The species of Hoplismenus appear to be uncommon in Britain. 
Some thirteen species are known on the Continent, most of which 
ought to occur here. Ichnewmon exornatus, Wesm. (= pictus, Gr.), 
Platylabus dimidiatus, Gr., P. errabundus, Gr. (= albinus, Gr.), 
were all included in Hoplismenus by Desvignes ; his H. semirufus, 
described in the B. M. catalogue, is also a Platylabus. Five 
species of this genus are known to be parasitic upon butterflies. 
H. perniciosus, our commonest species, was bred by Giraud from 
a Satyrus Mera* pupa, and Brischke bred H. bidentatus, Gr. (var. 
of perniciosus, teste Marshall), from Aspilates  strigillaria. 
Kriechbaumer says H. aulicus is probably attached to a willow- 
or sallow-feeding larva. He also met with the female, which 
Tischbein has described; making a new genus (Hybophorus) for 
this species amongst the Ichnewmones amblypygi near Trogus 
(Stett. Ent. Zeit. xxxvi. 280).

Our two species of Hxophanes are fairly common, and they are 
very liable to be mistaken for similarly-coloured species of
