the females, also, exhibiting a tendency to similar 
irregularities. 
The species of Trogophlueus, — diminutive, cylin- 
drical, dull-black, pubescent insects, with very short 
tarsi, — occur in mud-banks and wet places, and have 
usually a deep impression at the back of the thorax. 
Syntomium ceneum, a small, metallic, “ stumpy ” 
beetle, very strongly punctured and slow of foot, 
and with three apical joints of its antenna) suddenly 
thickened, may be found under dead leaves in sand- 
pits, and also in moss in woods. Lastly, the rare 
Acrognathus and Delects ter, larger, rufo-testaceous 
species, live in very wet places, in rotting leaves at 
the edges of ponds ; the former is very sluggish, and 
seems swollen with the water in which it soaks, but 
the latter flies readily, and runs with great swiftness. 
The Hohaliinje have five-jointed tarsi ; the pro- 
thoracic spiracles hidden ; the thorax membranous 
beneath, behind the anterior coxae; the antennae 
inserted under the lateral margin of the forehead, 
which margin is not elevated ; the anterior coxae 
almost conic and exserted, aud the posterior traus- 
verse ; the maxillae armed with a horny book at the 
apex; the elytra reaching beyond the metathorax, 
and rounded at the outer hinder corners ; and two 
ocelli on the middle of the head. They are mostly 
somewhat depressed, with long, slender antennm ; and 
live in wet places, under seaweed, stones, aud bark, 
and in flowers. 
The species of Antliophagus, Geodromicus, and 
Lesteva, on account of their long slender legs, long 
elytra, and somewhat heart-shaped thorax, present 
considerable resemblance to certain of the smaller
