Hindwings similar iu colour, but with a single vitreous spot onl}-, just bo}-ond 

 which is a transverse row of small round clots, and there is also a transverse line 

 one-third from the base of the wings. 



Undersiile, head, and hodij jjale brown. 



Exjjanse : 5 J inches = 136 mm.

TAGAROPSIS. 



Here there is nothing to say, except to record T. falcaUi Anriv. and T. denti- 

 fera co)ispersa Auriv. 



ORTHOGONIOPTILUM Karsch. 

 This genus contains three species : 0. odiegetiun Karsch, monochi-onmm Karseli, 

 and kunzei (Dew.). 



SYNTHERATA. 



Here S. wpymeri Maass., S. janetfu (White), S. mekilla (Westw.), and S. 

 disjtnicta (Walk.) are all the same species, as I have ever}- intermediate ; so the 

 genns works out as follows : — 



1. Syntherata janetta (White). 



ab. melinlla (Westw.). 

 ab. disjuncta (Walk.). 

 ab. tveymeri Maass.. 



2. S. godeffroyi Butl. 



3. S. loepoides (Butl.). 



Of Syntherata janetta ab. disjuncta I have had two specimens lent me b)' Dr. 

 Staudinger, of which the male is from Amboyna and the female from German New 

 Guinea, and I have jnst had three females and one male from Simbang, German 

 New Guinea. 



I have of S. loepoides (Butl.) two specmiens from Java, and I had one from 

 .Mt. Kina Bain, N. Borneo, lent me by Dr. Staudinger. 



ANTHERAEA. 

 I separate the African species included iu this genus by Mr. Kirliy luider the 

 generic name Nudaurelia. 



NUDAURELIA gen. nov. 

 Difters from Antkemea in having long cylindrical larvae with strong sjjines 

 arranged in rows and often branched, and naked pupae, the larvae going into the 

 ground instead of spinning a cocoon. The perfect insect differs principally in the 

 legs : in Antheraea the five joints of the feet are fully developed and flattened 

 laterally, the second, third, and fourth joints being together loiu/er than the first ; in 

 Nudaurelia, on the other hand, they are cylindrical and only fully developed iu the 

 male, the fourth joint in i\xe fetnale being minute and entirely atrophied, and in both 

 sexes the second, third, and fourth joints are together shorter than the first joint and 

 in some species barely half as long. The abdomen also iu Nudaurelia diflers from 

 Antheraea in that in the male it reaches the anal angle of the hindwings and in the 

 female beyond it, while iu Antheraea in the male it reaches half- way to the anal 

 angle and in the female two-thirds.
