 Figure 174 



Length of male 9.1 mm.; of female 8.4-9.3 mm. Head with median 

 length of crown approximately two-fifths greater than interocular 

 width, and approximately equal to transocular width, with a median 

 fovea extending almost full length of crown and slightly broadened 

 anteriorly, without an apical carina between crown and face; antennal 

 ledges in lateral aspect with a very shallow longitudinal depression, 

 anterior margin sloping gradually to contour of face ; clypeus flattened 

 medially. Pronotal disc punctate on posterior three-fourths; scutellum 

 transversely striate on posterior portion. Forewings of female at rest 

 scarcely exceeding apex of ovipositor, coriaceous, with membrane 

 including all of apical cells; clavus closely and corium sparsely punctate 

 in basal half. Male pygofer elongate and with apical margin weakly 

 convex ; plates each triangular, extending posteriorly about half length 

 of pygofer; style short, extending posteriorly beyond apex of connective, 

 somewhat rounded apically; aedeagus with basal portion inflated, 

 giving off" three pairs of slender tapering processes. Female abdominal 

 sternum VII with posterior margin bearing a median acutely angular 

 excision (fig. 174i) which does not include the whole posterior margin 

 as it does in P. aterrima Fowler. Color of anterior dorsum brick- red,
