Diestora. 
Diestota montana, n. sp.—Subdepressa, nigra, nitida, antennis palpis pedibus- 
que rufescentibus ; capite prothoraceque fortiter nec dense, elytris sparsim fortis- 
sime, punctatis ; abdomine fere impunctato. Long. 3 m.m. 
The coarse and sparing punctuation of the anterior parts and the shining 
impunctate hind body of this insect separate it widely from all its allies. 
The middle coxz are widely separated, and the mesosternum appears to be 
earinated, although, from the way in which my specimen is set, it is very difficult 
to be sure on the latter point. 
Waimea, Hawaii, by beating flowers at an elevation of about 3000 feet.

_ Diestota incognita, n. sp.—Subdepressa, subnitida, nigricans, palpis pedibus- 
que rufescentibus; capite fortiter densius prothorace minus distincte, elytris 
confuse crebrius, abdomine distincte, punctatis. Long. 2} m.m. 
This species resembles D. carinata, but its different punctuation, &c., readily 
distinguish it. 
The middle coxe are widely separated, and the mesosternum is without any 
traces of a carina. 
A single specimen was taken by beating flowers in a mountain forest on Hawaii, at an elevation of 
about 4000 feet. 
TB: 
MYLLANA. 
Myllena pacifica, n. sp.—Nigra, creberrime subtiliter punctata, subnitida, 
antennis pedibusque fuscis, illis articulo ultimo flavo; elytris prothorace haud 
longioribus ; antennis capite prothoraceque conjunctis longioribus. Long. 3} m.m. 
This insect resembles M. familiaris, Sh. The decidedly closer punctuation, 
however, the slightly longer antennz with the apical joint of a clear yellow colour, 
and the distinctly though slightly shorter elytra, render it incapable of confusion 
with its ally. From M. vicina and M. curtipes the unicolorous hind body dis- 
tinguishes it. 
I may observe here that several of my specimens of M. familiaris, Sh., 
are not less than 31 m.m. in length, and that (unless the size he gives is a mis- 
print) I must, by some accident, have sent unusually small specimens to Dr. Sharp, 
as I have only one example as small as that from which his description seems to 
have been made, 
A single specimen was taken on a flower of Freycinetia on Mauna Loa, Hawaii, at an elevation of 
nearly 4000 feet above the sea.
