one or two midescribod species, but I should be sorry to describe them 

 without UKikiiiy a mucli more careful study of the genus than I have 

 been able to do; the table given below must, tlierefore, be considered as 

 more or less provisional ; the species have the antennae ten-jointed, and 

 all the tarsi four-jointed. 



I. Antennae with the seventh joint evidently loiifrer, and 

 a little tliicker than the sixth, joints 8-10 forming a 



tjnidmd club H. LONGICOBNIS, Patfk. 



II. AntPtniiv with the seventh joint not longer or 



thicker than sixth, sometimes shorter. 

 i. Auteuna^ dark, or dark ferruginous red, with 

 base sometimes lighter; elytra dark reddish- 

 brown, blaek-brown, or black ; club gradual. 



1. Fuscous ; male with the first joint of anterior 

 tarsi stronpfly dilated ; antennte reddish or red- 

 dish brown with base li^'-hter H. L*:viuscULrs, Mann. 



2. Black; male with the first joint of anterior tarsi 



not 01- scarcely dilated ; antennae nearly black . H. GA'ULrM, Heer. 

 ii. Antennse entirely yellow testaceous. 



1. Klytra dark. 



A. Ciub rather stroni;ly marked ; antennae 



shorter; a|)ex of hind body almost coneolorous. H. eEMINULCM, £">•. 



B. Club gradual ; antennae longer; apex of hind 



body broadly testaceous H. APiCAils, Biis. 



2. Elytra red or reddish. 



A. S'ze very small ; apex of hind body not 



sharply testaceous H. PTTNCTTTM, Mots. 



B. S ze larger ; apex of hind body broadly and 



sharply testaceous H. DISCOIDEUS, Er. 



K. long-icornis, Payk. {amminatimi, Marsh, rufipps, Steph., 

 nigripes, Steph,, yarvula, Steph., granulum, Grav., (jlobulus, Lac, 

 agaricina, Steph.). Very convex, subglobose, shining black, with the 

 margins of thorax broadly testaceous, and the elytra pitch-black, or 

 lighter or darker reddi.sh brown, with the margins lighter, pubescence 

 fine and scanty ; head narrower than thorax, smooth, antennae long, 

 longer in male than in female, lighter or darker pitchy testaceous, seventh 

 joint evidently longer and thicker than sixth (appearing, in male, to form 

 part of the club), club gradual, longer and more slender in male than in 

 female ; thorax very short, strongly narrowed in front, almost as broad 

 behind as elytra, smooth, posterior angles rather marked ; elytra 

 transverse, one and a half times as long as thorax, spaiingly pubescent, 

 very finely and sparingly punctured ; hind body retractile, very finely aiul 

 sparingly punctured, strongly narrowed behind, apex often pitcliy, or 

 pitchy testaceous ; legs pitchy red or pitchy testaceous. L. 1^ mm. 



]\Iale with the seventh ventral segment deeply and angularly emar^i- 

 nate, sixth segment prolonged in an obtuse arc over the middle of seventh, 

 segment of armature projecting, rugosely punctured. 



In haystack refuse, moss, dead leaves, decaying seaweed, &c. ; also by sweeping 

 and beating ; very common and generally distributed throughout the kingdom.
