" Synchloe GLAUCONOME. 



Common both at Aden and Zaila. The larva feeds on Oleome 

 paradoxa in Aden, and inland on other plants. It is greenish 

 yellow, dotted all over with black. Three bluish streaks along the 

 whole length of body. No hairs. About 1| inches long when full- 

 grown. 



Pupa much the same colours and markings as the larva, but both 

 are fainter. 



" Heep-snia itbrata. 

 Given me by Lieut. Sparrow. 



" Nephbeonia aeabioa. 



I only got three or four specimens. 



" Papilio dbmoleus. 



Given me by Lieut. Sparrow. Col. Terbury got several 

 specimens of a Papilio (P. demoleus, I believe) at Lahej. 



" ISMENB ANCHISES. 



Two specimens at Aden and one near Zaila. 



" Chapea mathias. 



Common both at Aden and Zaila. 



" Gegenes kaesana. 

 Fairly common. 



" Pyegus adbnbn.sis. 



Fairly common. 



I think the differences in the larvte of such species of Teracohs 

 as I have described above are worthy of attention. The larva of 

 T. yerhurii is not in the least like any of the other larvfB I found ; 

 but this was the only red-tipped Teracolus larva I got, except one 

 of T. nouna, which so closely resembled T. yerhurii that I did not 

 observe any difference till the imago emerged. The larvae of 

 T.pleione and T. dynamene vary to some extent among themselves, 

 but in the case of T. dynamene I bred several varieties from one batch 

 of eggs : I got only two or three each of T. phisadia and 2'. acaste. 

 All these forms bear a kind of family likeness one to another ; and, 

 to some extent, this may be said of T. protomedia. I do not know 

 what Teracolus larvae have been described by others ; but, judging 

 from the larvae, T. yerhurii and presumably the other red-tipped 

 Teracoli should not belong to the same genus as the others." 



C. G. Nurse. 



I am afraid that genera based upon larval coloration would be 

 very unnatural ; moreover, the fact that Captain Nurse could not 

 distinguish between the larva of the scarlet- tipped T. yerhurii and 

 that of the orange-tipped T. evayore ( = nouna), seems to me to
