National Museum at Washington, D. C, which specimen was 

 unquestionably accidentally introduced. 



The present series enables us to synonymize Burmeister's Holo- 

 compsa cyanea, which was based upon males of the species, while his 

 Holocampsa collar is was described from individuals of the opposite 

 sex. The latter species was first recognized as a synonym of Holo- 

 compsa nitidula by Kirby in 1904. ^^ Previous authors have failed 

 to recognize cyanea and collaris as sexes of the same species owing, 

 apparently, to their lack of sufficient material. The males are 

 rather slender and almost uniformly shining blackish (the antennse 

 have three pale yellowish joints in the distal portion and the limbs 

 are very dark brown), while the females are much more robust, the 

 pronotum is strikingly cinnamon-rufous and the tegmina are a very 

 dark metallic blue in the colored portion; in the latter sex somewhat 

 more than the distal half of the antennae is pale yellowish. Such 

 striking differences between the sexes explains their being described 

 as different species in the same paper. 

 Plectoptera poeyi (Sauss.).

On Big Pine Key the species was beaten from a fringe of tall 

 bushes growing on the edge of a mangrove swamp, where individuals 

 were scarce. The insects were found fairly common on Key West 

 in rather scattered bushes, particularly Ilex cassine. One nymph 

 was also taken at night at the latter locality, running about on the 

 leaves of a buttonwood bush {Conocarpus erecta). 



MANTID^. 

 Mantoida maya S. and Z. 



Key West, Fla., July 7, 1912; 19. 



This is the second United States record of this peculiar mantis, 

 which was described from Temax, northern Yucatan. The first 

 record from within the United States was given with certainty from 

 Florida and probably from Kissimmee.^^ The present specimen 

 fully agrees with the original description and was taken while swiftly 

 running about on the ground under high jungle brush. 

 Stagmomantis Carolina (Johannson).
