excavated between the eyes, and without any smooth ridges, in 

 having the thorax more bulged out on the sides, and with an 

 olive gloss both on it and the elytra. The legs are black, with 

 the exception of the upper part of the thighs which are yellow.

 Only differs from the last in being much smaller, in having 

 the head less excavated between the eyes, in having the thorax 

 more thinly punctured, and in wanting the olive gloss on both 

 thorax and elytra.

Length 2 lines. 

 Black, opaque. Head smooth between the eyes. Thorax 

 without punctui-ation in the middle, but with transverse looking 

 punctures towards the apex and base, which are both rather con- 

 stricted. Elytra strongly punctured, and of a brassy green colour 

 with a ruddy hue in the middle. 



251. — Stenus cupkeipennis. n. sp. 



Length 2^ lines. 

 Head and thorax lightly punctured, the former with a greenish 

 the latter with a bluish gloss. Elytra punctured and of a brilliant 

 coppery red. Abdomen bluish black, nitid. Basal half of the 

 thighs yellow, the i-est brown. Fourth joint of the palpi not 

 bilobed. 



252. — Stenus pdncticollis. n. sp. 



Length 2 lines. 

 This species also has the elytra of a coppery red, but of a 

 redder and less brilliant character than in the last described 

 insect. The head and thorax are closely and evenly punctured 

 all over, in this respect differing much from both the preceding 

 species. Li other respects it exactly resembles S. viridiceneus.
