362 INSECTA. 



The only species known Trichodes cyaneus, Fab. inhabits 

 the Isle of France. 



Tillus, Oliv., Fab.(l) 



Mandibles moderate, cleft or bidentated at the extremity; antennae 

 sometimes serrated from the fourth joint to the tenth inclusively, 

 with the last ovoid, and at others suddenly terminating, from the 

 sixth, in a serrated club. The last joint of the labial palpi is very 

 large and securiform; head short and rounded; third and fourth 

 joints of the tarsi dilated in the form of a reversed triangle. Found 

 in old wood or on trunks of trees. 



In the remaining Insects of this tribe, which are always distinctly 

 pentamerous, the four palpi terminate in a club; the last joint of the 

 labials is almost always securiform. 



Here, the four first joints of the tarsi are provided underneath 

 with membranous pellets, projecting in the form of lobes. The 

 thorax is elongated and almost cylindrical. 



Priocera, Kirb. 



The body convex; thorax narrowed posteriorly; last joint of the 

 maxillary palpi less dilated than that of the labials and in the form 

 of a reversed and oblong triangle; the labrum emarginated. 



But a single species is known, the Priocera variegata, Kirb., 

 Lin. Trans. XII, p. 389, 390, xxi, 7. 



Axina, Kirb. 



The body depressed; last joint of the four palpi very large and 

 securiform. 



But a single species has yet been described, the Axina analis, 

 Kirb., lb., fig. 6. From Brazil. 

 There, the penultimate joint of the tarsi is alone distinctly bilo- 

 bate. The thorax is square. The body is depressed as in Axina, 

 and the palpi terminate as in the same subgenus. Such is 



Eurypus, Kirb. 

 E. rubens, Kirb., lb., 5, also from Brazil. I have seen a 



(1) Tillus elongatus, Oliv., Col. 11,22, 1, 1; Chrysomela elongata, L. ; Clerus 

 unifasciatus, Fab.; Oliv., IV, 76, ii, 21. The antennce of the first are serrated from 

 the fourth joint, and the thorax is cylindrical. In the second, the antennae from 

 the sixth joint terminate in a serrated club. The thorax is narrowed posteriorly. 

 The last joint of the maxillary palpi is longer, in proportion, than that of the first 

 species, and is compressed.
