Mosoleius | BRITISH ICHNEUMONS. 137 

betically as being doubtfully referred to it, in our last Catalogue by Mar- 
shall in 1872, really belong to the present genus, it may be well to here 
indicate their correct location. Of Zrvphon quadrisculptus 1 have already 
treated (Ichn. Brit. ii. +39); T. albocinctus, T. basalis, T. cephalotes, 7. 
flavomaculatus, T. laticeps, lineola, T. mitigosus, T. ridibundus and T. 
tricolor will be found a! aS Gr awicema. T. albovinctus, T. bidentatus, 
T. bisculptus, T. obscurus and T. trisculptus belong to Polyblastus; 7. 
chrysopus to Monoblastus ; and both 7° ca/cafor and T. fasciatus to Erro- 
menus. 7% d¢maculatus, Desv., is Euryproctus notatus, also here treated 
under Tryphon ; and closely allied to 7°. ochrostomus and 7. xanthostomus. 
T. involufor will be found under Ctenopelma and 7° 7ra/us is a Catoglyp- 
tus. 7. orbitals is an Ecclinops and 7% scofopferus raised to generic rank 
under Labrossyta. The remaining twenty-two species are referable to 
Mesoleius, as I present it, with the exception of 7° clypeator = Lissonota 
cylindrator (Ichn. Brit. iii. 204), 7. mz#édus = Meniscus agnatus (/.c. 232), 
7. quadrilineatus = Cryptopimpla blanda (/. c. 182, over which its earlier 
pagination gives it priority), and 7°. subspinosus = Phygadeuon grandiceps, 
Thoms., not yet otherwise known as British and doubtless misnamed. In 
fact I fear there has been a good deal of misnaming by our older British 
authors among these difficult insects; and I have, consequently, refrained 
from considering 7. calceolatus, Gr., 7. fulvilabris, Gr., and TZ. humilis, 
Gr., the types of which Pfankuch declares lost; as well as 7. flavilabris, 
Ste. Z. fulvilabris, Ste., and 7. zonafus, Ste., which are in similar plight. 
T. (Mesoleius) flavicinctus, T. (Perispudus) flavipes, T. (Alfkenia) integrator 
of which there is an example named by Grav. in Mus. Brit., 7. (Amorpho- 
gnathon) melanocerus, T. (Spudaea) nasutus, T. (Otlophorus) nigritarsus and 
T. (Mesoletus) nigrolineatus | consider misnamed as British by Desvignes 
and Stephens, all of whose specimens I have examined.
