THE NEOTROPICAL REGION.

and Trigonopeltastes (6 sp.), allied to tlie European Triehius. The 
non-peculiar genera are, Stethodesrna, of which half the species 
are African and half tropical American ; and Euphoria, confined 
to. America both North and South. 
Buprestidse. — In this fine group the Neotropical region is 
tolerably rich, haying 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, Dicerca is mainly 
Nearctic and Pahearctic ; Cinyra has a species in North America 
and one in Australia; Curis is divided between Chili and 
Australia ; the Australian genus Stigmodera 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 ; Ptosima has one species in south tempe- 
rate America, the rest widely scattered from North America to 
the Philippines ; Adenodes has a single species in North Ame- 
rica and another in West Africa; Colobogaster has two 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 Prionidee 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, Pamndra and Mallodon, which are widely 
distributed ; and Er gates, found also in California and Europe. 
The most remarkable genera are, the magnificently-coloured 
Psalidognathm and Pyrodes ; the large and strangely marked
