HYMENOPTERA FROM SARAWAK. 71 



punctured ; the gastrocoeli narrow, deep, smooth, and shining. 

 Mesonotum rather strongly and closely punctured ; the scutellum 

 is as strongly, and more widely punctured ; its sides, under the 

 keels, strongly but not closely, punctured. The base of the 

 median segment is smooth ; the rest coarsely punctured, the apex 

 especially in the middle, closely reticulated ; the supramedian area 

 large, about as wide as long ; the sides at the base obliquely 

 narrowed, the middle straight, the apex is not clearly separated 

 from the posterior median by a keel. Pro- and mesopleurae 

 smooth ; the depression on the former stoutly striated ; the lower 

 half of the meso- is depressed and separated from the raised 

 upper half ; the meta- closely and strongly punctured. The 

 median segment is thickly covered with white hair.) 



Joppini Zonojoppa, gen. now 



Antennae short, distinctly dilated and compressed between 

 the middle and the apex; the dilated joints hollowed laterally. 

 Wings violaceous throughout ; theareolet is narrowed at the top, 

 the transverse cubital nervures almost uniting there; the trans verse 

 basal nervure interstitial. Scutellum roundly convex ; not raised 

 above the level of the mesonotum, its sides stoutly keeled. Areola 

 widely separated from the base of the segment, rounded and nar- 

 rowed behind, the basal half deeply hollowed, the lateral basal 

 areae clearly separated. Clypeus broadly rounded at the apex, 

 the labrum hidden. Legs short; the apex of the hinder femora 

 not extending beyond the apex of the third segment. The abdom- 

 inal segments do not project much laterally at the apex ; the 

 second and third segments are longitudinally striated at the base, 

 the last (seventh) segment is well developed ; its cerci are much 

 longer than usual. 



The thorax is shorter than the basal three segments of the 

 abdomen ; the middle of the mesonotum is raised and separated in 

 front ; the post-scutellum is shortly striated and depressed lateral- 

 ly ; the apical three areae on the median segment are closely defin- 

 ed, as is also the spiracular area ; the sides of the mesonotum are 

 bordered by a wide deep furrow ; there is a short stump of a ner- 

 vure on the disco-cubital nervure. 



The characteristic features of this genus are the violaceous 

 wings, the stoutly keeled scutellum, and the excavated areola.
