divided into four families, the Rkinomaceridse (or 
Nemonychidse), Platyrrhinidse (or Anthribidse) , Cur- 
culionidse, and Scolytidse. 
The Rhinomaceeim are distinguished by having 
the maxillary palpi of the ordinary form and flexible, 
the labrum distinct, and the antennas straight; the 
anterior coxae are conical, and the pygidium is covered 
by the elytra; the rostrum is long and enlarged in 
front ; the antennae are long and slender with the club 
long, loose, and scarcely marked, and the scrobes are 
absent or superficial ; the family appears to bear a 
strong affinity to the Mycterina, which conclude the 
Heteromera. 
Rkinomacer attelaboides is a slender and elegant 
insect, clothed with rather long greyish pubescence. 
M. Perris has observed that its female deposits her 
eggs in the catkins of the male flowers of the pine, of 
which the presence of the larva prevents the expan- 
sion. This species is found not uncommonly in cer- 
tain parts of Scotland ; it frequents Conifers, and its 
male is remarkable for possessing two little tufts of 
yellowish hairs on the second and third abdominal 
segments. 
The Pi-atyuriiynida: (or Antheiuid.e) have the an- 
tennas eleven-jointed, and terminated by a short, 
abrupt three-jointed club, the eyes not notched, short 
transverse scrobes to their wide, deflexed rostrum, the 
pygidium not exposed, and the second joint of the 
tarsi bi-lobed; they differ from the Rkinomaceridse 
(which, in many points, they closely resemble) by 
having the anterior coxae globose, and the pygidium 
more or less uncovered. The males are usually dis- 
tinguished by the superior length of their antennas.
