 smaller species, and with the antennae differino- in tlie shape of the 

 joints and in the darker club ; no carina at base of first dorsal

 Maxillary palpi with joint 1 very small; 2 long and slender, slightly ciirvedat 

 base, broader at apex ; 3 about as broad as long, obtusely angled on outer 

 margin ; 4 a little longer, dilated and obtusely angled on outer margin, at base 

 attenuate, and acuminate at apex. Prothorax a little longer than broad, slightly 

 longer than head, attenuate in front, rugosely punctured, longitudinally sulcate 

 in luiddle, the sulcus terminating in a fovea at a little before base, also a small 

 fovea on each side behind middle. Elytra nitid and bright red, nearly twice as 

 long as prothorax, and broader, attenuate at base, apex truncate, sides slightly 

 rounded to base, two basal foveae, dorsal stria extending a little beyond middle, 

 AVjdomen large, but shorter than the clj'tra, a little broader than the elytra 

 about middle ; first dorsal segment large, with sides broadly margined and two

 ters bearing at apex on the under-side a short spine ; femora incrassate in 

 middle ; anterior and intermediate tibiae curved, posterior pair straighter ;

Hah. : Sarawak, Quop, alt. 600 feet (14.iii.l4, found by beating 

 dead branches). 



Allied to P. heterocerus Raffr. from Java, but differs, among other 

 points, in colour and in the form of the antennae (see Raffray, Rev. 

 d'Eut., 1882, p. 16, plate II, fig. 16).
