The other specimens of the species before us agree fully with the 

 above measurements. 



In coloration the present species closely resembles rotundipennis, 

 but the series before us is all rather dark and, in all but two females 

 from Isle of Hope, the dorsal portion of the lateral lobes of the prono- 

 tum including the metazona is blackish. 



The present species was found in a restricted area of a sandy tract 

 covered with various low bushy plants, such as Myrica pumila,Quercus 

 minima, gall-berry bushes and saw palmettoes (Jesup), and in scant 

 undergrowth of the slightly more elevated portions of the flat almost 

 swampy gray-bark pine woods (Sandfly, Isle of Hope). The species 

 was very scarce, long-continued and thorough search being made for 

 it at each locality where it was found.

This insect, which may be said to be the most aberrant of the Puer 

 Group, differs from all other species in this group in the shape of the 

 male supra-anal plate and furcula, which have been well figured and 

 described by Morse. 88 



A certain similarity to M. stegocercus in the form of the male sub- 

 genital plate is apparent, but in the present insect this plate distad 

 narrows considerably more and is also deflected dorsad, which gives 

 the apex of the abdomen a very different appearance (fig. 21). The 

 cerci suggest in contour those of M. minis, but are decidedly smaller, 

 less flexed and more simple in outline (fig. 20). It is interesting to 

 note that while stegocercus, minis and strumosus show a common an-
