 distinctly shorter than the 4th ; the apex of the clypeus is transverse, the sides

In Handlirsch's Monograph (Sitz. der Kaiserl. Akad. der Wissen.

IVoinia tacita sp. nov. 



Black ; the scntellnm, the apical half of the niesopleurje, the median segment 

 the basal abdominal segment, the base of the 2nd broadly and tlie 4th and 5th 

 more narrowly, bright metallic green ; the hinder trochanters with a large stout 

 tooth beneath ; the hinder femora with an oblique sharp tooth near the apex and 

 with a minute one between it and the apex ; the antennal joints dilated beneath ; 

 the clypeus is for the greater part white, % . Length 13 mm. 



Antenna? black ; the basal 5 joints rufous beneath ; the 4th to the 11th joints 

 are dilated roundly below and depressed roundly above ; the last joint is narrowed 

 at the base and becomes grarinally, but not much, narrowed towards the apex ; it 

 is slightly longer than preceding. Head black ; the face and outer orbits metallic 

 green, and thickly covered with long pale fulvous hair; the clypeus and the 

 mandibles, except at the apex, pale yellow. Eyes large, slightly, but distinctly, 

 converging below and thickly covered with dark fulvous pubescence. Thorax 

 thickly covered with long pale fulvous hair; the scutellum, the apical half of the 

 mesopleurseand the median segment bright emerald green ; the area on the median 

 segment is stoutly, irregularly reticulated ; the apical slope is closely, irregularly 

 punctured ; raetapleurpe closely, distinctly and finely punctured. The four front 

 femora and tibiffi and the front tarsi are rufo-fuivous; femora and middle tibise 

 lined with black behind; the hinder legs are entirely black; the trochanters 

 project below into a broad plate-like tooth, which becomes gradually narrowed 

 from the top to the bottom, the latter being rounded ; the hinder femora are 

 thickened, thicker at the apex than at the base; the tooth is sharply pointed 

 and about twice the length of the base ; the tibiae are stout, but not much thick- 

 ened towards the apex ; the metatarsus is stout and, on the upper side, beyond 

 the middle is produced into a stout tooth, which, above, becomes gradually roundly 

 narrowed towards the apex ; below it is straight ; the apical 3 joints are rufous ; 

 all legs are thickly covered with pale fulvous pubescence. Wings hyaline, the apex 

 infuscated ; the stigma testaceous, the nervures darker in color. The abdomen 

 is sparsely covered with pale pubescence with longer black pubescence on the 

 apical half of the 1st segment; the 2nd, 3rd and 4th segments are depressed at 

 the base; the last segment, in the middle, projects into a broad rounded lobe.

Noinia cillaba sp. nov. 

 Metallic bright green, mixed with blue; the apex of the clypeus, the labrum, 

 the mandibles, except at the apex, and the greater part of the legs, fulvous-
