Madagascar. I believe its advent to be quite recent, as 
I can scarcely credit such an excellent observer as the late 
Dr. Vinson overlooking it. 
Cupido (Tarucus) telicanus, Lang. 
20. Lycena Telicanus, Herbst. 
Very abundant in both islands. Flies, I-V, abundant ; 
VI-VIII, none; IX—XII, abundant. All my specimens 
appear to me to be remarkably dark. 
Cupido (Lampides) beticus, L. 
19. Lycena Betica, Linn. 
More common in some years than in others, sometimes 
abundant. The larva fecds in the interior of pea-pods, 
and not unfrequently gets cooked and brought to table, 
on which occasions it may be regarded as a nuisance. I 
have known it to be so abundant as to cause a serious 
diminution in the pea crop, and in some seasons to be 
quite scarce. In Bourbon it is likewise of irregular 
occurrence. Fhes all the year round. The larva and 
pupa have been described frequently. 
Cupido (Zizera) gaika, Trimen. 
Not recorded hitherto from Mauritius, but widely dis- 
tributed and usually very common, fluttering about short 
herbage or settled on the flowers of Lantana. It varies 
greatly in size, and the female, as is so frequently the 
case in this genus, varies very much in the amount of 
blue on the upperside. Fles, I-IV, common; VI, scarce ; 
VII, VIII, scarce or absent; I[X=XII, very common at all 
elevations. 
Bourbon. Not previously recorded, but I found it very 
common on the racecourse at St. Denys, and it doubt- 
less occurs elsewhere. The transformations have been 
described. 
Cupido (Zizera) lysimon, Hiibner. 
21. Lycena Lysimon, Godt. 
Very abundant both in Mauritius and Bourbon. The 
specimens are usually very fine, and larger than the 
general run of Indian specimens. It is found in more
