Group FliOTAXINI. 



Head short, rather broad, not narrowed posteriorly ; antennte 

 inserted wide apart and as close to base of mandibles as in tbe 

 majority of Py-ioiu'ute ; eyes at a short distance behind antenna^ 

 emarginate, rather finely facetted ; gula with distinct meiitigerous 

 process. Antennje shorter than body in both sexes. Prothorax 

 rouuded at sides, broader ia front than at base, almost flat above, 

 lateral edges somewhat sharp but not marginate. Mesonotum 

 with undivided stridulatory area. Tibiae carinate along each side, 

 spread out at apex. Frout coxae transverse, somewhat prominent, 

 their acetabula open posteriorly. Acetabula of middle coxae extended 

 to epimera. Wings with veins Cu. 1 bifurcate, Cli. 2 absent. 



This group is formed for the reception of a single remarkable 

 genus which cannot well be included in any of the groups estab- 

 lished by Lacordaire. In some points of structure, this genus 

 shows an affinity with the Lepturina', but in the shape of the head 

 and prothorax it resembles no member of that subfamily. From 

 the forward position of the autennte, it appears to be a primitive 

 form, although in certain other respects it is more specialized 

 than the genera included in the next group.
