Other NocTuiDiE. 



Three other noctuid moths, that have been reared from larvae, 

 belong to the species known to injure truck crops in the United States. 

 Xylomyges eridania Cram., the larvae of which occurred on AmarantJius 

 sp., has beeji mentioned by Messrs. Chittenden and Russell under the 

 name of Prodenia eridania Cram.^ as attacking Irish potatoes, egg- 

 plant, pepper, okra, and sweet potato in Florida, and they give, on 

 another's authority, beets, cabbage, and carrots as food plants. 



Prodenia ornithogaUi Guen., the cotton cutworm, reared from larvae 

 found feeding on a weed of the family Convolvulaceae, is stated by 

 Dr. Chittenden to be an enemy of several vegetable crops.^ 



The larvae of Feltia annexa Treits., which species has been reared 

 from larvae found in an area where "grass worms" (LapJiygma frugi- 

 perda S. & A. and Remigia repanda Fab.) were abundant, is known 

 as a cutworm on the mainland. 



DiAPHANIA HYALINATA L. 



Cucumbers and squashes are frequently severely attacked by the 

 larvae of this species, the melon caterpillar. Mr. Barrett mentioned 

 the species in his 1903 report (p. 448). 



Pachyzancla bipunctalis Fab. 



The "southern beet webworm" has been found feeding on garden 

 beans, sword bean {Canavalia ensiformis), and weeds belonging to 

 the genus Amaranthus. Upon the garden bean and Amaranthus it 

 was feeding on the leaves, which it webs together, forming for itself 

 a shelter, as is commonly done by pyraHd larvae. The leaf or leaves 

 of which the shelter is formed are skeletonized and the pupae are 

 sometimes found in the shelters, but more often in earthen cells just 

 below the soil surface. The larvae found on sword bean were feeding 

 within the green pods. 



Exorista pyste Walk., a tachinid parasite of the larvae, has been 

 observed. 



In connection with Pachyzancla hipunctalis it may be mentioned 

 that another pyrahd, Eymenia (Zinclcenia) fascialis Cramer, occurs 

 in Porto Rico. It has been observed under conditions that would 

 indicate that the larvae feed upon Amaranthus spp. Mr. H. O. Marsh 

 has studied this species in the Hawaiian Islands, and in Bulletin 109, 

 Part I, of the Bureau of Entomology, states that various beets and 

 several species of Amaranthus are among the plants which suffer 

 from its attack there.
