Aphodius. } LAMELLICORNIA. 33 
circular, with strongly raised front margin; thorax rather thickly and 
finely punctured, the punctuation consisting of large and small punctures 
intermingled ; elytra with fine and finely crenate striz, interstices flat, 
rather finely but distinctly punctured in irregular rows, colour very 
variable, lurid-testaceous with dark, more or less longitudinal, markings, 
sometimes entirely black, and occasionally simply testaceous with the 
strie dark ; between these two extremes every variety oceurs ; legs black 
with tarsi ferruginous, or pitchy, or sometimes entirely reddish. 
L. 6-9 mm. ; 
Male with the spur of the anterior tibize obtuse at apex and somewhat 
inflexed ; in the female it is acuminate. 
In dung; generally distributed throughout the greater part of the kingdom, but 
somewhat local in certain districts; the black variety is rather uncommon. 
A. rufipes, L. (capitatus, De G.; Acrossus rufipes, Muls.). Elongate, 
oblong, subparallel, moderately convex, almost subeylindrical, pitchy 
black, or pitehy reddish-brown, with the forehead and middle of thorax 
often darker, and the front of head and sides of thorax lighter ; antenn 
and palpi clear ferruginous or reddish-brown; head flat, very finely 
punctured, semicircular in front with distinct raised margin ; thorax ex- 
ceedingly finely punctured, almost smooth on dise, with larger punctures 
at sides and anterior angles ; scutellum smooth; elytra long, scarcely 
dilated behind, with distinct, but rather feebly crenate striz, interstices 
flat, extremely finely punctured ; under-side and legs reddish or reddish- 
brown. L. 10-12 mm. 
Male with the metasternum slightly impressed in middle, and the 
forehead even; female with the frontal suture distinet, and with the 
clypeus obsoletely raised in middle. 
In dung ; common and generally distributed throughout the kingdom. 
A. depressus, Kueg. (nigripes, Gyll.; atramentarius, Er. ; Acrossus 
depressus, Muls.). Oblong oval, moderately convex, but somewhat 
depressed on disc, shining black, unicolorous, or with the elytra bright 
red ; head flat, finely punctured, semicircular in front, with distinct 
raised margin, antenne black, palpi clear red; thorax finely but dis- 
tinctly punctured, the punctuation consisting of larger and smaller 
punctures intermingled ; scutellum punctured at base ; elytra somewhat 
dilated at sides, with finely crenate striz, interstices flat, comparatively 
distinctly punctured ; legs black with tarsi ferruginous. L. 6-8 mm. 
Male with the forehead even, and the thorax larger and more finely 
punctured than in female; in the latter sex there is a trace of the 
central frontal tubercle, which perhaps confirms Thomson’s observations 
regarding A. porcus (see page 26). 
In dung ; somewhat local, but widely distributed throughout the kingdom as far 
north as the Orkney Islands; the form with red elytra is the typical form, and 
appears to be very rare as British.
