TRIBE ASPIDIOTINI 451 



SPECIES OF STRINGASPIDIOTUS 



Pygidium with four pairs of lobes; median pair large, conspicuous, 

 pointed, mesal and lateral notches; second and third pairs of lobes 

 narrow, lanceolate, constricted at proximal end; fourth pair of 

 lobes broad, distinct, mesal and lateral notches; pectinae subequal 

 in length to lobes, arranged 2, 2, 3, 3, 0; each lateris irregularly 

 dentate; mesospiracerores 3-4; anus distant from caudal margin; 



genacerores (12-12)12-12. Java on Curculigo curculiginis Green. 



Pygidium with three pairs of lobes; median pair of lobes as broad 

 as long, distal end bluntly rounded, lateral notch deep, mesal notch 

 faint; second pair of lobes with lateral margin in part oblique, mesal 

 and lateral notches faint; third pair of lobes three times as long, 

 pointed, spine-like; pectinae arranged 2, 2, 3, 5, those of incisurae 

 distapectinae, those of third incisurae very broad, those of each 

 lateris unapectinae; setae short, not one-half length of lobes; body 

 with mesal part of cephalic margin toothed or deeply crenulate; 

 genacerores (4-9)6-6; anus distant from caudal margin. Selenaspidus 

 ferox Lindgr., Selenaspidus articulatus celastri Mask. Cape of Good 

 Hope, Gold Coast, Africa on Celastrus, Plumiera-like Euphorbiaceae. 



celastri Mask. 



SPECIES OF SEMELASPIDUS 



Pygidium with anus distant from caudal margin about twice its 

 length; median pair of lobes small, rounded, entire; second and third 

 pairs of lobes smaller, slightly notched; second and median pairs 

 of lobes much closer together than second and third; each lateris 

 irregularly serrate; paraphyses four in number on each side, slender, 

 median pair longest; pectinae narrow, obscurely lacinate; meso- 

 spiracerores numerous; genacerores in threa groups, median 4-6, 

 lateral 3-6. India on leaves of unidentified tree.triglandulosa Green. 

 Pygidium with anus distant from caudal margin about three times 

 its length; median pair of lobes triangular, bluntly pointed, sides 

 slightly emarginate; second pair of lobes smallest, near median pair; 

 third pair of lobes triangular, larger than median pair; pectinae 

 small and inconspicuous; paraphyses four in number on each side, 

 median pair slightly longer than others, these subequal; each lateris 

 with prominent serrate projections; genacerores in three groups, 

 median 2-4, lateral 2-5. Ceylon on Cinnamomum.__cistaZoide* Green. 

 Aspidiotus capsulatus Green from Java on Piper has a similar scale 

 and undoubtedly belong to this genus. 



SPECIES OF SELENASPIDUS 



Body with cephalic margin entire or finely or distinctly serrate, 

 never crenulate with projections of two sizes. 



b. Body with mesothoracic marginal spine suddenly drawn out, 

 conical, bluntly pointed, length about equal to greatest width; 

 median pair of lobes entire, rectangular, frequently with faint 

 lateral notches, distal end bluntly rounded, longer than broad; 

 second pair of lobes broader than median, subequal in length, 

 lateral margin obliquely rounded, one or two notches, distal end
