very unlikely to have occurred on the same lines. Dr. Sharp did not 

 tell us how the external wing-buds became internal, nor do we know 

 of any transitional form, but precisely the same phenomenon of external 

 organs becoming internal (imaginal discs) may be seen within the limits 

 of one order, as in the Hymenoptera, where Tenthredo has legs in 

 the larval stage, and most of the other families have not. We have, 

 indeed, the same phenomenon occurring in the life of a single indi- 

 vidual, in the Coleoptera of Meloid affinities, MeliJc, Sitaris, lihip- 

 iphonis, Cantharis, Stylops, etc., and the question could no doubt be 

 investigated here by modern methods with some facility.

Notes on the British Longicornes.

 [Cant imied from p. 223.) 



There are three British species of Clytus, the first, Clytiis arcnatus, 

 L.,beiugvery rare. Some of the captures have undoubtedly been importa- 

 tions, those from AYest Greenwich being from a shoe-last factory. Dr. 

 Power, however, took it in Eppiug Forest, and so did Mr. Waterhouse 

 and hie brother, out of an old cherry-tree. The wild cherry may be its 

 pro]3er pabulum, and thus account for its rarity. It is a large glossy 

 black insect, with yellow spots and bauds. Clytns arietis, L., the 

 commonest species of the other three, somewhat resembles the last insect, 

 l)ut is neither so large nor robust, and the yellow bands are differently 

 arranged. It occurs in old posts and rails, and may also be taken by 

 beating blossoms and sweeping flowers. It is generally distributed 

 from the Midlands southwards, rarer further north. I have seen it in 

 numbers running on fresh felled trees, from which the bark has been 

 removed, in the New Forest, and have taken it in Leicestershire, and at 

 Chiddingfold, etc. Clytus mysticus, L., is very difiFerently coloured from 

 the last two species, being of a black hue marked with chestnut, 

 red and grey ; it is widely distributed, but decidedly local. It is to be 

 taken by beating hawthorn blossoms. I have taken it in the New 

 Forest, at Darenth Wood, in Huntingdonshire, and in Richmond Park, 

 in March, out of a hawthorn bough. It has been taken in Leicester- 

 shire by Mr. Woolley. The next little species, Gracilia mimita, F. 

 (pygmaea, F.), is called the "Basket Beetle," being generally found 

 in old baskets and hampers. It is a small brown inconspicuous insect. 

 I have taken it by sweeping in a meadow at Kingstone, and in numbers 

 by beating an old basket at Hastings (out of which, by the way, I also 

 got a series of a small foreign Longicorne, Le^Mdea hrevipennis, 

 which has short elytra ; it has been taken several times before in 

 England). It occm's in Leicestershire. I have a specimen I took in 

 Leicester in 1882. Obrivm cantharinnm, L., is a very rare, gTaceful, 

 yellowish insect. It has only been taken by Dr. Power since Stephens' 

 time. The doctor bred it in some numbers from aspen bark from 

 Wanstead. It also occurs in apple-trees. 



The next genus, Molorchns, has the elytra strongly abbreviated, with 

 the true wings exposed. We possess two species, of which Molorchns 

 minor, L., is the larger, It used to be considered the rarer, but I
