the anterior margin, these teeth being about as far apart as the pedicellum 

 is wide ; scape nearly as long as the pedicellum and first two joints of 

 the flagellum combined ; first joint of the flagellum as long as the second; 

 upper part of front, vertex and occiput with less cop.spiciious whitish 

 pubescence than on the middle third of the face; dorsulum with a more or 

 less distinct margin of appressed dirty white pubescence, somewhat tinted 

 with ochreous, this margin interrupted on the anterior edge of the 

 dorsulum, the interruption as wide as the scape is long ; on each side of 

 the interruption the pubescent margin is prolonged back on the dorsulum 

 at right angles to the anterior margin for a distance somewhat less than 

 the interruption cited above ; pronotum, pleura, except the lower half of 

 the mesopleura, which is nearly bare, posterior margin of scutellum and 

 postscutellum with appressed pubescence similar to that on the dorsulum, 

 but paler, more whitish; the scutellar spines are distinctly shorter than the 

 convexity of the scutellum ; metanotum uniformly dull, with an indistinct 

 median longitudinal rugulose impression ; sternum uniformly pubescent 

 like the superior half of the mesopleura, the pubescence of the sternum 

 almost white. 



Abdomen : The pubescence is rather rubbed off, but is nearly as 

 follows : Anterior face of basal segment with appressed pubescence of 

 much the same colour as the pale pubescence on the dorsulum, this pubes- 

 cent area connected by a broad band of concolorous pubescence, with the 

 apical band occupying the depressed portion of the segment, narrower 

 than the connecting band, but also concolorous, succeeding segments with 

 only the a])ical band, which is similar to the apical band of the first seg- 

 ment, the penultimate segment almost uniformly covered with appressed 

 pubescence, otherwise the abdomen is clothed vviih brownish pubescence 

 excepting the lunule and all of the venter but the apical segment; 

 pygidium rather flat, and with lateral margins. 



Almost entirely black ; flagellum brownish, mandibles ferruginous 

 except at extreme base and apex, where they are blackish ; legs blackish, 

 knees, apices of tibise and tarsi ferruginous. 



Two $ $ . Paratype differs as follows : The frontal keel prolonged 

 as a raised line higher than the middle of the front, and finally connecting 

 with the anterior ocellus by a smooth shining line; the median longitudinal 

 groove on the metanotum is here a distinct shallow chaniiel.
