STUDIES IN MALAYAN, PAPUAN, AND AUSTRALIAN MANTIDiE. 



BY MORGAN HEBARD. 



During the past thirteen years the author has received by pur- 

 chase from dealers in London, Paris and Berlin, several collections 

 and numerous individual specimens of Orthoptera from the South 

 Seas and adjacent continental areas. Recently a large number of 

 species of Mantidse, assembled by Mr. C. F. Baker in the Malay 

 Peninsula, Borneo and the Philippines, have been received. 



It was noted, upon assembling all of the Mantidse represented, 

 that a sufficient series was availaljle to justify the undertaking of 

 a study of the material of that family before us from the regions 

 referred to above. Seventy-eight species, representing forty-one gen- 

 era, are here treated, of which five genera and twelve species are 

 described as new. The collections contain a very good representa- 

 tion, including many of the most remarkable and little known forms. 

 Though in some of the groups only a minimum of the known species 

 are before us, we feel that, on the whole, the collection is one of the 

 most complete, for the Malayan region in particular, now extant 

 in any of the world's museums. 



This is in large part due to the efforts of Mr. C. F. Baker, and 

 when we consider that he is forming collections in all orders of in- 

 sects, we feel that he should be heartily congratulated on his achieve- 

 ments to date. It is our sincere hope that his work may continue 

 successful and uninterrupted for many years to come. 



All of the material treated in the present paper, unless otherwise 

 assigned, is in the Hebard Collection at the Academy of Natural 

 Sciences of Philadelphia, with the exception of duplicate specimens 

 from Mr. Baker, of species which are not represented in his collec- 

 tion; these will be forwarded to him whenever desired. 



We have included the species from the Malayan, Papuan and 

 Australian regions, as some of the forms of each of these inter- 

 digitate over extensive areas with those of the regions adjacent. 

 We would note, however, the vital importance of Wallace's Line, 

 separating the Malayan and Papuan faunas. The great majority 

 of species found in the Malay Peninsula, Sumatra, Java, Bali, 

 Borneo and the Philippines, have little in common with those of
