LE CONTE.— LONGICORN COLEOPTERA 



We may now proceed to divide the LepturidcB according to the following scheme 

 commencing with those most nearly related to the central group Cerambycidce, and 

 proceeding upwards to the most isolated form Leptura. 



A. Frons declivis, oculi intus valde emarginati, antennae inter oculos sitae. 



1. Caput postice constrictum, oculi transversi, elytra abbreviata. 



2. Caput postice constrictum, antennse filiformes. 



3. Caput postice non constrictum, antennse nodosse.

6. Oculi antice emarginati, transversi, tibise calcaribus terminalibus. aegaleus.* 



7. Oculi antice emarginati, vix transversi, tibioe calcaribus ante apicem sitis, palpis 



apice rotundatim truncatis. toxotus.

11. Oculi vix emarginati, palpi oblique truncati, mesosternum parallelum. evodinus. 



C. Frons plana, oculi valde emarginati, antennae inter oculos sitae. 



12. Caput postice subangustatum, palpi labiales latiorss. 



13. Caput pone oculos valde constrictum, palpi labiales non latiores, thorax angulis 

 posticis productis, antennae articulis non impressis. 



14. Thorax angulis posticis productis, antennae articulis 5-11 impressis. 



15. Thorax angulis posticis non productis, antennse articulis non impressis.

TYPOCERUS 



LEPTURA 



Subdivision I. LEPTUEIDJl. 



Group 1. 



This group is distinguished by a short head and deflexed front ; the antennae are 

 situated between the eyes, which are emarginate : the body is linear, not narrowed 

 posteriorly : it approaches the genuine Ceramhjcidce, and likewise the Lamiaria, from 

 the latter it is distinguished by the simple anterior tibiae, from the former by the 

 conical anterior coxae. The palpi are cylindrical, not dilated. 



* Rhamnusium has the same characters, but is distinguished by haying the mouth not prolonged, and the 

 antenna shorter than the body and serrate.
