Aphodius inqiiinatiis Hbst. April i, 7. 



Smaller than fiiiietarius. Introduced from Europe, and found in 

 the same situations as A. Huietarius. Sandy lane near Devil's Hole; 

 in spring flight and quite common at the Devil's Neck April 7. 



Aphodius termhvalis Say. April 4. 



Quite small; scarce; perhaps typical of sandy localities. Hiber- 

 nates beneath cow dung and partly buried logs. Taken under boards 

 in blowsand with Anisodactylus rusticus and Opatrinns notus. 



Geotnipes opaciis Hald. April 8. 



Restricted to sandy localities, occurring under cow dung in 

 pastures, often burrowing into the ground beneath. Found dead 

 with Harpalus caliginosus under cow-chips, in bunch-grass pasture 

 at the Devil's Hole. 



Trox scabrosits Beauv. ; Hood, det. July 5. 



Occurs on carrion or bones in sandy localities. Scarce in Illi- 

 nois. Taken with Sapriims pennsylvanicus and Necrophorus on the 

 carcass of a field-mouse. 



Serica sericea 111. June 23. 



Occurs beneath shelter of various kinds; hibernates in pupal stage 

 beneath partly buried logs. Found in the stomach of a toad, Bitfo 

 Icntiginosiis americaniis. A number of these toads were taken in 

 the mixed forest of the river dunes. Four stomachs contained the 

 remains of numbers of two species of ants, several elaterids, scara- 

 bseids, and a weevil, PJiytoiioiiius puiicfatiis, with a few cutworms. 

 Serica is a forest-inhabiting species. 



Lachnostcrna prunina Lee. ; Hood, det. April 8. 



One of the common May-beetles. Scarce. Blatchley found it 

 only in Lake and Vigo counties (sandy regions). Taken along the 

 beach of Lake Michigan. Rang^es from Ohio and Michigan to Kan- 

 sas and Texas. The larv?e live under ground, eating the roots of 

 grasses and other plants; the adults probably eat leaves of trees; 

 they are nocturnal feeders. In digging up the burrow of a spider, 

 in the bunch-grass at the Devil's Hole, quite an excavation was 

 made; the Lachnostcrna was seen crawling out of the old pupal cell 

 into this excavation, at a depth of nine or ten inches. 



Lachnostcrna niicans Knoch. ; Hood, det. July 3, 29. 



A common species of early summer. Four dead specimens found 

 on two different occasions on bare blowsand, where no doubt they 

 had lieen blown after death. In April, 1910, large numbers of dead 

 insects were collected in hollows on the sandy beach of Lake Michi-
