ST. HELENA. 
*N. horridus, Woll. — The largest of the three species ; a black 
Beetle, a quarter of an inch in length, and a true native of the 
indigenous plants on the high land. 
squamosus, Woll.— A curious little dark brown Weevil, 
less shiny than the former, about an eighth of an inch in length, 
found amongst dry leaves and sticks on the elevated parts of the 
Island, and figured in the Journal of Entomology for Dec. 1861, 
pi. xiv. fig. 3. 
"N. asperatus, Woll. — A dark brown, mud-coloured Beetle, 
about the same length but thinner than the last, very common 
amongst dead oak leaves and rotten branches that have fallen on to 
damp ground, at an altitude of 2000 feet above the sea, at Oak 
Ban k, Plantation, &c. Mr. Wollaston considers these species 
to be unmistakably indigenous at St. Helena, being without doubt 
amongst the most characteristic of the aboriginal forms. 
SUB-FAM. TRACHYPHLCEIDES. 
Trachyphloeosoma, Woll. 
Mr. Wollaston writes of this genus : “ The insignificant little 
brown Curculionid which is manifestly one of the most indigenous 
of the St. Helena Coleoptera, has so much the primd facie appearance, 
in its short oval outline and the mud-like scales and setse with 
which it is clothed, of a minute Trachyphlceus that it required a close 
examination to convince me that it should not be referred to that 
group. When carefully inspected, however, it will be seen to have 
many essential points of difference ; for not only is its rostrum more 
abbreviated and conical, and truncate (instead of triangularly scooped 
out) at the tip, but its scrobs is likewise more bent downwards (and 
that very suddenly) beneath the still smaller and less prominent eye, 
from which, consequently, its lower edge is much more remote ; its 
antennae also are a trifle less incrassated, and inserted appreciably 
nearer to the apex of the rostrum ; and its feet have their third joint 
less broadly bilobed, and their claws a little more developed. Un 
the whole, I should say that it had more in common with my 
Madeiran genus Scoliocerus than with Trachypllmts proper ; never- 
theless, the position of its rostral grooves and its less curved scape 
will of themselves suffice to separate it therefrom.” 
*T. setosum, Woll.— A dull muddy-brown Beetle, about one-
