58 Laseola erythropus Sim., with a Key to British Laseolae. 
others which have been described under the names of jucunda, 
Camb., proximo. Camb., and dissimilis Camb., (§ non <$) being 
referable respectively to prona Menge, erythropus Sim , and 
inornata Cambr. This confusion of synonomy and identity 
has been no doubt, caused by their general great rarity, for 
only one species seems to be at all frequent, viz., L. inornata 
Camb., which has been found in a few localities in the south, 
Dorset, Newhaven, Eastbourne, and Essex ; I have taken it in 
the Isle of Man, and there is an old unlocalised record for Ire- 
land. The distribution of erythropus Sim., has already been 
given. L. prona Menge and dissimilis Camb (one male only, 
the type) have occurred in Dorset ; L. tristis Hahn, in Wales, 
and at Bloxworth Heath and Killarney ; L. coracina C. L. Koch, 
Bloxworth and Suffolk, (one (J). 
Taking their general coloration as a basis, the Laseolae 
may, for the purposes of identification, be divided into two 
groups, the darker forms L. tristis Hahn and coracina C. L. 
Koch in one, and the lighter forms, the remainder, in the second. 
Attention should then be given to the size and relative position 
of the eyes and the curve or otherwise of the posterior row, 
but the surest means of discriminating the various species is 
afforded by the shape of the ocular prominence and the genit- 
alia characteristic of each of them, and reference to the figures 
of these parts in the plate will render it easy to determine 
the identity of any species under examination. Some of the 
Laseolae are found on bushes or the lower branches of trees, 
and others beneath stones and pieces of rock.
