ZOOLOGY OF FERNANDO NORONHA.

is finely longitudinally rugulose, but this is very slight in the 
larger examples. The interstices of the elytra are closely and 
very finely punctured, each interstice having a line of rather 
closely placed, minute, shining tubercles. Epipleura of the elytra 
dull. Under flanks of the prothorax dull and closely longitudi- 
nally striated. Sterna and abdomen shining, finely punctured. 
The two smaller examples have the thorax relatively narrower 
than in the larger examples, and the rugulose surface more marked 
and more extended. These differences are no doubt sexual. 
These were found under stones and bark in the woods of the 
Sapate. 
Copidita, sp. 
Several examples of a species which I am unable to determine. 
Yellowish, usually with slight grey shade on the elytra. Length 
6-7 mi Him. 
Those captured were attracted by a light. 
Bruchida. 
Br,uchus porosus, Sharp. 
Two imperfect male specimens, which may be referable to B. 
porosus , Sharp (Biol. Cent.-Amer., Coleopt. v. p. 490), from Ghiate- 
mala, the type of which (unique) is a female. The brown colour 
is rather more suffused over the elytra, and the punctures are not 
quite so large. The pectinations of the antennae are very long. 
Ehynchophora. 
SlTOPHILUS ORYZA3, L. 
Introduced. [It is very destructive to the maize-grains, so that 
in the store-rooms the maize is covered with a thick layer of sand 
to prevent their attacks. — H. N. -ZL] 
Xylophaga. 
Tomicus ? 
Two immature specimens belonging to this or an allied genus. 
Very pale yellow ; lg millim. in length. 
Pycnarthruh ? setulosum, n. sp. 
Qblongo-ovatum, brunneum, sat nitidum, convexum ; thorace 
latitudine paulo breviore, convexo, postice paulo angustiore, ante
