Descriptions of New Species of Parasitic Hyvienoptcra. 77 



and the sides of the others suffused with black ; the ventral surface 

 deep black ; wings fuscous, the basal third yellowish hyaline in both 

 wings, the yellow part becoming obliquely widened towards the 

 costa. $ . 



Length 13 mm. ; terebra 3 mm. 



Cape. 



Occiput, front and vertex sparsely covered W'ith longish black 

 hair ; the face and oral region more thickly with longer paler hair. 

 Thorax shining ; the median segment strongly, but not closely punc- 

 tured ; the furrow becomes gradually widened at the apex ; the 

 narrowed basal part is obscurely striated. Abdomen strongly, 

 closely, sharpl}^ longitudinally striated, the striae becoming stronger 

 towards the apex ; the furrows deep, crenulated ; the longitudinal 

 furrows narrow, not very distinct ; the segments densely covered 

 with pale pubescence ; the striae in places appear of a golden hue. 

 The furrows bordering the area on the second segment are obscurely 

 striated. 



The wings in this species are more ample than in nigriccps. 



DOBYCTINM. 

 LATANx\, gen. nov. 



Cheeks stoutly margined. Face and malar space deeply exca- 

 vated. Front depressed in the centre. Transverse basal nervure 

 interstitial ; the recurrent received in the first cubital cellule. 

 Abdomen as in Ipiliiaulax, with a smooth area on the second seg- 

 ment. Antennae issuing from broad raised tubercles, bordered on 

 the outer side by a projecting rounded plate ; third joint of antennae 

 longer than the fourth. Eadial cellule long, reaching to the apex of 

 the wing ; the second cubital cellule twice longer than wide. Meta- 

 tarsus shorter than the following two joints united. 



If it were not for the margined cheeks this genus might be con- 

 sidered an Iphia^ilax. The first abscissa of the radius is not longer 

 than the thickness of the middle of the stigma, much shorter than 

 the second ; the basal two joints of the fore tarsi are as long as the 

 tibiae; the fifth not double their length. Penultimate abdominal 

 segment short ; the hypopygium long. The trophi form a large 

 mass. 



In the arrangement of Sz^pligeti this genus would come in near 

 Gymnohracon and OsmopMla.
