160 THE ENTOMOLOGIST. 



The systematic arrangement of the family is pretty much that of 

 Mabille ('Genera Insectorum,' 1903). 



So far as is known, ninety-five species of Hesperidae are found in 

 Java, but upwards of twenty others have been recorded from the 

 island. The latter, however, are considered doubtful, for as we are 

 informed in the Introduction — " not a few butterflies in European 

 collections are said to originate from Java, though in reality they are 

 not from that island, but have been gathered from other islands in 

 the Indian Archipelago and only transported via Java to Europe." 



Roth sexes are shown in thirty of the seventy-eight species 

 figured, and one or more of the early stages of a good proportion are 

 also depicted in colour. Of eleven other species, the imagines of 

 which are not drawn, there is a figure of the larva of each, and in the 

 case of two of them, the pupa also is shown. 



Where known the larvae are described, and their habits and food- 

 plants noted. The distribution of the species in Java is also indi- 

 cated. No new species is here described, but several of Moore's 

 species that had been degraded by previous authors have been rein- 

 stated. The only local form that is specially mentioned is referred to 

 as follows : — " Among the specimens of the type Acerbas antJiea 

 described by Hewitson and figured by Distant according to a male 

 from Malacca, the white band does not continue up to the external 

 margin as it does with the Javanese specimens, for which reason the 

 latter can be distinguished as forma Javanica."

One hundred and seventy species of Danish Empididae are 

 here described and assigned to five subfamilies in the following 

 sequence : — 1. Hybotinae (3 genera, 9 species). 2. Empidinas (3 genera, 

 78 species). 3. Ocydromiinae (6 genera, 13 species). 4. Hemero- 

 dromiinaB (7 genera, 18 species). 5. Tachydromiinae (8 genera, 52 

 species). A few other doubtful species are incidentally referred to. 

 Bicellaria, Macq. supersedes Gyrtoma, Meig. for nigra, Meig., spiuria, 

 Fall., melana, Hal., &c. Geniculata, Zett. is referred, as a variety, 

 to Bhamphomyia plwnipes, Fall. Ocydromia ruficollis, Meig. is the 

 female of Leptopeza flavipes, Meig., whilst ruficollis Macq. is referred 

 to Ocydromia glahricula, Fall. Dolichocephala, Macq. is adopted for 

 irrorata, Fall., and guttata, Hal. ; melanocephala, Fabr. is referred to 

 Chelipoda, Macq. ; and vocatoria. Fall, with alhiseta, Zett. come under 

 Phyllodrornia Zett. ; dissimilis, Fall, is removed from Tachydromia, 

 Meig. to Symhallophthalmus, Beck. Our author is of opinion that 

 nervosa, Loew is specifically identical with Drapetis aterrima, Curtis. 

 The twenty-nine species of Empiis, L. are arranged in seven groups 

 or subgenera, thus: — Xanthempis, Bezzi (6 sp.), Anacrostichus, 

 Bezzi (1 sp.), Pachymeria, Stephens (1 sp.), Lissempis, Bezzi (1 sp.), 

 Coptophlehia, Bezzi (3 sp.), Pterempis, Bezzi (11 sp.), Empis, S. Str. 

 (6 sp.). 



Part i. of ' Diptera Danica ' was published in 1907, and Part ii. 

 in 1908.
