XLVI. Typocerus Lec. 1850. (G-r., " impression + horn.") 



The members of this genus are more robust than those of Stran- 

 galia, but have the same tapering form. From the species of Lep- 

 tura they are distinguished by the large impressed poriferous 

 spaces on the antennae. These are near the bases of the sixth or 

 seventh and following joints and appear as elliptical or elongate 

 smooth spots. Three species have been taken in the State, while 

 another perhaps occurs. -
