24S [March 
The following specific points also occur to me among tlie Eydradephaga and 
Philhydrida : — 
Our rejected Eydropori, minutissimus, and lisulcatus (sjn. of our equally re- 
jected unistriatus) are still credited to us. H. derelictus, Clark, is (as in Schaum) 
attributed to erythrocejphalus, Linn. ; but, from an examination of Dr. Power's 
original specimen, I must say I tliink this assertion of identity cannot be sustained. 
My suggestion (Ent. Ann., 1869) that Agahus nigro-wneus, Er., should be re-named 
Erichsoni, in cpnsequence of the priority of the same Marshamian name, is here 
anticipated. Helophorus dorsalis, Marsh., is reinstated, but dorsalis, Muls., is 
erroneously attributed to it as a synonym. The latter has long been re-named 
Mulsanti by me, a correction adopted by Mr. Crotch. Ochthehius rufimarginatus, 
St., Er., is (erroneously, as I think) considered a var. of 0. hicolon. Germ. 0. 
hibernicus, Curtis, is exalted over the Stephensian pundatus ; — De Marseul and 
Stein separating the two, and giving the former as a syn. of lifoveolatus, Waltl., a 
species not yet recorded as British, as far as I know. In Wat. Cat. they are given 
as identical, punctatus having the priority. Hydrcena concolor, Watei'house, Ent. 
Mag., I, 1833, 293, not appearing in the synonymy of Wat. Cat., is given as a dis- 
tinct species. From an examination of Mr. Waterhouse's notes, I find that this 
insect is H. riparia, apparently immature, and accidentally omitted from his Cat. 
Among the Brachelytra I find the following : — 
Ischnoglossa corticalis, Steph., and Mycetoporus hrunneus, Marsh., respectively 
recognised as identical with I. rufo-picea, Ktz., and M. ruficornis, Ktz., are never- 
theless deposed in favour of the two latter names, in spite of the evident priority 
of the former. Aleochara Kirhyi, Steph., erroneously coupled with grisea, Ktz., — 
the algarum of Fauvel (really identical with and posterior in date to the former) 
being erroneously given as a distinct species. Oxijpoda nigrofusca, Waterhouse, 
seems to me to require re-naming, on account of the prior insect of that name of 
Kirby and Stephens, which, however, appears to be a synonym of 0. longuiscula. 
For the former species I accordingly propose the name " Waterhousei." Homalota 
planifrons and platycephala of Waterhouse are erroneously given as distinct species : 
Mr. Waterhouse withdrew the latter name, originally proposed by him for his 
insect, on account of platycephala, Thorns. The wind-bags, Homalota picea, Mot- 
Bchulsky, and Euplectus Easterbrookianus, Leach, are again inflated. Will no one 
puncture them ? Gyropihcena Poweri, Crotch, Stenus annulatus, Crotch, Lathrobium 
JoAisoni, Crotch, and HomaUum crassicorne, Matth., are omitted. Bryoporus Hardyi 
is inserted under the genus Mycetoponis, though Bryoporus is recognized as a dis- 
tinct genus. Quedius microps, Grav., Stett. Ent. Zeit., 1847, is accredited to 
Britain. 
Baphirus (Quedius) nigricornis, Holme, Trans. Ent. Soc. iii, pt. 2, 184-2, p. 127j 
and HomaUum mesomelasy Holme, 1. c, 1841, 128, are respectively given as good 
Bpecies. Neither of them is accounted for in the synonymy of Wat. Cat., though 
Philonthus sericeus, Holme, is therein recognized. The Quedius is stated by Holme 
to be barely 2 lines long, and to be distinguished from all others of the genus, 
except fuscipes, by its black legs and antennas. Stephens' exponent of it appears 
to be a very small black form of Q. fulgidus. The HomaUum is by Holme himself 
stated to be possibly a highly coloured variety of H. sordidum, Kirby, Steph., — the 
type of which insect appears to be Plulorhinum liixmile, Er., and wliich is repre- 
sented by if. iopterum in Steph. Coll.
