278 OETHOPTERA. 



arcuated line. The femora and the intermediate tibiae are so much compressed as to 

 be nearly lamellar ; the posterior femora are not clubbed at the base. The genicular 

 lobes of the anterior and posterior tibiae are sometimes produced. The elytra are 

 elongated : in the females rough and irregularly reticulated ; in the males produced 

 into a long apical field, and with a rhomboidal speculum, which is narrower and more 

 elongate than in Apithes and Orocharis. The males are sometimes depressed. 



These insects are generally of a grey colour, with black dots and stains. The genus 

 seems to be peculiar to Central America and the Antilles.
