On some Species of Cetoniidse/lwra the Loo Choo Islands.
By Oliver E. J anson, F.E.S.
In the Ann. & Mag. Nat. Hist, for March 1887 Mr. GeorgeLewis has given a revision and list of the Cetoniidae of Japan ;but at that time very little was known of the insects of theLoo Choo Islands, and no species is recorded by Mr. Lewisfrom this locality. Recently my friend Mr. H. Pryer visitedthese islands and made a small collection, and judging bythe Coleoptera received from him it would appear that theinsect-fauna is very closely related to that of Japan . Threespecies of Cetoniidae have been sent to me by Mr. Pryer ; ofthese the two species of Cetonia are apparently undescribed,they bear a marked resemblance one to the other in colourand general aspect, but are not closely allied.
1. Glycyphana forticula, Jans.
Glycyphana forticula, Janson, Cist. Eat. ii. p. 608 (1881).
I described this species from a single specimen receivedfrom Japan without indication of the precise locality ; but itprobably came from the island of Kiuskiu. Mr. Pryer hassent a second specimen from the Loo Choo Islands whichdiffers from the type in its rather smaller size and in theabsence of the small white discal spots on the thorax andelytra and the four spots on the pygidium.
2. Cetonia Leioisi, n. sp.
Viridis, nitida, tibiis tarsisque seneis vel cupreis ; elytris posticesparsim albo-maculatis ; clypeo elongato, lateribus elevatis, apiceanguste reflexo, sinuato • thorace margine postico ante scutellumfortiter emarginato; scutello lato, apice rotundato; processumesosterni producto valde dilatato.
Long. 26-30 mm.
Var. elytris immaculatis.
Shining green, slightly golden,- tibiae and tarsi brassy orcoppery, elytra in some specimens with sparse white spotsbehind. Head rather coarsely punctured, slightly longitu-dinally convex, the clypeus elevated at the sides, the apexnarrowly reflexed and slightly emarginate. Thorax veryfinely and sparsely punctured on the disk, the sides morecoarsely punctured, slightly impressed on each side behind,
