VII. On some Phytophagous Coleoptera (Kumolpide) from 
the Islands of Mawritius and Réunion. By MARrtIn 
JACOBY, F.E.S. 
[Read February 2nd, 1898.] 
Monsieur Charles Alluaud of Paris, who spent some 
weeks in the Islands of Mauritius and Réunion, has 
kindly submitted to me the Phytophaga he obtained at 
these places. Some of the species appear to be new to 
science, and of these I here give the descriptions. But 
few species from these localities are known at present, and 
in some instances those which have been described have 
remained doubtful as to their proper genera, and are 
wrongly placed in Catalogues. 
Those dealt with in this paper all belong to the 
Eumolpide, and it is certainly remarkable that so many 
different species of one family should be found in such 
small and isolated localities, a fact which scarcely agrees 
with Wallace’s theories with regard to island faunas; the 
genus 7'richostola however is not confined to these islands 
but is represented in Africa. 
The insects described here were obtained at Carepipe in 
the centre of Mauritius at a height of about 1000 feet, 
and in the Plaine des Palmistes in the Réunion mountains 
at an elevation of 3000 feet. 
Trichostola (Acis) vestita, Boh. 
Among the Phytophagous Coleoptera described by 
Boheman in the “ Hugenies Resa” the present species is 
one of which the genus has been doubtful and was not 
known to Chapuis or Lefévre. The latter writer placed it 
in Colasposoma Cast., which is rather remarkable, since no 
form of such small size has ever been known of this genus, 
in species of which a dense pubescence is very uncommon. 
Curiously enough, Chapuis has described, or rather 
diagnosed, another Z'richostola from the same locality
