Last of Colydiidee collected in the Indian Islands. 121 
In illustration of this new genus, I have thought it would be 
interesting to add figures of three of the allied genera above com- 
mented upon, of which no satisfactory representations have hitherto 
appeared. Figures of Torneutes and Hrichsonia will be found in the 
‘Transactions of the Entomological Society’ above referred to; of 
Thaumasus, in the French ‘ Annales;’ of Hypocephalus, in my 
‘Arcana Entomologica,’—Scaphinus and Mysteria being still un- 
represented.

XII.— List of the Colydiidee collected in the Indian Islands by Alfred 
R. Wallace, Esq., and Descriptions of new Species. By Francis P. 
Pascon, F.L.S., &e. 
Wiru the exception of a few species described by me in the previous 
Numbers of this work, the whole of the Colydians collected by Mr. 
Wallace, and enumerated in this paper, are entirely new to science. 
They are fifty in number, belonging to twenty-four genera, of which 
eight are now for the first time characterized. Of the older genera, 
Bothrideres is universal, and Cerylon scarcely less so, except that it 
has not yet been detected in Australia; besides these, the only genus 
represented in Europe is Colobicus. Of the Asiatic, or rather of the 
Indian genera (for we scarcely know anything of this family beyond 
the two peninsulas), we find exponents of six in this collection, viz. 
Phormesa, Machlotes, Dastarcus, Petalophora, Gempylodes, and Tra- 
chypholis, while the only known Indian genus not found in it is
