B. pmininus, Horn, has been bred experimentally from the following 

 additional food-plants : Cassia siamea, Sarnanea saman (monkey pod) 

 not previously known to be attacked by Bruchids, Acacia decurrens, 

 Seshania coccinea and Cassia grandis. 



B. quadrimaculatus, so far only known as a serious pest of pigeon 

 peas and cowpeas in storage, is now reported on the latter in the field. 

 It is parasitised, as is also Calandra oryzae, by Chaetospila elegans, 

 Westw., but this parasite is practically of no use in controlling these 

 pests. 



Pachymerus gonagra was successful in completing its growth in a 

 pod of Cassia nodosa in February 1918, by proceeding from one 

 withered seed to another. Its apparent low parasitisation in certain 

 districts by Uscana semifwnipennis, Gir., is probably accounted for 

 by the presence of only two food-plants. Acacia farnesiana and Prosopis 

 jidifora, of which the seeds only ripen in particular seasons so that 

 the insects do not breed continuously through the year thus limiting 

 the opportunity of the parasites for multiplication. The two-spotted 

 bean weevil has been identified as Spermophagus pectoralis, Sharp.

The species dealt with include Perisierola emigrata, Rohw., 'hitherto 

 only known as a predator upon the pink bollworm {Pectinophora 

 gossypiella). It was found in May attacking the larvae of CryptopMehia 

 illepida and Myelois ceratoniae feeding on Acacia farnesiana. In 

 confinement it will also attack Pyroderces rileyi, Ephestia elutella, 

 Crocidosema lantanae, Tortrix (Archips) postvittana, and other moths, 

 as well as the grubs of the Anthribid, Araecerus fasciculafus, and the 

 Bruchid, Pachymerus gonagra. When the host has succumbed to 

 attack, P. emigrata feeds on its juices at the point of the sting and 

 commences oviposition on its surface about one or two hours later. 

 The number of eggs deposited varies according to the size of the 

 larval host. 



The endemic Hawaiian species of Sclerodermus are also discussed. 

 Among these S. immigrans, Bridwell, and S. manoa, sp. n., were 

 found experimentally to attack Bruchid larvae.

Paranagrus osborni, sp. n., is described from the Philippine Islands 

 where it was bred from eggs of Peregrinus niaidis.

Epyris extraneus may be found in Hawaii at all seasons of the year. 

 It preys under natural conditions on the larva of Gonocephalum seriaimii, 

 which may be found under cane trash and other rubbish, on which
