A NEW SPECIES OF CIS. 

 BY THEODORE WOOD. 



I have much pleasure in recording the capture of this most 

 singular insect, which, as it appears to be unknown on the Continent, 

 I venture to describe as new to science. I have met with it upon 

 three occasions during the present year. Firstly, a single J" speci- 

 men beneath the bark of a decaying pine-tree, on January 23rd; 

 secondly, September 15th, in the utmost profusion, from boleti upon 

 a decaying birch ; and, thirdly, September 23rd, a single c? from a 

 large fleshy fungus upon an ash-tree, a mile and a half from the scene 

 of the former captures. All three localities are at West Wickham, 

 and it is astonishing that so conspicuous an insect should have been 

 passed over for so long, more especially in a district which has been 

 worked by some of our best collectors. 



As will be seen from the description, the male insect can be 

 at once distinguished from any of our British species, and would 

 appear to be most closely allied to Cls quadridens, Mellie, from 

 which, however, it is abundantly distinct. The female, being without 

 the lamellae upon the clypeus and the thorax, is less conspicuous, but, 

 when fully mature, could hardly be confounded with any other species. 

 I have taken the insect in all stages of its development, and find that 

 in the ^J pupa the lamellae are fully as noticeable as in the imago. 



I append a description, which, with his usual kindness, the Eev. 

 W. W. Fowler has drawn up for me.
