 These are a fair sample of the better known books, and the prices 

 quoted will strike those who know, as being remarkably irregular, and, 

 from the seller's point of view, unsatisfactory. One feels one would 

 like to know what some of the better books would have fetched with 

 spirited opposition, for to suppose that many reached a moiety of their 

 true market value is absurd.

Exotic Conocephalidae in Exglaxd. — From time to time, various 

 species of exotic Conoeejdialidae have been taken in this country, chiefly 

 in hothouses. In several cases the specimens have been kept alive, 

 and fed on flies and spiders. In 18G9, Butler noted at the Entomo- 

 logical Society of London, that a number of Cunocephalus joined a 

 ship oft' the west coast of Africa. They were green at the time, but 

 soon changed to brown. Many died on the voyage, but several actually 

 reached the Thames alive. These may very well have been captured 

 in the neighbourhood, and recorded as "locusts." At a meeting of 

 the Society in 1882, Mr. .Tenner "Weir exhibited some examples which 

 he considered to be Co)iocephali(s ensitjer, Harris, an American species. 

 He had received them from -J. Veitch and Sons, of Fulham Road, with a 

 note to the eft'ect that they were numerous in their hothouses. They 

 had been kept for some weeks in captivity, feeding readily on flies and 

 spiders. In the following year Mr. Billups recorded a Conocephalus (?) 

 that had been taken in a greenhouse at Lee. It had lived in captivity 

 for ten days on a diet of spiders, flies and meat. It seemed to prefer the 

 common housefly. Shortly afterwards a similar one was taken, which was 

 considered to be Cupiojdiora cornitta, de G. In 1885, Mr. McLachlan 

 exhibited, at a meeting of the Entomological Society, a speciuien of 

 Cojiioiilinra cornnta (?) taken in a hothouse at J>irmingham. INlr. Eland 

 Shaw mentioned that M. de Saussure had seen the specimens, without 

 recognising them, but that he considered them to have come from 

 Australia, though the captors thought that they had been iuiported 

 from America. The specimen recently recorded from Kew (iardens 

 by ]\Ir. Lucas was certainly an American species. The Conorejihalidae 

 are a large and widely-distributed family of Locuatodea, monographed 

 by Redtenbacher. Conorejdtalits )iiandibnlaris, Charp., occurs prac- 

 tically throughout the Old World, except Australia. It is quite 

 common in southern Europe, but does not occur so far north as 

 I'higland. Of this genus alone there are about seventy species known. 

 Another large genus Xijdiidiiim, Latr., is also widely distributed. 

 X.J'Ksciiin, Charp., is common in central and southern Europe, and is
