Inhabits all the islands of the Madeiran Group, except (apparently) 
the Northern Dezerta, on which it has not yet been observed. In 
Porto Santo (especially on the Ilheo de Baixo, adjoining it), as well 
as on the Southern Dezerta, it is common during the spring. On the 
Dezerta Grande it is rare; and in Madeira proper it is principally 
attached to the sylvan districts of a high elevation. It occurs lke- 
wise in the Canary Islands. 
Genus 6. LEISTUS. 
Frohlich, Naturf. xxviii. 9 (1794). 
The genus Leistus (the discovery of which in these islands is of 
subsequent date to the publication of the Insecta Maderensia) may be 
at once known by the extremely slender and elongated palpi of the 
insects which compose it, and by the curious structure both of their 
upper and lower jaws,—the former of which are unusually dilated 
towards their outer base, whilst the latter are armed with a series of 
large spiniform processes (mounted with strong sets) externally. 
The mentum has a broad and subemarginated tooth in the centre of 
its (shallow) excavation ; and the ligula is narrow and immensely 
produced, being also acutely tricuspid at its apex. Like so many, 
however, of the endemic (Madeiran) representatives of European 
genera, the Z. ellipticus differs slightly, even in some of its struc- 
tural details, from the normal members of the group. Thus, its 
upper lip is more rounded in front than is the case in its more 
northern allies, and its paraglosse are obsolete,—or, at least, are not
