1802 (5699). DiPLOTAXis soedida Say, Journ. Phil. Acad. Nat. Scl., V, 1825, 



197; ibid. II, 299. 

 Oblong, robust, convex. Reddish-brown to black or piceous, siibopaque ; 

 upper surface clothed with fine, short, suberect, yellowish hairs, those on 

 thorax dense and more erect. Clypeus short, broadly but not deeply emargi- 

 nate ; its surface, as well as that of thorax and elytra, densely, rather finely 

 and more or less confluently punctured. Thorax with a deep impression 

 near the front angles and a distinct but more shallow one near the hind 

 ones, the middle portion more convex ; sides subangulate behind the middle, 

 margin crenate. Elytra with very fine transverse wrinkles between the 

 punctures. Length 11-12 mm. 



Lake County ; rare. July 28-Sept6mber 3. Two specimens from 

 beneath drift on the beach of Lake Michigan near Millers and Pine. 

 It is known only from Michigan, Pennsylvania and Georgia, and 

 seems to be everywhere rare. 



1803 (5716). DiPLOTAXis haepebi Blanch., Cat. Col., Mus. Hist. Nat. Paris, 



1850, 171. 

 Oblong, feebly convex. Reddish-brown or piceous, shining. Clypeus semi- 

 circular, narrowly margined, slightly reflexed, surface rather coarsely and 

 densely punctate. Thorax twice as broad as long, sides feebly rounded ; 

 surface coarsely but not densely punctate. Elytra each with three indis- 

 tinct costse, each of which bears a single somewhat irregular row of punc- 

 tures with a more distinct row on each side; the much broader intervals 

 with numerous coarse, irregular punctui'es. Length 8.5-9.5 mm. 



Throughout the State; common in the southern half, much less 

 so in the northern counties. March 21-October 1. Occurs in early 

 spring and late autumn beneath logs, leaves and stones, where it 

 probably hibernates sparingly as imago, and commonly in the pupal 

 stage. Also occurs at electric light and sparingly on foliage. 



1804 (5717). DiPLOTAXis feondicola Say, Journ. Phil. Acad. Nat. Scl., V, 



1825, 198 ; ibid. II, 299. 

 Oblong-oval, conve.x. Pale to dark chestnut brown, feebly shining. Cly- 

 peus subtruncate at apex, its margin more strongly reflexed and surface 

 more finely punctate than in harperi. Thorax two-thirds wider than long, 

 sides broadly rounded, surface rather finely and somewhat densely punc- 

 tate. Elytra each with three feeble costte, each bearing a single regular row 

 of punctures and a row each side ; the intervals with the punctures more 

 regularly placed than in harperi. Length 7-8 mm. 



Lawrence, Crawford and Posey counties; frequent. May 10- 

 July 3. Occurs beneath stones and logs. A shorter and more con- 

 vex species than harperi, easily distinguished by the form of the 

 clypeus. Probably occurs throughout the State.
