BEETLES. 107 



aiitennre with larger or smaller processes on the inner 

 side in the male. The larva lives in the old wood of 

 willows. The beetle is very common on flowers. 



* M. marginelliis, Fabr. This species is also shining green, 

 with a yellow mouth. The tips of the wing-cases are orange. 

 The pronotum is broadly bordered with red. The joints of 

 the antenna?, from the third to the seventh, are excavated on 

 the inner side in the male, and the seventh is produced 

 at the apex into a blunt tooth. 



Genus Anthocomus, Erichs. 



Abdominal segments interrupted in the middle, and mem- 

 branous. Antennae eleven -jointed, filiform, rarely slightly 

 serrated or dentated. 



* A. fasciatus, Linn. Elytra black, with a broad red mark 

 on each before the middle, and a smaller band of the same 

 colour at the extremity. The extremities of the elytra are 

 reflexed in the male, with a small appendage. 



Genus Dasytes, Payk. 



Pronotum scarcely longer than broad, body clothed with 

 erect hair. The claws are simple in both sexes. The 

 antennre have eleven joints, and are situated on the sides 

 of the head in front of the eyes ; they are filiform and 

 generally dentated. The beetles live on flowering trees 

 and bushes. 



D. coeruleuSy Fabr. (Plate XL, Fig. 25). Wing-cases blue, 

 granulated. Antennae and tarsi black. Pronotum deeply and 

 sparsely punctured. The beetle is found in old branches of 

 oak and beech trees, where the larvae perhaps prey on 

 wood-boring beetles. It is common in many parts of the 

 Continent.
