armed -with microscopic brown tubercles. Figure 69 shows the larvae 

 about one-half grown, and Figure 73 the full-grown grub in an apple- 

 seed which has been cut open. 



Pupa. — The pupa is white at first and in the female has the ovipositor 

 turned upon the back, extending almost to the head. When nearly 

 ready to transform it becomes darker colored. (Fig. 70). 



Adult. — Figure 74 shows the adult female. Because of the confusion 

 in regard to the identity of this species the following technical des- 

 cription is presented: 



Female. — Length 3-3.5 mm.; thorax, 1.3-1.6 mm.; abdomen, 1.7 

 mm.; ovipositor, 4 mm. 



Head, thorax and abdomen green with brilliant metallic reflections. 



Head seen from above transverse, convergent behind the eyes, slightly 



concave in front and behind; seen from in front a little broader than 



high; base of antennae 

 separated by a median 

 carina which becomes 

 indistinct below; an- 

 tennal grooves con- 

 fluent, lateral margins 

 convergent above, 

 polished; clypeus not 

 distinct, smooth, 

 truncate. Sculpture 

 of head a fine, irreg- 

 ular shingling becom- 

 ing on the face 

 and along the eye- 

 border finely and closely pustulate. Head clothed with sparse white 

 hairs arising from shallow punctures, more abundant near margin of 

 mouth. Mandibles tridentate; lower tooth angulate. 



Sculpture of thorax consisting of short, irregular, transverse ridges 

 so arranged as to give a shingled appearance to the surface. This is 

 most pronounced on the pronotum but posteriorly it becomes finer and 

 gradually changes to closely pustulate on the scutellum and on the 

 lateral parts of the pronotum. Whole thoracic dorsum with scattered 

 shallow punctures from which arises small light-colored hairs. Scutellum 

 behind the transverse stria polished but also very delicately sculptured. 

 The pleural sclerite behind the femoral furrow smooth and polished, the 

 one in front finely reticulate. Propodeum with a row of deep punctures 

 on the anterior margin and with a narrow ridge along the posterior edge;
