 and pointed earlets.*

Which are distinguished but little from the preceding sub- 

 genus, except by their tongue, which is entirely corneous, 

 rounded at the superior end, and without distinct di- 

 visions. The species are all exotic. f 



The others, and which with those that immediately follow, 

 appear to approximate m_uch to the brachini, have the penul- 

 timate articulation of all the tarsi deeply bilobate ; the man- 

 dibles and jaws long, narrow, and advanced ; the body suffi- 

 ciently thick, with the head in the form of a narrow and elon- 

 gated triangle, and the corslet almost cylindrical, a little 

 narrowed posteriorly.! 



The first articulation of the antennae is very long, and 

 narrowed at its base. The mentum is almost in the form of 

 a crescent, without tooth in the centre of its emargination. 

 The tongue is prominent, narrow, almost linear, and termi- 

 nating with three spines, and accompanied by two paraglossae. 

 The under part of the tarsi is furnished with down. Such 

 are the characters of

An unpublished helluo of Brazil ought, it appears to me, to form a new 

 sub genus, in consequence of its filiform palpi, and of which the last arti- 

 culation is cylindrical. 



J The dryptae have also relations with cychrus, and appear to connect 

 the cicindeletae with the section of grandipalpous carabici. Many sections 

 of this family seem to be attached, like so many branches, to the cicin- 

 delae. Most part of the other families of insects are in the same predica- 

 ment, or form ramified trunks. In a word, continued series do not exist 

 in nature.
