the eye, the labrum exposed, the clypeus not defined, there being 

 only an nnpression or fovea on each side just above the labrum. 

 Mandibles truncate, one of the apical angles being more acutt 

 than the other, which is followed by minute microscopic ir denta- 

 tion, ])ut there are no true teeth, and the edge under high powers 

 of the microscope is very finely serrulate. Antennae elongate, 

 the scape long, clavate, extending above the vertex by about half 

 its whole length, which is equal to that of the following two or 

 three joints, the pedicel subtriargular about equal to the second 

 joint of funicle. the first funicle joint very long, about five times 

 as long as wide, and with the second clothed on one side with con- 

 spicuous erect hairs, which are curved and dilated apically, with 

 acute tips ; rest of antennae with inconspicuous subappressed hairs, 

 the third to the sixth joints of the funicle not differing much in 

 length, being barely one-third as long as the first, but wider than 

 this, club not evidently segmented, rather small, subequal to the 

 three preceding joints only. Thorax with the acute tips of the 

 axillae meeting inwardly, the scutellum very convex, compressed, 

 so as to be obscurely carinate in the middle, the propodeum 

 sparsely pilose at the sides. Wings with dark markings, the 

 neuration very difificult to see in part, but the marginal vein '"s 

 short, the stigmal moderately long, very oblique ( i. e. more lon- 

 gitudinal than transverse), the nostmargiral as long as the stig- 

 mal or a little longer. Hind tibiae apparently with no trace of 

 a second spur, the calcar of the mliddle lesfs not so long as the 

 first tarsal joint. Ovipositor not prominent.

Dark brown, inclining to black in parts, antennae except the 

 scape black or nearly so, abdomen also very dark or black, with 

 the faintest trace of metallic tinge in some aspects ; the insect 

 generally being not at all metallic. 



Head somewhat shining, there being a microscopic surface 

 sculpture and some very feeble fine punctures, most noticeable 

 on the front, about the eyes. Mesonotum slightly shining, clothed 

 with short pale hairs, and having a feeble indefinite puncturation ; 

 scutellum with sparse longish hairs at the apex, where it extends 

 over the propodeum. which is smooth and shining on the convex, 

 or somewhat protuberant, sides. Wings mostlv hairless on about 

 the basal half ; two-thirds from the base of this hvaline portion 

 apically is a narrow transverse dark bar, densely hairy, extending 

 from the submarginal vein, but not touching the costa, nor reach-
