SATYRINAE: NEONYMPHA PIIOCION. 209 



curve of its last branch ; first median nervule originating somewhat t'lu'ther from the 

 base of the wing tlian the base of the second subcostal nervule. 



Androconia (46:4) exceedingly slender, twenty times as long as broad, tapering 

 from the rounded base with great regularity over the basal third, and then continuing 

 as a slender uniform thread to the tip, which is delicately feathered for a distance 

 equal to the basal width of the scale. 



Fore legs exceedingly small, cylindrical, the tibiae more than one-third the length of 

 the hind til)iae; fore tarsi one-quarter the length of the tibiae, either apparently con- 

 sisting of a single joint, the apical two-fifths of which tapers considerably and is 

 wholly unarmed but for a minute apical peg ((J) ; or composed of five joints, of which 

 the first is from two to three times longer than the rest together, they decreasing in 

 size regularly, and all but the last furnished at the tip , beneath, with comparatively large, 

 long and slender, tapering spines ( ? ) ; leg otherwise wholly unarmed excepting by 

 long hairs, which scarcely diverge from the leg; other legs compressed; middle tibiae 

 tive-sixths the length of the hind tibiae, both furnished with a lateral row of short, 

 slender, not very frequent spines upon the under surface, the apical ones produced to 

 long and slender spurs. First joint of tarsi as long as the rest together, these subequal ; 

 joints covered profusely beneath with small, slender spines, the apical ones of the 

 lateral row a very little stouter than the others ; claws slender, strongly and regularly 

 curved, a little compressed, delicately pointed; pulvillus minute, transversely oval; 

 paronychia consisting of two fringed members, the upper slender, as long as the claw, 

 straiglit, tapering in its apical half to a point, the lower broad at base, subtriangular, 

 incurved, the tip produced and pointed. 



Male abdominal appendages : upper organ rather small, with the sides of the centrum 

 straight but scarcely compressed, separated from the hook by a rather deep sulcation; 

 hook considerably longer than the centrum, bent downward a little, nearly straight, 

 strongly compressed above, below expanding into an oval appressed leaf, the tip 

 pointed ; sides of the centrum furnished near the middle of their posterior edge with a 

 single, long and very slender, sinuate, backward directed appendage. Clasps stout 

 and buUate, about three times as long as broad, the basal two-thirds bi'oad, but taper- 

 ing apically, the apical third slender, equal and hooked at the tip. 



Egg. Nearly spheroidal, the height and v\4dth about equal, the top very slightly 

 depressed, and the lower portions of the sides a little inflated. Surface covered -with 

 reticulations, forming small, irregular, hexagonal cells, largest on the upper half, and 

 reduced in the micropyle to a delicate, raised tracery of lines forming similar but much 

 smaller cells. 



Caterpillar at birth. Head subrotund, twice as broad as the middle of the body, 

 broadest below, each hemisphere surmounted by a globular tubercle, and midway 

 between it and the ocellar field a smaller pyramidal tubercle ; each of these and a few 

 still smaller papillae 'support a simple hair half as long as the width of the head, the 

 coronal tubercles with two ; triangle large and high. Body cylindrical, slightly 

 largest in the middle, the last segment slightly forked; papillae pyramidal, arranged 

 on the abdominal segments in laterodorsal anterior, supralateral posterior, stigmatal 

 anterior, and ventrostigmatal anterior series, one to a segment in each row; on the 

 thoracic segments these series are shifted to a laterodorsal anterior, infralateral ante- 

 rior, suprastigmatal central, and infrastigmatal series, one to a segment in each, except- 

 ing the infralateral where there are two close together, the hairs in this case diverging 

 and one longer than the other. All the papillae, including those of the first thoracic 

 segment, support almost perfectly straight, but slightly curved, club-tipped hairs 

 (86 : 40) , nearly as long as the height of the body ; spiracles lenticular. 



Mature caterpillar. Head rather small, full, deepest in middle and two-thirds as 

 deep as high, well rounded in every direction except that it is angulate above laterally, 

 the angles slightly produced, almost forming a tubercle; face broadest just below the 

 middle, and narrowing more above than below, the cheeks very full; studded every- 

 where with crowded papillae, which are larger and more prominent on the upper than 

 the lower half. Triangle reaching nearly the middle of the upper half of the head,
