is finely longitudinally rugulose, but this is very sHgbt in tlie 

 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 difierences 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 wdth slight grey shade on the elytra. Length 

 6-7 millim. 



Those captured were attracted by a light. 



Bruohida. 



Bbuchus poeosus, Sharp. 



Two imperfect male specimens, which may be referable to B. 

 porosus, Sharp (Biol. Cent.-Amer., Coleopt. v. p. 490), from Guate- 

 mala, the tyxDO 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. 



Rhtnchophora. 



SlTOPHILUS OEYZ^, 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. iV. jB.] 



Xtlopha&a. 

 ToMicus ? 



Two immature specimens belonging to this or an allied genus. 

 Very pale yellow ; l^ millim. in length. 



PyONAETHEUM ? SETULOSUM, U. Sp. 



Oblongo-ovatum, bruuueum, sat nitidum, convexum ; thorace 

 latitudine paulo breviore, convexo, postice paulo angustiore, ante
