7Ö ICHTHYURUS SUTURALIS. 



The liead sub-opaque, witli a large but indistinct heart- 

 shaped impression on the face above the antennae. The 

 pronotum very smooth and shining , covered with subtile 

 punctures, and with a row of deep punctures near the 

 anterior and posterior margin ; a somewhat quadrangular 

 impression before the middle of the hind margin , the im- 

 pression with a slightly raised and posteriorly grooved 

 carina in front. The elytra sub-opaque, closely covered 

 with large punctures as far as the front margin of the 

 pale yellow apical fascia', then without distinct punctures; 

 a slightly raised longitudinal line runs, not quite in the 

 middle , nearly parallel with the outer margin , and also an 

 oblique impression from the outer margin behind the shoulder 

 towards the inner margin a little before the apex without 

 however reaching it. The elytra very little narrowed towards 

 the apex which is broadly rounded, the sides nearly parallel, 

 the shoulders prominent. At the intermediate legs the 

 trochanters are sharply pointed at the apex within, the 

 femorae incrassated, slightly curved and armed beneath 

 with an acute tooth a little before the base, the tibiae 

 longer than the tarsi, nearly straight, the under surface 

 flattened, its margins irregularly serrated. The abdomen 

 slender , much narrowed towards the apex , each segment , 

 except the apical one, being narrower than the preceding 

 one ; the apical segment roof-shaped , about twice as long 

 as broad at its base, its sides straight , very little divergent; 

 the incision angular, almost reaching the centre of the 

 segment, its sides straight. 



Two males from Mount Ardjoeno , East Java (W. E. J. 

 Hekmeyer).
