NOVITATES ZOOLOGICAE XXIII. 19IÖ. 309 



Thauria 



Here I can only repeat what I have said in the Ann. Mag. Nat. Hist. (8) 17. 

 p. 475, 1916 — viz., that T. lathyi is a distinct species, and not a local form of aliris. 

 The Tring Museum possesses from the Tenasserim Valley, from Toungoo, Bnrmah, 

 and from Perak specimens of true Th. aliris pseudoliris with very narrow yellow 

 oblique hands on the forewiugs, which in the 3 have large androconial hair-tufts 

 in the cell of the hind wing, and other specimens with broader white bands to the 

 forewings and no androconial hair-tufts in the cell of the hindwing. Th. aliris 

 intermedia Crowley has very conspicuous androconial tufts. Below is the synoptical 

 table of the two species.

BRASSOLIDAE 



This family has been of late years revised by Stichel and Fruhstorfer, but I 

 have grave doubts as to whether it has been correctly treated. On the one hand 

 the typical genus Brassolis consists of heavily built small or medium-sized insects 

 with the general fascies of the moth family Castniidae, while their larvae resemble 

 large Hesperid larvae minus the thin long neck, being smooth and cylindrical, with 

 a largish and round horny head. On the other hand we have the genera Dynastor, 

 Opsiphanes, Dasyophthalma, Eryphanis, Caligo, and Narope, which either have 

 the general fascies of the Satyridae or of heavy-bodied Nymphalidae, while their 

 larvae have horned heads like Charaxes, and long rather fiat bodies with long 

 forked tails like Satyridae larvae. Then there is Penetes, of which the larva is 

 unknown, and appears in general fascies intermediate between Opsiphanes and 

 Brassolis, but nearer the former. 



I personally consider the genus Brassolis should alone be retained in the 

 family Brassolidae and the rest form a new family (Caligonidae) of their own, 

 which has been treated by Fruhstorfer as a subfamily only. Fruhstorfer, while 

 stating that the larvae of Dynastor were undescribed, nevertheless puts it calmly 

 into the section he calls subfamily Brassolinae without tail-forks. The truth is 

 that the larvae have long tail-forks, and I figure that of napoleon and that of 

 darius on PI. III. f. 5 and PI. VI. f. 13. 



CALIGONIDAE 



Dynastor napoleon Westw. 

 (PI. III. f. 5 larva, f. 6 pupa) 



Larva large and slug-like, bright grass-green with a number of short hairs ; 

 head rufous brown with two short spines on each side and a pair of much longer 

 ones behind. Along the back are four lozenge-shaped or longish oval chestnut 

 patches with a black central spot. The last segment ends in two very long tails.
