LEPIDOPTERA HETEROCERA. 1817 



Alavona INTERMEDIELLA. 



Mas. Cinerea, fasco conspersa ; palpi oblique ascendentes, arti- 

 culo 3o lanceolato 2i dimidio breviore ; ales anticce nigricante 

 subreticulata, fascia media fusca costam versus valde dilatata, 

 guttis cos/alibus duabusque subcostalibus niyricantibus. 



Male. Cinereous, brown-speckled. Palpi obliquely ascending, 

 not rising so high as the vertex; third joint lanceolate, less than 

 half the length of the second. Antennas rather broadly pectinated. 

 Fore wings slightly. reticulated with blackish ; a brown middle band, 

 which is much dilated and widely excavated towards the costa; 

 several blackish dots along the costa and two in the excavated part 

 of the band. Length of the body 6 lines; of the wings 10 lines. 



It is very nearly allied to the preceding species, but may be 

 distinguished by the different arrangement of the reticulation of 

 the fore wings.

Alavona cossinella. 



Mas. Albida ; caput et thorax fasco conspersa ; palpi caput sat 

 superantes, articulo So lanceolato 2i dimidio non breviore ; 

 abdomen pallide cinereum, alas posticas dimidio super ans ; 

 alee anticce strigis duabus postmediis longitudinalibus e atomis 

 fuscis, strigulis marginalibas fuscis ; posticce pallide cinerea. 



Male. Whitish. Head and thorax brown-speckled. Palpi 

 porrect, extending rather beyond the head; third joint lanceolate, 

 about half the length of the second. Antennae rather broadly pec- 

 tinated. Abdomen pale cinereous, extending for half its length 

 beyond the hind wings; apical tuft large. Legs stout; spurs very 

 long. Fore wings rounded at the tips, very thinly brown-speckled, 

 excepting two broad postmedial longitudinal streaks where the 

 speckles are numerous ; costa with brown subquadrate marks ; exte- 

 rior border with short brown streaks, which extend over the fringe. 

 Hind wings pale cinereous. Length of the body 4 J lines; of the 

 wings 12 lines. 



It agrees with A. cossusella in structure, but may be distin- 

 guished by the different markings of the fore wings and by its much 

 smaller size.
