166 Mr. T. D. A. Cockerell — Descriptions and 



few indistinct raised lines; other differences are, hind tibiBe 

 cream-coloured at base, creamy-white lateral face-marks 

 linear. The metathorax may be all red at sides or only red- 

 spotted. This is perhaps only a subspecies of P. lateralis. 



Hah. Mackay, Queensland, at flowers of XantkorrJicea 

 April 1899 (Turner, 856). British Museum. Another, col- 

 lected Nov. 1893, bears the number 858. 



There are two small cream-coloured marks on upper 

 border of prothorax. A variety (Turner, 858, Nov. 1893) is 

 larger and more robust (about 6 mm. long), with the stigma 

 honey-colour and the metathorax red except the enclosure. 

 The lateral face-marks are broader, as in lateralis.

Pachyprosopis mirabilis, Perkins. 



? . — Mackay, Queensland (Turner, 868). March and May 

 1900 ; one is from flowers of Eucalyptus. The mesothorax 

 and scutellum vary from dark green to dark purple. 



Pachyprosopis plebeia, sp. n. 



? . — Length 6^-7 mm. 



General build and appearance much as in P. mirabilis, but 

 the head, while thick, is not in any way extraordinary, being 

 as in Euryglossa. Head black, face broad; labium and 

 mandibles (except apex) dark red ; clypeus with distinct 

 well-separated punctures, front minutely punctured ; linear 

 facial fovese curving above and running to lateral ocelli ; 

 scape light orange ; flagellum thick, entirely clear ferrugi- 

 nous ; thorax black, with the very minutely punctured 

 mesothorax tile-red, sometimes clouded with black at sides ; 

 scutellum with minute punctures on a shining ground, its 

 anterior border sometimes red, area of metathorax not 

 noticeably sculptured, sides of metathorax with conspicuous 

 white hair; tegulaj very dark brown. Wings clear, nervures 

 and stigma yellowish brown; venation as in P. mirabilis, 

 but the second s.m. is not so narrow, and the basal nervure 

 is more arched. Femora black, ferruginous at apex ; tibise 

 and tarsi clear ferruginous, the anterior tibiae more or less 

 yellow in front. Abdomen red, a shade darker than in 

 P. mirabilis, the first segment sometimes blackened basally, 

 when two small orange spots appear upon the black.
