122 Mr. F. P. Pascoe on the Colydiide 
Tarphiosoma. If we except Bothrideres, Penthelispa, and Phormesa 
(the two former almost universally distributed), we have no genus 
common to the Indian islands and to Australia. This is the more 
remarkable, as we are now acquainted with eleven genera from that 
division of the world, all very distinct, and some of them rich in 
species. It is perhaps still more remarkable that four of the Indian 
genera, viz. Distaphyla, Minthea, Nematidium, and Ocholissa, have 
representatives in Tropical America, and nowhere else. 
With regard to the distribution of the Colydiide in the Indian 
Islands there is nothing, so far as this collection is concerned, to call 
for any particular remark. Nine genera were found in New Guinea, 
three of which only are peculiar, viz. Bupala, Caprodes, and Eba. 
Few of the species appear to have been met with in more than one 
island. The exceptions were Ocholissa humeralis, which was found 
at Saylee (New Guinea), in Morty, Mysol, and Batchian ; Dastarcus 
confinis at Dorey, Macassar, and Aru; Chorites oblongus at Macassar, 
Ceram, and Batchian; Minthea simillima at Saylee, Ceram, and 
Macassar; Hyberis araneiformis at Sarawak and Singapore; Phor- 
mesa heros at Dorey and Morty; Nematidium posticum at Sarawak 
and Amboyna; and Dastarcus vetustus at Ceram and Batchian. The 
little island of Mysol furnished eight species, only one of them, 
Ocholissa humeralis, having being detected elsewhere. It must be 
observed, however, that Mr. Wallace did not trouble himself with 
these ‘‘ small game,’’ except when he had nothing else to do; conse- 
quently many of the islands, such as Bouru, Gilolo, Aru, Key, 
Waigiou, and others, are not represented at all, or only by a single 
specimen. In the following table I have adhered to the five sub- 
families into which Erichson has divided this family :—
