parts; occiput broadly emarginated. PI. 11. Fig. 4, Head Br. 0,57 mm. 

 Length 0,23 mm. The breadth of the forehead between the eyes 

 0,25 mm. ; the occiput between the eyes 0,46 mm. Pronotum L. 0,16. 

 Br, 0,36 rounded in front and posteriorly. Mesonotum L. 0,13 mm. 

 Br. 0,43 mm. Elytra L. 0,45 mm. Br. 0,1 mm. Metanotum. L. 1,22 mm. 

 maximum Br. 0,51, with praescutum not completely separated from 

 the scutum. Postlumbium L. 0,11 mm. Br. 0,35 mm. Postscutellum 

 slightly constricted at the base rounded at the tip L. 0,6 mm. 

 Br. 0,20 mm. The abdomen L. 1 mm. The last abdominal tergite 

 transverse L. 0,1 mm. Br. 0,17 mm. ; slightly carved at the apex, 

 laterally broadly rounded PI. III. Fig. 5 A. Oedeagus short, stout, 

 curved PI. III. Fig. 5 B; it differs from that of P. neomexicanus 

 Pierce (the only species in which genitalia are known) in being 

 much stouter and shorter; strongly bent, right angled at the 

 inflated base with sharply reflexed apex, the inner angle is acute. 

 The oedeagus of P. neomexicanus Pier ce is much longer slender 

 not as strongly bent as that of Shaumii Saunders its basal 

 angle is obtuse, and the inner apical one is right. Unfortunately 

 in all four male specimens, extracted from the puparia the wings 

 are folded in such a manner that it is practically impossible to 

 study the venation. 



Female. PI. III. Fig. 6 E. Described from an adult female 

 larva, wich was compressed among growing male puparia so that 

 it was badly damaged. I was therefore unable to obtain the most 

 important measurements viz. the distance between the spiracles 

 and the breadth of céphalothorax at the base. The larval cépha- 

 lothorax was yet white with brown spiracles, mandibles and patches 

 on both sides of the head. L. 0,775 mm. L. from the spicale to 

 the apex of the cephalathorax 0,68 mm. Breadth of the head 

 0,58 mm. Br. between the mandibles 0,16 mm. Mandibles Br. 

 0,027 mm. L. 0,046 mm. elongate with a tooth outwardly recurved 

 at the apex. PI. III. Fig. 6 F. The transverse slit unconspicuous. 

 The orifice of the mouth situated before the mandibles. 



Triungulinid larva. Described only from one larval skin found 

 in the viscera of the wasp host. The larva was decapitated as 

 occurs usually during the metamorphosis, when the second stage 

 larva emerges from the triungulinid by casting off the head skin. 

 Yet the head skin was been also found and the drawing below 

 PI. III. Fig. 7 A — C. represents a reconstruction of the whole larva.
