 prium, qui nee apothecium discocarpum nee pyrenocarpum 

 sistit ; ab illo scilicet differt perithecio supra continuato totum- 

 que hymenium involvente ; ab hoc (pyrenio) differt ostiolo 

 non regulari contractoque nee anaphysibus intus munito, sed 

 rimula vel varie dehiscente. Adest hie peridium , fere sicut in 

 Fungis variis. Distinguenda est duobus generibus allatis,

 Peeceval Wright, M.D., F.L.S., Professor of Botany and 

 Zoology in Trinity College, Dublin. With a List of the 

 Species and Descriptions of a new Genus and some new Spe- 

 cies ; by the Baron E. de Selts-Longchamps. 



During my six months' residence at the Seychelles I was 

 very much struck by the apparent absence of insect-life. 

 Ants and musquitoes, indeed, abounded : the former were busy 

 everywhere, and nothing that could be carried off was left 

 very long alone by them ; the latter were a constant source of

 big moths to flap over and extinguish them. This was espe- 

 cially the case during the months from June to September. 

 Towards October insects began to appear, the Cicadas were 

 heard in the trees, and I have little doubt that if I had stayed 

 at the islands for the whole of the rainy season I should 

 have collected or seen a fair proportion of species. A large
