2 CYCLOMMATUS FREY-GESSNERL 



these scales are roundish ou the head and pronotum, 

 narrow ou the elytra. 



The mandibles are as long as the distance between the 

 front-margin of the head in front of the eyes and the base 

 of the abdomen ; their outer margin is regularly convex 

 from the base to the apex, their inner margin armed at one 

 G^li of their length with a strong tooth ; the ante-apical tooth 

 is not truncated , and between it and the tip of the mandible 

 three teeth are present. On the apical third of the mandibles 

 the outer upper margin rises slowly, but opposite the front- 

 margin of the ante-apical tooth this raised margin ends 

 suddenly so as to form here a small tooth-like projection. 

 The mandibles are opaque and covered with scale-bearing 

 punctures which disappear, however, towards the end where 

 the mandibles are glossy. 



The upper side of the head shows a large flattened depres- 

 sion, the margins of which are only raised in front of the 

 eyes; the sculpture on the cheeks is slightly coarser than 

 that on the disk. The front-margin of the head between 

 the outer margin of the mandibles is broadly emarginate, 

 the middle portion of the emargination nearly straight; at 

 this margin the head sinks perpendicularly down towards 

 the clypeus which is declivous and broadly truncate and 

 has its front-margin faintly or more distinctly ^) bisinuate. 

 The sides of the prothorax are angular about the middle ; 

 the front-margin is accompanied laterally by an indistinct 

 impression , and the surface is densely covered with a scale- 

 bearing punctuation ; a faintly impressed line runs along 

 the middle of the pronotum. 



The elytra are covered with a fine but very distinct 

 scale-bearing punctuation , and each of them shows two 

 indistinct costae. 



The intercoxal parb of the prosternum is conically por- 

 rected. The fore-tibiae are unarmed and nearly straight. 

 Two male specimens of equal development and both from
