SALVATORE VICIDOMINI

Abstract - Xylocopa (Xylocopa) violacea (Linnaeus, 1758) (Hymenoptera: Apidae): preliminary study on the sexual dimorphism. II - A quantitative study on the head sexual dimorphism (F-M%) in a Campanian (South Italy) pupae population of Xylocopa violacea (L.) (Apidae: Xylocopini). Sexual dimorphism is significant for all characters (F-M% ≥ 1). For two characters, male mean is higher than the female one [F-M% < 0; Fr, Fx(XI)], mainly for the male additional flagellomere. Little significant (1 ≤ F-M% < 5) is the sexual dimorphism for OCmin. LgSC1/2, FI and Fx(XI) characters; highly significant (F-M% > 30) for OVP-MPC, OVP-OC, LgMb and LgM1/2 characters; normally significant (5 ≤ F-M% ≤ 30) for the other 19 characters. Antennae characters show a non significant sexual dimorphism (F-M% = 0.42) for their important function in both sexes. Compound eyes (12.71) and toruli (13.95) characters are only affected by the different sizes of the two sexes, because show the same dimorphism of pupal total length. Visual ocelli (32.61) and mandibles (31.18) characters show a significantly higher sexual dimorphism with respect to pupal total length, mainly because the nest is bored by the female only.

ENRICO BARBERO & MARCO RASTELLI

Abstract - Notes on the Silphidae (Coleoptera) of the Gerbasso Wood, Carmagnola (TO), Italy - The Gerbasso Wood is a renaturalized area in the territory of the Municipality of Carmagnola (Turin province) in the Po river Park (Piedmont, NW Italy). During the years 1999 and 2000 a study on the carrion beetle population (Coleoptera, Silphidae) was carried out in this area. 733 individuals belonging to 7 species were collected. In this paper an annotated list of the species is reported and some aspects of the structure of the carrion beetle population are discussed.

Observations on the habitat and apparently

new larval host plant of Phalaenoides glycinae (Lewin, 1805)

(Lepidoptera: Noctuidae: Agaristinae)

in the Sydney district, New South Wales, Australia

by

TREVOR J. HAWKESWOOD & JAMES R. TURNER

Abstract - Notes are provided on the habitat of the Australian moth, Phalaenoides glycinae (Lewin, 1805) (Lepidoptera: Noctuidae: Agaristinae) in the Sydney district, New South Wales, Australia. A small population of larvae were observed feeding on the leaves of the native mistletoe Amyema gaudichaudii (Loranthaceae) within the Cumberland Plain Woodland habitat in western Sydney, New South Wales. These data are recorded because of the near event of the site being cleared for residential development and the larval host record is apparently new.

Notes on the host plants of Bethelium Pascoe, 1866

(Coleoptera: Cerambycidae) from Australia

by

TREVOR J. HAWKESWOOD

Abstract - The larval host plants are recorded for Bethelium eburatum (Pascoe, 1863) and B. signiferum (Newman, 1840) (Coleoptera: Cerambycidae: Cerambycinae) from Australia. The new hosts are both Eucalyptus species (Myrtaceae). These records are in general accordance with the host plant selection noted previously for B. signiferum and other members of the genus. Host plants of all known Bethelium species are reviewed.
