H. shurtleffii Pack. (164 c) is a small species, the d with black hindwings and black dusted forewings shurilefji 
with an indistinct marking shaped like a dog's head. The $ exhibits an even less distinct marking on the 
lustrous yellowish-brown forewing, while the hindwing is blackish. Expanse of wings: d 10—12, t 1 1 14 mm. 
Larva green with 2 yellow stripes which are connected by a red spot in the middle. Edge of frons smooth, with 
a yellow line. On oak and Ostrya. New Hampshire, Massachusetts, New York, District of Columbia. 
H. minuta Reak. (164 c) is also small, both sexes of the same colouring, the forewing lustrous brownish mhuda. 
yellow without any marking; hindwing blackish brown. Expanse of wings: d 10,6, $ 11,5 mm. Larva green. 
2 red lines intersecting in the middle; edge of frons with 2 horn-points, yellow. It lives on oak. Pennsylvania. 
The types got into the hands of H. Strecker who. by mistake, destroyed them as an undesired material. At 
present not one specimen of this species exists in collections, nor has anybody seen the larva in the last 40 years. 
Reakirt mentions 3 spurs on the hind tibiae of the imago. This is surely a mistake; I presume there are 
two: if there were 4. the species would have to be placed to Tortricidia Pack, with Kronaea Reak. as a synonym. 
2. Genus: Tortricidia Pack. 
Distinguished from the preceding genus by the presence of 2 pairs of spurs on the hind tibiae, from 
the following genera by short palpi barely reaching the vertex and a somewhat more projecting head, more¬ 
over by a longer and more pointed shape of the wings. Apex of forewing rounded. 
T. flexuosa Grt. (164 c). Forewing from dull ochreous to brownish, with most variable markings, with fie.mosa. 
a more or less distinct straight median line and a very convex exterior transverse line, more or less shaded 
with brown. If the latter forms a distinct dog's head marking, it is the form: — caesonia Grt. (164 c). Expanse caesonia. 
of wings: d 14—18, C 20—22 nun. The green larva is densely set with cavities, with 2 indistinctly shaded 
yellow lines, between them more or less red from a tiny spot to a broad band. It lives on oak. New York, 
Indiana, Virginia, North Carolina. 
T. pallida H.-Schaff. (164 c). Forewing brownish ochreous with a silky gloss, with irregular almost pallida. 
quite absent transverse lines. flavula H.-S. shows more distinct linear markings. Expanse of wings: llavula. 
d 10—15, $ 16—20 mm. The green larva is flattened with an irregularly shaped red meso-dorsal marking 
which may be very extensive. In late autumn on varioiis trees and shrubs. Massachusetts, New York. Mary¬ 
land, Virginia, North Carolina. 
T. testacea Pack. (164 c) has silky lustreus brownish ochreous wings with brown-striped veins; the tcstacea. 
easternmore form testacea exhibits an oblique brown shadow in the centre of the forewing, which is absent 
in the western form — crypta Dijar. Expanse of wings: d 14—16, $ 20—24 mm. Larva green, flattened with crypta. 
a small irregular red cross on the dorsum. It lives in spring on various trees and shrubs. New Hampshire, 
New York, Maryland; Manitoba, British Columbia, Colorado. 
3. Genus: Slossonella Dyar. 
This genus containing but one species is characterized by the very short palpi not reaching the vertex 
and by the very small retracted head. 
S. tenebrosa Dyar. Only the $ is known so far. Forewing dark brown with the usual blackish lines tenebrosa. 
of a dog's head shape, which, however, are only traceable. Hindwing black, fringe light. Expanse of wings: 
18 mm. 
4. Genus : l^itliacodes Pack. 
Mostly also small species characterized by the presence of two pairs of spurs on the hind tibiae and 
by somewhat longer palpi slightly projecting beyond the vertex. 
L. fasciola H.-Schaff. ( = divergens Wkr., belfragei Dyar). Forewing yellowish brown, with a white fasciola. 
transverse line which is widened in the middle somewhat like a spot and is provided with a tiny dent below 
it, with a purple brown shadow behind it; a fine blackish and bent exterior line. Hindwing more or less dense¬ 
ly dusted with black. laticlavia Clem, lacks the purple brown shadow behind the white line. Expanse of laiiclavia. 
wings: d 14—20, $ 20—22 mm. Larva green, stout and broadly rounded, ending quadrangular behind, indis¬ 
tinctly marked yellowish. It lives on many trees and shrubs. New York. Maryland, Virginia, North Carolina, 
Florida, Mississippi, Texas.
