‘¢ SYNCHLOE GLAUCONOME. 
Common both at Aden and Zaila. ‘he larva feeds on Cleome 
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. 
“ HERPENIA ITERATA, 
Given me by Lieut. Sparrow. 
‘‘ NEPHERONIA ARABICA. 
I only got three or four specimens. 
“¢ PAPILIO DEMOLEUS. 
Given me by Lieut. Sparrow. Col. Yerbury got several 
specimens of a Papilio (P. demoleus, I believe) at Lahej. 
‘« ISMENE ANCHISES. 
Two specimens at Aden and one near Zailu. 
‘* CHAPRA MATHIAS, 
Common both at Aden and Zaila. 
“ GEGENES KARSANA. 
Fairly common. 
‘** PYRGUS ADENENSIS. 
Fairly common. 
I think the differences in the larve of such species of Teracolus 
as I have described above are worthy of attention. The larva of 
TY. yerburii is not in the least like any of the other larve I found ; 
but this was the only red-tipped T'eracolus larva I got, except one 
of T. nowna, which so closely resembled 7’. yerburit that I did not 
observe any difference till the imago emerged. The larve of 
1’. pleione and T. dynamene vary to some extent among themselves, 
but in the case of 7’. dynamene I bred several varieties from one batch 
of eggs: I got only two or three each of 7’. phisadia and T’. acaste. 
All these forms bear a kind of family likeness one to another; and, 
to some extent, this may be said of 7. protomedia. I do not know 
what Yeracolus larve have been described by others; but, judging 
from the larve, 7’. yerburii and presumably the other red-tipped 
Teracoli should not belong to the same genus as the others.” 
C. G. Nurses. 
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 7’. yerburii and 
that of the orange-tipped 7. evagore (=nouna), seems to me to
