Psyche 
[Aug.-Oct. 
the forms with a minimum of dark have rather stronger punc- 
tuation. There seems no particular distinctive feature to this 
form. The Surinam examples are smaller and darker colored, 
only the sutural area being indefinitely lighter. 
Malacosoma bellum sp. nov. 
Medium sized, rufous, antennae, apex of tibiae and tarsi 
darkened, elytra closely finely punctate shining violet purple. 
Type cf, 9 Rio Janeiro, Brazil (Klages ?). Length 5-5^2 
mm. Bow. coll. 
Head with well marked transverse impression, with convex 
nearly smooth vertex, antennae moderate length, joints 2, 3 
equal or nearly so, 3 basal rufous; thorax transverse, smooth 
shining convex, almost without trace of depression or punctures, 
elytra parallel, impressed within the shoulder and very slightly 
at the suture below base, punctuation obsoletely seriate on the 
9 disk, the suture very narrowly cyaneous. I should have 
referred this form to dubia Oliv. if that did not call for smooth 
elytra. 
Malacosoma (Exora) simile sp. nov. 
Medium sized dull fulvous, antennae, 4 spots at base of 
elytra and 4 anteapical black 
Type 1 cf Caraca, Brazil. Bow. coll. Length mm. 
Head scarcely depressed between the eyes, vertex convex 
smooth, antennae (last 4 joints missing) 2, 3, very small, nearty 
equal, remainder elongate, thorax transverse, smooth, almost 
impunctate elytra very thickly evenly punctate like guttata, an 
elongate spot at the shoulder and a round one either side of the 
scutel, and 4 placed transversely just before the apex. Guttata 
is larger, has a black head and breast and light antennae, similis 
has black antennae and light head and breast. 
Malacosoma (Exora) octoguttatum sp. nov. 
Small, chestnut brown, antennae dark, elytra with four 
elongate spots at the base (2 each side) and four round spots 
transversely placed just behind the middle.
