truncated in front, leaving the mouth parts exposed, and 

 without grooves for the antennae. They are found on bushes, 

 and the larva3 under the bark of trees. 



* C. linearis, Linn. (Plate XL, Fig. 9). The elytra are 

 vellow in the male, frequently with a black suture, rarely quite 

 black. In the female they are black, margined with yellow, 

 rarely entirely yellow. The front part of the head and the 

 pronotum are red, the latter frequently with a black spot in the 

 middle. Length, 10 mm. It is found under the bark of oak 

 and alder, in which the larva also lives. It is not uncommon. 



Family XXVIL DASOILLID-ffl. 



Elytra covering the abdomen. Antennae eleven -jointed, 

 filiform, or dentated. Prosternum without a projection towards 

 the mesosternum. Tarsi five-jointed, with the last joint but 

 one bilobate or simple, in which case the antennae are situated 

 nearer the front of the head. They are found on flowers. 

 The larvae live on the roots of plants. 



Genus Dascillus, Latr. (Atopa, Payk). 



Body elongated and cylindrical. The first three tarsal joints 

 are lobate. Antenna filiform, with the second joint very 

 short. Head bent forward, much narrower than the pronotum, 

 which is twice as broad as long, somewhat narrowed in front, 

 and with two slight concavities behind. 



* D. cervinus, Linn. {cinereuSj Fabr, 3"), (Plate XL, Fig. 10). 

 This is the only British species. It is black, clothed with very 

 thick and fine grey pubescence, and has either only the claws 

 and apex of the abdomen yellowish-brown, or the antennae, 

 legs, and elytra also. It is most frequently met with in chalky 

 districts, where it lives on flowers and flowering shrubs.
