AND HABITS OF RHIZOPHAGUS DEPRESSUS, FOWLER. 129 
found in flowers: for example, Jeligethes eneus, the tiny 
shining green beetle so abundant in the flower-heads of the 
Cruciferae and other plants where the larve feed, interfering 
with the production of seed; others live in putrefying 
organic matter, and others still, like Rhzzophagus, are in- 
sectivorous. 
: The genus Rhizophagus, which Sharp’? would refer to the 
Cucujidze rather than the Nitulide, numbers in Britain some 
ten species, which live below the bark of trees, where they 
make war on the Bostrichidz or bark-beetles. 
I quote Fowler’s® description of the imago, and his transla- 
tion of Perris’* description of the larva, of R. depressus. 
Imaco.—Bright rust red, with suture of elytra generally 
darker ; body depressed ; head of male large, about as broad as 
.% thorax, of female, narrowed, thorax longer than 
i broad, widest in front, thickly and very finely 
punctured; elytra with very finely punctured 
Saran ind je. SUT, first interstice with a row of widely- 
ea poe separated fine punctures ; second interstice 
ste ™ widened and irregularly punctured at base. 
Length, 2}-3}mm. 
Larva.—Length, 6 mm., rather depressed, and in the form 
of an elongated oval; head narrower than the prothorax; 
head and prothorax reddish, the base of the 
latter being whitish, and all the succeeding 
segments except the last are reddish for their 
basal half and whitish for their apical half; the 
head is long, almost elliptical, with two long im- 
pressions; the prothorax longer than the meso- 
or meta-thorax, and is rounded and narrowed 
in front; the last segment of the body is entirely 
ferruginous, and is furnished on its upper surface 
with two distinct tubercles; this segment behind 
is divided into two lobes, each of which 
nates in three strong teeth, on the under
