liviiji,' specimens of ii " k'ul'-iiisect " from ilie Seychelles, bred 

 ill England by Mr. .St. (Juintin, probably l\dchripJiijllmm 

 crurifolkmi, 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 

 generation. 



Lampyrid.e from Ceylon. — Mr. Gahan also exhibited some 

 Lampyridx of considerable inteiest collected by Mr. E. E. 

 Green in Ceylon, and including both sexes of the genera 

 Lamprifjera and Dioptoma, the females of which had hitherto 

 been unknown. The females of both genera were larviform ; 

 that of Laiajvicjera resembled in form the larva of the same 

 genus, but differed in tlie greater development of the.antennaj 

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

 3 or 4-jointed ; the eyes were, however, simple a« in the 

 larva. The female of Dioptoma had a general leseriibdance to 

 the female of Bo-ilus Jlavescens, but was furnished w'\\h a very 

 distinct photogenic organ, as evidenced by the larjFvp, bright 

 yellow sternal plate of the seventh abdominal segnrent ; the 

 eyes were facetted, emarginate behind as in the '#iale but 

 much smaller in size; the antennre were 12-jointedi and the 

 tarsi 5-jointed. He showed also a larviform insect ' '^n-obably 

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

 insect was of the same general type as those remarkable 

 trilobitiform insects, described by Perty, Westwood ard others, 

 and which had generally been regarded as the larvie of 

 Lycidx or Lampyridce. Like these it had large spiracles on 

 the methathorax. He called attention also to the existence in 

 China, Ceylon and the Malay Peninsula of r 'uarkable 

 larviform females greatly resembling the females of the 

 Americftn group J^hengodiui, and being somewhat similarly 

 provided with lows of luminous points. The males of these 

 forms were not yet identified, but he suspected they would 

 prove to belong to geneia at present referred to the family 

 Drilidie. 



Mr. R. SriELFORD remarked that in several of tv)ie Mala- 

 coderm Coleoptera from the Malay Archipelago regarded as 

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

 tinguishable, and underwent practically no jnetamorphosis.
