1896.] FROM ARABIA AND SOMAULANB. 247 



of specimens. Moat of them, I think, are T. yerbwii. I bred this 

 species from larvse found on plant No. 4 (this plant could not be 

 identified at B. M.) at Shaik Othraan. The following is a 

 description of the larva : — 



Head orange, lateral stripes of the same colour. Ground-colour 

 of back plumbeous, a darker stripe along centre, the whole faiutly 

 dotted with white. Below the lateral orange stripe there is_ a 

 slight protuberance on each segment, black in colour with white 

 dots. The whole larva is covered with short bristly hair. 



Pupa : — ground-colour pale lilac, with a purplish stripe along 

 centre and yellow lateral stripes. 



From all the pupce emerged typical T. yerbwii, except from one 

 which produced T. nouna, much to my surprise. I did not notice 

 that one of the larvse was different from the others, so the larva of 

 T. nouna must closely resemble that described above \ 



" Teracgltts daiea, $ (for ^ , see footnote). 



I have never come across this form on the Arabian side. 



" Teracolus antbtippb. 

 Given me by Lieut. Sparrow. 



" Catopsiha florblla. 



These I cannot properly separate. I bred some Gatopsilim from 

 larva) found feeding on plant No. 5 (Cassia sp. ? could not be 

 satisfactorily identified at B. M.). The following is a description of 

 the larva ; — 



Ground-colour pea-green ; a blaclt, intorrupled, but very distinct 

 lateral stripe, and below it a broader stripe of an orange-yellow 

 colour. The larva is rough, but not hairy ; the whole of the back 

 and head are covered with minute black dots. Length, when full- 

 grown, about 1| inches. 



The pupa is green. 



One came out typical florella 2 ; two others more like pyrene. 



" Belbnois mbsbntina, var. lordaoa. 



Swarms at Shaik Othman and in the desert generally. This, 

 both in the larval and imago stages, seems to be the same as 

 B. mesenihia. The larvaa feed on several plants, are gregarious, 

 hundreds being found on a single bush. They are greenish, slightly 

 hairy ; head black, dotted with white ; a broad chocolate-coloured 

 stripe on each side, faintly dotted with white. Some of them 

 remained only five days in the pupal stage. 



" BblBNOIS IBUCOGYNH. 



I did not find this species at all common, and only got two or 

 three specimens. 



^ Starved examples of thia species were separated and numbered from 252- 

 257 with the note : — " Tliia appears to be something different from T. yerburii." 

 The males of T. daira were confounded with T. yerbjirii. — A. G. B.
