tions to prout’s brown. Limbs warm buff, the coxae each with a conspicuous 
but small blotch of mummy brown proximad and distad; the sjiines russet;

blotches of mummy brown at bases of spines and suffused distad with this 
color, the tarsi washed with tawny. Ventral surface of male abdomen mummy 
brown paling to dresden brown laterad and ochraceous-buff latero-sinistrad, 
the subgenital plate being suffused with mummy brown proximad and dex- 
trad to near margin at point of greatest production, the remaining jKjrtions 
ochraceous-buff. Ventral surface of female abdomen blackish mummy 
brown ])ahng to ochraceous-buff laterad, with a blotch of mummy brown on 
each .segment, the subgenital plate shining blackish mummy brown, except

Tlie male here recorded agrees fully with a male recently taken 
in the C'anal Zone, Panama, by the author. Females from the 
C'anal Zone accord throughout with the original description of 
festae and undoubtedly represent the opposite sex of the males 
mentioned above. It is further evident that, though the females 
recorded l)y us and descrilted as this species in 1916,-^ were cor- 
rectly assigned, the male there descril)ed as festae represents a 
distinct sf^ecies, which we here name Xestoblatta hoplites^^ 
As the male sex of the present species was previously unknown, 
we give the following description of this remarkable insect, which 
shows the highest specialization of the fourth, fifth, sixth and 
seventh al)dominal tergites we have found in the Blattidae. 
Size medium, form moderately broad, rather slender for the genus. Inter- 
ocular space (.9 mm.) slightly over half as wide as space between antennal 
sockets. <4cellar areas very weakly defined. Pronotum as characteristic 
of genus, but not j)roportionately fully as broad as in festae. 
Tegmina and wings fully developed, with venation as characteristic of 
Xestoblatta, with intercalated triangle broad, as in carrikeri. Wings with 
-^Trails. .\m. Ent. Soc., xui, p. 377.
