Throughout the State; frequent. January 24-Oetober 21. Oc- 

 curs in fungi. 



1098 (3375). CRYPTOPIIAGUS NODANGUU s Xiniin., Trans. Ainer. Ent. Soc., 



II, ISIM). 257. 



Elongate-oblong. Dark reddish-brown, strongly shining. Antennae reach- 

 ing base of thorax, the flub less stout than in fuiiyicoltt. Thorax finely, 

 equally and rather closely punctured. Elytra more coarsely punctate. 

 Length '2 mm. 



Marion County; rare. April 7. 



IX. HENOTIOUS Thorn. 1870. (Gr.. "in unity.") 



Eesembles Cr)ii>t(>i>lKt<jtis very closely, but is distinguished by the 

 thorax having the edges finely toothed and without thickened apical 

 space at front angles, and by the front above the base of antenna 1 

 being finely margined. One of the two known species occurs in 

 Indiana. 



1001) (3303). IlKNOTicrs SERRATUS Gyll., Insect. Suec., 1S27. 



Oblong, suhconvex. Dark reddish-brown to blackish, sparsely pubes- 

 cent with yellowish hairs, the legs and antenna 4 paler. Thorax transverse, 

 deeply and rather closely punctured, the sides nearly parallel, the edges 

 with eight to ten fine teeth. Elytra distinctly wider than thorax, obtusely 

 rounded behind, sparsely and coarsely punctured. Length 1.7-2 mm. 



Marion and Posey counties; scarce. April 23-May 11. Occurs 

 in dry fungi about the stumps of oak. 



X. PTERYNGIUM Reitt. 1887. (Gr., "wing + little.") 



The species of this genus are readily recognized by the rather 

 narrow, strongly depressed, finely pubescent body. The basal seg- 

 ment of the abdomen is as long as the next three combined. Of the 

 two species known, one occurs in Indiana. 



1100 (- -). PTKRYNGIUM MALACTM Casey. Journ. X. Y. Ent. Soc., VIII. 



11HX), 102. 



Oblong, parallel, depressed. Pale reddish-yellow, shining. Antennre as 

 long as head and thorax, rather slender. Thorax one-third wider than 

 long, finely and closely punctured; sides distinctly curved, hind angles 

 rounded. Elytra scarcely wider than thorax and about three times as 

 long, finely and sparsely punctured; pubescence scarcely evident. Length 

 1.7 mm. 



Vigo County; rare. February 10. One specimen lakcii from 

 beneath a log in upland sandy woods.
