EAELY REMINISCENCES 
eupliorbiae were abundant in some places; on the snow-clad (in April) lava streams 
of the Pico del Teyde Mr. Wainwright took a specimen of Colias edusa at a height 
of nearly 10,000 ft. 
I have seen Sphinx convolvuli several times in my garden at Mortehoe; it would 
not look at Verbenas or Petunias, but showed a great partiality to the more 
gorgeous flowers of Gladiolus. I can confirm all that Mr. Barrett says about its 
noble flight, and the ease with which it may be observed. [By standing perfectly 
still, the insects will visit flowers quite close to one, even sipping honey from a spray 
of White Tobacco held in the hand—nay, more, on one occasion a moth so employed 
was rudely thrust aside by a yet bolder individual!]
