CYCLOMMATUS SQUAMOSUS. 47 



The elytra are subshining and covered with very distinct 

 punctures ; the interspaces are very minutely sculptured 

 except along the suture. Between the shoulders and the 

 scutellum a very distinct transverse impression is present. 



Under surface and legs densely covered with small roun- 

 dish yellowish scales, on the sides of the head and of the 

 metasternura , however , the scales are elongate. The pro- 

 sternal process is eonically porrected. The fore-tibiae are 

 slightly curved and armed on the outside, a little beyond 

 the middle, with a small spine. 



As is already said this specimen originates from Brunei 

 (Borneo) and makes part of the collection of Mr. Neervoort 

 van de Poll. 



Length of the forma minor (without mandibles) 20 

 mm , that of the mandibles 8 mm. ; breadth at the shoul- 

 ders of the elytra 7 mm., length of the elytra ll^ mm. — 

 In this specimen, which has a narrow shape, the scales 

 are larger than in the forma major, especially on the head 

 and pronotum , and they are less numerous on the under 

 surface ; the coloration is somewhat darker , the tarsi and 

 antennae nearly black, the metallic hue on the pronotum 

 and elytra somewhat coppery. 



The mandibles, which are as long as the head and 

 thorax taken together, are broad, not narrowed towards 

 the tip, and enlarged at the base on the inner margin; 

 these enlarged portions are narrowly and deeply notched, 

 so as to form two cylindrical teeth on each mandible; 

 between these basal teeth and the broad obliquely truncate 

 ante-apical ones the inner margin is faintly undulate; the 

 space between the ante-apical tooth and the tip is occu- 

 pied by five distinct teeth. 



The head is less distinctly impressed and its front por- 

 tion more rapidly sloping to the clypeus; the front mar- 

 gin of the latter is regularly convex , and not turned upwards. 



The groove which accompanies the front margin of the 

 pronotum is less distinct and more widely interrupted in
