conspicuously so upon the great slopes of the basin of Machachi, 

 where it was frequently met with, flying in large companies, in rather 

 open order.^ 



RHYNCHOTA. A small insect that has been referred to the genus 

 Emesa (p. 117) Avas the solitary example of its order which was taken 

 at a great elevation. This was obtained at 16,500 feet on the southern 

 side of Illiniza (about a thousand feet above the snowdine), and was 

 obviously a straggler. We saw no other living thing at so great a 

 height as this, and the only animal remains which were obtained at 

 an equal or greater altitude were the partly fossilized bones which 

 were found at 18,000 feet on the southern side of Chimborazo.^ 



The interior of Ecuador is rich in this order of insects, and the 

 small extent of our collection is due to the fact that we Avere unable 

 to give the necessary time for research in the most favoured localities. 



CRUSTACEA. It is observed in Chapter V. of Travels amongst the 

 Great Andes that Crustacea appear to be scarce in the interior of Ecua- 

 dor. Five species only were obtained,^ and these, although new to the 

 country, Avere all previously knoAvn. The three species of Woodlice 

 Avere both numerous and AA'idely distributed, and it is not easy to under- 

 stand hoAv they have been overlooked by others. One of these, namely 

 AletojJonortJms p'uinosus, is amongst the exceptional species with a great 

 range in altitude, having been taken Avith my own hands on the banks 

 of the Guayas at the level of the sea, at the Hacienda of Antisana 

 (13,300 feet) and at several intermediate points. The single Amphi- 

 pod, Hyalella inermis, S. I. Smith (p. 125), captured at the Hacienda of 

 Antisana, in the Valley of Collanes (12,500 feet), and near Machachi 

 (9800 feet), was numerous at each of those localities, and is probably 

 Avidely distributed in the interior. According to the Rev. T. R 11.
