DYAR : LARVAE OF THE HIGHER BOMBYCES. 
135 
on the thorax two warts above the stigmatal wart in line transversely, 
the upper with two hairs (ia + ib), the lower with one (iia), stigmatal 
wart with two hairs (iv 4- v), iii situated behind it. Subventral 
wart with two hairs. The species of Utetheisa have the same 
structure. 
Coscinia striata, Linn. 
Abdominal warts normal; on thorax iib and iii represented by 
small, but distinct warts, iib bearing more than one hair. 
Callimorpha dominula , Euplagia quadripunctaria Poda, (= Cal- 
limorpha hero ), and Eyprepia pudica are in the same condition. 
Seirarctia echo, S. & A. 
I am indebted to Mrs. A. T. Slosson for an example of this larva. 
Warts as above, but iib on thorax represented by a single seta; 
wart iii in line longitudinally with iv 4- v. 
Cycnia egle , Estigmene acraea , and Halisidota tesselaris are in 
the same condition. 
Pyrrharctia isabella, S. & A. 
Wart iib on thorax absent, wart iii very small; otherwise the same. 
Sp>ilosoma virginica , Cycnia tenera (kindly given me by Mr. 
H. H. Lyman), Arctia villicci L., Ehyparia purpurata L., and 
Hyphoraia aulica L. have the same structure. 
Halisidota maculata, Harris. 
Both iib and iii absent on thorax; wart iv on abdomen small. 
JSFemeophila plantaginis comes here in respect to thoracic 
structure. 
It will be noticed that the Phaegopterinae are mixed with the 
Arctiinae in this review; the subfamily characters are not found in 
the thoracic warts, but in the reduction of iv on abdomen and the 
development of hair tufts and pencils. 
Family Nolidae. 
I am much indebted to I)r. T. A. Chapman for examples of stage 
I of Nola cucullatella. The larvae exhibit a primitive first stage with 
large single setae from unusually large bases, so that i and ii are 
contiguous as are also iv and v. The thorax is normal. It appears 
as if tubercles i and ii formed a single wart and iv and valso a single 
one. The ultimate arrangement is the same as in some Lymantriidae, 
and is therefore not unparalleled in the superfamily, but the method 
of formation is unique. This method of consolidation is characteristic
