t is one that has no bright colours and is not hairy ; such as 
^anthograpla. The reason for putting the larva in pyroligneous 
^ solution of alum is to harden the skin, so that it may not be 
too much ; and, if hairy, to prevent the hairs from falling out

ich ^^Bomlyx neustria, I generally starve it until it is nearly 
p and then kill it and take the inside out. In conclusion, I 
remark that some amount of patience is requisite to ensure 
Any further particulars or explanations that may be required

are 93 species enumerated, to which about a dozen have since 
added; these probably represent about 70 distinct species, as, in 
;quence of the insufficient descriptions of many of the earlier 
)rs, the synonymy has always been in a most tangled state. The 
descriptions are those of Loew and Egger, in the " Verhandlungen 
ool. bot. Verein." for 1S57 and I860, and I have adopted the three 
ps proposed by Loew, the first of which is distinguished by the 
nice of distinct hairs on the disc of the epistoma, which must not
