however, is C. annus, the outline of the distal end of the harpes being very similar in 

 both cases.

Concerning this name there cannot be much doubt, for Mr. Butler tells us that the 

 Fabrician type is still in the Banksian collection in the British Museum, and with it 

 he identified specimens collected by Bates at Para. We have several examples from 

 the last-named source, one of which is marked by Bates as referable to C. zarew, 

 Hiibner, a name we are inclined to think synonymous with C. aunus, though other 

 authorities, including Plotz, keep them distinct. 



C. aunus, as we understand it, differs from C. nets in having a more definite band to 

 the primaries, the sides of which are less undulating ; the apical margin of the second- 

 aries and the fringe adjoining are always distinctly white. 



C. aunus is exceedingly common in Eastern Mexico, but we have not seen specimens 

 from the western side of the mountains. In Guatemala, however, it occurs in the 

 mountains sloping towards the Pacific, as well as in the Atlantic lowlands. 



The male genitalia resemble those of C. neis, so far as the tegumen and scaphium 

 are concerned : the harpes have the ventral edge produced into a point ; there is a 

 deep fissure on the dorsal edge, beyond which is an angular lobe, and the continuation 

 of the edge is irregularly serrate to the point. (See Tab. LXXX. fig. 4.) 



5. Cecropterus capys, sp. n. (Tab. LXXX. figg. 5, 6, 7 s .) 



Alis fuscis unicoloribus ; anticis fascia mediana a costa ad angulum analem venis (praeter subcostalem fuscum)

 posticis unicoloribus, ciliis ab angulo apicali usque ad venam medianam secundum albis : subtus ut supra
