sects Injurious to Vegetation, p. 470. 1869) states that it preys upon 

 canker-worms, both on the ground and by ascending trees. 



Galerita janus Fabr. 



A specimen was found under the bark of a decaying log in the 

 upland Bates forest (Sta. IV, a) Aug. 23 (No. 171). This common 

 beetle is frequently found in such situations, and seems to have a 

 preference for relatively damp places. I have taken the adult as 

 early as March 23 under bark of logs in the sap-wood stage of decay 

 at Urbana, 111., where it was found associated with single dealated 

 females of Camponotus herculeanus pennsylvanicus, Passaliis cornu- 

 tus, pyrochroid larvae, the caterpillar Scolecocampa lihurna, and the 

 slug Philoniyciis carolinensis. 



This species is a fairly common one. I found it abundant at 

 Bloomington, 111., where it was taken April 15, May i, and June 22. 



The larva has been described by Hubbard (Psyche, Vol. i, pp. 

 49-52. 1875). 



COCCINELLTDiE 



A species of lady-beetle was found upon a fungus growing on a 

 stump in the upland forest (Sta. IV, a) Aug. 17 (No. 81). Asso- 

 ciated with the beetle on the fungus were large numbers of the snail 

 Pyra midula perspectiva. 



ELATERIDiE 



Melanotus sp. 



A larva belonging to this genus (No. 125) was found Aug. 22 

 under the bark of a decaying stump (Sta. IV, h) in which the sap- 

 wood was destroyed, the remainder being sound though discolored. 

 It was associated with the slug Philomyciis carolinensis and the 

 caterpillar Scolecocampa lihurna. 



Corymbites sp. 



A larva belonging to this genus (No. 113) was found in drifted 

 leaves and dead wood at the mouth of a ravine in the lowland for- 

 est (Sta. IV, c). 



Asaphes mcninoniits Hbst. 



This click-beetle was taken at the mouth of a ravine in the low- 

 land forest (Sta. IV, c) Aug. 20 (No. 113) in drift composed of 

 dead leaves and rotten wood. 



Lampyrid^ 



Caloptcron terniinale Say. Black-tipped Calopteron. 



This interesting beetle was taken in the damp lowland forest (Sta.
