ADYERTISEMENT. 



Not only is our own, and the Lcpidoptcroiis fauna of other countries, constantly receiving 

 numerous additions, but innumerable species of already descril:)ed Lepidoptcra, both native 

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

 unknown to the student. Having, during 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 uudescribed species as I 

 may possess or have access to. The number is immense, embracing many uniques, types, and 

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

 heretofoi'c described but not figured. I do not intend to confine mj'self strictly to North 

 American species, but will illustrate new or unfigured species from any 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 ray part, I 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 ray luck to be born on that 

 portion of the earth's mud, stones, and water, called America, I will give precedence to 

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

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

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

 times as high as a dozen species on the same plate, but only less tliau two A\hen the size 

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

 Of course ujiper and under surface will always be given, and both sexes with larvte 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 hojie of being even 

 in a small way 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 adequate number of subscribers, 

 I will add one other plate to each number, without increasing the ]iricc — which is fifty 

 cents per number. I will always give as complete technical descrijition 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 intei'est 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 yours, truly,
