treble brand formed thus : (1) an oblique curved streak extending from near the distal 

 end of the second median segment to the first median branch at some distance from its 

 point of origin ; (2) a short, slightly oblique, piece just below this ; (3) another oblique 

 piece extending forward from the submedian nervure at some distance before the 

 middle.

Bab. Mexico, Atoyac (//. H. Smith). 



We have ten specimens of this species, including both sexes, all collected by 

 Mr. Smith at Atoyac. Dr. Staudinger has sent us a male very like it, from Herrich- 

 Schaffer's collection, under the name of Goniloba degener ; but this insect has a very 

 distinct hyaline spot towards the apex of the primaries, and these wings are without the 

 whitish submedian streak beneath, and the brand also is somewhat differently shaped. 

 In (E. pyste there is sometimes a minute white spot towards the apex of the primaries! 

 For the genitalia of the male, see Tab. XCVIII. fig. 41. 



MUCIA, gen. nov. 



The widely-distributed Tropical-American insect referred to this genus has exactly 

 the facies of a Cobalus, but the treble brand on the primaries in the male separates it 

 at once. This last-mentioned character brings it near Onophas, (Eonus, Perimeles 

 Lerema, &c, but the form of the brand is a little different from that of the species 

 of all these genera, and the genitalia of the male also. We have one or two unnamed 

 South-American forms in our collection that probably belong here, but we have not as 

 yet seen males of them. 



The antenna; are about half the length of the costa, and have a rather short stout 

 club, terminating in a long crook. The third joint of the palpi is very short, stout, and 

 bluntly conical. The primaries are moderately long, somewhat pointed at the tip the 

 costa arched at the base ; the discocellnlars are oblique, the upper one more than twice 

 the length of the lower; the lower radial is strongly depressed at the base; the first 

 branch arises from the middle of the median nervure, the second at some distance 

 before the lower angle of the cell. The secondaries are a little produced at the anal 

 angle; the discocellulars are oblique, the lower one distinct. The body is robust 

 The middle tibiae are spined, and the hind tibue have two pairs of spurs The 

 primaries of the male have a narrow, curved, oblique, interrupted brand formed of
