204 LIVERPOOL BIOLOGICAL SOCIETY. 
Helophorus aquaticus, L. Abundant. In my series I 
cannot find any of the apparently common var. equals, 
Thoms. 
Helophorus Mulsanti, Rye. The specimen recorded in 
my former article under this name is, I find, H. enevpennis. 
Fowler records Mulsanti as being taken commonly here 
by Mr. Crotch. 
Helophorus griseus, Thoms., = HA. affinis, Marsh. 
Occasional. 
Helophorus granularis, Thoms., = H. brevipalpis, Bedel. 
Abundant. 
Helophorus eneipennis, Thoms. Altcar Rifle Ground 
(F. Archer). I have taken it abundantly in rejectamenta 
brought down the Alt after heavy rain; but all the speci- 
mens are of the normal type. 
Helophorus arvermcus, Muls. I have a specimen taken 
some eight or nine years ago among granularis. 
Helophorus dorsalis, Marsh. Altcar Rifle Ground (F. 
Archer). 
Hydrochus angustatus, Germ. Freely in clay-pits near 
Westminster Road (F.K.); Leasowe (R.W.); Liscard 
(J.W.H.). 
Octhebius margipallens, Latr. Taken sparingly by Mr. 
Chappell in a drain near Moreton Station. 
Octhebius pyameus, F. Moreton (J.W.E.). 
Octhebius bicolon, Germ. Abundant. 
Octhebius rufimarginatus, Steph. I took a pair of this 
species on Bidston Marsh, in 1882. 
Hydrena riparia, Kug. I have taken several specimens 
near Leasowe. 
Cyclonotum orbiculare, ¥. Common on the weedy banks 
of ponds, and at the mouth of the Alt at Hightown. 
Spheridium scarabeoides, L. Abundant in dung.
