antenna and orificia and, above all, the male genital segment. 
The transitions between species with five-jointed and four- 
jointed antenne are quite gradual. In some species the suture 
between the second and third joints is fairly distinct, in others 
it is hardly perceptible, sometimes disappearing only on the 
inner side of the joint or vanishing altogether as in A. her- 
mannsburgi. In no species I have seen a quite normal articu- 
lation with free mobility between these segments. We find a 
quite analogous structure of the antennz in the allied genera 
Eumecopus Dall. and Poecilometis Dall. In both these genera 
there are species with five-jointed and with four-jointed an- 
tenne, owing to the second and third joints being either more 
or less distinctly separated or fused together. Kirkaldy (Cat. 
Hem. I, p. 189) founded the “subgenus, if not genus” Eurono- 
tias on the species of Poecilometis with five-jointed antenne. 
Why he did not make the same subdivision in the genus Eume- 
copus is hard to understand. Euronotias is quite unnatural 
and untenable even as a subgenus, as both in Poecilometis and 
Eumecopus some species with four-jointed antenne are much 
more closely allied to certain species with five-jointed antennz 
than to each other. 
Theseus parvulus Westw. 
In his revision of the Pentatomidae described by Westwood 
in the “Hope Catalogue,” Distant places Halys parvula Westw. 
in the genus Spudaeus Dall., but from the figure he gives of 
the type it is clear that it belongs to Theseus Stal. 
Kirkaldy proposed the new name Austromalaya for Spu- 
daeus, which is said to be preoccupied by Gistl. From what I 
have gathered about that monstrous literary product “Natur- 
geschichte des Thierreichs fiir hohere Schulen bearbeitet von 
J. Gistl” few of his very numerous new names are properly 
founded. They seem to be nomina nuda massed together in 
the 16 pages forming the introduction to the book and mostly 
proposed quite arbitrarily without real grounds for old, well- 
known genera. I believe that most of these names have been 
undeservedly included in Waterhouse’s “Index zoologicus.”
