MCEKIS. — METEON. 557 



We have seen upwards of a dozen specimens of this well-marked species from 

 within our limits, agreeing accurately with the figures in Hiibner's work. In one of 

 the Chiriqui insects we notice three small subapical ochreous spots on the costal 

 margin near the apex, another in the cell, and three forming a faint oblique row 

 beyond the brand. We figure the fore wing of a male, to show the brand (Tab. C. fig. 1), 

 also the genitalia, for which latter, see Tab. C. fig. 2. 



2. Moeris hyagnis, sp. n. (Tab. C. fig. 3, a .) 



Alis fuscis, stigmate nigrescente : subtus ut supra, sed anticis angulum analem versus paulo pallidioribus, 

 puncto minuto subapicali, posticis quoque alio ad cellular finem, albidis ; corpore subtus coloris 

 ejusdem.

Our description is taken from a single worn male, and we have two females from the 

 same locality which may possibly belong to this species ; these latter have the outer 

 margins of the wings greyish beneath, otherwise they resemble the other sex. It is 

 very like Mnasicles hicetaon, but has a broader brand on the primaries and a shorter 

 and stouter terminal joint to the palpi. The very different coloration of the underside 

 distinguishes it at once from M. striga. For the genitalia of the male, see Tab. C. 

 fig. 3. 



METRON, gen. nov. 



The single small species referred to this genus, Pamphila chrysogastra, Butl. ( = P. fas- 

 ciata, Moschl., and Ilesperia goza, Hew.), a widely distributed Tropical- American 

 insect, is an isolated form, differing from most of its allies in the neuration of the 

 wings, and in the shape of the brand on the primaries of the male. The coloration is 

 also peculiar, the secondaries having a broad white fascia beneath, one other species 

 only, amongst the Central-American Pamphilinae, Metrocles leucogaster, coming very 

 near to it in this respect. 



The antenna? are half the length of the costa, and have a stout club, terminating in 

 along crook. The palpi are densely clothed with scales; the third joint is stout, 

 short, and bluntly conical. The primaries are produced at the tip, comparatively short, 

 the costa very slightly arched towards the base ; the cell is less than two-thirds the 

 length of the costa ; the upper discocellular is long and strongly oblique, the lower one 

 extremely short, the latter barely one-third the length of the third median segment ; 

 the lower radial is greatly depressed at the base ; the first branch arises from consider- 

 ably before the middle of the median nervure, the second not far from the lower angle 

 of the cell. The secondaries are produced at the anal angle ; the discocellulars are 

 very faint, the lower one very long and strongly oblique. The body is robust. The 

 middle tibia? are furnished with long spines, and the hind tibiae have two pairs of
