ON PARASITIC HYMENOPTERA. 101 



Head smooth, the upper part sparsely, the lower thickly covered with white 

 pile. Hind ocelli separated from each other by double the distance they are 

 from the eyes -, they are placed slightly behind the hinder edge of the eyes. 

 Temples about one-half the length of the eyes, roundly narrowed behind. 

 Malar space about as lon^ as the pedicle of the antennas. Thorax alutaceous, 

 •opaque, covered with a white down ; the metanotum almost rugose, a smooth 

 shining line down its centre. The lower part of the propleura? is shining, 

 sparsely punctured and is separated from the upper part by a narrow furrow. 

 The 3rd antennal joint distinctly shorter than the 4th ; it is twice the length of 

 the pedicle, the scape is not twice longer than wide. The 4 front tibia? and tarsi 

 are for the greater part white ; there is a narrow white line at the base of the 

 tibia? and a wider one on the base of the metatarsus. 



The amount of red colour on the abdomen varies; the $ appears to want 

 the white mark on the metatarsus. Probably the quantity of white colour on 

 the 4 anterior tibia? and tarsi varies. The stigma is fuscous ; the posterior 

 discoidal cellule is shorter than the anterior. The punctuation on the thorax 

 is sparse, but distinct. 



Braconid.e. 



Mic rogas terince. 



Dapsilotoma, gen. nov. 



Antenna? 36-jointed. Radial cellule long, narrow, lanceolate, extending to 



the apex ; areolet triangular, the basal nervure roundly curved, the apical 



straight, oblique ; transverse median nervure received distinctly beyond the 



transverse basal ; the recurrent nervure in the 1st cubital cellule clearly 



•distant from the first transverse cubital. Basal abscissa of cubitus distinct. 



Eyes hairy ; there is a distinct malar space. Clypeus separated from the face 



by a narrow furrow. Median segment reticulated, keeled down the middle. 



Basal two abdominal segments longer than the others ; the 1st longer than 



wide, longer than the 2nd, which is square. 



There is a crenulated furrow on the mesopleura? ; the legs are stout, the 

 spurs short ; the stigma large, broad ; the radius issues from its middle ; there 

 as a distinct cubitus and radius in the hind wings. Ovipositor short, its sheaths 

 broad. 



This genus should be readily known by the large number of joints in 

 the antenna?. 28 is the largest number hitherto recorded, namely in the 

 Brazilian genus Oligoneurus, the other genera having from 14 to 21 joints. The 

 affinities of my genus are with Microgaster and JlicropUtis. 

 Dapsilotoma testaceipes, sp. nov. 

 Black, the flagellum of antenna? rufo-fuscous ; the legs rufo-testaceous ; 

 the coxaa black ; wings hyaline ; the costa and apical two-thirds of stigma 

 black, the base of stigma white, the nervures testaceous. Mandibles and oral 

 •region rufous ; the palpi testaceous. Head and thorax obscurely, minutely 

 punctured, covered with a white down. Metanotum strongly reticulated ; 

 <the upper side of the pleura? obliquely, closely striated. Abdomen smooth,
