NEW BRITISH SPECIES, ETC., IN 1870. 35 



and having finer and less numerous punctures in the two 

 dorsal longitudinal striae. A third example in my collection 

 has the thoracic punctuation of tricolor ; so that Mulsant's 

 original reference of distans as a variety to that species may 

 be correct. X. distans somewhat resembles very light spe- 

 cimens of X. linearis, as Dr. Kraatz remarks; indeed, the 

 specimen above mentioned to have been named by him has 

 been also named linearis for me by M. Fauvel. It seems, 

 however, to differ structurally from that species.

 Rather larger, and especially broader than S. angustatus, 

 with the elytra comparatively slightly shorter, and their 

 punctuation and that of the underside of the head rather 

 stronger; the head also is shorter and wider. This insect is 

 apparently equally common with S. angustatus ; and is one 

 of those species that are most readily separable by a super- 

 ficial examination. 



26. Stenus OSCILLATOR, Rye, I. c, vol. vii, p. 7 (described). 

 A single specimen, taken by Dr. Power at Holme Bush, 



Sussex, on 19th April, 1863, appears as it were intermediate 

 between S. paganus and S. latifrons, having the palpi and 

 antennas coloured as in the former, and being of the size and 

 build and having the dark legs of the latter. It differs from 

 both of those species, however, in its less strong and not 

 quite so close punctuation, more shining appearance, more 

 decided frontal elevation, and in its thorax being somewhat 

 less suddenly and more slightly contracted behind. Its an- 

 tennce, also, seem thinner and longer than those of latifrons^
