KEY TO INDIANA SPECIES OF LIODES. 



a. Elytra with regular rows of punctures. 



6. Ninth row of punctures marginal in the greater part of its length, 



distant from the margin at base only. 

 c. Elytra strongly sinuate at sides, the ninth stria very distant from 



margin at base. 



d. Intervals of elytra distinctly punctulate. GLOBOSA. 



dd. Intervals smooth or nearly so. POLITA. 



cc. Elytra not sinuate at sides, the ninth stria not very distant at 

 base; intervals smooth. 558. DISCOLOR.

 elytra not sinuate. BLANCHARDI. 



<ia. Elytra with more or less confused rows of punctures. 

 e. Ninth row distant from margin its entire length. 



/. Punctures of stria? rather coarse, those of intervals very fine. 



559. BASALIS. 

 ff. Punctures of striae fine, those of intervals quite evident. 



OBSOLETA. 



ee. Ninth stria marginal, distant from margin for a short distance at 

 base only ; rows of punctures much confused, forming nearly double 

 strife. (Fig. 143, 6.) GEMINATA. 



L. globosa Lee. and L. polita Lee., both piceous black and 3-3.5 

 mm. in length, have been recorded from Kentucky.

103. 



Hemispherical, very little longer than wide. Piceons-black above, red- 

 dish-piceous beneath, shining. Thorax without punctures, the hind angles 

 rectangular. Elytra as wide as long, each with eight entire rows of rather 

 coarse punctures, the ninth distant from the margin at base, but joining it 

 slightly behind the middle; intervals flat, smooth, the alternate ones with 

 a very few distant coarse punctures. Length 2.5-3 mm. 



Marion and Posey counties scarce. June 6-August 3. 



L. blanchardi Horn, was described from Massachusetts and has 

 been since recorded from Cincinnati. 



559 (1787). LIODES BASALIS Lee., Proc. Phil. Acad. Nat. Sci., VI, 1853, 285. 



Broadly oval, convex, shining. Piceous black; elytra with humeral 

 space of varying width, extending from sides almost to suture, orange-red. 

 Thorax minutely and sparsely puuctulate. Elytra with eight entire rows 

 of rather fine, much confused punctures, the rows appearing double. Length 

 2.5 mm. 



Posey and Perry counties; scarce. May 1-May 20,
