BACUMA, gen. nov. 



Abdomen long, of uniform thickness to the penultimate segment, 

 with eight distinct segments ; the basal four longer than wide ; the 

 basal six closely, strongly rugosely punctured ; the seventh and 

 eighth segments large ; the seventh longer than the sixth. Eadial 

 cellule long, reaching to the apex; transverse median nervure inter- 

 stitial ; the recurrent nervure received in the first cubital cellule ; 

 second cubital cellule below twice longer than wide. Mesonotum 

 trilobate. A deep, obscurely crenulated furrow at the base of the 

 scutellum. Legs long and slender; the hind tibiae at least three 

 times longer than thick ; fore tarsi twice the length of the tibiae. 



There is a short, wider than long, smooth plate on the base of the 

 second abdominal segment ; the hypopygium is very large, broad ; it 

 commences at the base of the fifth segment. Occiput not margined. 

 Eyes large, parallel ; there is a distinct malar space. Calcaria 

 minute ; the claws are more prominent. Front excavated ; a raised, 

 furrowed keel down its centre. Antennal scape about four times 

 longer than wide, of equal thickness throughout ; the basal joints of 

 flagellum of equal length. Anal nervure not interstitial. 



In the table of Szepligeti (Gen. Insect. Braconidae, 11) this genus 

 would come in near Sijntomomelus and Cocloidcs, with neither of 

 which can it be confounded. 



Bacuma maculiventris, sp. nov. 

 Luteous, the apex of mandibles, antennae, middle of front broadly, 

 the greater part of vertex, the mesonotum, except for a large mark, 

 longer than broad, its sides at the base slightly prolonged, on the 

 apex in the middle, a mark on the basal joint of the hinder 

 trochanters below ; the hind femora except on the top and apex and 

 the hind tibiae and tarsi, four large marks on the venti'al surface, 

 cleft in the middle at the apex and the large cultriform hypopygium 

 black, the black continued broadly along the sides of the segment 

 behind. Wings dark fuscous ; the basal half of stigma orange- 

 yellow ; a cloud runs from the orange part of the stigma, obliquely 

 to the apex of the wing ; there is a hyaline cloud near the apex of 

 the median and submedian cellules, a small one at the base of the 

 hind wings, and an oval one below the base of the cubitus. Face 

 rugose, covered with long fulvous hair ; the front and vertex shining. 

 Thorax smooth, shining ; there is an elongated tubercle on the base 

 of the metanotum. Middle of first abdominal segment stoutly.
