Title: On the occurrence of two subspecies of Hypsopygia costalis in Malta (Lepidoptera, Pyralidae) Authors: Catania, Aldo; Seguna, Anthony; Sammut, Paul Abstract: Hypsopygia costalis (Fabricius, 1775), has been recorded for the Maltese islands from two specimens collected by one of us (AS) on May 16 and June 7, 1998 from Naxxar (SAMMUT, 2000) and seems to represent a rare species. These two specimens proved to belong to the nominal subspecies.

Title: The Nepticulidae of Malta (Lepidoptera) Authors: Zerafa, Michael; Nieukerken, Erik J. van Abstract: Three species of Nepticulidae are recorded for the fi rst time from the Maltese Islands. Acalyptris minimella, Ectoedemia euphorbiella, and Parafomoria pseudocistivora are added to the previously recorded Stigmella aurella. A short description of the adults and notes on ecology are given. Information on the egg oviposition and number of mines on leaves collected locally is provided for all species. Adults and mines are illustrated and distributional data is also provided.

Title: The Scarabaeoidea of the Maltese Islands (Central Mediterranean) (Coleoptera) Authors: Pivotti, Igor; Agoglitta, Rossana; Zunino, Mario; Piattella, Emanuele; Dellacasa, Marco; Corallini, Carla; Mifsud, David Abstract: The Scarabaeoidea of the families Trogidae, Geotrupidae, Hybosoridae and Scarabaeidae from the Maltese islands are reviewed. A total of 54 species are included of which the following eight species represent new records for this archipelago: Trox fabricii and T. scaber in Trogidae; Aphodius beduinus, A. algiricus, Amphimallon (?) scutellare, Aplidia hirticollis, Protaetia opaca and Lasiotrichius succinctus in Scarabaeidae. Of these, the record of Aplidia hirticollis, previously endemic to southern Italy, extends its distributional range further south and that of Lasiotrichius succinctus is based on intercepted material and its local establishment is not confi rmed. A number of species are based on old records and were not collected again recently pointing out to the possible extinction of these species from Malta. The almost complete absence of grazing animals in Malta may have contributed substantially for the disappearance of species associated with animal dung. Thirteen previously recorded species of Scarabaeoidea from Malta are being excluded from the Maltese fauna.

Title: Aphids associated with shrubs, herbaceous plants and crops in the Maltese Archipelago (Hemiptera, Aphidoidea) Authors: Mifsud, David; Mangion, Marija; Azzopardi, Erika; Espadaler, Xavier; Cuesta Segura, David; Watson, Gillian W.; Perez Hidalgo, Nicolas Abstract: A survey of the aphids associated with Maltese shrubs, herbaceous plants and crops was carried out. Sixty six aphid species were recorded from more than 90 species of host plants. Forty eight aphids were recorded from the Maltese islands for the fi rst time bringing the total number of aphid species known from these islands to 99. New records include: Acyrthosiphon lactucae, A. pisum, Anoecia vagans, Aphis alienus, A. euphorbiae, A. hederae, A. lambersi, A. multifl orae, A. nasturtii, A. parietariae, A. picridicola, A. ruborum, A. sedi, Aulacorthum solani, Brachycaudus helichrysi, Capitophorus sp. nr. similis, Clypeoaphis suaedae, Cryptomyzus korschelti, Dysaphis apiifolia, D. foeniculus, D. pyri, D. tulipae, Hyadaphis coriandri, H. foeniculi, H. passerinii, Hyperomyzus lactucae, Idiopterus nephrelepidis, Macrosiphoniella absinthii, M. artemisiae, M. sanborni, Macrosiphum euphorbiae, Ma. rosae, Melanaphis donacis, Metopolophium dirhodum, Pterochloroides persicae, Rectinasus buxtoni, Rhopalosiphum maidis, R. padi, R. rufi abdominale, Schizaphis graminum, Semiaphis dauci, Sipha maydis, Sitobion avenae, S. fragariae, Therioaphis alatina, Uroleucon inulae, U. hypochoeridis and U. sonchi. Of these 99 aphid species, 58 are of economic importance and 16 are alien introductions. For 15 of the aphid species, a total of 22 new host-plant records are made. Ten species of ants were found attending 18 aphid species.
