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 Infe£ls 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 ; therefore, as an invariable obfer- 

 vance of fuch intention, promiles oaly to exclude the moft rare of our 

 Infe61:s, we cannot always indulge it: on tiis plan, in the firft Volume 

 we could neither have reprefented the Phal. Batis, Peach Blojfojn^ as 

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

 larva is unknown*; Thefe are Infefts which few Cabinets in Eng- 

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

 rarity a fufficient apology for their premature introduclion. 



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

 and many Species in the aault ftate are fo yery rare, as to have efcaped the 

 attention of the mo(t accurate Entymologifts. Of the number which arc 

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