Epitrix cucumeris Harr. 



Flea-beetles have been taken on eggplant and tomato/ which agree 

 with those taken in company with Epitrix parvula Melsh. on a weed 

 (PTiysalis sp.). Those taken on the latter plant were said by IMr. E. 

 A. Schwarz to be ''properly not different from the U. S. cucmnber 

 flea-beetle, Eintrix cucumeris J ^ On the eggplant the beetles were 

 causing the famihar ''flea-beetle injury" to the leaves. 



Ch^tocnema apricaria Suffr. 



This insect injures sweet potato leaves in much the same manner as 

 does CTiseiocnema confinis Lee. in the United States, searing them 

 with short, continuous, curved hues. The beetle is of a dark metal- 

 lic-green color and has been observed in abundance at certain seasons 

 on a common weed, related to the sweet potato. 



COPTOCYCLA SIGNIFERA Herbst. 



An adult of this "tortoise beetle" has been taken on the leaves of 

 sweet potato. In the United States the species is known as an enemy 

 of this crop. 



Cryptorhynchus batata Waterh. 



The writer is able to record this enemy of the sweet potato through 

 the kindness of Mr. R. H. Van Zwaluwenburg, Entomologist of the 

 Porto Rico Agricultural Experiment Station. Mr. Van Zwaluwenburg 

 has found it attacking sweet potato tubers at Mayaguez. The species 

 has been mentioned as an enemy of the sweet potato in the Lesser 

 Antilles, where it seems to be a more important pest than Cylasformi- 

 carius. 



Cyclas formicarius Oliv. 



The "sweet-potato root-borer" is present in Porto Rico, it having 

 been observed working in the tuberous root of a wild convolvulaceous 

 plant. 



LEPIDOPTERA. 



PlERIS MONUSTE L. 



The "southern cabbage worm" was mentioned by Mr. Tower in 

 his 1907 report (pp. 35 and 36) as feeding on cabbage, radish, turnip, 

 kale, and mustard. The male butterfly is shown in Plate II, figure 1. 



The larvse have also been found feeding on horseradish and an un- 

 cultivated plant, Cleome spinosa, of the family Capparidacese. This 

 weed is evidently an important wild food plant of P. monuste in Porto 

 Rico and is commonly found, especially on the lower lands, near the 

 rivers. Prof. Ignatius Urban gives it the local Spanish common 

 name of "jasmin del rio" in his Flora Portoricensis.
