Insects. 5377 



elbowed or thrown back on the thorax, always alike in both sexes ; 

 maxillary palpi frequently distinct. Body thin. Thorax short and 

 globular, more squamose than velvety. Abdomen long, squamose, 

 glossy and shining, nearly always conical and short in the male, 

 never garnished with a tuft in the female, in which it always termi- 

 nates in a point more or less abrupt. Tliorax often garnished with a 

 squamose or velvety plate. Legs thin, long, glossy, very rarely vel- 

 vety, anterior having the thigh and haunch long, nearly equal; tibia 

 more than half shorter; tarsi very long; the two other pair of legs 

 very long and silky, and extended beyond the abdomen. Wings 

 shining, often iridiscent or half- transparent, entire, never raised in 

 repose or folded round the body; superior wings always longer than 

 the inferior, marked with lines, of which the two median are constant, 

 but the subterminal almost always non-existent or scarcely indicated ; 

 inferior wings imperfectly developed, sharing often the marks and 

 colours of the superior. 



Nervulation. In the upper wings no areola; the subcostal has 

 six complete nervules, the 1', 2' and 1" always free, median quadrifid. 

 In the superior wings the costal is robust, nearly always bifid, and 

 giving birth to 2' and 3' ; the subcostal stretching only to the disco- 

 cellular, which it crosses in the form of the letter X, then reduced to a 

 very thin thread, very often atrophied before the base of the wing and 

 sometimes quite extinct ; median constantly quadrifid ; three free 

 nervures after it, submedian, intermedian, and the internal.
