IO4 MEMOIRS ON THE COLEOPTERA 



interval rugulose and with similar confused punctures broadly 

 throughout; pygidium finely, sparsely punctate, rugulose basally, 

 smoother in the male; metasternum short and rather broad between 

 the middle coxae, flat, abruptly, steeply sloping anteriorly; prosternal 

 process very short, triangular; anterior tibiae with the two external 

 teeth extremely and peculiarly approximate and near the base of the 

 apical process; hind tibiae shorter than the femora and about equal 

 in length to the rather slender tarsi. Length (cf 9 ) 14.5-15.8 mm.; 

 width 8.5-9.0 mm.; length of antennal club (cf ) 2.25; (9 ) i-45 mm. 

 New York to North Carolina (Southern Pines) and westward to 



Illinois brevipes Lee. 



A Similar to brevipes but rather smaller in size; head similar but with 

 still larger and more prominent eyes, these separated in the male 

 by only three-fourths more than their own width; prothorax 

 similar but shorter, four-fifths wider than long; elytral striation 

 still coarser and more impressed. Length (cf ) 14.0 mm.; width 



7.6 mm. Indiana discernens n. subsp. 



Form cylindric-oval and very convex, still stouter than in brevipes, 

 shining, black or piceous-black; head and clypeus (cf) similar, 

 except that the latter is shorter, more than twice as wide as long; 

 antennal club much longer than the stem, the sixth and seventh 

 joints of which are similarly oblique but less transverse; eyes in the 

 male very convex, separated by distinctly less than twice their width; 

 prothorax differing decidedly in outline, widest at base, the sides 

 thence moderately converging and feebly, evenly arcuate to the 

 very obtuse apical angles, viewed dorsally, but with the usual medial 

 arcuation when viewed obliquely, less transverse, about three-fifths 

 wider than the medial length, which is greater, owing to the more 

 prominent median lobe; lateral bead turning more into the base 

 than in brevipes; apex still more nearly truncate; punctuation and 

 sublateral pit similar; scutellum a little larger, fully two-fifths as 

 wide as an elytron; elytra barely longer than wide, almost similar 

 in form and sculpture; pygidium rather more punctured; under sur- 

 face and legs nearly similar, except that the tarsi are a little shorter 

 and thicker, the widely diverging arms of the ungual cleft shorter and 

 apically more obtuse. Length (cf) 15.5 mm.; width 9.0 mm.; 

 length of antennal club 2.4 mm. Pennsylvania. . conicicollis n. sp. 



I think there can be comparatively little doubt that conicicollis is 

 truly a different species, as shown by its stouter outline and shorter 

 elytra, conical and less transverse prothorax, slightly longer 

 antennal club and still larger eyes; especially, also, by the some- 

 what larger scutellum. 



Tribe GENIATINI. 



The following Geniatids seem to be undescribed, or at least I 

 have not been able to find descriptions fitting them at all closely:
