198 Mr. P. H. Gosse on the Insects of Jamaica. 
an elevation of (perhaps) 1500 feet, I found in March several 
groups of this Gyrinus. Their manners were much like those 
of G. natator, but they were less rapid in their evolutions, and 
when diving did not show any little pearl of air at the extremity 
of the body. They huddled together more : at one dash of a 
small ring-net I took forty-five. I subsequently saw the same 
species at other seasons of the year in the same brook. 
5. Dineutes metallicus. In a brook between Paradise and 
Savanna le mar in April. 
6. Creophilus villosus. On two occasions I have observed this 
beetle crawling and flying about animal substances in a state of 
putrefaction. It has an extensive range, for in Newfoundland it 
is so abundant about the drying cod-fish as to be quite a pest ; 
and I have found it also in Canada and in Alabama, U.S. 
7. Philonthus (sp. nov.). On the Hampstead Road is a grove 
of rose-apple trees [Eugenia jambos) ; when this fruit is ripe the 
stone is loose, not nearly filling the cavity that incloses it. In 
the decaying rose-apples beneath the trees I found this little 
beetle common, together with a minute Nitidula ; two or three 
being in the cavity of almost every decayed fruit. I do not ap- 
prehend that they are able to get into the cavity until a part of 
the pulp is destroyed by decomposition, but contact with the 
earth soon effects this. In no case were they in a sound fruit, 
though several in such condition lay beneath the trees. The 
season was the latter part of June. 
8. Belonuchus (sp. nov.). 
9. Osorius (sp. nov.). At the summit of Bluefields Peak in 
IMarch, I found this beetle in some numbers beneath the rotting 
bark of a fallen tree. 
10. Osorius (sp. nov.). Considerably less than the preceding : 
beneath a stone, on Bluefields Mountain, March I2th. 
11. Pcederus connatus (Haliday). A curious little species, ap- 
parently destitute of both wings and elytra ; the latter are how- 
ever discernible by the aid of a microscope, but soldered together. 
12. Phanceus (sp. nov.). Common on the roads, rolling pel- 
lets of horse-dung : it chiefly occurs in the lowlands. 
13. Onthophagus (sp.). Bluefields, in December. 
14. Trox (a sp. near murinus). 
15. 'Oryctes Jamaicensis. Three or four specimens of this spe- 
cies w^ere brought to me at different times ; all found near Blue- 
fields, and (as I believe) in the earth of cultivated grounds. 
16. Megasoma tit anus. Repeatedly brought to me, but I 
never found it alive. I have taken, however, the great horned 
males from the stomach of Nyctibius Jamaicensis, whence I infer 
that it flies by night. 
17. Cyclocephala signata. Very abundant at almost all times ;
