STUDIES IN THE MANTIDAE AND PHASMIDAE OF 

 PANAMA (ORTHOPTERA) 



BY MORGAN HEBARD 



The present paper represents tlie third of our studies in the 

 Dermaptera and Orthoptera of Panama. ^ That section dealing 

 with the I^attidae required more general discussion and revision- 

 ary treatment, due to the larger percentage of undescribed forms 

 among the one hundred and six species now known- to occur in 

 the region. The sources of the material for the present studies, 

 acknowledgements, a brief discussion of the character of the 

 country, and a map showing the localities where the material 

 in question was taken, were therefore published in that pa])cr. 



In the first section of the present study the Alantidae are 

 treated, the collection again showing a high percentage of ihe 

 forms known from Panama. We are less fortunate, however, 

 in the second section, which deals with the Phasmidae, as but 

 sixteen species are represented, twenty-four other species having 

 been reported from this region. This decided deficiency, in 

 collections otherwise highly representative, is probably due in 

 part to the close resemblance of many walking-sticks to their 

 surroundings and their slow habit of movement, in part to the 

 fact that many live in the twigs and vine tangles of the forest, 

 where beating is most difficult and, as a rule, unproductive in 

 those orders of insects which were particularly sought by the 

 collectors of the greater portion of the material before us. 



In this paper two hundred antl eight Panamanian specimens 

 are treated, two new genera and four new species being de- 

 scri1)ed.
