36 FAMILY II. — CARABIDiE. 



County. June 27-Scptcmber 5. As its color harmonizes so closely 

 with that of its resting place, it must be marked down and then 

 kept in view until close enough to capture with the net. It is said 

 to fly to electric light. 



16 (64). Cicindela RUFivENTKis Dej.. Spec, I, 1825, 102. 



Dark smoky brown, bronzed above ; bluish-green beneath, ab- 

 domen red; elytral markings consisting of apical lunule and 

 humeral, posthumeral, marginal and two discal dots ; the latter 

 sometimes wanting, sometimes united to form a short, sinuate 

 middle band. Head finely striate, not hairy. Thorax subquad-

(After Leng.) < V12 mm . (Fig. 25.) 



This species has so far been taken in Indiana only on bare spots 

 on the slopes and tops of high hills near Wyandotte Cave, Craw- 

 ford County. Here it is quite common from June 15 to Septem- 

 ber, and can be readily approached and easily taken with a net. It 

 probably occurs in like situations in many localities in the southern 

 third of the State. 



Cicindela rnarginipcnnis Dej. has been taken by Dury on a sand 

 bar of the Little Miami River near Batavia Junction, Ohio. May 

 17. It therefore very probably occurs along the streams of the 

 southeastern portion of Indiana. 



Family II. CARABIDiE. 

 The Ground Beetles. 



This family has more representatives in Indiana than any other 

 family of Coleoptera. Its members are to be looked for anywhere 

 on or close to the ground, where by day they usually hide beneath 

 whatever cover presents itself. At night they roam about m eager 

 search for anything which will furnish food. All the species have 

 long legs and run with great rapidity. While the inner wings are 

 present in most forms, they seldom attempt to escape by flight ; 

 though some of the smaller ones are seen flying in numbers during 

 the first warm days of spring or about electric lights during summer 

 evenings. The principal characters of the family may be briefly 

 diagnosed as follows: 



Head narrower than thorax, directed forward ; mentum deeply 

 emarginate ; maxillae with the outer lobe destitute of a movable 

 hook at the tip; antenna 11-jointecl, filiform, inserted under a 

 frontal ridge behind the base of the mandibles, the joints (except
