nearly to suture; another broader, behind the middle, and usually a smaller 

 one on each side, dull yellow ; these sometimes confluent so as to make the 

 larger portion of the surface yellow. Thorax one-half wider than long, 

 sides strongly curved, disk sparsely, coarsely and equally punctured. Ely- 

 tral stria? with deep, coarse punctures. Length 4-4.5 mm. 



Posey County; rare. April 9. Readily known by its elongate 

 form, parallel sides and evenly punctured thorax.

ScL, VIII, 1856, 13. 

 Elongate, narrow, parallel. Piceous-black ; elytra with numerous small 

 reddish-yellow spots, often more or less confluent into oblique bands and 

 sometimes covering the greater part of the surface ; under surface, legs and 

 basal half of antenna? pale, the last five joints of the latter dusky and 

 slightly larger. Thorax distinctly narrowed at base, the margin finely ser- 

 rate. Elytral stria? finely punctured, indistinctly so at tip. Length 3.5- 

 4 mm. 



Vigo County; scarce. October 21. Occurs in fungi, especially 

 that growing on hickory logs and stumps.

II, 1844, 113. 



Oval, rather strongly convex. Piceous black; legs and antenna? paler; 

 elytra each with two irregular oblique reddish-yellow stripes, one extending 

 from humerus nearly to suture, the other behind the middle ; an oval sub- 

 marginal spot between the two and another at apex. Thorax less than 

 twice as wide as long, widest at base, hind angles obtuse, disk coarsely and 

 evenly punctate. Elytra with impressed, entire rows, of coarse deep punc- 

 tures. Length 4.5 mm. 



Kcsciusko. Vigo. Dubois and Pesey counties; rare. April 13- 



Oetober 21. Taken from fungi on hickory stumps and by sifting 



debris. 



IT; Lita-rgus Erichs. 1832, (Gr.. "swift of foot.") 



The species belonging here are much smaller and more narrowly 

 oval than in Mycetophagus. The antennae end in a 3- jointed club 

 and the epipleura? are concave. Four species have been taken in 

 the State, while a fifth probably occurs.
