second, the third joint is, if anything, slightly longer than the second 

 or fourth ; dorsulum with exceedingly fine and close punctures; 

 scutellum strongly convex, not impressed; metanotum with rather 

 strong punctures or granules, with a well-defined raised line extend- 

 ing from base to apex; metapleurse indistinctly striated; tibire and 

 tarsi not at all, the tarsi slightly perhaps, spinose, the fore tarsi with- 

 out comb ; abdomen shining much more finely punctured than the 

 dorsulum ; wings hyaline, the anteriors with their apical margin 

 broadly fuscous, nervures black, marginal cell distinctly shorter than 

 the first submarginal, second recurrent nervure received by the 

 second submarginal cell near its apex; black; tegulre brownish ; face, 

 cheeks, thorax and legs more or less clothed with silvery pile ; apical 

 margins of abdominal segments 1-4 also with silvery pile. Length 

 4|7 mm. 



$ . — Very much like the 9 hut differs in being slightly smaller, 

 the posterior face of metathorax is transversely wrinkled and the 

 second submarginal cell is sub- angular beneath 3-3$ mm.

Form robust; head broader than the thorax; mandibles emargin- 

 ate on outer edge, their apex simple and their inner margin not den- 

 tate; antennae tolerably stout; eyes converging towards the vertex, 

 along their inner margins there extend ledge-like swellings which are 

 strongest in the middle mid are connected to each other by a transverse 

 swelling which extends aeross the front above the middle, below the 

 transverse swelling there are two longitudinal impressions, evidently 

 for the reception of thescape ; anterior ocellus round unit regular and 

 lies far before the two posteriors which are quite flat, longish, placed 

 close to each other and are generally indistinct; the collar is transverse, 

 straight and is not, or only in a very slight degree, depressed beneath the 

 level of the dorsulum ; marginal cell broadly truncate and with an appen- 

 diculation ; three submarginals, the first of which is about as great 

 as the two others united, the second trapezoidal or, if the first and 

 second transverse cubital veins are very approximate to each other 

 subtriangular, and receives both recurrent nervures, the third placed 

 obliquely ; in the hind wings the cubital vein originates a little be-
