of this remarkable insect were found together with Aépus 
Robini (hence the generic name) under stones that were 
deeply submerged during flood-tide. In Tijdschr. v. Ent. 
1880 Signoret copied his original description (somewhat 
altered) and figured the insect. 
Signoret was quite uncertain, as to where this new 
hemipteron should be placed systematically, although he 
found it resembling a Cerafocombus muscorum. Initiated 
by Bergroth Lethierry and Severin in their Cat. Gen. T. 
III 1896 raised the new genus to family rank and placed 
it between the Velocipedide and Ceratocombide. O. M. 
Reuter in Bem. neues Heteropterensyst. 1912 even erects 
a new „phalanx“, Aépophiliformes, and places it between 
ph. Acanthiiformes and ph. Gerriformes, while he puts 
the family between Leptopodide and Gerride. It is quite 
evident that the raising to family rank is fully justified, 
but the systematical place of the family must still be 
regarded as somewhat doubtful. 
I am now able to add a new genus, Mendocinia (allu- 
ding to its patria) to the family. This new genus is 
evidently not far removed from Aépophilus systematically, 
but a series of distinctive characters gives it a particular 
place apart from Aöpophilus. Signoret’s description of 
this genus fails in giving information as to comparison 
relating some striking features in Mendocinia, which for 
an instance has the eyes hairy (quite unusually in Hemi- 
ptera), and the opening of the odoriferous canal applied 
at the end of a protruding, iree tube or protuberance; 
but Mr. Bergroth has kindly informed me that the eyes 
are also distinctly hairy in Aépophilus, while this genus 
lacks the protruding tube for the odoriferous canal. 
The new genus and species are founded on a single 
specimen, which for some years has been preserved in 
alcohol together with a multitude of specimens af Bem- 
bidium, Tachys, Ochthebius, Heterocerus and other coleo- 
ptera that are mostly found in damp localities, along the
