beneath, and the tip of the last joint blackish. Wings hyaline, the 

 veins yellowish but the stigmal and the submarginal except at base' and 

 apex are much more transparent tlian the rest of the \'enation. 

 Male: Not known. 



Described from four fouuiles (type and paraty})es) col- 

 lected at Ximanu Pali, Oaliti, Oct. 19, 1919 (W. M. Gif- 

 fard). 



This species is very similar to Plagioiumis did^pidis 

 Crawford but can be distinguished by the nearly bare ri^'es. 

 the narrower wings and frontovertex and l)y the slender 

 lamelliform bristles on the scntelhim. The coloration is siiii- 

 ih'.r but the black band on the middle femoi-a is much iiar- 

 I'liwer. 



The host of Iwspes is unknown but judging from the habits 

 of other nuunbers of the genns it shotild prove to be a l)ias]-)ine 

 scale. The species is no doubt immigrant and presumaldy 

 came from some part of America as the genus has not heen 

 recognized hitherto outside of Xorth America. As no males of 

 PJa(/lo)iieriis have been discovered it is becoming apparent that 

 the sj»ecies nre thelyotokons and maleless under ordinary cir- 

 cumstances.

Female: Head as seen from tlic side distinctly triangular .and as 

 seen from above almost perfectly semicircular in outline ; the dorsal 

 surface much flattened especially in the longitudinal axis, its plane 

 forming an acute angle witli the strongly obliquely inclined ventro- 

 anterior surface although the angulation is somewhat rounded oflf; 

 eyes and frons not entirely dorsal but continued distinctly beyond the 

 angulation on to the ventro-anterior surface ; anterior orliits of the 

 eyes with a distinct but narrow furrow continuous across the face 

 between the eyes, thus marking the anterior boundary of the frons and 

 lined throughout with silvery white, siiort and recumbent hairs. 

 Antennae rather short and stout, the scape compressed and a little wid- 

 ened towards the apex, the pedicel rather short and thick, the funicle 

 six-jointed with the joints mostly transverse, the clui) sligbtlx longer 

 than the funicle. 



Thorax depressed, the mesoscntum l)eing very flat; scutellum a little 

 wider than long, at apex nearly rectangular and without any bristles. 

 Abdomen triangular as seen from ;i)iov.'. a little narrower tiian tiie
