1896.] ENTOMOLOGICAL NEV/S. 261 



ODONATA. 



Those collected in Burmah by L. Fea, in Sumatra and other 

 islands above mentioned by Dr. E. Modigliani, in New Guinea 

 by O. Beccari and L. M. d'Albertis, and by the Italian expedi- 

 tion to Equatorial Africa, all described by Baron E. de Selys- 

 Longchamps. 



Species from Erythraea by V. Ragazzi. 



The arranged collection of Coleoptera is contained in glass- 

 topped drawers 28 x 37 centimetres, that of Lepidoptera and of 

 Odonata in drawers 38 x 49 centimetres. The species are dis- 

 posed in horizontal series with numerous specimens from many 

 localities. Each specimen has a small pin-label bearing the 

 names of the locality and collector and the date of capture. The 

 types are distinguished by a pin-label. Labels for generic names 

 are of different color from the others. Labels for specific names 

 are white with a border variously colored according to the various 

 parts of the world, and there is a special color for the Italian 

 fauna. 



Each specific label [on the bottom of the drawer] has a number 

 which corresponds to a catalogue-slip on which are enumerated 

 the specimens of each species with their respective localities and 

 any other observations. 



To these notes of Dr. Gestro may be added a few additional 

 particulars from memoranda made by the writer at the time of 

 his visit. In those parts of the collection which have been most 

 recently arranged the specific labels of type specimens are written 

 in red ink to more readily distinguish them. Labels for generic 

 names have a black line-border, while the colors of the line-bor- 

 ders on the labels for specific names are green for North and 

 South America, blue for Africa, yellow for Europe, red for Italy, 

 violet for Australia and orange for Asia. 



The Museo Civico di Storia Naturale di Genova is of compar- 

 atively recent origin and the building which it occupies is yet 

 small, but it is the very modernity of this Museum, like that of 

 the Mus^e d'Histoire Naturelle at Brussels,* which has made it 

 possible to so carefully mark and catalogue each individual speci- 

 men, a task which the absence of data often renders impossible, 

 or of doubtful value, in many of the older European entomo- 

 logical collections.
