 rows of punetures, the intervals often more stroniily elevated; front

KEY TO INDIANA GENERA OF lATHRIDIINI. 



a. Disk of thorax marked with costse or ridges; eyes on sides of head; 

 elytra not connate. 



b. Presternum not reaching the hind border of the prothorax, the epi- 



mera uniting on the median line. I. I.rATHRiDius. 



fc&. Prostemum reacliing the Iiind margin of the prothorax and thus 

 separating the epimera. Coninomus. 



(t(i. Disk of tliorax without costte. 



c. Eyes large, not very dist;nit from autei^nje; scutellum distinct. 



II. Enicmus. 



cc. Eyes small or minute, remote from antennjp; scutellum indistinct; 



middle cox:b separated. III. Cartodere. 



T. TjATHRiDirs TIerbst. 170:^ (Gr., "secret or hidden.") 



Small, glabrous, shining brown species, having the front angles 

 of thorax more oi- less lobed and the sides sinuately convergent to 

 a point near the middle, thence divergent to base. Elytra fully 

 twice as wid(^ as thorax, broadly ovate with the apex somewhat 

 jHiinted. Seven species are recognized by Fall as belonging to the 

 North American faiuia. Of these one occurs in the eastern United 

 States and Indiana, while another, breviclnvns Fall, known by the 

 2-,iointed club of antenna', was described from iMichigan and may 

 inhabit the northern part of the State.

 Oblong. Dark reddish or chestnut brown, shining; legs and antennae 

 slightly paler. Antennae reacliing hind angles of thorax, ratlier slender.
