42 PACKARD; NOTES ON THE 



wing. First subcostal arises very near the upper discal ; second 

 subcostal arises a little beyond the middle of the first subcostal; 

 third subcostal is short, and arises a little beyond the middle 

 of the distance between the apex of the wing and the origin of 

 the upper discal nervule. The fourth subcostal branches off 

 very near the apex, and is very short, being but one fourth as 

 long as the fifth subcostal, which last arises at a less angle from 

 its nervure than in Ctenucha. The discal nervules are mucb 

 more curved inwards than in Ctenucha. The median beyond 

 where it throws off its fourth median is bent upwards exactly 

 parallel with the costa. Though longer, the nervules are thrown 

 off from the nervure much as in Ctenucha, but the distance be- 

 tween the origins of the third and fourth median is proportion- 

 ally greater than in Ctenucha. 



Secondaries not quite half as broad as they are long, being 

 much produced towards the apex, and behind reaching to the basal 

 third of the abdomen. Costa straight, convex near the base. 

 Apex acute. Outer edge nearly three times as long as the 

 inner; straight on the outer half of its length, but becofbirig a 

 little convex towards the internal angle,' which i? well rounded, 

 while the inner edge itself is straight. The subcostal goes re- 

 markably straight to the apex where it curves a little down- 

 wards ; it throws off a single straight nervule a little within the 

 outer third of its length. The upper discal is a third longer 

 than the lower, which is the stouter of the two The three 

 first medians are very short, one third as long as the whole me- 

 dian, the third shortest. First curved, second and third straight, 

 fourth curved downwards near its origin. The submedian is 

 obsolete at its basal third, the terminal portion being more like 

 a nervure than a mere fold. It is close to the internal and re- 

 mote from the median. Internal straight, cutting off a large 

 triangular area comprising the internal angle. 



Legs rather long, slender, thinly scaled, the spines minute 

 and weak. The hind legs differ from Ctenucha in being much 

 slenderer not at all swollen. There are the same proportions 

 in the length of the joints. 



Abdomen broad, and acutely pointed at the tip in both sexes, 

 with slight lateral tufts along the sides. The female tip is more 

 obtuse than in the male, thus approaching female Procris with its 

 truncated tips, more than Ctenucha with its simple pointed tip. 

 The genitals are simple and concealed within the eighth ring of 

 the abdomen. There is apparent a tergal piece, and a sternal
