In the material before us, the series from eastern Pennsylvania 

 to Virginia shows the extreme, and what may be considered typical, 

 development of this race. It may be noted that this race is found 

 along the Delaware in New Jersey, while N. c. cristatus, though not 

 typical, is distributed over the northern portion of the State and 

 the pine barrens. But two specimens having the extremely long 

 pronotum are before us; both are females, one from Beatty, Penn- 

 sylvania, the other from Virginia; this form of the present race has 

 been named atavus by Blatchley. 



About Philadelphia this form is very occasional excepting upon 

 the barren serpentine outcrops, where in June adults may be found 

 in numbers. In July and September it was found very scarce in 

 the forest undergrowth of eastern North Carolina; at which former 

 time half of the specimens were in^the immature condition.
