Our Zebu Prominent, or, as the Aurelians call it, the fmall IroK 

 Prominent, is extremely fcarce. It was discovered in the larva ftate 

 upon the oak : in the month of September it went into the ground 



and became a pupa; the moth appeared in June following. 



This infect differs from the Fabrician Bombyx Dromedarius, or 

 what is termed with us the Iron Prominent in feveral refpects, though 

 at the lint view it feems to bear a very ftrong refemblance to that 

 fpecies. We object to the trivial Englifli name of fmall Iron Pro- 

 minent, becaufe it is only applicable, in a partial degree, to the infe6t. 

 Our Zebu Prominent is certainly fmaller than the infect known 

 in this country by the name of Iron Prominent, but this is not in- 

 variably the cafe. We have fean the male of the Iron Prominent of a 

 fize nearly, if not entirely, as diminutive as our fpecimens of the Zebu 

 Prominent; and if we may rely on the accuracy of the figures of the 

 latter in the works of Em ft, the Bombyx Dromedarius is not an infect 

 of much fuperior magnitude. We may truly infer from the figures 

 above mentioned, that the diminutive fize of our Zebu is no crite- 

 rion of the fpecies. 



A decided difference in point of colour, and in fome other parti- 

 culars, prevails between the two infe6ts. In Bombyx Dromedarius 

 the colour of the fuperior wings is fuscous molt delicately fpecklcd, 

 us it appears on clofe infpection, with grey ; the fpots of a deep 

 rusty-hon colour, and the denticulated bands acrofs the wings whitifh,
