individual from the Rio Naranjo, and another from San Gerénimo, are slightly smaller 
and paler, but can scarcely be considered distinct. 
2. Myllena fragilis. 
Densissime subtilissimeque punctulata, brevissimeque sericeo-pubescens, subopaca, fusca, pedibus palpisque 
testaceis ; antennis elongatis, articulis basali et apicali testaceis. 
Long. circiter 24 millim. 
Hab. Guatemata, San Gerdénimo (Champion). 
The individuals of this species are excessively similar to those of the European J. 
intermedia, but they do not quite agree; the antenne of the two are nearly similar, 
but are a little more dilute in colour in M/. fragilis, especially towards the extremity, 
and the terminal joints are rather stouter in proportion to their length. The colour of 
the American insect is probably more dilute, its punctuation a little finer, and the base 
of the thorax is not sinuate on either side. In IZ. fragilis the antenne area good deal 
longer than they are in WZ. mollis. 
Two badly preserved individuals have been found. 
3. Myllena debilicornis. 
Densissime subtilissimeque punctulata, brevissimeque sericeo-pubescens, pallide fusca; antennis, palpis pedi- 
busque testaceis, illis elongatis gracilibus. 
Long. circiter 24 millim. 
Hab. Guatemata, San Gerénimo (Champion). 
This species is again very closely allied to the two preceding, but is readily distin- 
guished by the very elongate and slender, pale antenne, which are fully as long as head, 
thorax and elytra. There is a scarcely perceptible sinuation on each side of the base 
of the prothorax, just enough to render the hind angles rectangular. The sinuation 
of the hind margin of the elytra is about as great as in I. intermedia. 
Only one individual has been found. 
4. Myllena obtusa. 
Densissime subtilissimeque punctulata, brevissime sericeo-pubescens, fusca, pedibus testaceis; prothorace 
angulis posterioribus fere obtusis, elytris quam hic haud longioribus ; antennis sat elongatis, subgracilibus. 
Long. circiter 23 millim. 
Hab. Guatemaa, Torola 1000 feet (Champion). 
Antenne longer than head and thorax, rather stout for this genus, in colour not 
paler than the body; terminal joint elongate, scarcely paler than those preceding. 
Thorax with the base slightly rounded, and no sinuation at the hind angles, so that 
these are slightly obtuse. FElytra slightly sinuate at the outer angle. 
This insect is closely allied to the European I. glauca, Aubé, but is rather smaller 
and darker in colour, and has the hind margin of the elytra less sinuate at the outer 
angle. Only one individual has been found.
