550 REVISION OF THE AMYCTERID^, 



stices costate; forceps short, laminye minute, fascicles widely 

 separated. Black, opaque; sulci with very minute sparse grey 

 scales, setae dark brown, fascicles red. 



Head large, strongly convex, minutely rugulose, forehead and 

 rostrum sparingly setigero-punctate. Rostrum short, thick, 

 excavate, external ridges prominent, internal short, basal grooves 

 and median notch well marked. Mandibles simple, inner 

 glabrous portion produced into a blunt point. Prothorax 

 (9x9 mm.) widely dilated in front of middle, narrowed to base 

 and apex, median lobe strongly produced, the whole having from 

 above a pentagonal appearance. Disc flat, feebly depressed in 

 centre, with a well defined median line and strongly marked 

 collar-constriction; finely and densely setigero-granulate, granules 

 rather fewer and coarser on sides and about collar-constriction. 

 Elytra oblong, subquadrate(16 x 9-5 mm.), not much wider than 

 prothorax, gradually widened from base to behind middle, strongly 

 declivous posteriorly; apex rather feebly mucronate, humeral 

 angles prominent, tuberculiform; disc with three broad sulciform 

 striae, transversely and shallowly rugose, with a row of minute 

 setae on either side: interstices four in number, prominent, costi- 

 form, strongly setigerous, first represented by a fine row of 

 granules, distinct onl}^ at base, the third running out into 

 shoulder. Sides with two rows of large punctures. M etas tern urn 

 flat, anterior prolongation truncate, feebly impressed. Fifth 

 ventral segment large, strongly excavate; excavation moderately 

 deep, not reaching anterior margin; preanal fossa deep, not 

 separated from rest of excavation; posterior edge slightly raised, 

 sinuous, with a fringe of short stout bristles on either side; 

 fascicles moderately far apart(3 mm.), situated within excavation. 

 Forceps short, apices rather thin, meeting in middle line, greatly 

 dilated at base, with an obtuse projection on inner edge; laminae 

 very small, situated behind projection on inner edge of forceps. 

 Legs long, slender; tibiae lightly sinuous; intermediate tarsi with 

 first joint somewhat dilated, inner side longer than outer, outer 

 edge sinuous; posterior tarsi with first joint strongly dilated on 

 inner side, outer edge almost straight.
