hairs, and is pale yellowish 

 brown, with a fine line extending along the middle of the anterior 

 part, a broad, irregular, longitudinal band on each side, and la- 

 teral margins of a dark brown colour. Eyes almost equal in size, 

 disposed in two transverse rows on the anterior part of the ce- 

 phalo-thorax ; the anterior row is rather the shorter and nearly 

 straight ; the posterior row is curved and has its convexity di- 

 rected backwards; the intermediate eyes of both rows form a 

 square nearly, the anterior ones being rather the largest of the 

 eight ; the eyes of each lateral pair are seated obliquely on a small 

 eminence, but are not contiguous. Mandibles powerful, conical, 

 vertical, provided with two rows of teeth and some long hairs on 

 the inner surface ; they are of a dark reddish brown colour ap- 

 proaching to black. Maxillae straight, increasing in breadth from 

 the base to the extremity, which is rounded on the outer side, 

 and obliquely truncated and supplied with long hairs on the inner 

 side : lip quadrilateral, longer than broad, slightly notched at the 

 apex : these parts are reddish brown, the lip being the darkest, 

 and are palest at their extremities. Sternum heart-shaped, with 

 a red-brown band extending along the middle, which decreases 

 in breadth to its posterior extremity, and a large dark brown se- 

 milunar band on each side, comprising several circular red-brown 

 spots opposite to the insertion of the legs. Legs long, hairy and 

 reddish brown, with the exception of the thighs of the second, 

 third and fourth pairs, which are of a dull greenish brown colour ; 

 several black spots occur on the under side of each haunch ; fourth 

 pair the longest, then the first, third pair the shortest. Each 

 tarsus is terminated by three claws ; the two superior ones are 

 curved and pectinated, and the inferior one is inflected near its 

 base, which is furnished with several fine teeth. Palpi dark red- 

 dish brown, with a curved pectinated claw at the extremity. Ab- 

 domen oviform, hairy, convex above, projecting over the base of 

 the cephalo-thorax ; along the middle of the upper part extends a 

 series of yellowish brown angular lines, which become shorter 

 and less conspicuous as they approach the spinners ; their vertices, 

 which are directed forwards, are interrupted at the anterior part 

 of the series by a longitudinal band of yellowish brown, and with
