Larva green or redtlisli brown. AVe have four stages of the hirva of 

 iV. nccentifera from Mr. Leigh, Durban. 



First stage (one specimen) : green, a reddish shade from horn to thorax ; 

 ladin'' away in front ; horn black, jialer towards end. Head large ; thoracic 

 segment not smaller than following ; five bristles : two dorso-lateral, one above 

 stigma, two ventro-lateral ; horn about half the length of the bod}', curved 

 upwards, densely hairy, sinuate at tip, each angle with a stout bristle. 



Second stage (one specimen): head large, thoracic segments somewhat smaller 

 than the following ones : horn reduced in length, densely tuberculated, reddish, 

 tip pale, sinuate : npperside greenish, rest of body reddish ; head pale frontally, 

 with a pale lateral line ; a pale line from horn to eighth segment, widening 

 liehiud ; densely covered with ])ale dots. 



Third stage (one sjiecinien) : pale-dotted, reddish ; i)ro- and mesothorax 

 small, metathorax enlarged : a dark dorso-mesial line ; pale line from horn 

 frontad bordered by deeper red above and below, triangularly widening behind, 

 a pale oblique side-stripe over segments 4 and ij ; horn curving upwards, obtusely 

 pointed, granulose. 



Fourth stage (two sj)ecimens, one green, one brown) : strongly tapering from 

 fourth segment frontad ; pale-dotted ; markings as before ; horn stout, G mm. long, 

 depressed, somewhat tO-shaped, of even width, suddenly narrowed at end to a short 

 point (which is dorsal), tubercles numerous but small. 



The larvae of the Oriental species are very close to that here described.— 

 Food-plant : Carissa (in India). 



Pnpa long, pale brown : spiracles, an interrupted mesial line above and below, 

 cremaster and a series of ventro-lateral abdominal spots brown : glossy ; tongue- 

 case projecting forward, com]iressed, the frontal part (from eye onwards) about 

 twice as long as the head vertically high, no ventral carina ; labrum flat ; clypens 

 convex ; abdomen densely rugate-punctate above, more dispersedly punctured 

 beneath; praespiracular area of fourth and fifth somites rough with short carinae, 

 corresponding to the raised anterior edges of the nmbilicate punctures of the 

 following segments; cremaster short, broadly triangular, rugate, ending in two 

 strong points which curve U|)ward8. 



Ilab. Aethiojiiau and Oriental Region. 



Fifteen s]iecies, two Oriental, the others Aethiopian. 



Most of the species resemble each other closely in pattern. The antemedian 

 anil discal lines of the forewing are disposed as in most Macroglossum. Nearly all 

 the species occur in two forms, one with, one without white spot or spots on the 

 forewing. Owing to tlie variatiini in these spots, the absence, in some species, 

 of very striking distinguishing characters in jiattern, and the great similarity, 

 or i)ractically identity, in the sexual armature, the determination of the species 

 presents great difficulties. 



The forms witii the white sj^ots developed are the easiest to discriminate, and 

 we advise the reader who is trying to name some obscure species of JSepltcle to 

 liegin with sjiotted individuals, and then conjpare the not spotted ones with 

 thcra. 



The variously formed stigma of the forewing is deri\ed iVom four white dots ; 

 llic development of these in si mo sjitcies is illustrated on PI. LXV. Dot 1 is
