HOLOPARAMECUS. 627 
1. Holoparamecus singularis. 
Holoparamecus singularis (Beck), Belon, Rev. Ent. Fr. 1897, p. 160*; 1900, p. 92°. 
Hab. Mexico, Jalapa (Hége).—Evurope; Asta; AFRICA. 
The single specimen from Jalapa quite agrees with a British exponent of this 
species. It has been previously recorded from North America, but, according to Fall, 
erroneously. The synonymy is extensive and to a considerable extent doubtful. It is 
given in detail by Belon!. 
2. Holoparamecus pumilus, sp. n. 
Angustus, convexus, pallido-testaceus; oculis haud coloratis, in medium capitis laterorum sitis, a prothorace 
remotis ; prothorace ante basin parum discrete impresso. 
Long. 17 millim. 
Hab. Mexico, Chilpancingo in Guerrero 4600 feet (H. H. Sinith). 
This little insect is remarkable on account of the apparent absence of eyes, which 
are, however, represented by a pallid prominent space on each side of the head placed 
near the antenna and far from the thorax. It has only ten joints to the antenne, the 
tenth being large and cyathiform, and of itself forming the club. The head is long 
and narrow. ‘The thorax is a little narrowed behind, about as long as broad; it is 
rather convex, much depressed at the base; but there are no distinct impressions, 
though in certain lights a very short line is visible extending a little forwards from the 
base near each hind angle. ‘The elytra are convex, with a well-marked sutural stria. 
The surface is very shining. One specimen. 
M. Belon has established the genus B/umenus for a small Brazilian species having 
10-jointed antennz, with one joint to the club. Except in this respect, our insect 
appears to have little relation to B. villiger, and I think it better to treat it as a 
Holoparamecus. 
3. Holoparamecus brosciformis, sp.n. (Tab. XIX. fig. 1.) 
Elongatus, angustus, rufo-testaceus, antennis pedibusque testaceis, politus ; oculis magnis, prothoracis marginem 
fere attingentibus ; prothorace elongato, ad basin fortiter angustato, ante basin in medio et utrinque 
profunde foveolato. 
Long. 1% millim. 
Hab. GuareMa.a, San Gerénimo (Champion). 
This is a very distinct species of the subgenus Calyptobium, the antenne being formed 
of eleven clearly separated joints. ‘The surface is highly polished, there being only 
very feeble traces of punctuation. ‘The antenne have the ninth joint transverse; the 
club is 2-jointed, the first of the two joints being large, transverse, the terminal joint 
much smaller, transverse, obliquely truncate. The thorax is rounded at the sides in 
front and strongly narrowed behind, deeply impressed in front of the base, there being 
a fovea at each hind angle and a large deep depression between them, which shows
