1111 (3301). Mycetophagus punctatus Say, Journ. Phil. Acad. Nat. Scl, ' 



V, 1820, 260 ; ibid. II, 321. 



Oblong-oval, subdepressed. Head and thorax black- 

 ish ; elytra reddish-yellow with black spots ; one large, 

 common, surrounding the scutellum ; another smaller on 

 each] at middle, usually confluent with the lateral mar- 

 gin and extending narrowly along it, and a third form- 

 ing a common subapical erossband; antenna reddish, the 

 apical half more or less fuscous. Thorax coarsely and 

 evenly punctured. Length 4.5-5,5 mm. (Fig. 219.) 



Southern half of State, frequent; less so in the 

 (Original.) northern counties. April 6-September 29. Prob- 

 ably hibernates. Occurs beneath loose bark and in fungi, especi- 

 ally in low moist woodlands. 



1112 (3393). Mycetophagus flexuosus Say, loc. cit. 



Resembles punctatus but much smaller. Elytral markings very vari- 

 able, usually nearly as in punctatus, but the middle and subapical black 

 spots are larger, with their edges very uneven, and there is usually a small 

 round spot on humerus. Length 3-4 mm. 



Throughout the State; frequent. April 11-Qctober 6. Occurs 

 in fungi and in spring sometimes at sap. 



Casey's sub depress us is only a color variety of 'flexuosus in 

 which the black spots have become enlarged so as to cover the 

 greater part of the elytra, leaving only a narrow oblique reddish 

 line composed of two or three spots on basal third, another similar 

 line behind the middle and a spot near the apex. It occurs com- 

 monly with typical flexuosus, and individuals showing the gradual 

 merging of one color variety into the other are frequent, several of 

 them being in the collection at hand.

Sci., II, 1844, 114. 



Oblong-oval, moderately convex. Dark reddish-brown ; elytra each with 

 an irregular subhumeral yellowish spot which sometimes extends nearly to 

 suture, and also a transverse oblong one on apical third ; antenna? and palpi 

 dull brownish-yellow. Thorax three-fourths wider than long ; sides slightly 

 curved, surface coarsely, densely and unequally punctured. Elytral striae 

 feebly impressed, finely punctate ; intervals densely punctulate, each with a 

 single row of suberect yellowish hairs. Length 3-3.5 mm.
