232 FAMILY VI. — COREHLE. 



tubercles ; of female with teeth below fewer, the two or three on apical 

 third of each margin longer and stouter than those preceding. Length, 

 16—21 mm.; width, 6—7 mm. (Fig. 47). 



Vigo, Lawrence and Crawford counties, Ind., scarce, April 

 9— Sept. 18; R. P. Park, Fla., March 26 (W. S. B.) . Not before 

 recorded from the latter State. Occurs on foliage of black- 

 berry and other shrubs along wooded hillsides and borders of 

 thickets. One just emerged as adult was taken April 19 on a 

 red oak tree. Ranges from New Jersey and North Carolina 

 south to Florida and west to Colorado and Oklahoma. It ap- 

 pears to be nowhere common and nothing regarding its food 

 habits has been published. 



Stal (1870, 137) erroneously made this species a synonym 

 of calcarator (Fabr.). In this he was followed by Uhler and 

 other American authors until Van Duzee (1909, 159) pointed 

 out in part the differences between the two. This author stated, 

 however, that calcarator is smaller than alternatus. That is true 

 only of the males, and the difference in size is not great in that 

 sex. All Indiana females of alternatus are a little shorter with 

 body distinctly narrower and abdomen less inflated than in 

 Florida females of calcarator. The two species are easily sep- 

 arated by the characters given above in key and in the descrip- 

 tion of alternatus.

 upper surface and two rows of small spines beneath; tibiae curved and 

 with a rather large tooth near middle, the apical half serrate within.

 straight without teeth. Head, front of pronotum, sternum and legs 

 clothed with a short grayish pubescence. Length, 19.5 — 20 mm.; width
