 all forms wliose main distrihution is far to tlie south, find in soutli-

It is not strange, tlieret'ore, that we find, living with those plants 

 and animals, a iiumhei- of ()rlh()})tera whose range has heretofore 

 been, thouglit to be conliiUMl to the region mapped by Merriam a* the 

 "Lower Austral." Thirty-two of the s])ecies listed in the preceding 

 catalogue, or 'l\A\ piT cent, of the total, may be classed as southern 

 forms. Thev are as follows:

Of tile species listed, ^^Idi/iiiomanlis caroUna (L.), Camptonolus 

 ctiro/iiirnsls ((iers.), i^i/rbtila (i<liiiirabilis (\'h\.) and Ororharis sallalor 

 rill, have been taken in small nund)evs as far north as ^tarion 

 ('i)unty; all the others only south of the line mentioned as forming 

 the northern border of the Lower Austral, it will be noted that this 

 line eorres])onds a]i])ro.\imately with the southern border of the gla- 

 cial inxasion of Indiana, and it is more than probable that tlie an- 

 cestors of many of these southern forms existed in southern Indiana 

 in ])rcglacial times, when the clinuitc was much warmer than now. 

 .\s W'elistei' has recently pointed out*, it is also probable that some of 

 these Orthoplera, as well as a nund)i'r of those si)ecies inhal)iting the 

 entire' State, advanced into the State from the south as fast as it was 

 uncovered hv the recedinu' ice.
