black jointed thoracic legs; no abdominal legs, but an anal prop-leg. The abdom- 
inal segments each with a traverse, oval-rounded, ventral, rough space forming a se- 
ries of creeping tubercles ; and in front on each segment is a transverse, oval, crescentic 
chitinous area bearing two piliferous tubercles ; the back of each segment divided 
into two ridges, each bearing a row of six sharp tubercles, bearing short hairs ; a 
single ventral row on each side of the ventral plate. Length, 7-10 mm . 
Pupa. — Body rather thick, white. Antennae passing around the bent knees (femero- 
tibial joints) of the first and second pair of legs, the end scarcely going beyond the 
middle of the body. Elytra with five or six rather deep longitudinal creases. The 
salient points of the body armed with piliferous warts. Abdominal tip square at the 
end, with a stout black spine projecting from each side. Length, 6 mm . 
Beetle.— Uniformly deep prussian blue, with greenish reflections on the head. An- 
tennal flagellum with fine whitish pubescence ; tibiae clothed with tawny hairs. 
Length, 5-6 mm . 
THE ALDER LEAF-ROLLER. 
(Gelechia oronella Walsingham.) 
While the leaves of the Alder are variously folded and rolled, per- 
haps the most striking leaf- roller is the above species, which occurred 
in Maine late in the summer, in August and the early part of Septem- 
ber. 
The little worm is amber colored, the body rather thick and cylindri- 
cal, but with no distinctive markings. One was observed which had 
sewed a portion of the edge of the leaf for half an inch in extent with 
four or five large white silk stitches. The moth, which appeared in the 
breeding cage May 4 of the following year, is described below. 
In another example, probably of this species, the end of the leaf was 
rolled up one and a half turns, and sewed with three broad strong silk 
stitches. On unrolling it the end of the leaf was found to be more or 
less eaten, the roll being gradually drawn in and made more perfect as 
the caterpillar consumes the tip of the leaf. It pupated September 18. 
Descriptive. — Larva. — Body rather thick, cyliudrical ; body aud head delicate 
amber-colored ; end of the body with quite long hairs, longer than the body is wide. 
Length 6 mm . 
Pupa.— Rather thick; mahogany-brown; length, 7 mm . 
Moth. — Palpi with the second joint moderately broad, scarcely more than twice as 
wide as the third joint, which is moderately broad and two-thirds as long as the sec- 
ond joint. Head and palpi whitish-gray ; second joint black externally ; third joint 
white, with two black rings. Fore wings of the usual shape ; white-gray ; at the base 
a black streak parallel to the costa; on the basal fourth of the wing is a pair of con- 
verging black spots; beyoud is a similar but thicker pair of black spots, and still be- 
yond another pair, one of the spots being situated on the costa ; four black costal spots 
towards the apex of the wing. Hind wings pale glistening gray. Expanse of wings, 
18 mm . I am indebted to Professor Fernald for the identification of this species. 
THE PINK-STRIPED WILLOW SPAN-WORM. 
( Deilinia variolaria Guen.) 
The caterpillar of this pretty moth is one of the commonest inch worms 
to be found on the Willow. 
The genus to which this caterpillar belongs was founded by Huebner 
for a moth referred by Guenee to Cabera. The species of Deilinia are
