546. *Terias eumide, Felder. 



Gi'ose Smith. Originally described from Celebes. Wallace gives 

 North Celebes and the Sula Islands as its habitat, with a " var." from 

 Batchian. We have seen nothing like it from Sumatra. 



547. *Terias latilimbata, Butler. 



T. latilimbata, Butler, Ann. and Mag. of Nafc. Hist., fifth series, vol. xvii, p. 221, 

 pi. v, fig. 5 (1886). 



Both sexes originally described from Sumatra. 



548. *Terias bidens, Butler. 



T. bidens, Butler, Ann. and Mag. of N'at. Hist., fifth series, vol. xvii, p. 222, 

 pi. v, fig. 7, female (1886). 



Originally described from Sumatra from a female. 



549. *Terias semifusca, Butler. 



T. semifusca, Butler, Ann. and Mag. of Nat. Hist., fifth series, vol. xvii, p. 222, 

 pi. v, fig. 8, female (1886). 



Originally described from Sumatra from a female. We are unable 

 to recognise any of these species of Mr. Butler's. 



All Terias are weak on the wiug, fly slowly, and never leave the 

 ground for a high flight. They are all, with the except"" n of T. harina, 

 Horsfield, found in open places, in gardens, on roads, and near houses, 

 the males frequently assembling in large numbers on wet spots on 

 roads and by the sides of rivers and streams. T. kecabe, Limueus, 

 sometimes appears in swarms, and its larva may then prove very des- 

 tructive to Cassia plantations. Cassia florida, Linnaaus, is its favourite 

 food-plant, on which the eggs are sometimes deposited singly as are the 

 eggs of the Catopsilias, but sometimes on a single leaf a large number 

 are placed in a rhomboid shape. In the latter case the green pilose 

 larva with a yellowish- white lateral streak and a black head (all the 

 larvae of Catopsilias have a head concolorous with the body) live in 

 societies, and the pupa are also suspended sociably, a fact not previously 

 we believe observed in Lepidoptera. If the pupa hang from leaves 

 they are green, if near the flowers of the Cassia they are yellow, and if 

 the caterpillars leave the food-plant and pupate on certain high 

 Graminess they are blackish-brown like the seed of the grass. As the 

 pupae are arranged at regular distances apart, the deception is a 

 very good one and must greatly protect them, as men, animals and 

 birds at a superficial glance would take these pupae to be only withered 

 flowers of the Cassia or ripe seeds of the grass. After six days in the
