This insect has been mentioned in my reports, but it has received no 

 extended notice, although inquiries have frequently been made of it by 

 letter and in person. Personal inquiries have uniformly been met by 

 presenting the excellent figures and account given by Professor Riley 

 in the American Entomologist, for December, 1868. The figures of 

 that article are herewith given from electrotypes obtained from Pro- 

 fessor Riley. For another paper upon the insect from the same 

 author, but essentially the same, the reader, may refer, if more con- 

 venient, to the Fifth Missouri Report. It may be noted here that in 

 each of these the eggs of the insect are erroneously figured, as was 

 subsequently learned, and for their correct representation and descrip- 

 tion, the Ninth Missouri Report may be si;en, where, also, the young 

 larva is for the first time described and figured. 



References to other writings on this insect are given in the above 

 bibliography, and as some of them, at least, may be conveniently referred 

 to by tho-»e who would like to know more of its interesting habits and 

 transformations, it is thought not desirable to embody them in a general 

 account for the present report.
