part of the body is yellow with two black "eye-spots;" sides black with 

 transverse marks of yellowish white ; dorsal stripe bright red, commenciBg 

 higher up than in the adult, and with the edges serrated ; thorax dark brown ; 

 under parts black with an obscure spot of red ; legs yellowish brown, black at 

 their joints. At a more advanced age, the stripe on the back is brighter and 

 is narrowly bordered with yellow, and there are some obscure markings on the 

 sides. In this condition the thorax and legs are nearly black. 



ASmU Female. — Examples differ considerably in size, the body which is 

 almost spherical, varying in development from the size of pigeon shot to that 

 of a small green-pea. In the fully adult condition, this spider is a very 

 handsome one, both in form and colour. In my largest specimens, the 

 outspread legs, measuring across, cover a space of three-quarters of an inch. 

 Thorax and body shining, satiny black. A stripe of bright orange-red passes 

 down the centre of the body, the edges being tinged with yellow. At the 

 anterior extremity, this stripe is broader and angular, and it is surmounted by 

 an open, narrow mark of white in the form of a nail-head. Below this, and 

 immediately above the junction of the thorax there are two divergent spots of 

 orpiment yellow with white edges. Legs black, with the extremities inclining 

 to brown. On the under stirface there are two transverse spots of dark red. 

 In some examples there is a dark line down the middle of the bright dorsal 

 stripe, while in others the sides are ornamented with transverse marks of 

 yellowish white. One of the specimens in my collection, more beautiful than 

 the rest, has two triangular spots of yellow above the junction of the thorax, 

 then two letter V marks with their angles joined, succeeded above by two 

 similar but larger marks, their inner ai'ms forming the nail-head which caps 

 the bright dorsal stripe of red. 



Adult Male. — The male is considerably smaller than the female. Body 

 shining blackish brown, with an obscure narrow line of yellow down the centre 

 of the back, broader towards the posterior extremity, and a similar interrupted 

 line on each side ; legs dark brown, with black joints.
