THE LONG-HORNED WOOD-BORING BEETLKS. 1051 



Vigo, Lawrence and Crawford counties ; frequent. May 19-July 

 22. Occurs on flowers of sumac and wild hydrangea. 



Bellamira scalaris Say, chestnut-brown to black in hue, elytra 

 marked with paler, as shown in Fig. 444, 20-27 mm. in length, 

 ranges throughout the Eastern United States and has been recorded 

 from Michigan and Ohio. 



XLV. STRANGALIA Serv. 1835. (Gr., "a rope or halter.") 



The very slender form, with elytra tapering greatly from base 

 to tips will serve to separate the members of this genus. In our 

 species the last ventral segment of the male is strongly excavated 

 and the sixth and following antennal joints have small oval, de- 

 pressed poriferous spaces near the tips. Thorax bell-shaped, much 

 narrowed in front, hind angles prominent, acute, base Insinuate. 

 Four species have been taken in the State. They occur especially 

 on the flowers of wild rose, wild hydrangea and other summer 

 blooming plants.
