Ru.st-recl or orange, with the head wholly or partly black ; 

 the pronotum with the extreme margins, a broad median stripe 

 and a patcli occupying the posterior angle, sometimes extending 

 to the anterior angle, and the elytra with the outer margins 

 rather narrowly and the sutural margins rather broadly black. 

 The legs and lower surface sometimes red and sometimes 

 wholly oi- i)aitly black. Rather convex and compa(;t in form 

 and moderately shining, excei)t the head and the sides of 

 pronotum and elytra. The jirosternum is only slightly elevated 

 behind and not compressed or produced. 



$. Elongate -oval. The head is densely rugosely punctured, 

 with the sides slightly prominent behind the eyes but less wide 

 there than in front. The 'pronotum is punctured rather spar- 

 ingly and finely in the middle and strongly and closely at the 

 sides. The lateral margin is gently rounded, the front angle 

 bluntly produced and the hind angle almost obsolete. The 

 elytra &vv smooth and shining near the suture, strongly and 

 closely punctured at the sides and apices, finely and not very 

 closely in the intervening region. The front tibia is feebly 

 toothed externally and its apex is broad and blunt. 



^. The upper surface is minutely and densely granular or 

 punctured and not very shining, except in the region of the 

 elj^tral suture. The head is convex and densely granular, with 

 the anterior part a little hollowed or vertical, the upper margin 

 semicircularly excised, the clypeal process tongue-like and 

 truncate. The anterior angles of the head are very obtuse, 

 the canthus reaches the middle of the eye and the sides are 

 bluntly ])rominent behind the eyes. The pronotum is minutely 

 and sparsely ])unctured in the middle and densely granular 

 at the sides. The lateral margins are curved in front, almost 

 straight behind, the front angles bluntly produced, the hind 

 angles obtuse. The elytra are closely aTid minutely punctured, 

 i-ather more strongly at the sides and very lightly near the 

 suture. The front tU)ia has very minute irregular lateral teeth 

 and the terminal fork is long and narrow. The middle and 

 hind tibiae are without distinct lateral spines, but the former 

 has a deej) excision of the inner edge just before the extremity 

 and the latter has a tooth at the same point. 



Variation oj the male. There is little variation in the normal 

 phase except in size. The mandibles are very short and of 

 simple form. They arc about as long as the head, feebly curved, 

 shar])ly ])ointed and dilated at the base internally. In the 

 Andaman Islands two representatives of a. different phase
