This is so typical for Ophioneurus signatus, that when 
having a specimen for examination, a mistake cannot be 
made. 
None of the European forms known to me have any- 
thing similar. 
Girault finally describes a genus Lathromerella, Mem. 
Mus. Queensland I, II, which is evidently very closely re- 
lated to Ophioneurus. 1 have not been able to obtain 
possession of the description, even by corresponding with 
Girault, but as in Mitt. a. d. Zool. Mus. in Berlin VII Bd. 
2 II p.149 he describes a European species Lathromerella 
germanica, and as this species to a very great extent agrees 
with the two Danish species, I am inclined to maintain 
that Lathromerella is only a synonym of Ophioneurus, 
although there may yet be reasons to place our one Danish 
species and Lathromerella germanica as a seperate genus, 
but on this point at present | am not able to discuss 
further, until the international means of intercourse once 
more are established after the war so that it is possible to ob- 
tain foreign literature. One point, however, is certain: that 
Ratzeburgs genus Ophioneurus is a good and typical genus, 
which is hereby raised to rank and honour equal the other 
genera in the large kingdom of the Chalcidids. 
The following is the description of the genus: 
Antenne 9 jointed, consisting of scape, pedicellus, 
annellus, and 6 jointed clavus. Head triangulate almost oval, 
mandibles with three teeth, antenne inserted at mouth, 
eyes large round with a slight hollowing on the inner 
side, ocelli in a very wide triangle, abdomen as long, as 
head and thorax together. 
Of this genus three species are known at present in Eu- 
rope, two of which have been found in Denmark. They 
can be distinguished by the following characters:
