THE SHOBT-WIXGED ?( ATEXGER BEETLES. 407 



Vigo, Orange and Posey counties; scarce. April 13-May 24. 

 In one specimen there is a faint small pale .spot on the middle of 

 each eh^tron. 



7S5 (2342). STE>-rs scabiosus Casey. Rev. Sten., 1SS4. 60. 



Elongate, slender. Black, shining, sparsely clothed with very fine gray 

 [lubescenc-e. yellowish on the abdomen : legs fuscous above, reddish-brown 

 beneath. Head twice as wide as long, surface between the eyes excavate, 

 finely and closely punctate. Antennae reaching middle of thorax, third joint 

 one-half longer than fourth. Thorax T\idest just behind the middle, finely 

 and densely punctate and with a fusiform impression on median third. 

 Elytra slightly longer than thorax, finely, closely and irregularly punctate. 

 Abdomen slightly narrower at base than elytra, feebly tapering to apex, 

 finely, evenly and rather sparsely pxmctate. Length 3-3.3 mm. 



Koscinskci County ; rare. -Tune 24. Two specimens taken while 

 sweeping low herhs in swampy places. 



The other species of Division C. briefly characterized in the 

 above key. were with the exception of nanus Steph. and pumilw 

 Eriehs.. all described by Ca.sey in his Revision, and it is probable 

 that a number of them will prove to be synonymous. His types of 

 these species were from points mostly in ^Michigan, which would 

 render their occurrence in Indiana, especially the northern por- 

 tion, very probable, though as yet specimens have not been taken. 



Division D. 



In this group the elytra are sculptured as in Division C, but the 

 thorax is without an impression along the median line. The beetle. 

 says Ca.sey, "should be held in such a manner that the light will 

 pass obliquely across the highest point of the thorax and perpen- 

 dicular to its longer axis. If there is no sign of even a narrow 

 longitudinal shade, the species belongs to this division. If there 

 be even a faint shadow extending along the middle of the disk, the 

 insect may be considered as belonging to Division C." 



KEY TO INDIANA SPECIES OF DIVISIOH D. 



(/. Transverse carinte of abdomen with cusps.

c. Elytral suture longer than thorax; longitudinal elevation between 



the eyes almost obsolete; length 3-3.4 mm. TS6. coiowus.

 tween the eyes evident, broad : thorax more coarsely and roughly 

 punctate; length 3.5 mm. 7S7. svspectus. 



66. Transverse carinse with three cusps. 



d. Elytral suture slightly shorter than thorax ; head wider than ely- 



tra ; antennal joints three, four and five uniformly decreasing in 

 length ; femora pale beneath ; length 2.5-2.9 mm. 788. htcmelis.
