DYAR: LARVAE OF THE HIGHER BOMBYCES.

others. The two lower are rudimentary, and in the adult larva only 
three warts persist, corresponding probably to ia+ib, iv-f-v, and vi. 
The figure (drawn with the camera) shows a side view of an abdomi¬ 
nal segment and a dorsal view of the first two thoracic segments. 
All the warts are shown, as the lower ones project enough to come 
into view. The drawings are in the same scale (x35), showing the 
considerable flattening of the larva. 
Staudingeria 1 vandalicia, Mill. 
Warts large and distinct, discolorous (red while the body is black), 
not obscured by the abundant secondary hairs. On the abdomen i 
and ii are large, elongate transversely, iii more rounded, iv and v in 
line below the spiracle, vi moderate, leg plate pale. On thorax 
three warts above stigmatal wart, the two upper in line longitudi¬ 
nally, large, equal, elongate transversely, the third wart more 
rounded ; stigmatal and subventral warts smaller. 
This arrangement is exactly that of the first stage just illustrated. 
The curious larva has but little of the appearance of the modern 
Lasiocampidae. Its abundant rather stiff hairs and conspicuous warts 
give it the appearance of some Arctian. We may regard it as a sort 
of living fossil, preserved by the degeneracy of the adults for the 
edification of students of the nineteenth century. 
The relations of the families of the Bombycides which I deduce 
from the examples here cited, as well as others, may be expressed as 
follows in the form of a genealogical tree. The round spots (•) 
1 Up to the date of Kirby’s catalogue at least, nothing has been published on the moth 
of this species. Kirby places the name under Albarracina with a mark of doubt, evi¬ 
dently because of Staudinger’s statement: “ Uebrigens lialte icli es nicht fur ganz 
unwahrscheinlich, dass die . . . Raupe, die Milliere beschrieben hat, zu dieser (Albarra¬ 
cina) Korbi gelibrt.” However this supposition seems to have been unfounded, for I 
have received from Dr. Staudinger the moths of vandalicia, the female wingless and 
neither corresponding to the description of A. korbi. I propose therefore the above 
generic term for the species, as the wingless female will separate it from all the 
other Lasiocampid genera known to me. The male has the following characters: — 
Primaries 12 veined; median 4-branched, vein 2 arising very near the base, 3-5 close 
together, cell open, 6 from the apex, 7-8 stalked, 9-10 stalked. Secondaries with one 
internal vein, median 4-branched, 2 near the base, 3-5 from nearly the same point, cell 
open, 6-7 from the apex, 8 from the end of a very small intercostal cell at base; a distinct 
curved humeral vein in the lobe; no frenulum. Antennae bipectinated, palpi short, 
dependent. The moth is light gray with a blackish median shade on primaries spread¬ 
ing toward the base and reappearing faintly at apex, covering also the head and anterior 
part of thorax; darker gray below, mixed with whitish scales with a curved pale mesial 
band on secondaries. Antennae ocherous. Expanse 28 mm. Female wingless, uni¬ 
formly gray, the abdomen scantily clothed with hair. A curious trifid prominence, 
concave below, on the front of the head, much larger than in the male.
