mark on the pars cephalica ; the abdomen is dark brown on the sides ; 

 its upper part is in d* greyish or paler brown, with a dark brown 

 lancet-formed central band in front, which exhibits two or three 

 small white longitudinal spots on both margins: this band is con- 

 tinued by another broader band, narrowing towards the anus, in 

 which a series of more or less conspicuous, angularly curved, pale 

 lines may be observed. In the female a similar pattern may sometimes 

 be seen on the abdomen; sometimes the entire back is brown, only 

 with a darker lancet-formed band in front, and a row of small dark 

 angular marks behind it. There are four dark points forming a tra- 

 pezium on the anterior half of the back, as in Ph. aureolus. The 

 brownish-yellow legs have conspicuous, darker rings. 



In the two adult females that I have seen, the vulva has the form 

 of a small, somewhat transversal, brown area, which at its hinder 

 margin exhibits two black uneven elevations or short costse, one on 

 each side. In Ph. aureolus on the contrary it consists of a large 

 pale fovea or area, bounded at the sides by two coarse black trans- 

 versely striated costa? curved inwards, towards each other, and exter- 

 nally bordered with a brown longitudinal spot emarginated towards 

 the middle. The tibial joint of the palpus in Ph. auro-nitens cf is 

 a trifle longer then the patellar joint, fully double as long as it is 

 broad, and, when viewed from the side, of uniform thickness, not 

 dilated at the apex; it has at the extremity, on the exterior side, a 

 process in the form of a slender, almost uniformly thick, shortly 

 pointed, black spine, and a little below it a short, conical, black 

 tooth. At the extremity, on the under side, it has a somewhat broader, 

 pointed process, the extremity of which is depressed, and which, 

 viewed laterally, presents the appearance af a strong and sharp 

 spur curved somewhat upwards. In Ph. aureolus cf the tibial joint 

 is rather shorter than the patellar, not fully double so long as broad, 

 somewhat dilated at the apex, when viewed from the side. The exte- 

 rior process forms a more powerful spine, tapering more gradually from 

 the base outward; the inferior process is broad and short , broader than 

 it is long, broadly (and often more or less obliquely) truncated 

 (see above, p. 165), transversally depressed; at its base, on the 

 outer margin, appears a conical black tooth, and on the opposite 

 margin, nearer the apex, a little protuberance: viewed from the 

 side it presents the appearance of a shorter, coarse, somewhat up- 

 turned hook. — In Ph. aureolus $ the legs are usually of a uniform 

 brownish yellow colour, rarely having indistinct darker rings.
