564 EXPERIMENT STATION RECORD. (Vol.87 



Louisiana records of the bindweed prominent (Schizura ipomese), E. S. 

 TucKEB {Canad. Ent, 49 {1917), No. 8, pp. 280, 251 ) .—Observations of the oc- 

 currence and food habits of tdis lepidopteran in Louisiana are recorded. 



Nepticulidee of North America, Annette F. Braun {Trans. Amer. Ent. Soc, 

 45 {1911), No. 2, pp. 155-209, pis. 4). — In this synopsis of the family which in- 

 cludes the smallest species of Lepidoptera, the author recognizes 4 genera and 

 61 species (8 new), of which 54 belong to the genus Nepticula, 5 to Ectoedemla, 

 1 to Obrussa, and 1 to Glaucolepis n. g. With the exception of several gall- 

 making species of Ectoedemia, the larvae of all species of which the life his- 

 tories are known are miners within the tissues of leaves or in bark, but rarely 

 in fruit. They show a preference for trees and shrubs, but not a few mine 

 leaves of herbaceous plants, when full grown, the larva, with a few exceptions, 

 leaves of herbaceous plants. When full grown, the larva, with a few exceptions, 

 amongst the rubbish or in the loose surface soil. The species of Ectoedemia 

 are gall producers or bark miners in forest trees. A list of their food plants 

 and descriptions of mines occurring on them, compiled as an aid in identifica- 

 tion, is included. 



The pink bollworm, Pectinophora gossypiella, A. Busck (J7. S. Dept. Agr., 

 Jour. Agr. Research, 9 {1917), No. 10, pp. S4S-S70, pis. 6, figs. 7).— This is a 

 summary of the present status of knowledge of the pink bollworra, (Gelechia) 

 Pectinophora gossypieUa. This is based upon a review of the literature and in- 

 vestigations conducted by the author, the biological part of which was made in the 

 Hawaiian Islands, where the cultivation of cotton has been abandoned on ac- 

 count of its injury. 



The new genus Pectinophora Is erected by the author for this species. It is 

 pointed out that even a fraction of the insect in any of its stages can be recog- 

 nized under the microscope by the characters given in this paper. 



The paper includes (pp. 3C2-3G6) a similar detailed descriptive and anatomi- 

 cal account of another lepidopterous insect {Pyroderccs rilcyi), known as the 

 " scavenger bollworm," since it frequently occurs in decayed or dried bolls In- 

 jured by other insects. This frequently has been and may be mistaken for the 

 pink bollworm, but the anatomical details given in this paper make it possible 

 for the inspector to distinguish readily these two insects. 



A bibliography of 48 titles is Included.
