The foregoing is only a part of the true list oi llymenoptera, that may ultimately Ije 

 found in the county of Lancaster; but many of them have a wide range geograi»hically, 

 and may be found in nearly every State of the Union. The material of the comi)iler 

 was too meagre to furnish a comjilete list, or one that reflects the true state of entomo- 

 logical science in this department at the present day. It may .sen-e as an ai)pro.\ima- 

 tion to what Lancaster county contains, of this interesting order of inscct.s, only a few 

 spieces of which are known to belong to the destructives; and those chiefly conlinc them- 

 selves to the foliage of vegetation or are wood borers. The jjarasitic species, of which 

 there are many, may be regarded as the special friends of the human family, and their 

 study is therefore both interesting and useful.

This order includes the "Butterflies" and "Moths," and the name is derived fi-om 

 the two Greek words lepis a scale, and jUeron — a wing, or "scale-winged" insects. 

 The whole order may be brought more or less under the following characteristics.

 and under surfaces with minute colored scales, resembling dust or meal; eyts large and
