Ormenis pruinosa Say. — Nymphs nearly full grown and a few adults 

 of this species were found during the last week of June, 1899, upon 

 apple at Cabin John, Md. Some were upon the leaves and some upon 

 the stems of the fruit. They readily attract attention by the soft white 

 flocculent substance which is secreted and forms in a light mass about 

 the nymphs and which remains for some time after the nymphs have 

 issued as perfect insects and gone to some other portion of the plant. 

 Nymphs and adults were also found in great abundance on plum, both 

 at this place and in the 'District of Columbia, as well as on cherry, 

 potato, three-sided Mercury (Acalypha virginica), virgin's bower 

 ( Clematis virglniana), and trumpet creeper ( Tecoma radicans). Although 

 a general feeder this species appears to favor climbing plants. 



This hopper has received rather frequent mention in different eco- 

 nomic, including governmental, publications. The first of these that I 

 find is by Miss M. E. Murtfeldt (Bui. No. 13, o. s., pp. 61, 62), in which 

 special reference is made to destructiveness to foliage and stalks of 

 dahlia at Kirkwood, Mo., in 1886. In one garden plants were injured 

 beyond recovery. In volume IV of Insect Life (p. 142) brief notice is 

 given of reported ravages on so-called "California hedge plant 7 ' in 

 Texas. In volume Y of the same publication (p. 155) it is mentioned 

 briefly by Miss Murtfeldt among the enemies of Osage orange, and in 

 Bulletin No. 32 (p. 38) the same writer states that the insect was 

 remarkably abundant in 1893 in vineyards in Missouri, where it was 

 popularly mistaken for u mealy bug," and that it caused considerable 

 blighting of the leaves and twigs. A still longer account was given in 

 the Fifth Eeport of the United States Eutomological Commission (p. 

 281) from notes by Professor Eiley, the food plants mentioned includ- 

 ing elm, hackberry, maple, red clover, and Erigeron canadense. Illus- 

 trations of the species and a short account of its habits and of the 

 method of its attack on sassafras were given by the same writer in his 

 Fifth Missouri Eeport (p. 122). 



Chlorochroa conica Say. — This beautiful green species was taken in 

 some numbers at Colonial Beach in July, 1897. The adults fed upon 

 grape, and it was reared from nymphs found on the same plant. Its 

 favorite food plant was not grape, but hop, and its occurrence on grape 

 was due to an overflow from the hop vines upon which it was present 

 in large numbers. 



This species has also been recorded as occurring on Osage orange 

 and lilac, the tender shoots of which plant, according to Miss Murtfeldt 

 (Bui. No. 13, 1. a), it weakens in the same manner as does the Ormenis. —

COTTON INSECTS IN EGYPT. 



In the May and June numbers of the "Journal of the Khedival 

 Agricultural Society," published at Cairo, Egypt, there is an article by 

 Mr. George P. Foaden on "Insect and other pests injurious to cotton in 

 Egypt." The author deals chiefly with two insects, the cotton worm, 

 Prodenia littoraUs, and the boll worm, Earias insulana.
