304 THE CANADIAN ENTOMOLOGIST. 



Lateral face-marks continued upwards along eye-margin ; clypeus with a 



broad central yellow stripe i. 



I. Scutellum black (Brazil) variolosa. Smith. 



Scutellum yellow vigilans, Smith. 



Frosopis trepanda, Smith, is a synonym of vigi/afis. 



Gastropsis. 



Ashmead puts this in the Andreninae, but it is really a relative of 

 Meliturga, and has, like it, terminal abdominal spines in the ^ , and the 

 same sort of eyes (though in Meliturga ^ they converge above) and the 

 same third antennal joint. They also agree in having the basal nervure 

 falling a long way short of the transverso-medial. They are, of course, 

 quite distinct genera, Meliturga being the more aberrant. Oxcea also 

 appears to be related. 



Gastropsis pubescens, Sm., $ . 



W. Australia ; the only known species of the genus. Its general 



appearance is very like that of the Peruvian Megacilissa vestita, Smith, 



but the venation, of course, is different. It has the broad second 



submarginal cell like that o( Ajithoglossa phimata, Sm., and like it has the 



stigma obsolete. First and second recurrent nervures enter middle of 



second and third submarginal cells ; third antennal joint very long; face 



narrow, with large eyes ; maxillary palpi 6-jointed ; area of metathorax 



very long and narrow ; abdomen very hairy, and rather tapering, with 



two terminal spines, which are sometimes folded back, and then not 



readily seen. 



Sphecodes dichroa, Smith. 



Type ? . Vertex with a low but quite observable tubercle just 

 behind the ocelli, and behind this are a number of transverse grooves or 

 strise ; mesothorax with large strong punctures well separated on a^shining 

 surface ; abdomen with distinct but only moderately close punctures, only 

 the last segment blackish ; area of metathorax strongly but not closely 

 longitudinally wrinkled, and with some irregular cross-wrinkles. 



Sphecodes pilosulus, Smith. 



Type 9 • Mandibles dentate ; metathoracic area semilunar, very 

 distinct, with a strong margin, and very strongly, closely longitudinally 

 ridged ; rest of metathorax hairy ; face hairy ; first abdominal segment 

 with a black discal patch. 



Sphecodes mandibularis, Cresson. 

 An apparently authentic $ in the Museum has the mandibles dentate.
