Hepialus cemulus, Butl. A. M. N. H. (4) xx. p. 482 ; 111. Typ. 

 Lep. Het. pi. xxvii. fig. 8. 



Several specimens in Fryer's collection, among which are both 

 the forms described by Mr. Butler. I have examined these most 

 carefully, and endeavoured to find some trustworthy character that 

 would give specific distinction ; but have failed to discover anything 

 of the kind. Intermediates between the two forms are represented 

 in the series before me, and the range of variation is not nearly so 

 extensive as in some well-known species of the genus found in 

 Europe, H. velleda for example. 



Mr. Fryer, who appears to have had excellent opportunities of 

 deciding, was of opinion that H. cemulus and H. excrescens were 

 identical. In his Catalogue there is a note on the economy of the 

 species, which it may be interesting to give in extenso : — 



" Yokohama, very abundant ; it emerges late in the autumn ; 

 large specimens measuring 4^ to 5 inches in expanse; it is very 

 destructive, particularly to imported fruit-trees, in the stem of which 

 it burrows two years ; it is extremely prolific, the body of a full- 

 sized female is two inches long, filled with minute eggs, which it 

 scatters loosely about the tree it feeds on ; I have found it in almost 

 all trees except conifers ; it often attacks vines, and prefers to 

 burrow in the stem of a tree to which a wisteria or other climber is 

 .attached. The ichneumon that preys upon this insect is a most 

 .extraordinary one ; the body is short and oval and measures \ an 

 inch, but the ovipositor is y inches long. Expanse of wings Ig inch.''
