15. Genus: Gasana Wkr. 
The question whether this genus really belongs to the Hepialid family cannot be decided here. I 
append it therefore with a reservation. body robust; no mouth-parts. Palpi porrect, strong, thickening, 
not projecting beyond the head. The 3rd joint conical. Antennae pectinated. Abdomen very long, project¬ 
ing beyond the hindwing by %, at the end with a long thick tuft and two posterior tufts rectangidar to the 
anal tuft. Legs stout, femora and tibiae slightly fringed. Hind tibiae with 4 long spurs. Wings narrow, distal 
margin convex, extremely oblique. The third lower vein is more than twice as far from the fourth as from 
the second to which it is very near. 
C. trochilioides Wkr. (77 c). blackish-blue. Antennae black. Thorax with a silvery spot in front trochilioi- 
on each side. Dorsal shield silvery white. Abdomen with a black anal tuft, lateral tuft ochreous, tips below 
pale golden. Feet copper-coloured. Forewing black with numerous dots of a steel gloss, under surface metallic 
blue, partly green. Hind wing vitreous and broadly margined with black. Length of body 10 lines (= 21 mm), 
of the wings 16 lines (= 33 mm). Aru Island. (The species was placed here by Pfitzxer. I only know 
the figure by Swixhoe, and according to this it may rather belong to the Cossidae [Gaede],
