spurs. The primaries of the male have an inconspicuous treble brand : (1) an elongate 

 streak extending along the whole length of the second median segment, and widened 

 towards the base, so as to fill the angle between it and the origin of the first median 

 branch ; (2) a short longitudinal streak just below this ; (3) a still shorter piece in 

 front of the submedian nervure before the middle. The general shape of the wings is 

 like that of the species of Cobalus ; the body is comparatively robust ; the genitalia of 

 the male are very peculiarly formed.

This pretty little species has a wide range, extending from Mexico to the Amazon 

 region. It is very easily recognized by the broad whitish band on the secondaries 

 beneath, and by the form of the brand on the primaries. 



We have seen sixteen examples, ten of which are from within our limits. We 

 figure a male specimen from Bugaba ; also the fore wing, to show the position of the 

 brand (Tab. C. fig. 6), and the genitalia, for which latter, see Tab. C. fig. 7, 



METROCLES, gen. nov. 



The single species from Central America placed here is extremely like Metron 

 chrysogaster in general coloration, but differs from it in having a conspicuous and very 

 dissimilarly shaped brand on the primaries in the male, as well as in the neuration and 

 other particulars. Unfortunately, one specimen only has been seen, and that not our 

 own, so we are unable to figure the genitalia and other points of structure. 



The antennae are rather more than half the length of the costa, and have a stout 

 club, terminating in a long crook. (The palpi are broken off.) The primaries are 

 moderately produced, somewhat blunt at the tip, and arched on the costa towards the 

 base; the cell is less than two-thirds the length of the costa; the discocellulars are 

 oblique, the upper one more than twice the length of the lower ; the third median
