I have been unable to find a consistent difference between the calling songs of tessellata and veyseli, but these species are completely aliopatric in western Europe and easily separated morphologically. See p. 4 for definitions of the terms 'echeme', 'syllable', 'macrosyllable' and 'microsyllable'. 1 Song consisting of a long series (lasting at least 10 s) of uniformly short echemes or single syllables, in either case lasting less than 0-5 s and repeated regularly at the rate of at least 1/s (Figs 36, 37, 41, 42,44) 2 - Song consisting of irregularly repeated syllables, or of echemes repeated less frequently than 1/s and at least some lasting more than 0-5 s (Figs 38, 39, 40, 43,45,47,48) 8 2 Song consisting ofechemes of 2-10 syllables 3 - Song consisting of ungrouped syllables 7 3 Echemes composed of a single macrosyllable fol- lowed by several microsyllables (Figs 123, 125) stricta - Echemes composed of 2 or more macrosyllables with no microsyllables 4 4 Echemes composed of 2 macrosyllables 5 - Echemes composed of 3 or more macrosyllables .. 6 5 Echeme repetition rate less than 4/s; syllable repeti- tion rate less than 15/s (Figs 103-105) .. intermedia - Echeme repetition rate more than 4/s; syllable repetition rate more than 15/s (Figs 99-102) sepium 6 Echemes usually composed of 5 or fewer syllables (Figs 49-66) albopunctata - Echemes usually composed of 6 or more syllables (Figs 67-75) sabulosa 7 In western Europe occurring only in eastern Austria veyseli - Not occurring in Austria tessellata 8 Song consisting of disyllabic echemes grouped into short sequences of about 2—4 echemes (Fig. 43) sepium - Song not consisting of disyllabic echeme
