 2'5 — 3"25 mm. ; van minor, 175 — 2 mm. (Plate IX. fig. 3. $.) 



This is another variable species, very closely resembling typical P. dubiosus in form. 

 The antennae are slender and rather long, the three-jointed club being also slender. 

 The thorax is covered with squamosity, and has sometimes three impressions, but the 

 two posterior ones may be obsolete. Its hind angles are a little prominent, and 

 rendered more distinct by bearing a spot of pale squamosity, which is more dense than 

 that of the general surface. The elytra appear to be always red, more or less spotted 

 with black, the black spots being free from squamosity. They are nearly evenly 

 convex in shape, the basal tubercles near the scutellum being absent or very ill- 

 developed, their basal margin is rather deeply and regularly emarginate, so that the 

 shoulders are produced and acute, and are free from the base of the thorax. The erect 

 setae are short and white, but rather conspicuous in fresh examples, especially at the 

 sides of the elytra. The puncturation is not very dense. All the femora are strongly 

 clavate. Beneath, the basal abdominal segment is strongly and distinctly punctured, 

 although towards the middle the punctures are more remote than at the sides. Very 

 small examples (var. minor) apparently referable to this species are not infrequent, but 

 there appears to be no good character to separate them, unless the more obsolete 

 puncturation of the base of the abdomen beneath should prove constant.

Rufo-piceus, sat latus, elytris rufescentibus, nigro-maculatis. Antennae totae rufae, 

 sat elongatae, sed crassiusculae, clava distincte 3-articulata. Pronotum aureo-squamosum,

This species has very much the form and general appearance of large typical 

 examples oi P. eidepis. In the two examples taken the anterior thoracic impression is 

 large and distinct, the others are obsolete. The hind angles are distinct, and appear to 

 be marked by spots of denser squamosity than that of the rest of the thorax. The 

 elytra are nearly evenly convex, there being little or no trace of the tubercles at the 

 base near the scutellum, but they are a little flattened transversely behind their basal 

 margin. The humeral angles are acute and formed like those of P. culcpis. From 

 that species P. neglectus is at once distinct by the thicker antennae, the intermediate
