left supra-orbital ridge. Anterior angles of head containing about 120°, canthus 

 rounded externally ; supra-orbital ridge as in Trapezochilus dorsalis ; parietal ridges 

 directed slightly forwards. Prothorax and mesothorax much as in Trapezochilus 

 dorsalis, but with the median groove of the pronotum often more distinct, and a pair 

 of distinct large oval scars on the mesosternum. Metastermim with lateral areas very 

 broad throughout, almost as broad in front as behind, but not in contact with central 

 area ; central area unpunctured ; lateral areas finely punctured and hairy ; anterior 

 intermediate areas hairy and a little more coarsely punctured in anterior angles, 

 smooth behind ; posterior intermediate areas very coarsely but often sparsely punc- 

 tured, not hairy. Hind coxae usually smooth. Second abdominal sternum usually 

 punctured In front of scars; abdominal sterna otherwise smooth. Elytra with grooves 

 5-7 more or less broad, their flattened polished surface usually more or less completely 

 bordered on either side by a roughened line, with which the punctures are often con- 

 fluent, the punctures coarse and as a rule distinctly transverse.

I have also seen one specimen from the island of Madura which is the property 

 of Mr. H. E. Andrewes; specimens from Sumatra, Tjibodas c. 5000 ft., Tengger 

 Mountain, and Soekaboemi in the Berlin collections; and specimens from Preanger 

 4-6000 ft., Buitenzorg, and East Java as well as Wiedemann's types in the Hamburg 

 collection. 



Description. — Length 45-56 mm. Differs from the preceding in the following 

 characters only : upper tooth on both sides often more obtuse, the mandibles less 

 (often not at all) convex above behind it ; surface of head less rugose ; parietal ridges 

 usually extending somewhat more directly outwards; all but one or two of the punc- 

 tures of posterior intermediate areas of metasternum usually confluent and concen- 

 trated along the inner margin of this area ; posterior part of hind coxae more or less 

 strongly punctured; grooves 5-7 and posterior part of groove 8 of elytra very broad, 

 each with roughened margins and a flat polished surface marked by a single row of 

 punctures.

Description. — Length 26-5 mm. Lahrum hairy and punctured, anterior margin 

 with a deep semi-circular excavation, angles rounded and prominent, sides straight 

 and parallel. Antennal lamellae long, six in number. Left mandible somewhat larger 

 than right; upper tooth small on both mandibles, rectangular on left, more obtuse 

 on right ; two upper terminal teeth partly fused, lower one distinct, meeting them in 

 an angle of about 60° ; anterior lower tooth rudimentary on left, large but blunt on
