Abundant along the shore of Lake Michigan and on the 

 sand dunes back from the lake; also found on the sandy 

 beaches of other large lakes in northern Indiana. May 13-Sept. 5.

Slender, subcylindrical. Black, dark brown or greenish-bronzed above ; 

 greenish-blue beneath; the whitish markings, except the apical lunule, 

 usually reduced to one or two minute dots, with rarely a broken humeral 

 lunule and interrupted middle band present. Front without hairs. Thorax 

 sparsely hairy, very finely granulate. Elytra densely punctured, each with 

 a row of larger green punctures near the suture. Length 11-14 mm. 



Throughout the State; one of the most common and widely dis- 

 tributed of tiger beetles. Often found about electric lights and on 

 the walks of the -cities ; also along dry upland roads and especially 

 pathways in open woods. May 25-November 4. 



14 (45). Cicindela clprascens Lee, Proc. Phil. Acad. Nat. Sci., 

 1852, 65. 



Cupreous or greenish-bronzed above ; markings complete and 

 connected along the marginal line. Front hairy. Thorax flat- 

 tened, nearly quadrate, slightly rounded at sides, thinly clothed 

 with white hairs. Outer margin of male elytron slightly sinuate;

 the tip. Length 12-14 mm. (Fig. 23.) 



Frecpient along the sandy beach of Lake Michigan, near 

 Pine, Lake County and Dune Park, Porter County ; also a 

 single example from a sand bar in Putnam County. Probably wide- 

 ly distributed in the State. July 5-September 1. 



Those found along the beach of Lake Michigan are more slender, 

 less strongly punctured and with the marginal tooth of the female 

 elytron more obtuse than in the Putnam County form. They are to
