Attacus pernyi.-The eggs obtained of this hardy species hatched and fed up well, and a fine group of larvae were exhibited throughout the month; there are now about 40 full-sized cocoons in the case, which will produce imagos during August for second brood. This species thriving well upon evergreen oak, can be fed far into the autumn. No. 5. Attacus atlas.-Imagos of this species were exhibited alive in the case throughout the month. A fine group of 11 perfect insects emerged on Sunday, 24th instant. This is an extremely difficult species to induce to copulate. I have tried honey sponge and other methods unavailingly, so that only about 10 per cent. of the imagos have copulated, which, however, have given a nice lot of eggs. The first brood of larva? died after first moulting. The second brood, hatched June 20, have done very well, and have been exclusively fed upon a shrub (evergreen) common in the gardens; so that this, like the preceding species, can be fed into the late autumn. No. 6. Attacus mylitta.-Fine imagos of this species appeared on the 3rd, 10th, 12th, 20th, and 24th, unfortunately at too wide intervals to obtain eggs. There appear to be ten more cocoons still likely to emerge. [The insect bred on the 3rd unfortunately escaped, flying with great rapidity out of the cage when it was opened, and through the narrow window at the end out into the open. A good search was made; hut it was not found. Some very fine specimens of unusually bright colour have been preserved.] No. 7. Actios selene.-Perfect specimens appeared on the 7th, 10th, and 23rd instant, and, being in very fine condition, were preserved. Unless the sexes emerge same day, there is little likelihood of procuring fertile eggs ; and the species will not retain its beauty after one night; invariably on the following morning the insect is in a very battered condition. No. 8. Actios luna.-One specimen of this species emerged on the 6th instant; there appear to be others yet likely to come out. No. 9. Telea promethea.-Small larvae of this species have been exhibited from eggs obtained in June; but the little brood of 17 larvae died on the 10th instaut. I hope for more later on. No. 10. Antheraa yama-mai.-A fine female of this species emerged on the 22nd instant from eggs hatched April 16th, being 3 months and 6 days reaching maturity. I expect others to emerge, and so to get second brood. No. 11. Hybrids between Attacus pernyi and Attacus roylei.- Five larvae, reputed to be these, were kindly deposited by Lord Walsingham on the 4th instant. One died the following day ; three have formed cocoons; and the fifth is still feeding, but growing very slowly, if at all. I have been unable to detect any difference between these larvae and those of Attacus pernyi. No. 12. Aglia tau.-Five fine larvae of this species were deposited |
