EIJTYCHIDE. 545 



terminating in a long crook. The palpi have the third joint very short and bluntly 

 conical. The primaries are moderately elongate and pointed at the tip in the male 

 (except in E. cingulicornis), blunter in the female ; the cell is less than two-thirds the 

 length of the costa ; the discocellulars are very oblique, the upper one about twice the 

 length of the lower, the latter slightly shorter than the third median segment ; the 

 lower radial is depressed at the base ; the first branch arises before the middle of 

 the median nervure, the second near the lower angle of the cell. The secondaries 

 are produced at the anal angle ; the discocellulars are faint and very oblique. The 

 middle tibia} are conspicuously spined, and the hind tibiae have two pairs of spurs. 

 The body is robust. The primaries of the male have a conspicuous treble brand, as 

 described above, and the secondaries in this sex have long hairs on the upper edge of 

 the abdominal fold. 



The genitalia of the males of the six species dissected show considerable divergence 

 in form, as may be seen by a reference to our Plate. In E. cingulicornis the antennas 

 are more elongate than in the other species we refer to the genus, and the primaries are 



also blunter at the tip. 



The brand is greatly developed in E. midia, E. ochus, E. lycortas, E. achelous, and 

 E. umber, moderately so in the other species; in E. achelous the lower arm of the 

 upper > -shaped piece is very short.

Our collection contains a long series of this well-marked species, including eight from 



within our limits. Southern specimens differ slightly in having two small spots, instead 



of one near the apex of the primaries, and sometimes another in the cell, and in the 



absence of the two minute spots on the secondaries above. We figure a male insect 



from Yzabal; also the fore wing, to show the position of the brand (Tab. XCIX. fig. 8), 



and the genitalia, for which latter see Tab. XCIX. fig. 9.
