24. KLEDITOMA HALOPHILA. 

 PL XI, fig. 3. 



KledUoma halophila, Thoms., Oef., 1861, 398. 



Black, shining ; the apex of femora, the tibiae and tarsi piceous ; wings 

 hyaline, the nervures black. Antennas with the third joint double the 

 length of the fourth ; the 7-jointed club abrupt ; scutellum finely longi- 

 tudinally striolated. Abdomen scarcely so long as the thorax ; the hair- 

 fringe moderately dense. 



The < has the antennae longer than the body ; the third joint is 

 more than double the length of the fourth, thickened, and sharply 

 incised. 



Length li mm. 



The seven-jointed club separates this species from 

 subaptera. 



Found at Polperro, in Cornwall, by the Rev. T. A. 

 Marshall, among decaying seaweeds. 



Sub-family ALLOTRINA. 



Second segment of abdomen longer than all the others united* Body 

 smooth, shining, not punctured or striated ; scutellum rounded, shining, 

 impunctate, without any depression on the top. Antennae 13-jointed 

 in ? , 14-jointed in <^, the latter with joints 3 5 sinuated. Cubital 

 nervure issuing from near the middle of the basal; areolet situated 

 considerably beyond the apex of the second abscissa of the costal 

 nervure, i. e. at some distance from the base of the radial cellule. Hind 

 tibiae with one spur. 



The radial cellule may be open or closed ; and it 

 may be open also at the apex, through the radial ner- 

 vure not reaching to the costa ; the areolet is usually 

 indistinct, and is seldom completely closed on the lower 

 side. In a few species the wings are abbreviated. The 

 antennae in the ? are longer than the thorax or even 

 longer than the body, and are usually thickened gradu- 

 ally towards the apex ; they are much longer and 

 thinner in the $ , besides having the basal three joints 

 of flagellum sinuated. The joints of scape are thicker 

 and more ovoid than those of the flagellum. The 

 mesonotum has sometimes the parapsidal furrows indi- 

 cated to a more or less extent ; there may be also a
