360 MANTIDAE AND PHASMIDAE OF PANAMA 



Rio Trinidad, Puiuima, III, 29, 1912, (Busck), 1 small juv.; 

 V, 1911, (Busck), 1 9, eggs. 



The irregular, foliaceous lamellae of the body and limbs of 

 this very remarkable insect, like the long silky hairs on its 

 eggs, must closely resemble the mossy environment in which 

 the species probably lives. 



Bacteria ploiaria (Westwood)

The two males before us are unquestionably conspecific, 

 one having elongate wings, the other with these organs slightly 

 surpassing the median segment. The latter condition was 

 described as subvolans by Redtenbacher, the material before us 

 showing that name to be based on such individual variation 

 and consequently of no value. 



The previously unknown female may be described as follows. 

 Vertex weakly bituberculate, much as in male but with tuber- 

 culations proportionately not as heavy. The metatarsi are 

 cristate, as in B. remphan Westwood. The mesonotum is 

 granulose and weakly tectate. The median and caudal femora 

 are simple, except for a low lobe proximad on the ventro-caudal 

 margin of the sinistral median femur. The lobes of the limbs and 

 abdomen are subject to great individual variation in many 

 species of this and allied genera. The genitalia are much as 

 figured by Westwood for remyhan, except that the operculum 

 and the ultimate tergite reach an equal distance caudad, the 

 former not considerably surpassing the latter, while the sixth 

 tergite has the ventro-caudal ))ortions laterad produced in an 

 elongate rounded lobe, which does not jiroject beyond the 

 caudal margin of the tergite.
