TROGOPHLEUS SPINICOLLIS, 2%. S. 
Niger, nitidus, antennarum articulo primo, thorace, elytris pedibusque rufo-picets ; 
thorace transverso, viz cordato, postice angustato necnon utrinque impresso, angulis 
anticis in spinam productis ; elytris latis hoc duplo longioribus, grosse fere rugulose 
punctatis. Long. 13 lin. 
This curious insect, at once recognisable by the spined. anterior 
angles of its prothorax, may possibly be the type of a genus not at 
present characterized ; but the decidedly subulate apical joint of its 
maxillary palpi and its concealed scutellum point to Vrogophleus in 
preference to Ancyrophorus, to which geuus Dr. Kraatz (who considers 
it as a decidedly new species) thinks it should be referred. It is allied 
to T. scrobiculatus, Er. (arcuatus, Wat. Cat.), and riparius, Boisd., but 
has shorter and stouter antenne, a greater depth between the back of 
the eye and hinder margin of the head, a smaller and scarcely cordate 
thorax, of which the punctuation is very coarse and the dorso-lateral 
depressions are less conspicuous and not so complicated, and wider, 
longer, and much more coarsely punctured elytra. 
Antennz rather short and stout, being decidedly thickened towards the apex, 
and having the sub-apical joints almost transverse ; black, except the basal joint, 
which is pitchy-red. Head black, strongly punctured, with two lateral depressions 
below the vertex, meeting towards the front, and with the eyes not occupying so 
much lateral space as is usual in Trvgophleus. Thorax pitchy-red, shining, straight 
in front, with the anterior angles produced into a short but evident lateral spine ; 
contracted behind below the upper third; coarsely punctured, with a broad shallow 
depression on each side behind, leaving a central longitudinal space, a ridge along 
the posterior margin, and a small elevation on each side of the central space about 
the upper third smooth. Elytra pitchy-red, shining, double as broad and rather 
more than twice as long as the thorax, with a considerable scutellar depression and 
the trace of an abbreviated oblique depression between it and the shoulder; very 
coarsely and almost rugulosely punctured. Abdomen black, shining, very delicately 
and at the apex widely punctured. Legs pitchy-red. 
Taken by Mr. J. Kidson Taylor, of Manchester, under rejecta- 
menta of the river Mersey, on 9th August, 1868. 
ANISOTOMA SIMILATA, 2. Ss. 
Ovato-sub-globosa, ferruginea, nitida, prothorace levigato, antennis basi gracilibus, 
elytris striato-punctatis, punctis leviter impressis, strié a suturd quartad pone basim 
leviter arcuatd. Long. 1 lin. 
I should have hesitated in considering this (taken by myself at 
Shirley) as other than an extreme form of 4. badia, if Dr. Kraatz had 
not returned it to me as certainly distinct from that insect, and 
a good species. It is closely allied to A. badia, from which it
