Wishing to comprife fuch information as may recommend our 

 Work, to a general Clafs of Readers, we are abfolutely compelled to 

 deviate from that uniform path which we at firft intended to purfue ; 

 by introducing the figures of fome Moths before we can procure their 

 larva; we promife this will rarely occur, except with Infects whofe 

 larva are unknown ; and the Author will fpare no expence, or trouble, 

 to attain even thofe : but, were he to refufe a place to the many valu-« 

 able fpecimens recently difcovered, it would be very difpleafing to 

 the greater part of his Subfcribers 5 therefore, as an invariable obfer- 

 vance of fuch intention, promifes only to exclude the moft rare of our 

 Infects, we cannot always indulge it: on t .is plan, in the firft Volume 

 we could neither have reprefented the Phal. Batis, Peach Bloffb?n^ as 

 the larva has only once been found ; or the Phal. Chrifternana, whofe 

 larva is unknown* : Thefe are Infects which few Cabinets in Eng- 

 land poflefs; hence the figures muft be very acceptable, and their 

 rarity a fufficient apology for their premature introduction. 



* The Caterpillars of a very fmall portion of minute Moths are known; 

 and many Species in the adult Mate are fo very rare, as to have efcaped the 

 attention of the molt acourate Entymologifts. Of the number which are 

 afcertained as natives, very .few are hitherto figured, or even defcribed.
