PHASMTM. 343 



Fam. PHASMIDJE*. 



It is more than ten years ago that the Godman-Salvin collection of Phasmidse was 

 entrusted to Hofrath C. Brunner von Wattenwyl for determination and study. The 

 famous Austrian entomologist would not undertake to publish a separate memoir on 

 the collection, but preferred to incorporate the descriptions of the new species and 

 genera in the great monograph on the Phasmidse of the world, ' Die Insektenfamilie 

 der Phasmiden,' which, in collaboration with Dr. Jos. Redtenbacher, he has just 

 completed. Consequently it has not been possible to prepare an account of the 

 collection until the present year, or to include the family in its proper place in 

 the Orthoptera. The following pages contain a list of the Phasmidee of Central 

 America compiled from the aforesaid monograph, and it will be seen that there are 

 numerous species not represented in the Godman-Salvin collection. The dichotomous 

 keys to the subfamilies, genera, and species are reproduced with the necessary modifi- 

 cations from the corresponding keys in ' Die Insektenfamilie der Phasmiden,' as it 

 was thought that they would prove useful to any one studying the Central-American 

 fauna, but for the descriptions of the genera and species students are referred to the 

 original sources and to the monograph. The plates illustrating this collection were 

 prepared some years ago in Vienna under the supervision of Hofrath C. Brunner von 

 Wattenwyl, and as his views of the nomenclature of the Phasmidae had at that time not 

 reached the finality now attained in his monograph, the names of the species given on 

 the plates in some cases differ from those used in the monograph. (See " Explanation 

 of Plates," infra, p. 377.) Several South-American or Antillean forms have been 

 figured, presumably because Hofrath C. Brunner von Wattenwyl holds elastic views 

 as to the limitations of the Central-American region, and no doubt some of these 

 species will eventually be found to occur also within the "■ Biologia " limits ; in the 

 text they are quoted, as elsewhere in this work, in square brackets.
