 VII. 1850. 255. 



Oblong, moderately elongate. Dark reddish or chestnut brown, shining. 

 Head coarsely and densely punctured. Thorax narrowed in front, sides 

 regularly curved, margin not crenate and with short cilise; surface coarsely, 

 deeply and sparsely punctured, often with large smooth spaces. Elytral 

 punctures coarse and very dense, the discal costse indistinct. Male with an- 

 tenna 1 club as long as stem; abdomen broadly flattened at middle, the fifth 

 segment with a feeble curved elevation. Length 14.5-10 mm. (PL V, fig. 

 402.) 



Posey County; scarce. April Ifi-May 10. Those on the earlier 

 date were taken from beneath bark of oak stumps and logs. 



GROUP E. 



All the members of this group are more or less hairy and have 

 the antenna 10-jointed, the club of male shorter than in the pre- 

 ceding groups; elypeus emarginate; inner spur of hind tibia 1 of 

 male fixed and rather long; claws armed with a strong median tooth. 

 Three of the four known species have been taken in Indiana, while 

 the other probably occurs. 



KEY TO SPECIES OF GROUP E. 



(i. Basal margin of thorax with an impressed line reaching from hind an- 

 gles nearly to middle: sides of thorax not subangulate. 

 l>. Elytra with rows of erect hairs. 1830. HIRTICULA. 



hh. Elytra with line scattered suberect hairs. 1831. DELATA. 



mi. P.asal margin of thorax without impressed line, the median line usually 



finely carinate; sides subangulate. 



r. Surface of elytra more or less hoary or pruinose; pubescence fine, uni- 

 form and recumbent. 1832. ILICIS. 

 n: Surface not pruinose: elytra with rows of shorr erect hairs in addi-

( )bloiig, slightly broader behind. Reddish-brown to dark chestnut-brown, 

 shining; head and thorax with erect hairs. Elytra with five lines of erect 

 hairs along the usual cost.-e. ("lypens rather deeply emarginate, surface 

 coarsely and very densely punctured. Thorax narrower at apex, sides 

 usually entire, with short cilia*; surface with coarse, rather sparse variolate 

 punctures. Elytra with much finer, rather dense, feebly impressed punc- 

 tures, the margin fringed with long hairs. Male with antennal club a little 

 longer than the funicle ; abdomen flattened at middle, the fifth segment moi'e 

 depressed behind the middle, with a short oblique ridge each side, sometimes 

 with a well marked transverse ridge in front of middle. Length li;.5-V.) mm. 

 (PI. V. fig. 40.",.) 



Throughout the State; common in the southern counties, less so 

 in the north. March 25-July 1. Those on the earlier date from 

 beneath stones. Quito variable in form and si/e, but readily known 

 by the lines of erect elytra! hairs.
