The colour of this species is not quite satisfactorily described 

 by Westring; the following particulars may therefore be added to 

 his account. In ? the cephalothorax is brownish yellow, with 

 black borders and a black longitudinal central line, which is triangu- 

 larly enlarged in front, and does not reach fully to the eyes. The 

 eye-area is also black. The colour of the legs is accurately describ- 

 ed by Westring. The palpi are of the same colour as the legs, 

 yellowish, with black rings, the mandibles and maxillse also yellow- 

 ish. The sternum is blackish yellow. The abdomen, which just before 

 the oviposition is very highly arched, short, inversely ovate, but at 

 other times more elongated, has in a peculiarly fine specimen the 

 following marking. The upper part is black, with 4 pair of obliquely 

 placed yellowish lines curved in the form of an S , whereof the anterior 

 are free, the posterior united two and two at their anterior extre- 

 mities: behind them, above the yellowish spinners, is a large, yel- 

 lowish, almost triangular spot, with a series of (about 3) small 

 black angular lines in the middle. The black dorsal area is in 

 front, on both sides, bordered by a yellowish band, from which three 

 lines or bands of the same colour go obliquely down the dark sides; 

 beneath these bands, which are sometimes free, there are on the 

 sides of the belly two or three yellow spots or stripes of various 

 sizes; along the middle of the belly goes a broad, yellowish band, 

 gradually narrower behind, and near it a fine, shorter, light line 

 on both sides. In another specimen the oblique lines on the poste- 

 rior part of the sides of the abdomen are wanting: the great yellow 

 spot above the anus is replaced by two smaller, with a few 

 small yellow angular lines between them: the whole underside of 

 the belly is yellow. In an English specimen the ground-colour is 

 much lighter, more irregularly mottled with black: a large almost 

 t-formed blackish mark bordered by yellow longitudinal spots is seen 

 on the upper part of the abdomen, in front. — The vulva forms a 

 tolerably short, thick, projecting reddish-brown tubercle. 



In the male, which in other respects is similar to the female, 

 the proportion of the legs seems to be 1, 2, 4, 3. The pars patel- 

 laris and pars tibialis of the palpus are both very short, the former 

 very convex on the anterior side, with a long, fine bristle at the 

 apex: the clava is very large, rounded, and its diameter double that 

 of the thigh; at its base, on the anterior side, near the tibial 

 joint, it shows a small, coarse, truncated tooth ; its colour is reddish 

 brown; the other joints of the palpi are pale reddish yellow.
