GHAP. XIV.] THE NEOTROPICAL REGION. 17 



and Trigonopeltastes (6 sp.), allied to the European Trichius. The 

 non-peculiar genera are, Stetlwdcsma, of which half the species 

 are African and half tropical American ; and Eiiphoria, confined 

 to America both North and South. 



Buprestidse. — In this fine group the Neotropical region is 

 tolerably rich, having examples of 39 genera, 18 of which are 

 peculiar to it. Of these, the most extensive are Conognatha and 

 Halecia, which have a wide range over most parts of the region ; 

 and Dadylozodes, confined to the south temperate zone. Of im- 

 portant genera which range beyond the region, Diccrca is mainly 

 Nearctic and Paltearctic ; Cinyra has a species in North America 

 and one in Australia ; Curis is divided between Chili and 

 Australia ; the Australian genus Siigmodera has a species in Chili ; 

 Polycesta has a species in Madagascar, two in the Mediterranean 

 region, and a few in North America ; Acherusia is divided between 

 Australia and Brazil ; Ftosima has one species in south tempe- 

 rate America, the rest widely scattered from North America to 

 the Philippines ; Actenodes has a single species in North Ame- 

 rica and another in West Africa ; Colohogaster has tAvo in West 

 Africa, one in Java and one in the Moluccas. The relations of 

 South America and Australia as indicated by these insects has 

 already been sufficiently noticed under the latter region. 



Longicornia. — The Neotropical Longicorn Coleoptera are over- 

 whelming in their numbers and variety, their singularity and 

 their beauty. In the recent Catalogue of Gemminger and 

 Harold, it is credited with 516 genera, 489 of which are peculiar 

 to it ; while it has only 5 genera in common (exclusively) with 

 the Nearctic, and 4 (in the same way) with the Australian region. 

 Only the more important genera can be here referred to, under 

 the three great families into which these insects are divided. 



The Prionidae are excessively numerous, being grouped in 64 

 genera, more than double the number possessed by any other 

 region ; and 61 of these are peculiar. The three, common to 

 other regions, are, Parandra and Mallodon, which are widely 

 distributed ; and Ergates, found also in California and Europe. 

 The most remarkable genera are, the magnificently-coloured 

 Psalidognathus and Pyrodes ; the large and strangely marked
