TETYRA. 



GENERIC CHARACTER. 



Thorax very narrow before ; scutel elongated, 

 longer than broad, not covering the sides of 

 the tergum ; head immersed to the eyes in the 

 thorax; antennae five-jointed, second joint longer 

 than the third ; labrum very long, striated ; ros- 

 trum four-jointed, the three first joints subequal; 

 tarsi three-jointed, the first joint longer than the 

 second. 



OBSERVATIONS. 



The genus Tetyra was separated from 

 CiMEx of Linne, by Fabricius, to include 

 those species of which the scutel is very much 

 dilated and elongated, and the antennae five- 

 jointed. As instituted by that author, it is 

 perfectly synonymous with Scutellera of 

 Lamarck and Latreille. Leach made a different 

 disposition of these genera. He restricted the 

 genus Scutellera to those species that have 

 the abdomen entirely covered by the scutel, 

 plate 43.
