 thorax truncate at apex, straight laterally for one-fourth of the length, 

 a little narrowed but parallel for half the length, and broadening for 

 the remaining fourth but still straight laterally and with the base 

 one-fourth wider than the apex, declivity quite perpendicular, whole 

 surface covered with deep, elongate, narrow and closely set foveae, 

 basal part with a distinct transverse sulcus above the upper margin 

 of the declivity ; abdomen sessile, pyriform, segments finely sha- 

 greened, second one w r ith two round patches placed nearer to the 

 base than to the apex, third and fourth with two sub-quadrate patches 

 in a line with those on the second segment, apical part of the ultimate 

 segment fringed with thick, long, white hairs ; ventral carina of the

 .is covered with rough, confluent punctures ; abdomen pyriform, 

 second segment closely and finely punctured and having two median 

 whitish patches equidistant from outer sides and apical and basal 

 margins, third segment clothed with a band of white pubescence,
