(6'5 mm.) "svith slightly longer thorax, longer and more sharply 

 pointed spines at the apex of the elytra, which are more deeply 

 striated, the femora also are distinctly clavate. In fresh examples the 

 extreme apices of the femora and tibise are often tipped with black. It 

 seems probable that this beautiful insect has been carried down by the 

 Eoyal Canal from one of the Westmeath Lakes, as has almost certainly 

 been done in the case of Corixa Bonsdorffi and other aquatic animals. 

 The colouring of H. appendicxdata renders its detection very difficult, 

 as it closely resembles the water-plants to which it clings. Eeitter 

 records this species from central Eui'ope, and it is also included in 

 the Scandinayian list, Siberia (Heyden). In England it has only been 

 recorded from a few localities in the east.

Eecorded as L. puncUcoIUs in these references, but the specimens 

 cannot be traced. L. septentrionis, Weise, may have been mistaken 

 for this species.

!Not uncommon in meadows, but rather local. Mr. C. W. Buckle 

 obtained it plentifully on young shoots of oats, in company with its 

 larva, in the month of July. There are two varieties of this insect 

 found in Britain — one with the thorax pitchy black fouud only in 

 Ireland ; the other with metallic green thorax, and relatively broader 

 elytra, found in the south of England (see '97 Ch. 1). Abroad this 

 species has been recorded fi'om Berlin and central Sweden. In some 

 of the earlier references this insect has been recorded as L. Erichsoni, 

 Suffr.
