FAMILY LIT. CERAMBYCIME. 



Tribe Y. POGONOCHERINI. 



The genera comprising' this tribe are represented by small, some- 

 what flattened species, having the tarsal claws divaricate; scape of 

 antennas short and stout without cicatrix; thorax with a spine or 

 tubercle each side. They usually bear long, erect (flying) hairs in 

 addition to the ordinary pubescence, and the antennas are only a 

 little longer or shorter than the body, the outer joints gradually 

 shorter. Three of the eight genera composing the tribe are known 

 to be represented in the State, while a member of another probably 

 occurs.

LXIY. POGONOCHERl S. 



cc. Thorax with feebly rounded sides ; pubescence short. 



LXY. Ecyrus. 



ml. Thighs not club-shaped; vertex flat or convex; antennal tubercles not 

 prominent ; eyes coarsely granulated, lower lobe as wide as long. 



LXVI. Etjpogonius. 



Hoplosia nubila Lee, length 9-12 mm., is said to breed in twigs 

 of dry beech and linden and is recorded from Michigan, Illinois

LXIV. Fogonocherus Latr. 1829. (Gr., £ ' beard + to enjoy.") 



In this, as well as the next genus, the eyes are not coarsely 

 granulate ; thorax with faint dorsal tubercles, elytra feebly carinate 

 on sides; femora club-shaped; hind tarsi short, the first and second 

 joints equal. Two species may occur in the State, though but one 

 has been taken.
