median ridge and changing to very closely lineolate on each side ex- 

 terior to the antennal sockets and on the cheeks ; vertex much more 

 finely but more rugosely reticulate, gradually becoming almost smooth 

 on the frons, an orbital row of very fine, shallow pin-punctures on each 

 side of the frontovertex, and a few scattered over the frons ; meso- 

 scutum distinctly reticulate with the lines running transversely; axillae 

 transversely lineolato-reticulate ; scutellum with crowded, microscopic 

 thimble-like punctures appearing granular at lower magnifications and 

 opaque in most aspects, the obliquely sloping latero-apical margin 

 smooth and highly polished; metanotum and propodeum smooth, the 

 metapleura highly polished ; mesopleura finely reticulate with the lines 

 running mostly lengthwise ; abdomen smooth and shiny, the apical ter- 

 gite, however, rather rugosely reticulate except on the sides. (Diaspidis 

 has a smoother face with the reticulations indistinct except on the 

 facial ridge, and the thimble-like punctures of scutellum appear to be 

 slightly coarser). 



Eyes with very sparse and extremely short pile ; pubescence on other 

 parts of head also short and sparse, yellowish white in color and con- 

 fined to the frontovertex and lower part of the face; that on the 

 thorax blackish and rather sparse and short on the mesoscutum, mucli 

 longer on the scutellum and more bristle-like especially towards the 

 apex, the four scale-like bristles at the apex very narrow and all nearly 

 equal in length (in diaspidis these bristles are comparatively wide with 

 the anterior pair nuich the shorter) ; pubescence on the basal corners of 

 the propodeum, the sides of the abdomen and on the protruded part of 

 the ovipositor sparse, fine and pale-colored. 



Length: (0.80 to) 1.03; width of vertex at the anterior ocellus: o.ioi; 

 width of mesoscutum: 0.433; length of fore-wing: 1.03; width of ^ore- 

 wing: 0.436; length of protruded part of ovipositor: 0.113 mm. 



General color metallic bluish black, the luster of head bluish, be- 

 coming purplish on the sides of the face and greenish on the facial 

 ridge ; luster of thorax mostly bluish or bluish-green and slightly 

 purplish in part, the scutellum usually appearing dull black, its apex, 

 however, the lateral margins as well as the metapleura brilliant metallic 

 green and brassy ; abdomen brilliant metallic green on the first tergite 

 and lateral margins near apex, the remainder with various metallic 

 reflections but usually dark purplish and bronzy. Basal half of the 

 scape, pedicel except at apex, first two funcle joints and club black; 

 the rest of scape, apical third of pedicel and last two funicle joints 

 yellow. Legs mostly yellowish white with the front and hind coxae 

 and femora except at base black, the middle femora wiih a narrow black 

 ring just before the apex and rather indistinct on the under side ; front 

 tibiae with a l)lack ring reaching about to the middle, the base nar- 

 rowly white ; a similar ring on the middle tibiae only slightly wider than 

 the preceding white base and falling considerably short of the middle ; 

 hind tibiae with a broad black ring reaching a little beyond the middle 

 and leaving the base narrowly white; the tarsi slightly more yellowisli
