on the Genera Holoparamecus Curtis, §c. 235 
‘“‘oblong, depressed, antennze 10-jointed, club 2-jointed, thorax 
obcordate, tarsi 3-jointed.” In the meantime Signor Villa had 
introduced into his Catalogues of Europzean Coleoptera, a genus 
amongst the Xylophaga, to which he first gave the name of Calyp- 
tobium, then that of Amphibolonarzron, Porro, with his own name as 
a synonym, and then again that of Calyptobium, with the name of 
Latrinus of Waltl as a synonym; all these names appear to have 
been unaccompanied by any description. In 1843, however, M. 
Aubé, whose devotion to the minute Coleoptera is so well known, 
published a memoir on the genus Calyptobium in the Annals of 
the Entomological Society of France, describing four species, and 
giving a series of details of the parts of the mouth, &c. ; the legs, 
3-jointed tarsi, labrum, mandibles, maxillee, and entire habit agree- 
ing with Mr. Curtis’s figure of his Holoparamecus, with which M. 
Aubé was unacquainted, but representing and describing the an- 
tenne as 11-jointed, and also describing and figuring the lower 
parts of the mouth overlooked by Mr. Curtis, and of which the 
labial palpi, from the very large and nearly globular shape of the 
middle joint, and the smaller triangular terminal joint, as well as 
the 3-jointed simple tarsi, entirely confirm the relationship of the 
genus to Latridius and Mycet@a. Of the four species described 
by M. Aubé, Calyptobium Ville is found abundantly near Milan ; 
C. caularum was taken by the Marquis de la Ferté Sénectére “dans 
du fumier de couches 4 melons,” as well as by M. Aubé himself 
“dans le fumier d’une bergerie” near Chateaureux, and by M. Lan- 
geland in a similar situation near Paris; M. Reiche had found it 
also in a box of insects from Senegal. C. Kunzet was found by 
M. Kunze “dans des champignons” received from Brazil; and C, 
nigrum, the fourth species, was discovered by Mr. Melly in his late 
journey in Sicily. 
M. Aubé considers the genus Calyptobium to approach closely 
to Monopis, an undescribed genus of Zeigler, founded on the 
Hypophlieus brunneus of Gyllenhal, but differmg in its 3-joimted 
tarsi, Monopis having them 4-jointed; he admits, however, that 
its place is uncertain, and that it might be convenient to unite it 
to the 7’rimera of Latreille, immediately in the neighbourhood of 
Cholovocera of Motschoulski. 
At the meeting of the French Entomological Society in the 
month of January, 1844, M. Guérin Meneville read a ‘note sur 
le genre Holoparamecus, et sur sa synonymie, et description d’une 
espéce nouvelle de ce genre,” affirming that Calyptobium is syno- 
nymous with Holoparamecus, and that H. depressus of Curtis is the 
Calyptobium Ville of Aubé. The supposed new species described
