614 NEW SPECIES OF BRACON1D.K. 



a narrow inner red orbital line, joins a wider postorbital line; the sur- 

 face in front of the ocelli impressed, with a longitudinal grooved line 

 extending from the front ocellus to the base of the antenna? ; base of 

 mandibles reddish ; antenna- long, 49-jointed, the scape not as long as 

 the breadth between the eyes, obliquely truncate at apex, the edges 

 sharp and outwardly slightly dilated; thorax smooth, polished, the 

 parapsides obliterated ; there is a small red spot on the middle and an- 

 other at posterior angles of the propleura, wanting, however, in the 

 male; metathorax smooth, polished, the sides covered with long hairs; 

 the venation of the wings normal, the second submarginal cell longer 

 than the first, the first transverse cubital nervure slightly oblique ; the 

 abdomen is all very coarsely rugose with coarse irregularly raised lines, 

 having more or less of a longitudinal direction ; the plate of the 1st 

 segment is narrowed at base, rugose, separated at sides by a deep lon- 

 gitudinal groove from a keel on each side, extending from base to apex 

 of the segment, this keel itself being separated from the lateral margins 

 of the segment by a deep groove; the second segment has a long tri- 

 angular shield medially, and on either side of it about midway between 

 it and the lateral margins another much narrower shield or keel ; all 

 the other segments are irregularly longitudinally rugose, the apical mar- 

 gins of which are more or less rimmed. 



The male measures but 7'" 1 " in length, and differs from the female as 

 follows: The head is entirely black, without the red orbital lines; 

 mandibles wholly black; antenme 46-jointed instead of 49-jointed; the 

 pleura- are not spotted; the metathorax almost entirely black ; while 

 the sculpture of the abdomen is not quite so coarse as in the female, 

 the two apical segments being perfectly smooth. 



Habitat— Bosque County, Texas. 



Described from five females and one male in the Belfrage collection 



from Texas. 

 The peculiar rugosity of the abdomen at once separates this species 



from all others in our fauna. 



Bracon atripectus n. sp. 



Female.— Length S'»™ ; ovipositor 8 mm . In stature and general appear- 

 ance very similar to B. orbitalis Cr., only the upper portion of the 

 mesothorax, propleura, small triangular piece of mesopleura, scutellum, 

 a broad dorsal line on metathorax and the abdomen are sanguineous; 

 the margins of the scutellum and the rest of the insect black. The 

 wings have a whitish spot behind the upper angle of the 1st cubital 

 cell, extending as a slight streak into the lower outer angle of the 1st 

 submarginal cell. The 1st abdominal segment is sculptured as in B. 

 orbitalis, but the triangular shield at base of the 2d segment is extended 

 posteriorly into a narrow keel to near the apical margin, the tip not, 

 however, separated from the surrounding surface; broad oblique de- 

 pressions extending from the base of the shield make the basal angles
