living specimens of a "leaf-insect" from the Seychelles, bred 

 in England by Mr. St. Quintin, probably Pulchriphyll'mm 

 crurifoUum, Serville. Mr. Meade- Waldo stated that these 

 insects were brought originally from the Seychelles by Lord 

 Crawford, and that those exhibited belonged to the second 

 genex'ation. 



Lampyrid^ prom Ceylon. — Mr. Gahan also exhibited some 

 Lampyridse, of considerable interest collected by Mr. E. E. 

 Green in Ceylon, and including both sexes of the genera 

 Lampriijera and Dioptoma, the females of which had hitherto 

 been unknown. The females of both genera were larviform ; 

 that of Lamjyrigera resembled in form the lai'va of the same 

 genus, but differed in the greater development of the antennae 

 and tarsi, the former being G to 7-jointed and the latter 

 3 or 4-3ointed ; the eyes were, however, simple as in the 

 larva. The female of Dioptoma had a general resemblance to 

 the female of Di-ilus flavescens, but was furnished with a very 

 distinct photogenic organ, as evidenced by the large, bright 

 yellow sternal plate of the seventh abdominal segment ; the 

 eyes were facetted, emarginate behind as in the male but 

 much smaller in size; the antennte were 12-jointed and the 

 tarsi 5-jointed. He showed also a larviform insect, probably 

 an adult female, which he had found to be full of eggs. This 

 insect was of the same genei'ul type as those remarkable 

 trilobitiform insects, described by Perty, Westwood and others, 

 and which had generally been regarded as the larvje of 

 Lycidx or Lampyridx. Like these it had large spiracles on 

 the methathorax. He called attention also to the existence in 

 China, Ceylon and the Malay Peninsula of remarkable 

 lax-viform females greatly resembling the females of the 

 American group Phengodhii, and being somewhat similarly 

 provided with rows of luminous points. The males of these 

 forms were not yet identified, but he suspected they would 

 prove to belong to genera at present i-eferred to the family 

 Dr'didx. 



Mr. K. Shelford remarked that in several of the Mala- 

 coderm Coleoptera from the Malay Archipelago regarded as 

 larval or apterous forms, the males and females were indis- 

 tinguishable, and underwent practically no metamorphosis.
