400 INSECTA. 



The body is almost cylindrical in some, and oval in others; the head 

 is inclined, and the thorax trapezoidal. The anterior extremity of 

 the head does not project, and the posterior thighs not inflated, 

 characters which distinguish these Insects from various Heteromera 

 of the ensuing tribe. The penultimate joint of the tarsi, or at least 

 of the four anterior ones, is most commonly bilobate, and in those 

 where it is entire, the posterior legs at least are fitted for leaping; 

 in this case they are long and compressed, the tarsi small, almost 

 setaceous, and their first joint elongated; the anterior ones are fre- 

 quently short and dilated. 



The type of this tribe is the genus 



DiRC^A, Fab. 



In Dircsea properly so called, the maxillary palpi are not serrated, and their 

 last joint projects more on the inner side than the preceding ones. The 

 thorax is insensibly lowered on the side. The scutellum is very small. 

 Here we have Orchesia, Halhmenus, Melandrya, Hypulus, &c. 



The fourth tribe, that of the CEdemeeites, is connected with the 

 third by several characters, such as having the antennse inserted 

 near the eyes, and their origin exposed, the mandibles bifid at the 

 end, the penultimate joint of the tarsi bilobate, and the maxillary 

 palpi terminated by a larger and securiform joint; but if we except 

 the Nothi, approximated by the form and breadth of the thorax, and 

 by some other characters to certain Heteromera of the preceding 

 tribe, and yet distinguished from them by their strongly inflated 

 posterior thighs, and their bicleft tarsial hooks, the CEdemerites pre- 

 sent a union of characters which will not allow us to confound them 

 with the other Heteromera. The body is elongated, narrow, almost 

 linear, and the head and thorax are somewhat narrower than the 

 abdomen. The antennae are longer than the two latter, serrated in 

 some — Calopus — filiform or setaceous, and composed of long and 

 almost cylindrical joints in the others; the anterior extremity of the 

 head is more or less prolonged into a little snout, and somewhat 

 narrowed behind; the eyes are proportionally more elevated than 

 in the preceding Heteromera. The thorax is at least as long as it 

 is broad, almost square, or nearly cylindrical, and slightly narrowed 

 behind; the elytra are linear or subulate posteriorly, and frequently 

 flexible. These Insects are found on flowers or trees. Their me- 

 tamorphoses are unknown.
