to be seen there ; there are also pepper trees, eucalyptus, fir, and poplar. 

 In the gardens occasional very fine timber is to be seen ; coffee trees, orange, 

 lemon, magnolia, tallow, bread fruit, etc., abound. I must not forget to 

 mention the famous dragon tree, indigenous to these islands. As 

 regards wild birds, we noticed green canaries in great numbers, black- 

 caps, hoopoes (Upupci epops), blackbirds, several species of vultures and 

 eagles, ravens, crows, and several very pretty small birds, which were 

 unknown to me. Lizards of all sizes, from a couple of inches to a foot 

 and a half in length, and of all colours, were extremely abundant, and 

 very beautiful some of them were. Altogether the Canaries are a 

 delightful place to spend a holiday in; they are easy of access, and I 

 can heartily recommend them to brother entomologists. 



Amongst the insects captured may be mentioned the following : — 



Danais archippus. Deilephila celerio. 



Satyrus acgeria. D. livornica. 



Satyrus janira. Plusia — 



Vanessa cafdui, - Plusia — 



Syrichtus — • Plusia — ■

THE SEXUAL DISTINCTION OF INSECTS.

I.— Di sparity of Colour — {continued, from page, 164). 



In Coleoptera, colour does not play an important part between the 

 sexes. The nearest approach to complete unlikeness is apparently 

 presented by Osphya bipunctata, in which the male is black, with the 

 edge of the thorax, the base of the antennae, and the legs (mostly) 

 reddish ; while the female is yellowish brown, with the top of the head, 

 two spots on the thorax, and the tip of the elytra black. The male of 

 the Metcecus paradoxus has the elytra almost entirely yellow, while in 

 the female they are nearly or quite black. The male of Campylus 

 linearis has the elytra pale yellow, with or without a dark suture ; the 

 female has them black, with a yellow outer border. Tillus elongatus 

 and Cryptocephalus coryli have the thorax black in the male, bright
