segment jeilowish or pale brownish-yellow ; on the sides, at the base, broadly 

 black ; external processes pale yellowish-white, somewhat thickly clothed with 

 long white hairs. Length, J , 2 ; ? , 2? lines. 



Very similar to P. scutellatus, which insect has the pronotum 

 invariably darker. P. nassatus has somewhat a hoary appearance 

 when in repose, and viewed from above. Grermar's figure is very 

 bad, as is also his description. 



Not unfrequent. Taken by Mr. Douglas and myself at the 

 sallow pit, Lee, Dartford and "Weymouth, in August.

Pale testaceous, shining. 



Head pale yellowish or yellowish-white. Face with from four to seven black spots, 

 placed two (or three) on the upper margin of the crown, two at the margins of 

 the ocelli sometimes, and two, more approximating than the others, in a Une 

 with the lower margin of the eyes, either rhomboidal or comma-shaped. 



Thorax : pronotum — disc more or less dark fuscous or black between the crenidation. 

 Scutellum yellow, with a black triangular spot near each basal angle, and, 

 generally above the transverse channel, two small black or dark brown pvmctures. 

 Elytra (in repose) pale testaceous, or with a faint brownish tinge ; clavus and 

 corlum — nerves stout, dark pitchy-brown, finely punctured on each side ; mein- 

 hrane — nerves finer and paler than those on the corium. Legs testaceous or 

 pale brownish ; thighs — 3rd pair on the lower margin, next the apex, sometmies 

 with a short dark streak ; tibics — 3rd pair at the base, exteriorly, with a black 

 spot ; tarsi yellowish or pale brownish. 



Abdomen above, black, posterior margin of the segments narrowly yellow ; beneath 

 black, posterior margin of the segments more or less broadly yellow ; last 

 genital segment black, lower margin narrowly, and posterior margin broadly 

 testaceous, or pale brownish-yellow ; external processes pale brownish, inter- 

 nally clothed with long white hairs. Length, 2 lines. 



Slightly smaller than P. nassatus, to which it bears a very great 

 resemblance ; it has, however, a darker coloured pronotum than that 

 species, and the nerves of the elytra stouter and punctured on either 

 side. Bohemau only mentions four black spots on the face, but all 

 other authors, who apparently recognise and describe their insects as 

 his species, differ from him in this respect, and give the number of 

 spots as variable, with which my specimens, as well as those of 

 Mr. Douglas and the Rev. T. A. Marshall, agree. ,
