Stopping on the way at Charleston, S. C, Tybee Island, Georgia, and 

 Nassau, BaLama Islands, I used tbe limited time at each place to col- 

 lect. I arrived at San Juan, P. R., January 2, 1899, and worked from 

 there on tbe northern part of the island as far inland as Gaguas and 

 Bayamon. January 17 the Fish Hawk took me to Aguadilia, on tbe 

 northwest corner of the island, and leaving the steamer I worked on 

 foot and by rail south to Mayaguez and, after a few days, north and 

 west inland on horseback over Anasca, San Sebastian, Lares, Utuado, 

 and south to Adjunctas and Ponce, stopping at each place a few days. 

 From Ponce I again took the Fish Hawk, February 2, to Arroyo, in the 

 southeast corner of the island. After a few days' work from this point 

 inland as far as Guayama I remained on the steamer on its coaling trip 

 to Saint Thomas, Danish West Indies, and stopped on the way back sev- 

 eral days on the two American islands, Yiegues and Culebra. 1 lauded 

 February 13 on the east coast of Puerto Rico and worked over Humacao, 

 Fajardo, El Yunque, and Carolina back to San Juan and joined the 

 steamer there for the home trip, February 22, via Key West, reaching 

 Norfolk, Ya., March 8, and Washington, D. C, the next morning. 



Of insects injurious to the sugar cane in the held were especially 

 noted the common lepidopterous borer in the stalk, Diatrcea saccharalis; 

 Sphenophoms sexguttatus Drury, also boring in the stalks; a lamellicorn 

 larva common and destructive to the roots, and a mealy bug, Dactylo- 

 pius sacchari Ckll. The first of these was in some localities quite bad, 

 nearly every cane containing several specimens, but no intentional 

 remedy is undertaken. The annual cutting and crushing the cane 

 with all living larvae and pupa? naturally keeps the pest in check, but 

 the remaining roots and single canes always contain enough individ- 

 uals to infest the next year's growth. 



The coffee plantations seemed remarkably free from serious insect 

 pests. Of scale insects only Lecanium hemisphwricum was found, and 

 that very sparingly, and mostly killed by a parasitic fungus. The 

 coffee leaf-miner, Leucoptera (Cemiostoma) coffeella^wsiS very abundant, 

 the empty larval mines being often found three or four on nearly every 

 leaf, giving the trees a brown, withered aspect; but this did not seem 

 to injure the trees seriously, at least no attention was paid to the insects 

 by the growers. I was told several times about depredations of a 

 snout beetle, which at times does so much damage to " the leaves, 

 young shoots, flowers, and berries "as to kill the trees, and estate 

 holders pay a premium for each bushel collected and destroyed, but 

 during the dry season, when I was there, neither beetle nor damage 

 was visible. 



In the tobacco fields, among other insects met with, were the tobacco 

 Sphinx, Protoparce Carolina, both in larval and adult stage, and the 

 tobacco "split worm," Gelechia solanella, 1 which are also tobacco enemies 

 in the United States. 



Not hitherto recorded from the West Indies.
