No. 6. — On the Larvae of the Higher Bomb gees {Agrotides 
Grote ). 
By Harrison G. I)yar. 
I have presented a preliminary synopsis of this lepidopterous super- 
family on larval characters under the term Noctuina in the Transac¬ 
tions of the New York academy of sciences (Yol. 14, p. 56-57) 
stating that abetter arrangement was to be desired. The present is 
an attempt in this direction. 
By accepting Mr. Grote’s recognition of the family Apatelidae and 
Mr. Schaus’s reference of Apatelodes to the Eupterotidae (to which 
T add all the hairy Notodontians), the arrangement can be materially 
simplified. The lower families do not require further remarks ; but 
I have some additional material in the higher ones. This is especially 
the case in the lvmantriid section, with which I now include the 
Lasiocampidae. I havm examined the larva in stage I of the hairy 
Notodontians, to be now referred to the Eupterotidae, several young 
larvae of Lasiocampidae, and have found a most interesting general¬ 
ized Lasiocampid, which exhibits true undegenerate warts in the 
last stage, the arrangement of which can be plainly made out. 
The conclusions are expressed in tabular form and in a genealog¬ 
ical tree, while some details are discussed in the special descriptions 
following. I begin here with the Drepanidae, which have the most 
highly sjiecialized development of setae of any of the simple haired 
Bombyces, and end with the Lasiocampidae, the most specialized 
family of the group. The old name Bombyces, or better Bomby- 
cides, must be used instead of Noctuina or Agrotides, since it 
appears that Bombyx belongs to this group and not with the 
Saturnians. 
A REVIEW OF TIIE SETAE OF THE BOMBYCIDES. 
In the majority of the species the setae are single, with small simple 
chitinous tubercles, and the normal arrangement (Psyche, vol. 7, p. 
253, fig. 1 for abdomen; Trans. N. Y. acad. sci., vol. 14, p. 50, fig. 2, 
for thorax), modified on the abdominal segments by the movement
