ORDER COLEOPTERA. 5.57 



Some species have, as well as the Opatrini, the legs nar- 

 row, elongated, hut little dilated at their extremity, and 

 almost always identical in the two sexes ; the corslet narrowed 

 abruptly on each side, near the posterior angles, which form 

 a sharp tooth. These are Dendari, properly so called.* 



In the following the four anterior legs, or at least the first 

 two, are dilated triangularly at their extremity. The under 

 part of the intermediate and the last two, and that even of 

 the two posterior thighs, is silky in many males. 



Sometimes the sides of the corslet are narrowed abruptly 

 near the posterior angles, or are almost rounded, with a pro- 

 jecting tooth at this extremity. The body is oval. Such are 

 Heliophilus of M. le Comte Dejean. Sometimes the cors- 

 let terminates insensibly on. each side, in a pointed angle. 

 The body is proportionally shorter and broader. 



Some species, with a large corslet, but little broader than 

 long, strongly edged laterally, and whose body is but little 

 gibbous above, compose the genus Eurynotus of Mr. 

 Kirby.-|- 



Others, whose body is sensibly more convex or more gib- 

 bous above, with the corslet transverse, and very slightly 

 edged, are Isocerus, Meg. Dej. 



In the males of the last pedini, the first three articulations 

 of the two anterior tarsi, always very much dilated, diminish 

 progressively in breadth, and the fourth is very small. The 

 posterior thighs of the same individuals are concave and silky 

 underneath, as are likewise those of the HeliophUi. The 

 body is oval, with the corslet but slightly edged out, widen- 

 ing from front to rear, or but slightly narrowed behind,
