COLEOPTERA CARABIDAE OF THE JUAN FERNANDEZ ISLANDS 631 
process is glabrous, the metepisterna much longer than wide. The venter is 
glabrous, the ¢ without basal fovea, the apical segment with one marginal seta 
on each side in the ¢, two setae in the 9. The metafemora have two setae 
on the hind margin; the tarsi are glabrous above, the pro- and mesotarsi ¢ 
with four dilated joints, clothed beneath with rather large irregular whitish 
scales, joint 4 bilobed or deeply emarginate. In 7. fadllipes the microsculpture 
of the elytra consists of very wide meshes, while on the head and prothorax 
it is barely visible; the tooth of the mentum is sharp; tarsal joint 5 has on 
the underside a pair of small setae near apex. 
The genus appears to be related to the chinese Lzoho/us Tchitch., which 
is unknown to me in nature

The specimens agree fairly with the description, but the elytral striae, 
said to be impunctate, are actually very finely crenulate.

These three new species have all the main characters distinguishing the 
Pterostichini, that is to say the mesocoxal cavities are entirely closed by the 
sterna, the mandibular scrobe has no seta, the elytra have an inner plica and 
are not truncate at apex, the head has on each side two supraorbital setae, 
the labial palpi are bisetose, the tooth of the mentum is bifid, and the pro- 
sternal declivity rounded. All three species, however, present unusual characters, 
and none would be included under Pterostichus sens. str. in the palaearctic 
series. The Carabidae of South America are so imperfectly known at present 
that I hesitate to propose a new genus or new genera, and think it better to 
await a more intensive study of the fauna in future years.

This common species, which also appears in our catalogues under several 
other names, was originally described from the circum-mediterranean littoral. 
It has been carried by ships to nearly all parts of the world, and may now 
be regarded as almost cosmopolitan.
