have an undetermined species from Colorado Springs.

 O. princeps Casey. Colorado, Casey. 



COCCINELLID^. 



The arrangement of this family follows Casey's recent revision as far as 

 possible, though of course it is out of the question to correlate the old rec- 

 ords with his arrangement in every case. It seems too, that Major Casey 

 had very little material from Colorado before him, so that we are left with- 

 out a clue as to the disposition he would have made of doubtful or osculant 

 forms. For the present it seems unnecessary to make comments on the 

 status of some of the new names proposed, as more than one opinion may 

 easily exist regarding the separation of certain races and varieties. The 

 trinomial system seems destined to prevail in Entomology, as it has already 

 done in some of the kindred sciences, and most of the names will probably 

 be perpetuated in some form, even if a succeeding monographer degrades 

 them from specific rank.
