 depressed line on the vertex behind the eyes ; labrum and 

 palpi pale yellow. Antennae with upwards of 25 joints (appa- 

 rently not quite complete), first two joints pale yellow, the rest 

 chocolate-brown; scape dilated, 1^ times longer than broad, 3rd 

 joint slender, at least twice as long as broad, joints 2, 4, 5, 6, 7 

 about as loug as broad, the rest rather longer ; pronotum rather 

 variable, median line generally pale, a pale spot on the lateral 

 margins, between which and the median line is often a smaller 

 and yellower one, towards the extremity ; tegmina with 2 tawny 

 or yellowish dashes near the base, on each side, one near the 

 suture and another on the side ; exposed part of the wings pale 

 yellow, but the greater part filled up, except at the base and at 

 the extreme margins, bj^ a large black blotch, longest near the 

 suture ; abdomen with the segments narrowly edged behind with 

 a red line, from which 6 short, straight, red dashes project ; 

 forceps dull red ; legs pale yellow, the femora, except at the tips,

Described from four females and one male. The male is 

 gTeyer, more strongly punctured, and rather more obscurely 

 marked, and the forceps are curved instead of straight ; other- 

 wise there is but little difl'erence in the sexes. 



Allied to JS. yorkense, Dohrn, and to E. sumatranum, De

 Serv. Ann. Sci. Nat. xxii. p. 31 (1831) ; Orth. p. 32 (1839). 



Type, P.fuscata, Serv., from Cayenne. 



This genus has some resemblance to Thermastris, with which 

 De Bormans unites it; but seems to difl"er by its more slender 

 form and concealed scutellum. It is perhaps more nearly related 

 to LaUdura. It is unknown to me except from Serville's 

 description and figure of the type.
