458 SUBFAMILl STENINAE 



Stenus meyeri n. sp. (PL 14, fig. 7 — 8.) 



Black, only slightly shining, antennae, palpi and legs 

 yellow, antennae inluscate only at the tips, punctures 

 rough and dense, rugose; only tip of abdomen with very fine, 

 short hairs. 



Head broad, broader than elytra; eyes big, prominent; 

 frons deeply excavated, with deeply impressed slightly 

 convergent frontal furrows, roughly and deeply punctured 

 except at the base of insertion of antennae ; antennae 

 moderately slender, on the inside, except on the two basal 

 joints, provided with some long, thin hairs, 2nd joint slightly 

 longer than broad, 3rd joint slender, nearly three times as 

 long as broad, 4th about If as long as second, following joints 

 gradually decreasing in length ; the apical club-shaped joints 

 are all longer than broad ; palpi long and slender. 



Prothorax hardly longer than broad, its greatest width 

 before the middle, forwards strongly constricted, behind the 

 middle parallel, from there slightly concave, very densely and 

 deeply punctuj-ed ; punctures here and there confluent, 

 reminiscent of 1.9^ clavicornis Scop, from Middle Europe. 



Elytra at the suture nearly shorter than prothorax, not 

 convex, humeral angles distinctly set off, laterally slightly 

 rounded, backwards broadly emarginate. suture-line broadly 

 impressed, anterior margin with a faint border; punctures 

 rougher than on prothorax, equally rugose. 



Abdomen narrower than elytra and prothorax. tapering 

 towards the apex, laterally with a fine border, segments 

 without median carina, the first segments are constricted, 

 roughly and densely punctured, punctures towards posterior 

 margin becoming finer, generally of half the size of those of 

 the head; on the last tergites still finer, at the end of the fifth 

 segment a fine, whitish skinfold ; the dorsal slight emargi- 

 nation of the seventh segment carries a fine but distinct 

 granulation, but no comb-like teeth. 



Legs ro])ust, tarsi of half the length of tibiae, first joint 

 of the same length as the three following together, fourth 

 provided with long, narrow appendices. 



" The whole upper surface shows microsculpture, deepest on 

 tbe abdomen ; on the anterior parts some fine, engraved 

 striae are visible, especially on the head.
