 — Canadian Entomologist, London, Ont., xlviii, no. 4, April 1916, 

 pp. 113-116. 



The following new Chalcicls are described -.—Baoanusia africana, 

 parasitic on Saissetia {Lecanium) oleae in Cape Colony ; Catolaccus

Eriopus (Callopistria) fioridensis, Guen., which causes considerable 

 damage to ferns in greenhouses, can be controlled by spraying with 

 fresh p>Tethrum, 1 oz. to 1 gal. water,\\dth | oz. soap. The chrysanthemum 

 fly, Phytomyza {Napomyza) chrysanthemi, Kowarz, mines in the leaves of 

 greenhouse chrysanthemums and may cause a reduction in the number 

 and size of the flowers. Nicotine spray is a satisfactory remedy. The 

 Longicorn, Oberea tripunctata, Swed., is widely distributed in New Jersey, 

 but seldom in sufficient numbers to cause any serious damage. Its presence 

 can be detected by the withering of the leaves at the tip of infested shoots. 

 Hemichionaspis aspidistrae. Sign., on aspidistra and the lower leaves of 

 fern can only be removed by the destruction of infested parts. The 

 Chalcid, Isosoma orchidearum, Westw., is found in all orchid houses in 

 which Cattleya spp. are grown. Development and pupation takes 

 place within the bud, the latter finally becoming more or less swollen. 

 Fumigation with nicotine extracts to kill the adults is the most efficient 

 method of control. During June 1915, pine trees at Elizabeth were 

 found to be infested by a froghopper, Aphrophora parallela, Say, but no 

 injury to the trees could be detected. The larvae of Retinodiplosis {Ceci- 

 doynyia) resinicola, 0. S., were observed on the undersides of pitch-pine 

 branches in the same locality, but no apparent damage was caused. 

 Corythica arcuata. Say (lace bug) occurs on the leaves of oak and other 

 trees every summer in various parts of the State. In some seasons it is 

 sufficiently abundant to cause withering of the foliage. 



HoLLiKGER (A. H.). Aspidiotus ulmi, Johns. — Canadian Entomologist, 

 London, Ont., xlviii, no. 4, April 1916, pp. 143-144. 



Aspidiotus ulmi, Johns, is recorded on the following plants in 

 Missouri •.—Catalpa catalpa, Ulmus sp., Ptelea trifoliata and Juglans 

 nigra. The scales were abundant on all except P. trifoliata, where 

 they occurred only at the extremities of the twigs. P. trifoliata and 

 J. nigra have not been pre^dously recorded as host plants.
