growth not so pronounced; pale Ijrown in color; irregular whitish flattened 

 border almost wanting; ventral scale incomplete. Length about 1.5 mm. 



Adult Female. — Long elliptical, lateral margins nearly straight, slightly 

 wider toward posterior end. The last abdominal segment presents the follow- 

 ing characters : The anterior group of spinnerets are six ; the anterior laterals 

 about seven, and the posterior laterals about nine. The median lobes well 

 developed with the margins crenate, the second lobe deeply incised, the 

 margins of the lobules crenate ; the third lobe is wanting. The plates are not 

 very large, but prominent and simple, tapering ; there are two of them in each 

 of the following places : between median lobes, between first and second 

 lobes, and several more beyond the second lobes. Spines prominent, one on 

 the liase of each lobe. Length about 1.65 mm., width .5 mm. 



Buzen, Kiushiu, on vine, collected by the writer, June, 1907. 



The present species is allied to Mytilaspis gloveri Pack., but the 

 large second exuvia and rather short scale widening" gradually toward 

 posterior extremity are good characters for separating it from the 

 latter. 



17. Mytilaspis (Lepidosaphes) uniloba, new species. (PI. IX, Figs. 42-45.) 

 Female Puparium. — Long and narrow, straight or curved ; sides almost 

 parallel, but slightly widening toward the posterior extremity, with whitish, 

 narrow, flattened border. Color dark brown, with pale margin ; the older 

 specimens pale white. Pellicles pale yellow, occupying about one third the 

 total length of the scale. The first exuvia oval, about .3 mm., cross ridges 

 well marked ; second exuvia large, about .6 mm. Ventral scale incomplete. 

 Length 2-2, mm., width about .5 mm. 



Male Puparium. — Unknown to the writer. 



Adult Female. — Pale yellow, with the last abdominal segment yellow ; 

 elongate in form, lateral margin straight, and approximately parallel ; the 

 abdominal area being wider than the anterior parts. The abdominal segments 

 short, the lateral margins not much produced ; next to the last abdominrJ 

 segment with two stout, spine-like processes and many short spines. The 

 last abdominal segment presents the following characters : The anterior group 

 of spinnerets four, the anterior laterals ten to twelve, and the posterior 

 laterals eleven to fourteen (some specimens show three or four more groups 

 of spinnerets above the anterior group, which is shown in the figure). There 

 is only a single lobe which is very large and crenate ; four simple plates on 

 each side, two of them are very large, while the other two are smaller. 

 Length about 1.5 mm., width about .5 mm. 



Habitat. — Hiogo, on Osmantlms, collected by the writer, March, 

 1907. 



This species can be readily distinguished from all others in the 

 genus by its single median lobe. The supplemental gland pores or 

 spinnerets, shown in the figure do not appear to be constant.
