like apex (wliich is less than half the diameter of the base), the surface 

 very smooth, with numerous miniite indentations, which, in occasional 

 imperfectly developed specimens,* are distinctly hexagonal. The other 

 three Indian genera — Brupadia, Biduanda and B^iasa — are less peculiar, 

 and Suasa is obviously related to Zeltus, Oheritra, and other normal 

 aphnoeiform genara. Their eggs lack the siibapical carina. In Driipa- 

 1^ dia and Biduanda, they are hemispherical, with rounded indentations 



larger than in Loxura. In Siiasa the indentations are large, shallow, and 

 distinctly hexagonal, looking as if impressed with a die. These six 

 genera form a series, approaching the Aphmmis group, but have soma 

 features iu common. They are all protected The forewing is short 

 and broad, the outer margin eroct, the costa strongly arched, the hind- 

 wing elongate posteriorly. The prehensors are elongate and of a pecu- 

 liar facies. 



An Arliopala, apparently inornafa, Felder, and one or two obscure 

 allied species undescribed from Malayana, have eggs somewhat as ia 

 Loxura, but coarser and without the cornice. This peculiarity is asso- 

 ciated with others in the imago, on which I shall foi-m the genus Ids, the 

 position of which is uncertain. 



The Thecla group has much smaller eggs nearly always greenish, 

 the lines enclosing triangular spaces, six of them radiating from each 

 tubercle, which is roughly spherical, constricted at the base. This 

 sculpturing, which is very distinctly cut, is elsewhere found only in tho 

 ooucavo eggs of certain Lycoininm. The section is a very indistinct one, 

 its members tending to unite severally with the Aphnmus or Arliopala 

 groups. I have had few opportunities of studying Zephyrus, and have 

 never examined the true Thecla. As a group they seem to have both 

 wings short and broad, the costa much rounded, the veins slender, the 

 hindwing usually with one tail. Surendra may be distinguished from 

 Zephyrus by tho obsolescent discocellnlar veins. So far as these are 

 visible, they are very upright, the middle one of the forowing unusually 

 long, dift'eriug widely in these respects from all tho succeeding genera, 



bo iiioorporatoii in liia key to the gonera of tlio T,>/cmiiida), lie has called it Eooxylides. 

 Jly dosoriptiou of the genua as well as those of ray genera Yasoda, Masssaga, 

 Armies and Taraha, all made in 188G, will appear in his next volnrae. I havereoord- 

 od Eooxyiidea tharis from Bassein, Barma, but it did not turn np in Tenasseriin. 



* Those curious eggs are usually rough or discolonred, and the sculpturing 

 differs more or less from that of tho others. I have found them in .all tho sections 

 of the Lyocenidm. They are usually exceedingly rare, but are more frequent in some 

 Arhopalas, so that their eggs may fairly be called dimorphic. They are not immature, 

 being qnito hard, and at least occasionally produce perfect larvas. I think they aro 

 atavisms, representing an earlier stage of development, tho egg perhaps of somo 

 remote ancestor.
