wing. The river banks at the landing-places for boats always 

 seem to be the best for PapUios.'' 



Among the specimens Dr. Davis sent me were two, male 

 and female, of Terias nicippe, a well-known Mexican insect. 

 Only four specimens in all were seen, and they were flying 

 on the open savannah. Although T. nicippe ranges as far 

 south as Guatemala, this is apparently the first record for 

 British Honduras. Dr. Davis has not previously met with 

 it in the colony, nor have I received it in the consignments 

 sent home by my collector. T. euterpe, Menet. {lisa, Boisd.), 

 was taken in considerable numbers, and Dr. Davis observed 

 the female depositing eggs on a "sensitive plant." 



I have put in the drawer specimens of all the Papilios and 

 Pierids I received from Dr. Davis, taken on this journey, and 

 also some insects belonging to other Families. 



Early stages op Caligo memnon. — In the drawer is a 

 specimen of Caligo memnon, an insect which appears to be 

 rather common in British Honduras. My collector writes 

 me that he watched a female ovipositing. The eggs were 

 laid on canna, and he secured eight of them, which he took 

 home, and in about eight days the young larvae emerged. 

 They took about two months to reach maturity, and when 

 fully grown were pale yellow-green, with a brown spot in the 

 centre of the back. Their length before pupating was ap- 

 proximately five inches and they were about as thick as an 

 ordinary lead pencil, tapering at each end. They had two 

 processes, which he calls " horns," at the back of the head, 

 about one-fourth of an inch long, with two smaller ones 

 behind them. ^Vhen touched or otherwise irritated the larvae 

 would throw their heads from side to side as though threaten- 

 ing an attack with their " horns." He describes the posterior 

 end of the larva as having two " horns " which pointed back- 

 wards, each point inclined a little to one side. The young 

 larvae made cuts in the edge of the leaf and rolled the 

 piece thus freed into a case in which they remained con- 

 cealed during tlie daytime. When they got bigger tliey hid 

 either in these cases or in tlie hollows of the stems. He has 

 found the caterpillars on canna, wild canna and banana. 

 When fully fed the larva attaches itself by the anal extremity
