78 CONTENTS OF EACH VOLUME. 
author died in 1899. No other contributor could be found to undertake the groups 
Agromyzine, Borborine, Chloropsine, Drosophiline, Ephydrine, Geomyzine, and 
Sapromyzine, of the Muscide Acalyptere, and the Phoride, and the volume was 
closed as it stood. Pages 429-489, containing the Hippoboscide and the Supple- 
ment to the other families, were published after v. der Wulp’s death, although 
the new species of Muscide Calyptre had already been described by him in the 
‘Tijdschrift voor Entomologie’ for 1892. Altogether, 1095 species were named by the 
author, of which 585 were treated as new, the publication of his work extending from 
1888-1900, but the Titlepage and Introduction were not issued till 1903. 
The thirteen coloured plates include figures of 287 species. Some of the Trypetine 
are figured on the plates, others (11) in the text. 
45, Dirrera. Vol. III.: by S. W. Williston: Syrphide, Conopide, Pipunculide, and 
Platypezide. 
Prof, Williston’s contribution to this Volume, pp. 1-89, was published in 189i- 
1892, and the list of subsequently described species, and the general index to the 
whole of the three volumes, pp. 93-127, in 1903. The material again was scanty in 
comparison with the large number of species which must exist in the region, but 
among the Syrphids the genera Baccha, Volucella, and Eristalis were particularly 
well represented. The total number of species enumerated is 320, of which 67 
are new. The two coloured plates include figures of 29 species. 
46. Ruyncnota Hereroprersa. Vol. I.: by W. L. Distant: Pentatomide, Coreide, 
Lygeide, Pyrrhocoride, and Capside. 
Mr. Distant’s enumeration of the above mentioned families of Rhynchota Hetero- 
ptera (pp. 1-303) was issued in 1880-1884, the Supplement to the same (pp. 304-351) 
in 1889-1893, and the Appendix (pp. 452-462) in 1893, the delay in publishing 
the Supplement being due to his long absence in South Africa, Altogether, 
1108 species are recognized, more than half of which are described as new. In the 
Introduction, published in 1893, the number of genera belonging to each family is 
given and the geographical distribution shown in short Tables. Amongst the 
Lygwide nearly half the genera are stated to be endemic. The Pentatomide include 
377 species and are, therefore, very well represented in Central America, though 
many of the genera are common to the Neotropical region. The Capside, too, with 
313 species, are very numerous, but the tropical representatives of this family are 
but little known as yet, and no comparison with the fauna of the adjacent portion 
of South America can be made. The thirty-nine coloured plates include figures of 
upwards of 900 species, a complete list of them being given in the Introduction, 
pp. Xi-Xx.
