BYUHIIIDAE. 317 



Tibiae with slender greyish setae, the anterior nearly straight, grooved 

 along the outer face, the intermediate more strongly curved than the pos- 

 terior ; tarsi with well-developed membranous appendages. 



Antennae finely pubescent, 2nd joint half the length of the 1st, narrowed 

 apically, the next slender and almost equalling the following three together, 

 joints 7 10 successively dilated and subquadrate, the terminal elongate- 

 conical and acuminate, that of the other antenna quite obtuse. 



Underside nigrescent, finely setose, the last abdominal segment rufes- 

 cent and densely clothed. Metasternum ample, distinctly but not closelv 

 punctate ; hind coxal laminae very closely and finely punctured. 



The minute, slightly raised scutellum, subtruncate thoracic base, slender 

 yet quite discernible scattered setae, and different form differentiate this 

 from P. creperus, 2792. 



Length, 4.1 mm. ; breadth, 2| mm.

 p. 265. 



Subovate, broadest near hind thighs, moderately convex, somewhat 

 nitid ; head and thorax reddish-chestnut, elytra rather paler, legs fusco- 

 testaceous ; sparingly covered with distinct, decumbent, rather short 

 yellowish hairs, and with longer erect ones along the sides, the base of elytra 

 thickly ciliate with elongate pubescence. 



Head coarsely and moderately closely punctured except at its extreme 

 base, forehead broadly rounded, with well-developed refiexed margins. 

 Eyes only slightly convex, hyaline. Thorax almost twice as broad as long, 

 its sides finely margined, nearly straight and only slightly narrowed behind 

 the middle, gently curvedly narrowed towards the acute and prominent 

 anterior angles, posterior angles obtuse ; base widely bisinuate, rounded in 

 the middle, apex subtruncate ; its surface very distinctly and moderately 

 closely punctate, sometimes with a smooth linear space along the middle. 

 Scutellum punctate, cordate or suboblong. Elytra thrice the length of 

 thorax, as wide as it is at the base, their apices widely rounded outwardly, 

 much less so near the suture ; each elytron with 9 fine striae, the outer 

 ones less distinct, the intermediate obsolete near the base ; interstices 

 plane, their punctation distinct, yet rather finer than that of the thorax. 

 Pygidium broad, with distant, indistinct subgranular sculpture. 



Underside more or less finely punctured, fusco-testaceous, abdomen a 

 little shining and often fuscous ; the sternum with numerous elongate, 

 slender fulvescent setae, those on the femora erect. 



Male. — Antennae rather short, basal joint moderately elongate, some- 

 what bent, gradually incrassate, oblique at extremity ; 2nd nearly as thick 

 as the 1st but only half its length ; 3rd rather slender ; 4th stouter and 

 longer, angularly produced, sometimes acutely dentiform medially in front ; 

 club minutely and densely pubescent, composed of 4 nearly equal leaflets. 



Fern. — 4th antennal joint simple, 5th very short, but more or less 

 prolonged in front ; club triarticulate. 



In the rather larger, much paler, and rather more glossy 0. nitidnla, 

 3233, the posterior angles of the thorax are more rectangular, but the 

 anterior are less acute ; the sutural striae only are well marked, and the 

 antennae also differ.
