566 INSECTA. 



Dapsa, Zieg. 



Where the club of the antennae is narrow, elongated, and com- 

 posed of joints, laterally remote, the last of which is almost ovoid(l). 

 In the others the third joint is but little longer than that of the 

 preceding and following ones. 



Several species are indigenous to Europe, and live in the Ly- 

 coperdons, or under the bark of the Birch and some other trees. 



Endomychus, Web. Fab. 



Where the four palpi are thickest at the extremity; the three last 

 joints of the antenna arc separated laterally, are larger than the pre- 

 ceding ones, and compose a club in the form of a reversed triangle(2). 



Lycoperdina, Lat. — Endomychus^ Fab. 



Where the maxillary palpi are also filiform; the last joint of the 

 labials is larger than the preceding ones, and almost ovoid; the 

 fourth and following ones of the antennae, to the ninth inclusively, 

 are almost granose, and the two last in the form of a reversed tri- 

 angle(3). 



FAMILY 11. 

 APHIDIPHAGI. 



This family consists mostly of Insects which have an almost 

 hemispherical body, and a very short, transversal, and almost 

 lunate thorax. Their antennae terminate in a compressed and 

 obconical club, composed by the three last joints, and are 

 shorter than the thorax. The last joint of the maxillary palpi 

 is very large and securiform, and the penultimate joint of the 

 tarsi is profoundly bilobate. 



In the other Trimera of the same family, the joints of the

 should be referred to Dapsa.
