 ZYGJENINJ;, 

 ^ Genus ANATOLMIS. Packard. 



" Head of moderate size, broad and short. Occiput and epicranium 

 together, equal in length to the clypeus ; epicranium bilobate, much as 

 in Lycomorpha, with much the same proportions. The clypeus is very 

 broad, scutellate, just as broad as long, covered with broad flat scales 

 which converge towards the median line. Eyes small, hemispherical, 

 their diminished size adding to the breadth of the small clypeus between 

 them. Antennae situated nearly midway between the front edge and 

 the base of the head ; rather slender, with very short broad pectinations 

 equalling in length the joints, and covered densely, especially on the 

 sides, with stout hairs, and terminating in a single seta. Maxillae well 

 developed, longer than the head is broad. Palpi long, porrect, reaching 

 beyond the front ; third joint minute conical subacute, nearly continu- 

 ous with the second, which is not very broad. 



"Body slender, thorax, not much broader than abdomen ; wings 

 remarkably long and narrow. Primaries a little more than three times 

 as long as broad ; costa very straight, a little convex on the outer third; 

 apex rounded ; outer edge very convex, very short ; inner edge remark- 

 ably long, and nearly parallel with the costa, very straight, the usual 

 convexity near the insertion very slight. 



" Costal very near the margin, and infringing on the middle of the 

 first subcostal ; third subcostal of very equal length, 

 first curved towards the costa, the third shorter than 

 .^ _. ^ the first: fourth branched within its middle, enclos- 



'- ^^-i-~-^~J jng a narrow long triangular apical interspace; fifth, 



not removed from its nervule at its origin. Median, 

 nervules arise at the outer third of the wing. First and second are 

 united at their base ; third and fourth are equidistant from the second, 

 Submedian curve long, well marked, but no nervure. Very long in- 

 ternal nervnre. Fringe rather long, especially just below the apex. 



" Secondaries very long, twice as long as broad, narrow triangular, 

 hardly reaching to the tip of the abdomen. Apex much produced,
