gins of woods, and in grass-grown raspberry and blackberry 

 patches near the Warren Woods Preserve. At New Buffalo 

 it was common in an open oak woods among the low herba- 

 ceous undergrowth, and about its grassy margins. In the 

 dune area it was found iu. large numbers in a small open'.ng 

 in the edge of the oak dune woods, among clumps of bunch 

 grass and trailing grapevines, in company with M. august i- 

 pcnnis and M. mcxicauns atlauis. Specimens were also taken 

 on grassy roadsides, in dry pastures, and in sandy fields cov- 

 ered with a sparse growth of dr\^ grass and overrun with dew- 

 berry vines. 



The ent.re series taken at New Buffalo in an open oak 

 woods, through which a ground fire had run early in the sea- 

 son, is very dark in color, corresponding to the general tone 

 of the surroundings. This is also true of several of the other 

 species taken here, notably of Spharagenion bolli. A series 

 of M. hiridus taken along the borders of this grove, where it 

 adjoins an area of bare sand and bunch grass, is so light in 

 color as to have been taken at first sight to represent a dif- 

 ferent species. 



This species was taken at Lakeside in August and on Sep- 

 tember iS by Hancock.
