CQLEOPTERA. 363 



second species of the same country in the splendid collection 

 of M. de la Cordaire. 

 We now come to species in which the tarsi, when viewed from 

 above, appear to consist of but four joints, the first of the usual five 

 being very short and concealed under the second(l). 



Sometimes the antennae insensibly enlarge towards the extremity, 

 or gradually terminate in a club; the intermediate joints, from the 

 third, are nearly in the form of a reversed cone; the two or four 

 penultimate joints form reversed triangles, and the last is ovoid. 



Thanasimus, Lat. Clei'us, Fab. 



The maxillary palpi filiform; last joint of those attached to the 

 labium large and securiform(2). 



Opilo, Lat. Notoxus, Fab. 



The four palpi terminated by a large securiform joint(3). 



Sometimes the three last joints of the antennae are much wider 

 than the preceding ones, suddenly forming a club, either simple and 

 in the form of a reversed triangle, or serrated. 



Those, in which this club is simple or not serrated, form two sub- 

 genera. 



Clerus, Geoff. TricJwdes, Fab. 



The maxillary palpi of these Cleri, properly so called, are termi- 

 nated by a compressed joint in the form of a reversed triangle; the 

 last of those that belong to the labium, which are larger than the 

 others, is securiform. The antennal club is hardly longer than wide, 

 and is composed of crowded joints; the third is longer than the se- 

 cond. The maxillae terminate in a projecting and fringed lobe. The 

 thorax is depressed anteriorly. 



These Insects are found on flowers; their larvse devour those of 

 certain Bees. 



Their stomach is widest anteriorly, and without plicae; their in- 

 testine is short, with two enlargements behind. According to M. 



(1) The Insects of this subdivision compose the genus Clairon, properly so 

 called, of Geoffroy; M. Dufour admits that the posterior tarsi consist of five joints, 

 the first of which is very short; the same joint is rudimental in the intermediate 

 tarsi, and wanting in the two that are anterior.
