second pair of lobes minute, bluntly pointed, entire; 

 third pair of lobes smaller than second, pointed, pec- 

 tinae and plates subequal in length to median pair of 

 lobes, arranged 2, 2, 3, 2-3, those of median incisura 

 and each lateris slender plates, those of second and 

 third incisurae longest, furcapectinae; densariae of 

 second incisurae larger than those of third, wanting 

 in median ; anus large, about its own width from 



caudal margin. — Argentina on Ophryoporus 



argcntina Leon, 

 ff. Pygidium with anus large, over three times its width 

 from caudal margin; median pair of lobes large, quad- 

 rangular, deep lateral and mesal notches, distal margin 

 strongly convexly rounded between notches; second pair 

 of lobes small, rounded, inconspicuous; third pair of 

 lobes rounded, smaller than second pair, inconspicuous; 

 pectinae not deeply lacinate, about as long as median 

 pair of lobes, arranged 2, 2, 3, 2-3, those of third in- 

 cisurae and of lateres either not deeply lacinate or 

 plates, one of each third incisura much larger than 

 others; densariae prominent, those of second incisurae 

 larger than those of third, mesal and lateral margins 

 subequal; spiracerores wanting; each lateris on caudal 

 portion with short plate-like projections; pygidium of 

 second nymphal female similar to adult. — Tanga, Africa 



on Tectona. tectonae Lindgr. 



ee. Pygidium with median pair of lobes not well developed, 

 margin rounded; second pair of lobes represented by sim- 

 ple lobe of border of pygidium; third pair of lobes spini- 

 form; pectinae furcapectinae, arranged 2, 2, 3, 2; pectinae 

 of median incisura but little longer than median lobes, 

 others successively longer, those of each lateris twice as 

 long as lobes, formed with mesal fork much longer than 



lateral. — France on Psamma provincialis Vayss. 



CO. Pygidium with five to seven pectinae on each lateris. 



d. Pygidium with densariae in median incisura; median pair of 

 lobes subquadrangular, longer than broad, entire, truncately 

 rounded, distant; second and third pairs of lobes much 

 smaller, short, entire, bluntly rounded; pectinae elongate, 

 nearly twice as long as median pair of lobes, deeply lacinate, 

 arranged 2, 2, 3, 5-6, those of each lateris very deeply 

 lacinate; anus about four times its width distant from caudal 

 margin; setae of median and second pairs of lobes long, 

 longer than lobes; densariae of second and third incisurae 



typical. — Canary Islands on Euphorbia. taorensis Lindgr. 



dd. Pygidium not with densariae in median Incisura; median 

 pair of lobes longer than broad, subadjacent at proximal end, 

 bluntly rounded, entire; second and third pairs of lobes 

 large and distinct, smaller than median pair, bluntly pointed, 

 indistinct lateral notch; pectinae elongate, distinctly longer
