Mr. I). Shar])'s Contributiuns to the 



tinctly constricted; the surface coarsely and extremely 

 densely punctured ; the interstices very small, so that the 

 sculpture is deeply rugose. Elytra slightly longer than 

 the thorax, with the humeral angles prominent and well 

 marked, coarsely, deeply, very closely punctured, scarcely 

 at all sliining. Hind body narrowed towards the extre- 

 mity; all the segments finely margined, the three or four 

 basal ones finely carinate at the base in the middle; the 

 basal segment rather closely and distinctly, the apical ones 

 finely and obsoletely, punctured. Legs unicolorous yellow, 

 very slender, rather long ; hind tarsi elongate and slender, 

 clear yellow ; 4th joint slender and simple. 



Ega ; a single female. 



Obs. — This species is about the size of ^S*. incanus, but 

 is a little more elongate in proportion to the -width, the 

 antennaj and legs are longer and more slender ; the elon- 

 gate basal joint of the front and other tarsi separate it 

 abru})tly from that species and its allies. 



10. Stenus Traili, n. sp. (Sect. I. A, Er.) Niger, 

 opacus, dense punctatus, antennarum basi, palpis, pedi- 

 busque testaceis, fronte leviter depressa, fere plana ; an- 

 tennis distincte clavatis. Long. corp. fere 1 i lin. 



AntennfB moderately long, rather slender ; joints 8 — G 

 yellowish, the others nearly black; 1st and 2nd joints 

 stout, 3 — 6 slender and elongate, each a little shorter 

 than its predecessor; 7th joint much broader than 6th, 81 h 

 smaller than the contiguoiis ones, Dtli and 10th stout, but 

 each longer than broad ; 1 1th joint small, shorter than 1 Otli. 

 Palpi only moderately long, quite yellow. Head almost 

 as broad as the elytra; the space between the eyes rather 

 depressed, but almost even, very obsoletely bisulcate, 

 evenly and densely punctured. Thorax rather longer than 

 ljr(xxd, a good deal narrower than the elyti-a ; the sides 

 much rounded in front of the middle, and a good deal 

 constricted behind ; it is densely and rugosely punctured 

 and not shining. Elytra a little longer than the thorax, 

 densely and coarsely punctured, quite dull. Hind body 

 finely but distinctly margined, much acuminate, closely 

 punctured; the ])unctures moderately coarse on the basal 

 segments, (|uitc fine on the pemiltimate one, 2—4 each 

 with a well-marked carina on the middle of the basal part, 

 and a nuich shorter one on each side. Legs yellow; tarsi 

 long and slender, the basal joint of the hind one as long 

 as the three following joints together.
