Description of the male sex of HElota attenuata Rits

Autor: Ritsema Cz., C.

Publikováno v: Notes from the Leyden Museum, 35(3/4), 224-224

Helota attenuata belongs, together with Dureli, Moutoni and Helleri, to the group of Helota rotundata (see my „Synopsis” in Notes Leyd. Mus. Vol. XIII, p. 227). It is easily recognizable among these species by the coarse punctuation on the pronot

On some species of the genus Pachyteria from the old collection of Thomson

Autor: Ritsema Cz., C.

Publikováno v: Notes from the Leyden Museum, 12(1/2), 163-173

It will, I think, be already known to every student of exotic Coleoptera that Mr. James Thomson has parted with his beautiful collection and that it is now in the possession of Mr. René Oberthür, who in the last years increased his original collect

Three new species of the genus Helota

Autor: Ritsema Cz., C.

After a careful examination of not less than 14 representatives of the genus Zonopterus to which Hope’s description of flavitarsis ¹) is applicable, I hesitate to decide whether this is a very variable species as regards the form of certain parts
