the middle but quickly appearing- toward the side; side of the median 

 seo'niciit ohiiciuely aciculate, more coarsely so anteriorly, the acicula- 

 tions continued onto tlie metapleura; the .sides are also coarsely punc- 

 tured and with quite a thick clothing of long hairs; portion of meso- 

 pleuron next below the tegula rather coarsely, nearl}' horizontally acicu- 

 late; portion 1)ehind the prothoracic lobe very finely, almost vertically 

 aciculate; the area next posterior to this with a faint trace of acicula- 

 tion, the grooves running obliquely downward and forward; lower 

 part of mesopleuron to the coxa? both minutely, closely, and also 

 coarsely, more sparsely punctured; the whole mesopleuron covered 

 with quite long hair; metapleuron everywhere more or less finely, 

 obliquely aciculate, least evident above the coxa^; coarsely punctured 

 and with long hairs; mesosternum with coarse punctures and long 

 black hairs; petiole black, shorter than the posterior coxa?, straight, 

 with rather tine punctures and medium long hairs. 



Alxlonieii, — High, rising nearly verticalh" from the petiole, broad, 

 ovate, most pointed behind; above; slightly sericeous in certain lights, 

 w^ith scattered punctures, mostly small, except on the last two seg- 

 ments, where they are coarser and closer together; terminal plate 

 rather narrow, its posterior margin rounded oval in outline; beneath; 

 first ventral plate smooth, glistening; ventral surface in general some- 

 what sericeous, with scattered fine and coarser punctures, mostly on 

 the sides and toward the hinder margins of the plates; second and 

 third plates broadl}^ slightl}^ emarginate behind; fourth with a few 

 short hairs at the sides; fifth with more hairs, narrower from side to 

 side, its hinder margin with a broad, shallow notch; sixth with its 

 sides rolled upward, showing from above, laterally quite compressed, 

 almost forming an edge along the median line on the hinder four-tifths 

 of its length; thickly, quite coarsely punctured, and with numerous, 

 long, stout hairs. 



Wings. — Uniformly fuliginous, a little lighter along the outer row 

 of cells, darker just beyond this, then lighter to the margin; with a 

 very faint, violet reflection; fore wings; radial cell bluntly rounded at 

 the tip, scarcely extending bej^ond the third cu])ital; second cubital 

 cell high, narrow, about equally wide top and l)ottom, the first trans- 

 verse cubital vein bending into the tirst cul)ital cell somewhat; hind 

 wing; transverse median vein making less than a right angle with the 

 median, the discoidal veins ))eing almost interstitial at this point; a 

 faint trace only of the cubital vein beyond the transverse cubital; teg- 

 uhe black, sericeous in front, smooth behind, and dull ferruginous 

 there in some lights; with a few short hairs. 



Leys. — Coxa^ black, sericeous in some lights, with numerous coarse 

 punctures and long hairs; trochanters similar, the hairs less abundant; 

 femora l)lack, the front pair stoutest; all slightly sericeous in places, 

 glistening, with scattered, coarse punctures and hairs of medium size;
