XXXV. Notes on the Genera Holoparamecus, Curtis ; Am- 
phibolonarzron, Porro; Latrinus, Walél; and Calypto- 
bium, Villa. By J. O. Westwoop, F.LS. 
[Read 5th May, 1845.] 
In 1833, Mr. Curtis, in a paper published in the second number 
of the Entomological Magazine (p. 186), containing the characters 
of some undescribed genera and species indicated in his ** Guide 
to an Arrangement of British Insects,” described a minute beetle, 
measuring one-half a line in length, under the name of Holopara- 
mecus depressus, belonging to the family Corticaride, with the 
observation, “This insect appears to connect Scydmenus and the 
group I have called Corticaride, which has hitherto been included 
in the family of Engide. I took a single specimen in Norfolk 
many years since, and believe it to be granivorous.” Of this in- 
sect, in 1836, he published an excellent figure in his “ Generic 
Illustrations,” describing and representing the antennz as 9-jointed, 
the tarsi as 3-jointed and slender, the body depressed, with several 
impressions on the hind part of the thorax, and giving figures of 
the upper lip, mandible and maxille, having unfortunately failed 
in discovering the labium and its parts. Of its relations he thus 
observes: “ This very minute insect recedes from the typical groups 
of the Coleoptera, having only 9-jointed antenne, and triarticulate 
tarsi; it is, however, undoubtedly allied to Corticaria as well as to 
Latridius, with which it accords in the shape of the antennz, and 
in the numerical structure of the tarsi;” adding, that the genus 
Eutheia seems to strengthen the opinion, that this genus connects 
the Corticaride with the Scydmenide.” Of the habits of the genus 
he states, that he ‘“ took a single specimen of H. depressus many 
years since, running up the outside of a flour mill in Norfolk, 
which led me to believe that it fed upon grain; but I have since 
found several specimens amongst small pieces of decayed wood 
and bark, which came from Mexico I believe, and this renders it 
probable that it may live in the crevices and under the bark of 
trees, and also that it is, like many other insects, an imported 
species.” 
In preparing the “Generic Synopsis” of my “ Introduction to the 
modern Classification of Insects,” I had occasion toexamine an insect 
in my own collection, obtained from that of the late Mr. Haworth, by 
whom it was labelled Sierra Leone, and which agreed in all respects 
with Mr. Curtis’s figure, except that the antenne were 10-jointed ; 
I therefore introduced the genus into my list, with the characters
