with hairs above. Forewings elongate, rather narrow, costa in 

 male simple, moderately arched, hindmargin rather strongly 

 sinuate below apex. Hindwings elongate, broader than fore- 

 wings. Forewings with veins 7 and 8 stalked, 7 running to 

 hindmargin, secondary cell indicated or distinct. Hindwings 

 with veins 3 and 4 stalked, 5 closely approximated to 4 at base, 

 6 and 7 stalked. 



Larva sixteen-legged, mining in blotches in leaves, or feeding 

 in spun-up shoots. 



This genus may be regarded as the type of a small group, to 

 which Rhopobota and Holocola also belong, related in general 

 characters to the group of Grapholitha (particularly to the genus 

 PhoxopteryxJ, but distinguished by the stalking of veins 7 and 8 

 of forewings. The same character suffices to separate it from 

 the group of Strepsiceros, between which and the group of 

 Grapholitha it is apparently intermediate. Palceobia differs from 

 Holocola by the absence of a costal fold in male, and from 

 Rhopobota by the dense tuft of palpi. Superficially it much 

 resembles Phoxopteryx in form, colour, and marking, but the apex 

 of forewings is never actually falcate. The mining habit of the 

 larva of at least one species is very curious, and unparalleled 

 among the Tortricina. 



The genus is probably rather numerously represented in 

 Australia ; I am acquainted with nine species, which may be 

 tabulated as follows : 

 A. Forewings whitish, with dark grey and 



ferruginous markings ; apex strongly 



produced. 



1. Anterior half of costa whitish. 



a. Central fascia distinct .. .. ..3. volutana. 



b. Central fascia merged with costal spot. . 1. anguillana. 



2. Anterior half of costa dark ferruginous. 



a. Costa beyond middle whitish . . . .4. erythrana. 



b. Costa beynd middle dark ferruginous. .2. infectana.
