" Corium elongate, a little more than one-third of the total 

 length of the hemelytra ; marginal cell transparent, straight, long, 

 at least three times longer than broad, hardly broader than the 

 discoidal cell ; membrane strongly darkened with a large pale 

 marginal spot situated a little after the middle of the total length 

 of the hemelytra and some small pale indistinct rounded spots 

 near the disk ; nervures indistinct, as in P. unicolo}\ Montaud., 

 a little more plainly prolonged behind, the aperture between the 

 discoidal veins clearly directed towards the posterior border of 

 the membrane, within the posterior external angle, forming a 

 median apical cell not closed at the extremity, the smooth shiny 

 vitreous part of the membrane behind the corium straighter, less 

 trans]jarent and less visible than in the preceding species \P. v.nicolor 

 and P. suhreticidams, Montand.]." (Montandon.)

" This species somewhat resembles the figure given by West\\'ood 

 (Thes. Entom. pi, xxxvi, f. 9) of his Holoptilus burmankus, which 

 is certainly a Ptilocerus, but in the drawing referred to, the veins 

 of the corium appear of a very dark colour and prolonged behind 

 on the vitreous space of the membrane behind the corium, and 

 this vitreous space appears more enlarged than in P. umhrosus, in 

 which the veins are less visible and '\\hich has besides two large 

 pale spots on the margin, whilst it is entirely and almost uniformly 

 dark in P. hunnanicus, &c." (Montandon.)
