therefore remain as the types. Peryassu (1908) describes the 

 male, but briefly and without reference to the genitalic 

 structures. Dyar (1918) was therefore unable to place the 

 species. 



In going over the collection I made the fortunate discovery 

 of a male from Sao Paulo, Brazil, sent by Dr. Lutz. The 

 localities are somewhat remote ; but it is possible that the 

 species ranges throughout tropical Brazil, and as Dr. Lutz is 

 known as a careful student and Theobald's female types are 

 indefinite, I propose to consider this as the male of indecora- 

 bilis as identified by Dr. Lutz. 



Theobald (1910) records the species from Georgia, on the 

 strength of a specimen received from Dr. Ludlow ; but this 

 identification is wholly improbable.

The genitalic structure is distinct from any of the species 

 noticed by me (Ins. Ins. Mens., viii, 54-81, 1920). The 

 structure which I called the third point of the mesosomal 

 plate forms a distinct hook, but wholly separated from the plate 

 itself, arising from the base. The mesosomal plate remains as 

 a ligulate rod with pointed tip, without any emargination at 

 apex. 



Side pieces moderately swollen, the tip slender and curved. 

 Inner division of lobe of side piece with two filaments with 

 expanded hooked tips, the shaft rather long, one filament in- 

 serted at the tip, the other half way on the shaft. Outer 

 division of lobe of side piece nearly evenly furcate, the limbs 

 well separated ; a stout but short seta on the shaft ; inner limb 

 with a long filament with hooked tip, and a short filament ; 

 outer limb with a bunch of filaments, which may be four or
