46 PACKARD. NOTES ON THE 



bilobate, much as in Lycomorpha, with much the same propor- 

 tions. 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 broad clypeus between them. An- 

 tennas situated nearly midway between the front edge and the 

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

 tions, equalling in length the joints, and covered densely, espe- 

 cially on the sides, with stout hairs, and terminating in a single 

 seta. Maxillse well developed, longer than the head is broad. 

 Palpi long porrect, reaching beyond the front : third joint min- 

 ute conical subacute, nearly continuous 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 con- 

 vex on the outer third ; apex rounded ; outer edge very convex, 

 very short ; inner edgs remarkably long, and nearly parallel 

 with the costa, very straight, the usual convexity near the in- 

 sertion very slight. 



Costal very near the margin and impinging on the middle of 

 the first subcostal ; third subcostal of very equal length, first 

 curved towards the costa, the third shorter than first ; fourth 

 branched within its middle, enclosing a narrow long triangular 

 apical interspace; fifth, not removed from its nervule at its ori- 

 gin. 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 mark- 

 ed, but no nervure. Very long internal nervure. Fringe 

 rather long, especially just below the apex. 



Secondaries very long, twice as long as broad, narrow trian- 

 gular, hardly reaching to tip of abdomen. Apex much produ- 

 ced, though obtuse. Costa very straight, outer edge very long, 

 remarkably straight , internal angle rectangular not reaching 

 much beyond the base of the anal tuft. 



Subcostal subdivides near the outer fourth of the wing ; first 

 and second median very short, nearly parallel ; third, very re- 

 mote but of the same length. 



Legs long and slender, finely scaled. Hind tibial spurs very 

 small unequal acute, inner pair very remote, and half as large 

 as the terminal pair. Tip of abdomen provided with large anal 

 valves, of unusual size, being laterally broad lanceolate.
