Some parasites of the cotton worm [in the West Indies] (Agr. News 

 [liarbadofi], 8 (1909), No. Hi), pp. 7.J, 7.5, figs. 2). — Vhalcis ovata and Sarco- 

 phaga tririttata were bred from the cotton worm. A species of Spirochalcis 

 was found to be parasitic upon C. ovata. 



Some insects injurious to truck crops. Miscellaneous notes on truck-crop 

 insects, ¥. H. Chittenden {U. >S'. Dcpt. Agr., Bur. Ent. Bui. 66, pt. 7, pp. 

 93-97). — Arsenate of lead at a strength of 1 lb. to 20 gal. of water applied dur- 

 ing the first week of June (in the vicinity of AVashington, D. C), followed by 

 a second application a weelc later at a strength of 1 lb. to 15 gal. of water, is 

 said to have controlled the asparagus beetle without injuring the plants. 



The asparagus miner (Agromijza simplex) is reported to have infested aspar- 

 agus at Antioch, Cal., and the asparagus beetle to have been abundant in that 

 locality. As the miner was also found at Oakley, Cal., the author concludes 

 that it is becoming generally distributed in the State. The asparagus miner is 

 reported to be well established in the vicinity of Portsmouth, Va., and the source 

 of severe injury at Concord, Mass. 



The pea moth {Enarmonia nigricana) , which has been known as a pest in 

 Canada for several years, has been discovered for the first time in this counti-y 

 at Chai'levoix. Mich. 



A new western root maggot (Pegomya jyld'iipalpis), which was received from 

 San Francisco, Cal., has been designated as the western radish maggot since 

 Idaho is the type locality. Two natural enemies bred have been determined as 

 Aphcvreta sp. and Polypesa sp. Water-cress leaf-beetles (Phwdon wruginosa), 

 received from Halltown, W. Va., were parasitized by a fungus which has been 

 tentatively determined as Entomophthora splicer osperma. 



Notes are also given on injury by the water-cress sowbug (Mancascllus hra- 

 vhgurus) at Shippensburg, Pa., and Lexington, Va. 



Western spread of the Colorado potato beetle, J. M. Aldrich (Jour. Econ. 

 Ent., 2 (1909), No. 3, p. 235). — The author reports the occurrence of the 

 potato beetle in the Bitter Root Valley and in Flathead County, Mont, and in 

 the town of Nez Perce, Idaho. The pest is said to have been established in the 

 latter neighborhood for at least 2 years and seems to have spread considerably 

 during the summer of 1908. It is pointed out that while the wet winters may 

 account for its inability to maintain itself in Idaho this cause does not hold 

 good in all the territory concerned. 



The banded pumpkin beetle (Aulacophora oliverei), W. W. Froggatt (Agr. 

 Gas. N. 8. Wales, 20 (1909), No. 3. pp. 209-212, pi. i).— This species is consid- 

 ered the worst leaf-eating beetle that gardeners have to deal with in New South 

 Wales, since it attacks all kinds of melons, cucumbers, pumpkins, and squashes. 

 In 1908 it was the source of considerable injury to the fruit of the cherry. 

 It is said that if the plants are dusted on the upper side with a plentiful sup- 

 ply of wood ashes, lime, or fine road dust the beetles will in most seasons leave 

 the plants alone. Paris green dusted over the foliage will drive the beetles 

 away. 



The greenhouse thrips, H. M. Russell (U. S. Dcpt. Agr., Bur. Ent. Bui. 6ft, 

 pt. 6, pp. .'i3-60, figs. 3). — The author has made a study in Florida of the life 

 history and means by which the greenhouse thrips (Heliothrips hwmorrhoi- 

 dalis) can be controlled. 



The thrips was found in 1907 to be the source of diseased conditions of 

 crotons in a greenhouse at Orlando, Fla. In 1908 it was reported to be the 

 source of injury to mangoes at Miami, Fla., to plants in greenhouses at San 

 Luis Obispo, Cal.. and to ornamentals in parks at Santa Barbara, Cal. The 

 injury, so far as known, is confined to the foliage, no reports having been made 

 of injury to blossoms. Since the species has been collected in widely distributed
