Very narrowly elongate, very slightly Hattenecl above and 

 extremely glossy. The head is hollowed above, very smooth 

 and shining, and bears a slender median process directed 

 obliquely backward, hooked and slightly bifurcated at the end. 

 The labrum is rather strongl}- dilated in front and divided into 

 two roun(kxl lobes. The front margin of the head is gently 

 excised, the ocular canthus is blunt, not angular, and the 

 supraorbital ridge is rounded in front and behind. The 

 proiotum is almost unpunetured, deeply sulcate along the 

 middle, broadly margined in front, the margin deeper and 

 wider on each side, where there are a few fine punctures. The 

 front angles are rather blunt, the sides almost straight in front, 

 gently rounded behind. The lateral scars are reduced to a very 

 small rounded pit on each side. The elytra are very long, 

 deeply sulcate, with very convex intervals, the sulci containing 

 feebly impressed punctures, those of the dorsal sulci very 

 mmute, tlie lateral ones a little larger. The metasternuyn is 

 smooth, with a few very fine punctures at the sides bearhig 

 short hairs. The abdomen is very smooth. Tiie three lamellge 

 composing the club of the anteima are very long. 



Length, 23 mm. ; breadth, 8-5 mm. 



S. India : Anaimalai Hills, 3500 to 4000 ft. {H. L. Andretves, 

 June). 



Type in the British Museum. 



The tjipe is unique. This is a remarkal)le and isolated 

 species, the nearest allies of which arc found in Australia and 

 the Papuan Region.

Cylindrical, very convex, moderately elongate. The head 

 is very smooth and shining, but with some large deep ])unctures 

 on each side behintl. The lal)rum is dilated in front and very 

 gently excised at the front margin. The front margin of the 

 head is gently trisinuate, the su})raorbital ridges are almost 

 parallel, sharj), sharply angular in front, the median process 

 short, quadrate at the base, broadly longitudinally grooved,
