would fall in Chaudoir’s group III. No additional material 
has been secured from the Lesser Antilles, where there are 
still 3 species recorded which are unknown to me, so the 
following key has been constructed to cover only the species 
of the Greater Antilles. In this region there is now only 
one described species which I do not know, C. ( Metalloso - 
mus) cuprascens Mots. (Bull. Soc. Nat. Moscou 37, 1864, 
no. 4, p. 305), described from “St. Domingue aux Antilles.” 
The description is superficial, but the species is evidently 
very different from any I have seen. 
With the exception of the widely ranging C. sequinoctialis 
Chd., I know of no Colpodes which occurs either on the 
Greater Antilles and the mainland (I have seen at least half 
the known Central American species), the Greater and 
Lesser Antilles, any two of the greater islands, or even upon 
any two separate mountain ranges on a single island. 
They are evidently so local that I feel safe in describing 
West Indian species without discussing their relationship 
individually with the continental fauna. 
Key to Greater Antillean Colpodes ( excepting cuprascens 
Mots.) 
1. Tibiae finely sulcate along extreme outer edge; tarsi 
strongly trisulcate above 27. 
Tibiae not sulcate on outer edge; tarsi with not more 
than 2 sulci above 2. 
2. One or more supra-ocular and/or lateral thoracic setae 
missing; Jamaican species 3. 
Two supra-orbital and 2 lateral thoracic setae each side ; 
species not on Jamaica, except for the widely dis- 
tributed xquinoctialis 8. 
3. Two supra-ocular setae each side 4. 
One supra-ocular seta (the anterior) missing 5. 
4. Anterior lateral thoracic seta present, posterior miss- 
ing ; elytra much duller than head and prothorax . . . 
cinchonas Dari. 
Anterior seta missing, posterior present; elytra not 
duller than head and prothorax; (metepisterna much 
more elongate) 22.
