II. CiciNi:)ELA Linn. 1735. (L., "a candle or taper.") 



This genus is represented in the United States by 75 or more 

 species and many varieties. In shape they are very uniform, but 

 ditfer nuich in size and color, and have the head large, with promi- 

 nent eyes; thorax varying from cylindrical to a tlattened trajie- 

 zoidal form and narrower than head ; elytra usually quite convex 

 and subparallel at the sides with the tips usually rounded, emar- 

 ginate in one group. 



Unlike mo.st other members of the family the species of Cicin- 

 dcJa are diurnal in habit, hiding by night and on cloudy or rainy 

 days in holes dug in the sand, or beneath bark, chips, stones and 

 rubbish. On bright sunny days, however, they are out in numbers, 

 frequenting those haunts for which nature has fitted them. Here, 

 as long as motionless, their hues blend with their surroundings in 

 such a manner as to render them unnoticeable to higher forms. It 

 is very ])ro1)able that several species which occur in early spring 

 hi])ernate in the perfect or imago stage. A number of them are 

 double brooded. 



Fifteen members of the genus have been taken in Indiana, while 

 two others may occur. These may be distinguished one from an- 

 other by the following table. Since in it numerous references are 

 made to the white markings on the elytra, the following explana- 

 tory terms regarding them are given :
