vein stalked. 3 12 mm. Missouri. — The larval bag is cylindrical, ash-grey, 11 mm long, covered with fine rests 
of bark or lichens. On the trunks of apple and pear trees. According to Dyar also on Quercus marylandica. 
2. Genus ; Proclialia Barnes & Me. Dunn. 
Antennae of 3 bipectinate. Anterior tibiae with a long thorn. In the forewing all the veins are present, 
free, only 8 -f- 9 stalked, towards the inner margin no spur from the inner-marginal veins. Veins 4 and 5 of 
hindwing from the same base. Vein 8 not connected with the cell by a bar. 
P. pygniaea Barnes (169 b). Body and wings uniformly blackish brown, similar to Platoeceticus nigrita pygmaea. 
(169 d). Abdomen as long as hindwing. 12 l / 2 mm. Described according to 1 3 from Florida. - The larval 
bag is narrow, cylindrical, 12 mm long, spun with pieces of lichens. Common on trunks of orange trees, but 
the breeding yielded only a single 3- 
3. Genus: l>eiitlropsyclie Jones. 
Antennae of 3 bipectinate to the tips. No spurs or thorns on the tibiae. Wings rounded. Forewing 
with 11 veins, 8 and 9 from the same base, the others separately, no spur to the inner margin. Hindwing with 
7 veins all of which are separated, vein 8 sometimes with a bar to the cell. 
D. burrowsi Jones is of a feeble structure. Uniformly smoke-brown, body hairy. 12 mm. Described burrowsi. 
according to 3 33 from British Guiana. — The bag is 12 mm long, conical, the largest width above 3—4 mm, 
below 1 mm. It is presumably carried by the larva in an erect not pendent way. 
b) Subfamily Psychinae H.-Schdff. 
The two inner-marginal veins of the forewing despatch a single spur to the inner margin. The hind 
tibiae are shorter than the anterior ones. 
4. Genus: Cocliliotlieca Rmb. (Apterona Mill.) 
The genus contains tiny lepidoptera of a frail structure with broad wings clothed with hair. Forewing 
typically with 10 veins, hindwing with 7. The larval back of the European species is curved like a snail-shell 
and clad with sand. Only 1 species in America. 
C. fragilis Barnes A- McDunn. (169 b). Forewing with all the 10 veins arising at equal distances, only fragilis. 
veins 4 and 5 a little nearer together. Hindwing with 7 veins, veins 4 and 5 from the same base or stalked. 
Vein 8 connected with the cell by a bar. Antennae of 3 strongly pectinated, thorax thinly clad with long 
white hair. Wings blackish, semidiaphanous, long -haired. Abdomen short. 11 mm. 2 33 from Arizona. 
5. Genus: Psyche Schrk. 
All that is necessary has already been said about this genus in Vol. II. p. 361. Only one American 
species which, however, may also belong to Platoeceticus. 
Ps. watsoni Jones (169 b). Similar, but larger than Plat, gloveri Pack. (169 c). Antennae of 3 strongly watsoni. 
pectinated. Fore wing with 12 veins, 4 + 5 and 8 + 9 stalked, sometimes also 7+8 + 9. The hind wing has 
8 veins, 4 + 5 stalked or arising from the same base. Anterior tibiae without a thorn. Antennae black, wings 
brownish black, body delicate, little or not projecting beyond the hindwing. 15—20 mm. Haiti. — Larval 
bag 15—20 mm long, strongest in the middle, composed of grey silk, irregularly spun with small pieces of leaves 
and bark. 
Ps. bergi and Ps. burmeisteri Weyenbg. are quite irrecognizably described and figured, for which reason 
they have been passed over here. 
6. Genus : Euryeyttsartss Hmps. 
In the forewing of the type veins 7 and 8 + 9 arise from the upper cell-angle, vein 6 is absent in both wings. 
E. confederata Grt.db Bob. (169 b). Veins 8 + 9 of forewing on a very long stalk. The bar from vein confederata. 
8 to the cell on the hindwing is situate nearer to the cell than in the other species. Blackish brown, wings not 
diaphanous, broad. 15—20 mm. In the Southern States and as far as New York. — The bag is 15 mm long, 
longitudinally covered with projecting needle leaves. 
E. tracyi Jones (169 b). The antennae are larger and more broadly pectinated than in confederata, each iracyi. 
dent of the comb with a fine tuft at the tip. Body hairy, especially densely so on the thorax. Wings broad, 
forewing short, so much rounded that an apex or anal angle is not discernible. Veins 8 and 9 not or very shortly 
stalked. In the normally round hindwing the bar extends from vein 8 to the middle of the cell. Ground-colour
