Kiiineii«'S (Alpha) eiiigniatus n. sp. (PL XII). 



%. — Differs from emarginilineatus as follows: tegulse partly, a spot beneath 

 latter on pleura, a sliort band on each side of metathorax, an elongate cuneiform 

 mark on each side of the second dorsal abdominal segment, a cone-shaped mark 

 on first ventral segment, a large helmit-like mark on second ventral segment and 

 a yellow apical line on each of the following segments, except the apical one, 

 yellow. In addition, the convexities of the metathorax are rather hemispheri- 

 cal and the petiole is broader.

Odynerus sulfuritiiictus n. sp. 



Related to scutelUiris, from which it can be readily separated by 

 the excavated metathorax, etc. 



9. — 13 mm. — Head. — Front distinctly punctured, the punctures adjoining and 

 placed in a shining tegument; clypeus and cheeks more shining and with their 

 punctures more separated than the dorsum of the thorax ; covered with pubes- 

 cence varying in color from brownish-gold to yellowish-gold, but nowhere 

 obscuring the tegument; black and yellow, the yellow confined as follows, a line 

 on basal half of mandibles, clypeus excepting the margins of the anterior half 

 and a triangular space in the middle, a spot between the insertion of the antennae, 

 the anterior aspect of the scape and an ovoid mark back of each eye ; vertex with 

 a deep pit posterior to the hind ocellus, giving the appearance of there being an 

 additional simple eye. 



Thorax. — Black and yellow, pubescent in much the same way as the head, its 

 pubescence of the same kind ; pronotum bordered with yellow along its anterior 

 margin ; anterior femora and tibiae partly yellow, the anterior tarsi almost com- 

 pletely yellow ; mesothorax above sculptured much the same as the front and 

 most of the remainder of the thoracic dorsum, its pleura more shining on account 

 of the punctures being more separated ; its yellow portions are as follows: a spot 

 immediately posterior to the tubercles on the mesopleura, all excepting the cen- 

 tral testaceous portion of the tegulse, the post scutel, middle and posterior coxae 

 anteriorly, middle and posterior femora in part, greater portion of its tibiae and 

 the middle tarsi almost entirely, the posterior tarsi brownish like the hindmost 

 portion of the adjoining tibiae, wings brownish, with a yellowish reflection, pos- 

 terior edge of postscutel with a series of short broad rather indistinct teeth;
