THE CANADIAN ENTOMOLOGIST. 303 



Perdita halictoides, Smith. 



Type : Abdomen very dark brown, almost black ; nervures and 

 stigma sepia, strongly defined ; marginal cell with the poststigmatal part 

 hardly as long as the substigmatal ; metathorax and sides of thorax dark 

 blue, but the prothorax, mesothorax and scutellums practically black, 

 tinged with aeneous ; face more or less greenish, with no light marks ; 

 mandibles fulvo-ferruginous, scape reddish ; legs dark brown, femora 

 darker. Nearest to P. cBnei/rotis, Ckll. 



Pseudopanurgns andrenoides (Smith). 



Scrapter andrenoides, Sm., type % . — Rugose, with pale fuliginous 

 wings, head and thorax almost nude; marginal cell truncate; stigma' 

 large, brown ; first recurrent nervure enters second submarginal cell a 

 _ long way from its base; second recurrent joins cell at its extreme tip; 

 basal nervure falls short of transverso-medial by a moderate distance ; 

 maxillary palpi 6-jointed ; first joint of labial palpi somewhat shorter than 

 the other three united ; facial fovete club-shaped in outline, smooth and 

 shining ; no raised nodule on vertex ; process of labrum broadly truncate; 

 mandibles reddened ; clypeus densely punctured, except a narrow median 

 line ; punctures of mesothorax minute and extremely numerous, though 

 quite distinct ; the abdomen has not the large coarse punctures of some 

 forms of Pseudopanurgiis ; tegulre shining testaceous ; basal half of the 

 abdomen with a strong reddish tinge; hind legs slender; hind tibial scopa 

 thin but abundant. The truncation of the marginal cell is not nearly so 

 oblique as in Panurginus Cressojiielliis. 



Nomiafansta (Smith). 



Andrena fausta, Sm., type ? . — Natal. Third submarginal cell at 

 least as large as first ; enclosure of metathorax practically reduced to a 

 transverse band ; head and thorax with very dense large punctures; basal 

 joint of hind tarsi with the apical margin very oblique, second joint 

 triangular ; tegulae with a little keel behind. Colours like those of Noniia 

 rubella, Sm. Also examined by Col. Bingham, who agrees with me that 

 it is a Nomia. 



Prosopis. 



6- 

 Supraclypeal mark well developed ; lateral face-marks extending upwards 



along eye-margin ; scutellum yellow i. 



I. Marginal cell and beyond fuliginous ; sides of clypeus, except basally,
