 A small cultivated kind of bamboo, commonly called Indian cane 

 {cana da India), frequently suffers from the attacks of the weevil, 

 Eretfiistes lateralis. Boh. The larva and imago feed on the soft 

 substance Hning the cavities of the bamboo joints, where the egg is 

 deposited by the female after piercing the stem by means of its rostrum. 

 The eggs are laid in several adjoining internodes, one in each, and the 

 female bores a circle of contiguous holes in the wall of the joint, rmder- 

 neath the lowest one which contains an egg. Sooner or later the stem 

 breaks at this place. The larvae hatch out after five days and consume 

 the iimer layer of the joint, and larvae bred in the Indian cane may 

 be transferred to the common bamboo, w^hich may also be used as 

 food for the imago. Though not precisely determined, the duration 

 of the larval period may be assumed to last some months at least. 

 A natural enemy of this Curcuhonid, Prodecatoma cruzi, sp. n. (Chal- 

 cidoidea), is described. The Hymenopteron deposits its egg on that 

 of Eresthistes as soon as the latter is laid. The imago emerges by boring 

 a cyhndrical hole through the wall of the bamboo stem, often using 

 the perforation made by the beetle. Eggs and larvae, probably of 

 E. lateralis, were found by the author at Alto da Boa Vista, Tijuca 

 Mountains (Rio), in another species of bamboo from which a few 

 specimens of P. cruzi were also bred. Indian cane is also attacked by 

 the Tenebrionid, Acropteron rufipes, Perty.

plusiae Coq. — Ann. Entom. Soc. America, Columbus, vii, no. 4, 



December 1914, pp. 301-306, 2 figs. 



Specimens of the Tachinid, Siphona plusiae, obtained by the author, 



were parasitic in the larvae of Phryganidia calif ornica. The adult 



female lays one or more eggs on the outer body wall of the host larva. 



After hatching, the larvae enter the body of the host, where they 



remain from 10 to 14 days. Hymenopterous hyperparasites were also 



bred ; these will seriously check the beneficial work of S. plusiaCy 



which has greatly aided in controlling P. calif ornica in CaUfornia.

 The following new species of phytophagous mites are described : — 

 Tenuipalpus bioculatus on privet and strawberry, causing defoliation, 

 especially in the autumn. Schwarr's insecticide gave satisfactory 

 results, and hme-sulphur was practically as good. T. yothersi was 

 found on camphor leaves in Florida and on oak, elm, and pecan in 

 South Carohna. In spite of the exposed position of this species on the 

 top of the fohage, very httle control seems to be exerted by rain. 

 T. banksi was collected from the under surface of castor beans and 

 velvet bean leaves. This important pest is controlled by a predaceous 

 mite {Sciidus sp.) and by the Coccinellid Stethorus sp. T. quinquenychus 

 was found on castor bean.
