THE TIGER BEETLES. 



Lake and Lawrence counties; rare. May 7-July 27. Occurs 

 in shaded pathways on high, dry hills. Usually placed as a variety 

 of sex gut tat a, but Leng considers them distinct. 



6 (25). CICINDELA PURPUREA Oliv.. Ent.. II. 17!>4. 14. 



Reddish cupreous, margins ;iud suture of elytra green; mark- 

 ings consisting of a narrow oblique middle band, an apical dot 

 and sometimes an anteapical and humeral dot. Thorax deeply 

 impressed, granulate and rugose. Length 14-10 mm. (Figs. 13 

 and 17.) 



This handsome beetle has so far been noted only in 

 southern Indiana, where it has been taken in a half dozen Flg - 17 



(After Leng.) 



or more counties. However, it probably occurs through- 

 out the State, as its general range includes the entire United States. 

 It frequents the grassy margins of roads and meadow pathways. 

 Double brooded and probably hibernates. April 23-October 15. 



The variety linibalis King., in which the middle band is long 

 and sinuate and with humeral, posthumeral, apical and anteapical 

 dots usually present, probably occurs sparingly in the State, its 

 range being given as "Maine to Colorado and Kansas." 



7 (20a). CICINDELA FORMOSA GENEROSA. Dej., Spec. V. 1831, 231. 



Dull reddish cupreous or brownish-bronzed ; white markings wide, 

 prominent and connected on margin, the middle baud bent backward, then 

 forward and almost reaching the suture. Thorax broader than long, granu- 

 late, very hairy on the Hanks. Length K5-1S mm. (Fig. 14.) 



This eastern form of Say 's formosa has been taken only in Lake, 

 Porter, Laporte, Vigo, Perry and Posey counties, where it occurs in 

 numbers on bare sandy spots and along sandy roads. May 13-Oc- 

 tober 1. It is more wary and difficult to capture than most of its 

 kind and when flushed often makes a prolonged flight. Generosa 

 and unipunctata are the largest of our tiger beetles, and the former 

 will probably be found over most of the sand covered areas of the 

 State. 



S (32). CICINDELA VULGARIS Say, Trans. Amer. Phil. Soc.. I, 1818, 

 , 409; ibid. II, 422. 



Brownish-bronze above, dark green beneath; elytral markings

consisting of humeral lunule obliquely prolonged; a middle band 

 but slightly expanded on margin, entering obliquely and bent at 

 r-:,r, js. an obtuse angle, and an apical lunule. Length 13-10 mm. (Figs. 



Alter Leng.) If, and IS.)
