Observations on the various Insects 
habits maize, in the spikes of which it has been found alive in 
this country, but which I have frequently taken out of bread in 
London. It is a native of Portugal, and no doubt is imported 
wiih the corn. This Coleopterous insect belongs to the 
Family Tenebriomd.t; and the Genus Uloma: the species 
has been described by Fabricius * as the 
12. Uloma cornuta. It is tawny-ferruginous, smooth, shining, 
and very finely punctured, elliptical, and slightly depressed. 
The male has a broad head, the sides of the clypeus are ddaled 
and form a winged margin, which passes across the centre of the 
black eyes ; betw een them is a pair of tubercles, and in front 
project the two curved-pointed jaws: in the female the jaws are 
small and the margin of the clypeus is simply ddated : antennae 
inserted under the clypeus not so long as the thorax, straight, 
slightly thickening to the apex, 11 -jointed, basal joint curved, 
2nd the smallest, the following more or less cup-shaped, the 
terminal one orbicular : thorax transverse-quadrate, the sides a 
little convex, the hinder angles acute : scutellum minute, semi- 
ovate: elytra not broader than the thorax, but long and elliptical, 
the margin a little reflexed. minutely punctured, with ten punc- 
tured striae on each, the 1st short : legs simple ; tarsi 5-jointed 
excepting the hinder pair, which are only 4-jointed : claws 2 : 
length If line, breadth 4^ of a line.f 
Trogosita Mauritamca — The Cadelle. 
The history of this beetle will complete my observations upon 
the insects which infest granaries and barns. It has evidently 
been introduced from the shores of Africa, in which country it is 
abundant, as well as in America, and has now spread itself over 
a great part of Europe, so that it is common in the south of 
France in the larva state, and makes verv great havoc among-st 
the corn locked up in granaries ; it also attacks dead trees, 
and even bread and nuts. No doubt the specimens found in 
this country of the T. Manritanicus have been imported amongst 
fruits or grain, but it is clear that they colonize occasionally, from 
the fact that Mr. C. C. Babington found them in the rotten floor 
of a malthouse in Cambridge. Mr. Kirkup also bred the beetle 
from a Spanish almond, in which it lived as a larva for 1.5 
months, after which it remained alive as a beetle for 21 months, 
making a period of 3 years, besides the time it had been in 
existence previous to its being discovered in the almond.J 
The larvae are called Caddie in the south of France, and they
