ADYERTISEMENT. 



Xot only is our own, and the Lcpidopterou.s liiuna of other oountrio?, constantly rotciving 

 numerous additions, but inuuiuerable species of ali-eady described Lepidoptera, both native 

 and exotic, have never been figured, and as a consequent result are in very many instances 

 unknown to the student. Having, (hiring the course of over twenty years' study and collect- 

 ing, amassed a great quantity of material, I have concluded to endeavor to carry out my long- 

 cherished idea of publishing illustrations and descriptions of such undescribed species as I 

 may possess or have access to. The numljcr is immense, embracing niany uniques, types, and 

 other great rarities of the North American fauna; also to figure such species as have been 

 heretofore described but not figured. I do not intend to confine myself strictly to North 

 American species, but will illustrate new or unfigured species from anv other part of the 

 world — as the value of exotics for purposes of comparison, I think no one will dispute. 

 Inasmuch as nature, or nature's God, did not divide the earth into kingdoms, counties, or 

 townships, I don't see why we should do so in scientific matters. For my part, T con- 

 sider an example from Europe, Africa, or elsewhere, as interesting an object of study as 

 a North American one ; but, of course, as it happened to be my luck to be born on that 

 portion of the eartli's mud, stones, and water, called Ainorica, I will give jircccdenec to 

 the species of this country. It is my purpose to issue one number every month — each 

 number to have one plate ; but where tiie size of the species will admit, T will put as 

 many figures on one plate as possible. Where they are of small size, I will give some- 

 times as high as a dozen species on the same plate, but only less than tw" when the size 

 is very large — as in the first illustration, where one necessarily occupied tii<' whole page. 

 Of course U2)2)er and under surface will always be given, and both .'^cxes with larv;e and 

 stages of transformation whenever possible. The figures will all be drawn and colored by 

 myself from nature. My wish is to secure a sufficient number of subscribers, at as early 

 a date as possible, to pay the expenses of printing and paper. The hope of being even 

 in a small M'ay useful in this my favorite science will be more than sufficient reward for 

 my own trouble and labor. As soon as I can secure an ade<(uate number of subscribers, 

 I will add one other plate to each number, without increasing the i)rico — wliich is fifty 

 cenits per number. I will always give as complete technical description and history of 

 species as possible, also such observations or facts as I may deem of general interest to 

 the Entomologist. 



Trusting that the Entomological world, and friends of Science and Art generally, will 

 feel enough interest in my undertaking to send in their names and subscription price for 

 A. D. 1872, viz : six dollars, at as early a date as convenient, 



I am youi-s, truly,
