374 INSECTA. 



penultimate joint of the tarsi, or at least of the four anterior ones, is moat 

 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 tirst joint elongated : the anterior ones are 

 frequently short and dilated. 



The type of this tribe is the genus 



l)n:< I.A. Fabricius. 



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, Hallomenus, Mefandrya, Hy/ntlus, &c. 



The fourth tribe, that of the (EDEMKRITES, 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 pre- 

 ceding tribe, and yet distinguished from them by their strongly inflated 

 posterior thighs, and their bicleft tarsial hooks, the (Edemerites present 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 some- 

 what 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 metamorphoses are unknown. 



These Heteromera will be comprised in a single genus, the 



OEDEMERA, Olivier, 



Where the posterior thighs are strongly inflated in one of the sexes, where 

 the aiiU-imn- are usually long and smaller at the extremity, and the elytra 

 suddenly narrowed near the end. 



There are several subgenera. 



The fifth and last tribe of the Stenelytra, that of the RHYNCHOSTOMA, is 

 composed of insects, some of which, such as the tirst, are evidently related by 

 the ensemble of their characters to the CEdemera;, while the others, in a 

 natural order, appear to belong to the family of the Rhynchophora. The 

 head is considerably prolonged anteriorly in the form of an elongated snout or 

 flattened proboscis, bearing the antenine at its base and tafore the eyes,
