Seventh tergum with a longitudinal carina on apical half, tip of tergum 

 projecting well beyond apex of hypopygium; apical central hook 

 of latter relatively small, not much curved at base and not standing 

 well clear of the sternum at base so that it is only visible as a hook 



under a moderate magnification 18 



18(17) Sixth tergum not longer than wide at base (fig. 19) . . subglobulata 



Sixth tergum distinctly longer than wide at base .... globulata 



19(3) Prothorax with two long spines above near middle (fig. 85) . spinata 



Prothorax without such spines 20 



20(19) Upper margin of hypopygium with a large apical process, standing 



clear from base (fig. 25) fenestrata 



Upper margin of hypopygium with a very small hidden apical proc- 

 ess 21 



21(20) Claspers each with a deep excavation on upper margin before apex, 



the lower margin entire; fifth sternum with regular microscopic 

 striae which run from base to apex and are slightly outwardly 



directed strigata 



Claspers each with a deep rounded excavation on upper margin before 



apex, and a deep incision about opposite on lower margin (fig. 27) ; 



fifth sternum lacking regular striae, granular, the granulations 



being partially grouped in irregular transverse rows . . patruela 



22(2) Abdomen nearly as wide at hypopygium as at any point proximad 



to it 23 



Abdomen notably widest at third or fourth segment; seventh tergum 

 remarkably elongated and slender, projecting beyond apex of hy- 

 popygium by at least the length of the latter 28 



23(22) Hypopygium almost annular, the terminal hook large, flanked each 



side by a space, which is not filled by the broadly triangular clasp- 

 ers; seventh tergum not especially narrowed subapically, apex a 

 strong process projecting well beyond hypopygium . . apiculata 

 Hypopygium more elongate, hook small, seventh tergum different . 24 

 24(23) Hypopygium scarcely inflated and but little deeper than abdomen . 25 



Hypopygium somewhat inflated, notably thicker vertically than 



adjacent part of abdomen 27 



25(24) Apical process of hypopygium exposed, short, vertical (fig. 23). 



borincana 

 Apical process of hypopygium if developed bent cephalad and hidden 



by claspers 26

inferior angle ica 



Claspers broader basally, rather pointed apically, superior angle 



sloped off with a long bevel pachitea

corrugated subapically, the apex pointed and slightly keeled (figs. 



5, 30) aracataca 



Seventh tergum shorter, but little narrowed and faintly transversely 

 wrinkled subapically, the apex triangular, bluntly pointed (fig. 



20) colona 



28(22) Abdomen widest at fourth segment, each tergum with a pair of 



small round spots of pale yellow pile on hind margin; spiracles 



yellow assanutrix
