ZOOLOGY. $1 
(2) their larval forms, and (3) their habits. An account of his journey was published 
in the ‘ Entomological News’ for July 1910, pp. 334-337, and this has been followed 
by other papers on the results of his researches, the most important being the 
discovery of Odonate larve found living in the water which collects between the bases 
of the leaves of Bromeliads growing upon trees, and of the rearing of the imagines of 
Mecistogaster modestus from these larve. 
The ten plates belonging to this Volume, of which three are coloured, include 
figures of 178 species, all but nine appertaining to the Odonata. 
[No contributor has been found for the remaining families belonging to the 
Neuropterous-series in the wide sense, viz. Trichoptera, Neuroptera Planipennia, 
Mallophaga, Psocidze, Termitide, Embiide, and Perlide. | 
51. Ortuoprera. Vol. 1.: Forficulide by Count de Bormans; Blattide, Mantide, 
Gryllide, and Locustide by Dr. Henri de Saussure, assisted by Dr. Leo 
Zehntner and A. Pictet. 
Five families of Orthoptera are dealt with in this Volume: the Forficulide by 
de Bormans (published in 1893), and the Blattide, Mantide, Gryllide, and Locustide 
by de Saussure (published in 1895-1899). The Introduction, including the systematic 
list of species figured, was issued in 1900, when Vol. IL. of this subject was com- 
menced. De Saussure, in his enumeration, also considered it necessary to describe, 
notice, or figure various allied South-American or Antillean forms. | Under the 
heading to each family, tribe, &c., he deals with the general classification of the 
Neotropical fauna, and gives synopses of the genera, and under the genera them 
selves dichotomous keys to the species. The total number of species recognized as 
belonging to Central America is 633, of which 224 are new: Forficulide 41 
(8 new), Blattide 156 (60 new), Mantidze 61 (33 new), Gryllide 102 (43 new), 
Locustide 273 (80 new). The twenty-two plates, of which, iii., vi., vil., and viii., 
are coloured, include figures of 310 species. 
52. OrtHoprerRa. Vol. II.: Acridiide by Prof. Lawrence Bruner (the subfamily 
Tettigine by A. P. Morse); Phasmidee by R. Shelford. 
This Volume includes the enumeration of the two remaining families of the 
Orthoptera. The Phasmide should have been placed between the Blattide and 
Mantide, in Vol. I., but the account of them had to be deferred until the appearance 
of Brunner vy. Wattenwyl’s and J. Redtenbacher’s Monograph, the concluding portion 
of which was not published till 1908. Prof. L. Bruner’s work on the Acridiide, in 
which Mr. A. P. Morse assisted him with the subfamily Tettigine, was issued in 
1900-1908, the Tettiginee having appeared in 1900-1901. ‘The list of the Phasmide, 
published in 1908, was compiled from the above mentioned Monograph, the authors
