ICHNEUMONID GENERA LABIUM AND PtECILOCllYPTUS. 15 



lateral lobe.s and the scutellum sparsely punctured ; niesopleura? 

 antero-ventrally closely and rather strongly punctured, smoother 

 elsewhere; the epimeral sulcus coarsely crenulate throughout. 

 Median segment with the basal area and areola confluent ; areola 

 smooth, with a few punctures, posteriorly rugulose ; petiolar area 

 separated, transversely rugose, as also are the adjacent arece; ex- 

 ternal area smooth, very bluntly raised at the external apical 

 angle ; dentiparal area coarsely rugulose, with a small tootli at the 

 external apical angle ; spiracular area coarsely punctured ante- 

 riorly, rugose posteriorly ; pleural and juxta-coxal arese strongly 

 striate, with a few punctures between the striae. Hind coxaB 

 externally coarsely, hind femora much more closely and finely 

 punctured. Second abscissa (text-fig. 7, a) of the radius barely 

 longer than the second transverse cubital nervure ; the distance 

 between the recurrent nervure and the second transverse cubital 

 nervure more than half of the length of the latter nervure. 

 Petiole without a tooth between the base and spiracles, the latter 

 very prominent ; a carina beginning near the base aiid almost 

 reaching the apex, the central raised area strongly marked, 

 bearing throughout its length two parallel grooves.

Distinct in the strong sculpture, also in the black colour of 

 the thorax, petiole, and hind femora.

Long. 9 mm. 



5 . Mandibles (text-fig. 6, cZ) obscurely bid en tate, blunt, the second 

 tooth indicated by an external sulcus; cly pens and face sparsely 

 punctured, the line of division between them ^listinct, but not 

 strong. Antennae 36-jointed, the third and fourth joints sub- 

 equal, the third seen in profile slightly shorter than the fourth. 

 Mesonotum smooth, with scattered punctures, the notauli rather 

 long; propleur^iB strongly crenulate in front; mesopleura^ shining, 

 closely and very finely punctured on the lower half ; epimera,! 

 sulcus crenulate throughout, the lower crenulations more strongly 

 developed than usual. Median segment with the apical carina 

 of the basal area interrupted in the middle ; areola smooth, 

 slightly rugulose at the sides ; external area smooth ; dentiparal 

 area rugulose ; spiracular area coarsely punctured anteriorly, 

 rugulose posteriorly ; pleural area striate-i'ugulose, separated from 

 the juxta coxal area by a carina reaching to one-half, the latter
