segment 1 1 is very evident, showing that its supposed affinity 

 with Acro7iycta is confirmed by this curious and special 

 character. 



The arrangement of pale and dark segments may be made 

 more intelligible if arranged in this tabular form. Except in 

 ligustri, the head is always black, and the 2nd segment is pale, 

 except for the predominance of the dorsal plate and some dark 

 markings.

AcYonycia {Cuspidid) leporina. — This species and aceris differ 

 from the other Cuspidia in having very hairy larvae (in last skin). 

 The nature and disposition of the hairs, however, is such as 

 presents no similarity to the hairiness of the larvae of Viminia. 

 In Viminia, the hairs resemble those oi Arctia in being developed 

 in rosettes on the tubercles. In leporina, and to a great extent 

 in aceris, the tubercles actually disappear, and the hairs that 

 are developed are scattered over the general surface, and are, 

 in fact, a full development of the hair points that cover the 

 general surface in megacephala and strigosa (and others). Aceris 

 does, however, in one or two points, make an approach to 

 Viminia, probably, however, as a matter of parallel variation, 

 rather than by continuity of relationship. As to leporina, there 

 is only one point at all suggesting affinities to Viminia, closer 

 than those of the other Cuspidians, and that is that the newly 

 hatched larva has two hairs on the anterior trapezoidal 

 tubercles. On this point I must call attention to the circum-
