Bol.) a species widely^distributed in India. A description of this 

 parasite, ;which probably belongs to the genus Lepidoscelio, Kieffer, 

 is given under the name L. viatrix, sp. n. 



The adult females firmly attach themselves to the abdomen of the 

 locust, their mandibles being imbedded in the body between the 

 abdominal plates. By this means, parasitisation of the eggs can take 

 place immediately after oviposition by the host.

The insect enemies of the cow pea ( Vigna unguiculata) are few, the 

 worst being the cow-pea bruchus, which attacks it in storage, but 

 which can be destroyed by fumigation with carbon bisulphide, and 

 Heliothis obsoleta (armigera) (cotton-ear worm), damage by which can 

 be avoided by rotation of crops, clean and rapid cultivation and 

 proper fertiUsation.

 Entom. News, Philadelphia, xxix, no. 3, March 1918, p. 114. 



The Microlepidopteron, Gracilaria zachrysa, Meyr. {azaleae, Busck) 

 was originally introduced into Holland from Japan and infests all 

 Japanese varieties of azaleas, as well as Azalea indica, greenhouse 

 azaleas being injured during the winter. In New Jersey it is knowTi 

 to occur in many private greenhouses and is considered a pest of 

 some importance, commercial houses in consequence holding over as 

 little azalea stock as possible from year to year. 



The larvae mine the leaves and also fold over the tips, and in some 

 cases they have been suspected of eating through the buds. They may 

 be controlled by means of nicotine extract used either as a spray 

 or a fumigant, by handpicking the infested leaves, or by the use of a 

 stomach poison, lead arsenate paste (at the rate of 8 lb. to 100 U.S. 

 gals, water) having yielded good results. 



Glaser (R. W.) & Wilcox (A. M.). On the Occurrence of a Mermis 

 Epidemic amongst Grasshoppers. — Psyche, Boston, Mass, xxv, no. 1, 

 February 1918, pp. 12-15. 



Two species of grasshoppers, Melanoplus atlantis and M. hivittatus, 

 are extremely bad pests of maize, wheat, oats and clover in the State 

 of Vermont,' but in the latter part of August and the beginning of 

 September 1917, the rate of mortality among them was found to be 

 unusually high. This proved to be due to the presence of a parasitic 

 Nematode, Mermis sp. probably M. ferrugijiea, which is said to be a 

 common parasite of Locusta Carolina near Philadelphia. This worm, 

 the females of which measure from 2 to 8 inches, was located in the 

 body cavity, generally singly, though in one case as many as 40 were 

 found in one grasshopper. Late in the season, the worms are known 

 to emerge by boring through the body wall, and reaching the earth, 

 slowly bore into the soil and coil up at a depth of 6-12 inches 

 beneath the surface, undoubtedly hibernating in this position.
