of Cassia that occupies a corner of the road. Here they were 

 easily caught. 



4. Papilio Acamas. On three occasions only did a specimen 

 of this fine insect come into my hands, one of which was much 

 weather-beaten ; the others were in good condition. All were 

 taken at Sabito. It flies high, alighting occasionally on pro- 

 jecting twigs, twenty or thirty feet above the ground. 



5. Papilio Pelaus. This species is not uncommon, from April 

 to September, and is widely spread, being found in most loca- 

 lities that I have examined, except the wooded summit of Blue- 

 fields Peak. Its ordinary flight is low, irregular, and not very 

 rapid ; it dances along from bush to bush, and from flower to 

 flower, rifling them as it goes ; but, if pursued, its power of wing 

 is sufficient to carry it quickly out of reach. Yet, from its low 

 haunt and its fondness for flowers, it is not a difficult butterfly 

 to capture with the net. Pelaus, when sucking a flower, resting 

 on a leaf, vibrates strongly its half-erected wings in a peculiar 

 way, so as to be recognised almost as far as it can be seen. 



6. Papilio Polydamas. Rather common at certain times and 

 places. In May, on the road cut through the tall forest, between 

 Shrewsbury and Content, I observed it somewhat numerous, 

 flitting slowly over the low herbage, frequently alighting and 

 allowing itself to be approached, so as even to be captured with 

 the fingers. About the middle of June it was no less numerous 

 at Belmont, manifesting the same predilection for the rank herb- 

 age of the road-sides. The species occurred not unfrequently 

 also at Sabito, and along the road leading to Savanna le mer, 

 and was confined to no particular season. 



7. Pieris Monuste. Common in most situations, especially 

 during the earlier months of the year. 



8. Pieris, sp. nov. near Josephina (no. 114 of Doub. and Hewits. 

 Diurn. Lep.). This rather large species was sufficiently common 

 in the lowlands during the winter and spring. I met with it on 

 the heavy sand of Alligator Pond in December, and afterwards 

 somewhat numerously at Sabito and at the Hampstead Road. 



9. Pieris Margarita. I did not meet with this till the latter 

 part of March, when we obtained several specimens from Blue- 

 fields Mountain. It also occurred at Sabito and other lowland 

 localities. Sabito in March and April, and the Hampstead Road 

 in June are the great resorts of the Pierida : they commonly fly 

 low, coursing along the bushes and herbage by the sides of roads, 

 but frequently mount to the summits of the lower trees, and 

 play around them, when in profuse blossom, frequently alighting 

 in considerable numbers to suck. I have observed this habit 

 much more on the mountains than in the lowlands.
