238 Mr. Warren on the Pyralidina collected 



ignitalis, Wlk., from Ega, Hi/pena dbrasalis, Wlk., from 

 Mexico, and Hypena illapsalis, Wlk., from Para, belong; 

 but the palpi are much shorter and simpler, and the 

 colouring and markings wholly different. 



14. Paramacna arnea. 



Phalcena-Geomctra arnea, Cram., Pap. Exot., i., p. 59, 

 pi. 36, fig. G. 



Fore wing pale green, with the costa broadly dull purplish 

 brown, and a blotch of the same colour occupying the costal half 

 of the central area to below the median vein ; two obscure, brown, 

 transverse lines, also extending the same distance below the 

 median vein, the first before the middle at about one-fourth of the 

 costa, the second starting from the middle of the costa, and run- 

 ning outwardly in a series of curves, concave outwardly between 

 each nervure, showing more plainly in its lower part, where it 

 traverses a pale ochreous blotch which lies obliquely below the end 

 of the cell, and is bounded by a diffuse, curved, brown shade ; 

 reniform stigma distinct, brown ; a brownish shade along the inner 

 margin in the centre ; fringe greenish. Hind wing and fringes 

 silky ochreous, with a narrow brownish shading before the fringes. 

 Head, thorax, and palpi pale greenish ; terminal joint of palpi 

 brownish ; abdomen ochreous. Under side glossy ochreous, the 

 darker tints of the fore wing showing through ; a fringe of long 

 silky hairs along the median vein of the fore wing. Expanse of 

 wings, 36 mm.

In a note to the figure of Botys (?) linalis, Felder, its 

 close affinity to Phdcena arnea, Cram., is mentioned, 

 and the remark added that perhaps it was really a 

 specimen of that insect, of which the original green 

 colouring had faded, as a result of damp. Felder's 

 example was, like the present, from the Amazons. It is 

 possible that in some cases the violet-brown tinge over- 

 powers the green. At any rate, if the two are separate 

 species, they are very closely related ; but we must wait 

 for a larger number of specimens before a really satis- 

 factory conclusion can bo arrived at. 



AZAMOEID^. 

 Under this family I include all the genera, the species 

 of which are characterised by a peculiar, membranous, 

 scale-covered pouch, which occurs near the base of the
