142 LEPIDOPTERA INBICA. 



in some more or less sligHtly scalloped. Sindioings short, generally broad and 

 triangularly-ovate, in some obovate ; exterior margin more or less slightly scalloped. 



Catbepillae. — Head cleft, or serrate, on vertex ; body either unequally humped 

 dorsally, or more or less cylindrical ; armed with two subdorsal more or less 

 incomplete series of mostly short, irregular-shaped fleshy branched-spines. 



Cheysalis. — Somewhat elongate, or short ; with projecting wing-cases, broad 

 rounded elevated anterio-dorsal prominence, arched thorax, and projected bifid head- 

 piece. 



Egg. — " Very large; few ; soft; not so high as wide, strongly reticulate, with 

 elevated translucent lines crossing the surface asymmetrically, enclosing pentagonal 

 spaces, and bearing long, acute, often bifid spines at their intersection." (Doherty.) 



Seasonal Dimoephism. — This is known to occur in the species of our Limenitid 

 genera Auzahia and Lebadea, also in the Athymid genera Tacorsea, Condochates, 

 Pantoporia, and Kironga, and in the Neptid genera Andrapana, Neptis, Bimhisara, 

 Stabrobates, Bahinda, and Lasipj^a. In the typical species of the two latter genera, 

 in addition to the ordinary seasonal differences, the male of the dry-season form has 

 the usual unglossed patch of scales on the upperside of the hindwing restricted to the 

 basal interspaces of the subcostals, being thus conspicuously isolated within the 

 middle area of the broad glossy costal border, whereas, in the male of the wet-season 

 form this unglossed patch pervades the interspace below the subcostal. 



Chaeacteristics of Males in ceetain genera. — Tn the various species of our 

 Athymid genera we have found Androconia, or scent-scales in a very limited number, 

 only, to be present in the males of Tatisia Kaniua, Tharusia Jina, Ghendrana Pravira, 

 Athijma Perius, Gondochates opalina, in all the species of Pantoporia (Nefte, Cama, 

 etc.), Sabania speciosa, Kironga Banga and K. Abiasa; Dr. Haase (Iris, 1883, 305) 

 records them as being present also in Balanga, Kasa. These scent-scales are found 

 interspersed between the ordinary scales chiefly upon the basal area between the 

 median and submediau vein on the upperside of the forewing ; they are extremely 

 minute, elongated, broadest and rounded anteriorly and finely ciliated in front, the 

 base on each side angled hindward into a fine projecting pointed-hook longer than the 

 basal shaft. These peculiar scent-scales were, however, not found to be present in 

 the allied Athymids Parathyma Sulpitia, Tacorasa Asara, and Tacola Laryinna, 

 neither were they found in the species of our Limenitid genera, which were carefully 

 examined for this purpose. 



In the males of our various genera of ISTeptids, the underside of the forewing has 

 a more or less broad glossy posterior border, which in some, i.e. Pheedyma, Bahinda, 

 Lasippa, etc., encompasses an elongated patch of dark-coloured (? scent) scales ; and 

 on the upperside of the hindioing an ordinary more or less broad brilliantly- 

 glossed costal border, and in Phsedyma (Heliodora, Oram.), also a conspicuous less-
