at middle and united by a transverse ridge, thus dividing tlie groove into 

 two fcvesB or depressions, the hinder one of these wi-th a large rounded 

 fovea on each side; apical half with a transverse fovea each side. Elytra 

 with rows of small but distinct tubercles, bearing short, erect brownish 

 hairs; intervals with a few very small tubercles and scattered granules. 

 Front tibiae with a small marginal tooth near the angle. Length 5-6 mm. 



Putnam, Vigo, Lawrence and Posey counties; frequent. June 

 2-Septomber 26. Resembles closely the next and probably confused 

 with it in many collections. Known by the erect brownish hairs of 

 the elytral tubercles, which can be readily seen by viewing the speci- 

 men from the side. Listed as L. foveicollis Har.

 In form, color and sculpture of thorax this species very closely resem- 

 bles insularis. Thorax with sides a little less rounded, and more convergent 

 in front. Tubercles of elytra with yellowish scale-like hairs which are 

 semi- or wholly prostrate. Length 5-6 mm. 



Southern half of State; scarce. Februan^ 14-November 30. 

 This species and the next hibernate beneath rails and chunks in 

 fence corners where dead leaves have accumulated. It is possible 

 that all species of Trox so hibernate, as several others have been 

 taken very early in spring or late in autumn. When touched or un- 

 covered all the species "play possum" or simulate death.
