An article concerning the appearance and injuries of the screw 
worm in Mississippi has lately been published by Mr. H. E. Weed, of 
the Experiment Station of that State, in the Southern Live Stock

North American Phycitidee.— After many years of study of 
the small moths of the family Phycitide, Rev. Geo. D. Hulst has pre- 
pared a monograph of unusual excellence. It has been published 
under the title, ** The Phycitida of North America," in the Trans- 
actions of the American Entomological Society (Vol. XVII., pp. 93- 
228, Plates vi.-vin.) ‘The systematic list given at the end of the article 
includes 201 species, although the author states in the opening para- 
graph that **it is probable that not half of our species have as yet been 
described." This monograph cannot fail to be of great value to 
working entomologists, and ought greatly tó stimulate the study of 
these beautiful little moths. The early stages of only twenty-six species 
are recorded as known. The author, following his previous custom, 
has proposed a number of new generic terms derived from the names 
of extinct Indian tribes. The generic references of nearly all the well- 
dnown economic species have been changed; e.g., the leaf crumpler 
(Phycis indigenella of authors) is now Mineola indigenella; the leaf 
skeletonizer, which so long has been called Pempelia hammondi, now 
goes to the genus Canarsia ; Professor Comstock’s Dakruma coccidivora 
has become a Lætilia, and the time-honored Zphesta interpunctella 
has gone back to Guené’s genus Plodia, in which it seems to have been 
originally placed by Hiibner. But these changes are inevitable, and 
we can only trust that the insects mentioned have received a fairly per- 
manent generic assignment. 
New Food-Plant of Rhodobznus 13-punctatus.—Pupez and 
adults of this species were found in the stems of cupweed (Si/phium 
perfoliatum) July 30, 1890, in central Ohio. The beetles were freshly 
emerged, and were crawling up the inside of the stem, evidently pre- 
paring to escape. The pupz were in the basal portion, where abun- 
dant evidence was visible of the work of the larve. The latter had 
bored the root and basal part of the stem. No larve could be found 
at this time, all having pupated. The two later stages of the insect 
are shown at Fig. 1, a representing the pupa, and 2 the beetle. The 
larva has been described by Dr. Riley in the Report of the U. S. De- 
partment of Agriculture for 1881-1882 (p. 142); and in his third
