ent. Zeit. 1866, pp. 251-262) : — Omaseus riigrita, var. rhceticus, Platysina 
vitrea (winged, perhaps distinct from Dejean’s species and = orinomumy 
Stepli.), Leirus torridus (111.) = Platysma angustata (Sclmeid. nec Duft.), 
Amara cvpricariay A. quenseli, and Bradycellus placidus (Gyll.) = B. cognatm 
(Schneid. nec Gyll.). 
Zahrus gibbus. Kiinstler notices the natural history of this species, and 
indicates the means to be employed for its destruction when it exists in in- 
jurious abundance. These consist in deep-ploughing at the end of May for 
the destruction of the pupae, and in collecting the beetles after their emer- 
gence in .June. Verb, zool.-bot. Ges. in Wien, xvi. pp. 646-646. ,
