946 FAMILY L. SCARAB.i;iRK. 



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

 two fovere or depressions, the hinder one of these with a large rounded 

 fovea on each side; apical halt" 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 tibia? with a small marginal tooth near the angle. Length 5-6 mm. 



Putnam. Yitio, 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. fovelcollis TTar.

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. February 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.

Elongate, subovate. Dull brownish-black. Clypeus rounded, densely 

 punctured; front with minute tufts of reddish-brown hairs arranged in a 

 transverse sinuous line. Thorax twice as wide as long, sides feebly and 

 evenly curved, ciliate; dorsal groove very feeble, surface finely and evenly 

 punctate, sparsely clothed with short, erect brownish hairs. Elytra with- 

 out tubercles, but with numerous tufts of reddish-brown, scale-like hairs 

 arranged in regular rows. Hind tarsi with joints 2-4 longer than wide. 

 Length 6-6.5 mm. 



Throughout the State ; frequent. March 20-December 12. Oc-

 of trees.

Form of (cqualis. Black, somewhat shining, when clean. Thorax with 

 median groove a little more distinct and a shallow impression each side 

 near base, the surface less covered with bristly hairs, otherwise as in 

 irfliuilix. Elytra with rows of oblong, shallow punctures, the alternate in- 

 tervals more elevated and bearing oblong tufts of brownish hairs; the in- 

 tervening intervals with minute rounded tufts of similar hairs. Hind tarsi
