In the diagnosis I have described the elytra as inipunctate and 

 this is true generally, and as compared with other species, but it 

 must be admitted that in .some of the Southern specimens of unicolor 

 the elytra are evidently punctulate. 



The observation that the front is hairy only in the % and scarcely 

 at all hairy in the 9 is due to Mr. H. C. Fall (Ent. News, xii, p. 

 310). This species and its varieties delight in open sandy spots, free 

 from vegetation. In the Pine Barrens of New Jersey, where there 

 are square miles of white sand covered with pines and little oaks, 

 but traversed by innumerable roads and wood paths, modesta is 

 abundant from the earliest warm day in Spring until June and 

 again after September 1st; ruglfroiis occurs also but less abund 

 antly. There my friend, Mr. William T. Davis, and I have spent 

 many hours, catching and liberating specimens of modesta and rvc/i- 

 frons, seeking to find hybrids between the two, and finally conclud- 

 ing that, although they are evidently very closely allied, these two 

 varieties breed true to themselves as a general rule. I, therefore, 

 propose to retain all the varietal names for this species now in use. 



When a net is placed over a modesta or a rugifrons, the beetle will 

 often bury itself in the dry sand and evidently lies very still. Often 

 it cannot be found while the net is on the ground, but directly our 

 careful moving of the sand discovers its hiding place, it becomes as 

 active as a "jack-in-a-box" and usually makes its escape.
