ON SOME NEW GENERA AND SPECIES OF HYMENO- 

 PTERA (ICHNEUMONID^, CHRYSIDID^, FOSSORES, 



AND AFIDM). 



By p. Cameron. 



ICHNEUMONID^. 

 (Continued from p. 111.) 



Habrojoppa, gen. nov. 



AntennsB dilated aud compressed beyond the middle ; the apex 

 attenuated. Eyes small, reaching to the middle of the face, the malar 

 space being large ; they are parallel on the inner side. Occiput mar- 

 gined. Clypeus not separated from the face by a suture. Labrum 

 hidden. Mandibles with two equal teeth on the apex. Mesonotum 

 reticulated, without furrows. Scutellura stoutly keeled laterally ; its 

 apex incised. Median segment reticulated; the basal and central 

 arete only are defined ; the sph-acles linear. Areolet much narrowed 

 at the top ; the transverse cubital nervures almost meeting there ; it 

 is angled below, and receives the recurrent nervure near the middle ; 

 the transverse median nervure is received shortly beyond the trans- 

 verse basal on the outer side. Legs normal ; the claws simple. Petiole 

 long and slender, dilated at the apex ; the spiracles are placed near 

 the apex of the basal fourth. Gastrocoeli large, deep. There are seven 

 segments ; the last three are smaller than the others, and form a sharp 

 point ; the ovipositor hidden ; the ventral fold only extends to the apex 

 of the second segment ; the last ventral segment is large, entire, 

 broadly rounded at the apex ; its base extends to the base of the 

 penultimate dorsal, and does not extend to the apex of the last dorsal ; 

 there are only six ventral segments in the female. The apex of the 

 hinder femora reaches to the base of the fourth segment. 



From Charitojoppa it may be known by its more slender 

 form, by the scutellum not being pyramidal, by the petiole being 

 more slender, and not broadly dilated at the apex. In the form 

 of the scutellum it more resembles Magrettia* but it wants the 

 coxal spine, the pronotum is not incised behind, and the second 

 and third segments are longitudinally striated ; the petiole is 

 more slender towards the apex, and longer, more as in Ichneumon 

 than as in Platyuri. 



Habrojoppa rufo-petiolata, sp. nov. 



Cserulea ; abdomine albo annulato, basi rufo ; pedibus rufis, tarsis 

 posticis nigris ; alis fusco-hyalinis. ? . Long. 12 mm. 



Hah. Khasia (coll. Kothney). 



Antenna black, the eighth to the thirteenth joints white, the 

 apical joints compressed, fuscous. Head shining, blue, the face and 



■''■ Magrettia, I find, is preoccupied in Orthoptera. I now propose the 

 name of Xenojoppa for it.
