KKY TO EASTERN GENERA OF RHYPAROCHROMINI. 



a. Front margin of pronotum with a distinct ring-like collar; head 

 exserted, the postocular space usually subequal to that between 

 eyes and base of antenna?; hind tibiae with short, rigid bristles. 



I. Ozophora, p. 414. 

 aa. Front margin of pronotum without a collar; head inserted in 

 thorax to, or almost to, eyes; hind tibiae without rigid bristles. 

 b. Side margins of pronotum strongly carinate and refiexed ; head

 behind eyes; first joint of beak shorter than head; front tibiae 

 strongly curved. II. Tempyra, p. 419.

I. Ozophora Uhler, 1871, 102. 



Small elongate-oval species having the head porrect, wider 

 across the eyes than front margin of pronotum ; tylus decurved, 

 not reaching middle of first joint of antennae; eyes large, 

 coarsely facetted ; beak reaching hind coxae or first ventral, first 

 joint as long as head; antennae slender, more than half the 

 length of body, first joint stoutest, almost as long as head, sec- 

 ond longest, third and fourth subequal in length, the third 



"Uhler in his Check List. p. 15, records Pamphantus elegantulus Stal (1874, 

 157), a Cuban species, from the "Southern States." but no other mention of its oc- 

 currence in this country can be found. As the genus is not included by Ranks in his 

 Catalogue, nor by Barber in his 1918 paper, it is here omitted.
