PHjEADOItETUS. PACHYRRHI3 ADORETUS. 285 



Leaden black in colour, with the antennae and legs deep red, 

 and clothed, not very closely, with short whitish setae, those upon 

 the elytra arranged in longitudinal lines. 



It is rather narrow in shape, with the elytra long and entirely 

 covering the pygidium. The head is rather narrow, and closely, 

 but rather coarsely rugose, with the clvpeal margin strongly 

 reflexecl and produced in the middle into two slight rounded lobes. 

 The pronotum is coarsely but rather closely, and at the sides con- 

 fluently, punctured ; its sides are obtusely angulated in the 

 middle, feebly serrated in front, with the front angles acutely 

 produced and the hind angles obtuse. The scutellum is strongly 

 punctured, and the elytra have the primary costae well marked, 

 rather narrow and strongly elevated, and the intervening spaces 

 broad and closely pitted. The pygidium bears short erect setae. 



Length, 11-13 mm.; breadth, 5-6*5 mm.

Adoretus seriesetosus, which inhabits the same region, bears a 

 remarkable resemblance to this insect, but the conformation of 

 the mouth is entirely different. 



Genus PACHYRRHINADORETUS. 



Pachyrrhinadoretus, Ohaus, Deutsche Ent. Zeits. 1912, p. 509. 

 TYPE, PacliyrrTiinadoretus rugipennis, Ohaus. 



Range. India. 



Oval, convex, rather smooth and shining, and thinly clothed 

 with fine hair. Eyes somewhat prominent. Clypeus rather small, 

 semicircular, with strongly rounded and reflexed margin. An- 

 tennae 10-jointed, the club not very long. Labrum rather large, 

 rectangular in front and produced in the middle into a blunt 

 rounded lobe (fig. 59 e), which is free in front and not produced 

 backwards. Mandibles large, meeting behind the median process of 

 the labrum, their apical lobes long and bluntly bidentate at the apex. 

 Maxilla deeply cleft at the extremity, with the outer lobe blunt 

 and truncated, and the inner one very sharp ; palpi stout, not 

 long. Mentum broad, transversely quadrate, with the anterior 

 part extremely short and its front margin nearly straight ; palpi 

 rather long. Legs stout, the front tibia rather feebly tridentate, 

 but the two upper teeth separated by a sharp notch ; claws very 

 long arid unequal, the longer one on the front and middle feet 

 very minutely cleft at the apex. 



d 1 . The abdomen is well arched and the pygidium exposed. 



. The upper surface is smoother, less punctured and less 

 pubescent than that of the male, the eyes are rather smaller and 

 less prominent, the abdomen very convex beneath and the pygi- 

 dium concealed by the elytra. The front tibia is shorter and its 

 teeth are much stronger and sharper. 



The club-shaped projecting rostrum or median lobe of the 

 labrum is very peculiar.
