A KEVISIO.N OF TIIK OKLTolD MOTJIS ^^MITH. 45 



subtciTiiiiKil line, which is I'nMjuciitly preceded by a dark Hue. Tlie 

 median lines are not threadlike, ai\' usually well marked, and obscured 

 only in very dark specimens. Yet withal thedifVerences are unsatisfac- 

 tory, and structural (diameters do uot help us mu(di. 



The forelegs are practically as in Z. marcidilinai, save that the 

 tioclianter is somewhat shorter and about oue-lburth the length of the 

 femur. The antenna' are somewhat shorter and stouter, and there is 

 often a third Joint fuinished with <i spinous process. Else I find no 

 notable ditlerences.

Eyes naked, large, globose. Front smooth, in perfect exami)les witli 

 a i)ointed tuft between the anteunie; but this is a variable and often 

 defective feature. Tongue moderate. Anteinue moderate in length, 

 arising from the vertex close to the coini)ouud eye, the basal joint 

 enlarged in the male, less prominent in the female. In the male the 

 antenna' are bipectinated, a single branch on each side of each Joint, 

 except that at the inner side, for one-third from base, the pectinations 

 are wanting. At this ])oint two or three joints bear specialized cor- 

 neous processes similar to those in Zcoiclognatha, and beyond it the 

 antenna' are normal. Jn the female the antennte are simple, with 

 .shght lateral ciliations, the ciliations apparently arising from alternate 

 joints only. The i)alpi are sickle-shaped, curving upward and dis- 

 tinctly exceeding the vertex, in essential character like Zundixjnatha. 

 Ocelli distinct, close to the compound eye, and also close to the base 

 of the antenna. The body is slight, untufted, the abdomen cylindrical, 

 exceeding the anal angles of the secondaries. Legs long, quite robust, 

 the posterior being most developed and much the longest, without 

 armature other than tlie usual spurs of middle and posterior pairs. 



In the male the anterior tibia' are remarkably modified. All the 

 l>arts are elongated and tufted, the trochanter is excessively developed 

 ill all the species, the tibia is an al.'ortion, and the tarsi are obsolete in 

 some si)ecies. The tibial process is the most i)rominent part of the leg 

 and covers a mass of specialized, blackish scales. 



The wings are moderate and proi)oitionate, the ])riniaries. exccjit in 

 H. orcifcralis. trigonate, with marked Or even pointed apices; in the 

 latter subefjual, with obtuse or rounded apex.
