The sound of Ducetia japonica Thunberg consists of three stages, initial stage, low tide stage and high tide stage. In sound spectra of song, the main peak freguency of low tide stage is 1. 4 kHZ, that of high tide stage is 1. 8 kHZ. The secondary peak freguency of loW tide stage is 2. 4 kHZ, that of high tide stage is 1. 6 kHZ.

We obtained the first records of Sciobia (Thilptoblemus) natalia in Europe after a single record from Algeciras (Spain), about one century ago. We found the species in Tarifa, Benelup-Casas Viejas and Alcal\á de los Gazules (C\ádiz province) in plots with open land and herbaceous vegetation of wasteland, cattle states, edges of agricultural land, and hedgerows of pathways and local roads. The species may be common locally, in late spring. It may coexist with Sciobia (Thliptoblemus) caliendrum although the later presents a wider ecological spectrum whereas S. (T.) natalia prefers dense vegetation in more humid soils. Acoustic analyses indicate that the song of both species are very different, making field identification feasible. S. (T.) natalia may however easily go unnoticed among populations of the more conspicuous S. (T.) caliendrum. We discuss possible reasons why this species has gone unnoticed so far and factors that may pose at risk the maintenance of its populations.

There are 9 cricket species known from Romania belonging to the family Gryllidae. The ordinary stridulation of 7 species of those has been analyzed in this paper. The species belonging to the subfamily Gryllinae: Gryllus campestris, Acheta domestica, Melanogryllus desertus, Modicogryllus frontalis and Modicogryllus truncatus stridulate especially in the afternoon and in the evening, rarely during daytime, meanwhile the species Pteronemobius heydenii from the subfamily Nemobiinae stridulate only during daytime and especially by sunny weather, while the only species belonging to the subfamily Oecanthinae from our country fauna, Oecanthus pellucens, stridulate at night, very rarely during daytime (mostly in autumn). Details of the stridulatory vein and identification criteria for the studied cricket species are presented in this paper; also we have annalysed the spectrograms and the oscillograms for the ordinary stridulation of the 7 species. The species Modicogryllus truncatus, collected at Mărăşeşti, is a new report for Moldavia.
