Sphecodes banksii n. sp. 



9 - Length 3-4 mm. Head and thorax black ; abdomen red, the 

 apical segments clouded with black. Head about as broad as long; 

 mandibles simple, yellowish-red the apices darker ; face finely and dense- 

 ly punctured, clothed with thin, white hair ; labrum sometimes reddish, 

 clypeus smooth and shining almost impunctate ; antennae brownish- 

 black, flagella reddish brown. Mesothorax smooth and shining, with 

 small, sparse punctures; tubercles red. Enclosure of metathorax well- 

 defined, with parallel ridges. Wings hyaline faintly tinged with fus- 

 cous, iridescent, nervures and stigma fuscous ; tegulae reddish testa- 

 ceous ; second submarginal cell narrow, the sides nearly parallel. Legs 

 reddish-brown, clothed with silvery white hair. Abdominal segments 

 1-3 light or yellowish-red, the apical segments not deeply shaded with 

 black; basal segment with a few fine punctures, the other segments 

 finely and closely punctured all over except on the apical margins. 



The description is based on four female specimens from 

 Sea Cliff, Long- Island. X. Y., N. Banks. This is a very 

 distinct form and I know of no other species in North Amer- 

 ica with which it can be compared. The species is dedicated 

 to Dr. Nathan Banks. 



Sphecodes distolus n. sp. 



9. Length 6 mm. Head and thorax black; abdomen largely red, 

 the apical segments only partially black. Head broader than long; 

 mandibles red with darker apices, bidentate ; clypeus without a median 

 suture, with small rather close punctures ; face very finely and densely 

 punctured; antennae black, flagella reddish brown, joints 3 and 4 nearly 

 equal. Mesothorax finely and densely punctured, wings hyaline, stigma, 

 nervures and tegulae pale fuscous, the first transverse cubital nervurc is 

 absent and there are only two submarginal cells, the first of the two cells 

 is nearly three times the length of the second, the venation (except the 

 radial nervure) beyond the basal nervure is subobsolete. The en- 

 closure of the metathorax is well-defined, the center smooth and shining
