The sculpture is charaetei'i^tio; the head is finely rug-ulose, sub- 

 opaque, with some elevated lines in front of the ocelli, and a delicate 

 carina extending from the front ocellus anteriorly- to between the 

 antenna?; the antennw are slig-htly thickened toward apex, the third 

 joint being- very long and cylindrical, about three times as long as the 

 scape and pedicel united; the large prothorax has a constriction pos- 

 teriorly and is longitudinally striated, with a smooth space on its disk 

 and at the lower lateral margins; the mesothorax is rugulose, the 

 pleura with some transverse ridges or carina?. The mesonotum has 

 two delicate parapsidal furrows, the middle lobe, except just in front 

 of the scutellum, being smooth and shining, the lateral loV^es being 

 finely, opaquely rugulose; the scutellum is opaque but not rugulose, 

 and has four fovea? across the base; the metathorax is long and rather 

 coarsel}^ reticulated with irregular elevated lines; the abdomen is

Manila. (Father Robert Brown.) This is one of the largest and 

 handsomest species 3'et discovered, and will be found to be parasitic 

 upon some large Rhyngotous insect belonging to the family Fulgo- 

 r!d^ or Memhracid^e. It shows some affinity with D. stantoni Ash- 

 uiead, recently described from the Philip})ines, but it is fully twice as 

 large, quite differently sculptured, and with different colored antennae 

 and legs.

 beneath and the middle and hind tarsi, ferruginous or rufous; the

 mandibles broad, coral red, 5-dentate; the scale of the abdominal 

 petiole is transverse, seen from the side twice higher than long, the 

 upper margin rounded with some spar.se, erect hairs; the gaster is
