liave been more extensively made, particularly in the Province of 

 Buenos Aires and in Uruguay. In localities where the [)arasites are 

 established, it is still advisable to destroy bagwornis during the winter. 

 T. platensis and P. caridei are rarely found within the bags at this 

 time, while the females of 0. platensis, being incapable of flight and 

 living entirely within the bags, may be destroyed with advantage. 

 Investigations will be made as to the establishment of the parasites 

 in the various localities to which thev are sent.

A number of insects are enumerated that were sent for identification 

 from Rio Grande do Sul (Brazil) and La Plata (Argentina). Among 

 these are the Diptera : Lasiopa atrata, F.. which has been reared on 

 })eaches and is therefore presumably an injurious species ; a Syrphid, 

 Baccha clavafa, F., the larvae of which feed on Aphids ; Sarcophaga 

 blandita, sp. n., which is parasitic on a Mantid ; S. lubera, sp. n., 

 and S. clotho, sp. n., which are parasitic on the locust Schistocerca sp. 

 in Rio Grande do Sul; Anastrepha fraterculus, Wied., which has been 

 reared on Araca [Psidium araca] ; Euxesta eluta, Lw., the larva of 

 which destroys the pulp of oranges ; Agromyza gnaranitica, sp. n., 

 the larvae of whicli mine the leaves of cultivated Chrysanthemum ; 

 Agro)u>/za niareUii, sp. n., on which further data will be published. 



Lepidoptera : Melittia riograndensis, sp. n., breeding on the shoots 

 of pumpkins ; Neopyralis ronnai, gen. et sp. n., breeding on prickly 

 pear ; Aiumalo helops. Cram., injurious to fig-trees ; and Tinea peUion- 

 ella, L., the common clothes moth. 



Hymenoptera include Catuponotus mvs, Rog., a scavenger ant ; 

 Ipobracon oeceticola, sp. n., which is parasitic on the bagworm, 

 Oeceticus platensis ; Apanteles riograndensis, sp. n., which is parasitic 

 on Tinea pellionella ; A. ayerza, sp. n., a parasite of Colias leshia ; 

 Cecidopimpla ronnai, gen. et sp. n., parasitic on the Lepidopteron, 

 Cecidoses eremita ; Trichomalus hesperocharidis, sp. n., parasitic on 

 larvae and pupae of a Le])idopteron, Hesperocharis sp. ; Prionomitus 

 byasiliensis, sp. n., found parasitic on the larva of a moth injurious 

 to albahaca [Ocymum basilicum] ; Habrocytus platensis, sp. n. ; 

 Perissopterus caridei, Brethes, and Tetrastichus zemani, sp. n., parasitis- 

 ing Ceroplastes rusci, L.. on orange-trees in La Plata ; Tetrastichus 

 oeceticola, sp. n., a parasite of Oeceticus platensis ; and CirrospHus 

 mellevs. sp. n.. a ])arasite of a Lepidopterous larva.

An appeal is made for co-operation in the destruction of sparrows, 

 which have estabUshed themselves in Argentina at the expense of 

 the native beneficial birds, many of which are of considerable value 

 in destroving insects.
