(Continuation.) 



Irlinpiimonini. 



Stirexephanes, gen. n. 

 Scutellutn margined laterally by a distinct keel, 

 which becomes weakei: roand the apex, metanotum 

 regularly areolated, the areola longer than wide, 

 transverse at the apex, rounded at the base. Apex 

 of clypeus transverse; labrum prominent, rounded. 

 Abdomen with 8 segments, the last distinct, half 

 the length of tbe penultimate, the 1st long, slender 

 smooth and shining, becoming gradually shghtly 

 widened trom the middle to the apex ; the post-jDetiole 

 not clearly separated. Gastracoeh indistinct. Ventral 

 keel extending to tbe apes; isf the 5th segment. Ovi- 

 positor broad, projecting, the projecting part as long 

 as the apical 2 segments united. Mandibles with a 

 long, sharp -pointed upper and a short sub-apical 

 tooth. The areolet is 5 angled and receives the recur- 

 rent nervure in the middle, recurrent aervare broken 

 by a stump, but not the disco-cubital; transverse 

 median nervure interstitial. 



Ths apices of the tarsal joints arc spinose. Antennae 

 thickened towards the apex. The abdomen becomes 

 gradually narrowed to a sharp pomt from the base 

 of the 5th segment. 



AUied to ExepJianes, having hke it 8 abdominal 

 segments and a projecting ovipositor. It rnay be known 

 from it by the keeled scutellum, and by the smooth, 

 slender abdominal petiole. 



Stirexephanes melanarius, sp. n. 

 Black, the palpi white, mandibles with a red 

 band before the small tooth ; the 4 anterior trochanters 

 white , the anterior femora and tibiae and the base 

 of the middle tibiae rufotestaceous, the fore femora 

 blackened towards the base; ^ràigs hyaline, tinged 

 with fuscous violaceous, the nervures and stigma 

 black. $. 



Length 12 mm. 

 Matang, June. 



Face broadly in the centre somewhat coarsely 

 punctured, this part bordered by obhque striae lea- 

 vmg an almost smooth triangular sj)ace on the sides, 

 the narrowed end above. Vertex and front closely 

 punctured; the oeciiDut smooth and more shiiüng. 

 Mesonotum closely punctured; the scutellum more 

 sparsely, but more strongly punctured. Basal areae 

 of metanotum weakly punctured, the apical lateral 

 areae more strongly than the basal; the 3 posterior 

 more strongly transversely striated; the spiracular 

 area at the base weakly, at the apex more strongly 

 obUquely striated. Propleurae with a strong curved 

 obhque keel near the base, smooth, except for some 

 longitudinal striae in the middle of the apex, the central 

 striae longer than the others. Face and metathorax 

 densely covered mth short white pubescence. 



Caenojoppa maciiliceps, sp. n. 



Black, the face except for a mark in the centre, 

 wliich becomes gradually, shghtly widened to shortly 

 below the middle, then broadly, roundly widened, 

 with the lo'^A'er outer edges projecting round for a 

 short distance, -the suture over the cly^DCus, thefroht 

 broadly in the centre, the yellow, outer bordering Une 

 bemg of equal width and extendmg to the lower 

 oceUi, a hne on the outer orbits, the upper half narrowed 

 and with an irregular outer edge, a short curved 

 mark on the apex of the pronotum in the centre, a 

 short Ime touching the tegulae, the greater part 

 of the apical half of the propleurae, the tegulae, 

 upper part of scutellum except the basal slope, the 

 apex of metanotum, except for a conical spot in the 

 middle below, the top roundly narrowed and extended 

 to the areola, tubercles, almost the lower third of the 

 mesoiDleurae, the mark projecting slightly at the 

 apex above, a longish triangular spot on the pleurae 

 below the hind «ings and continued down the divi- 

 ding suture as a narrow Une, a broad Hne on the 

 iuetapleurae extending from the keel to near the 

 middle, its base bemg blvmtly rounded, the apex 

 projecting shghtly below, the basal fourth of the 

 2nd abdominal segment, a line, narrower, but with the 

 outer edges dilated on the base of the 3d, the apices 

 of the 4th to 5th very narrowly, that of the 6th a 

 Uttle more mdely, the 7th enthely above and its sides 

 broadly and the 2nd and following ventral segments, 

 pale yellow. Legs pale yellow, the 4 front femora 

 and tibiae behind the hind coxae below, at the base 

 laterally and the basal third above, the inner side 

 on the basal two thirds, the apical joint of the hind 

 trochanters, the outer two-thirds of the apex of the 

 hind femora, the imier haK of the hind tibiae except 

 below, the apices of the basal 3 joints of the hind 

 tarsi and the apical 2 entirely, black. The apex of 

 the 5th antennal joint, the 6th to 14th and the base 

 of the 15th, white. Wings hyaline,, the stigma and 

 nervures black, the areolea 5-angled, narrowed in 

 front, the recurrent nervure received in its centre; 

 the disco-cubital nervure with a distinct stump. $. 



Length 10 mm. 



Head and abdomen shining, the thorax opaque. 

 Face weakly punctured. Propleurae somewhat strongly 

 striated, the mesopileurae more finely striated, more or 

 less punctured below, the apex smooth. Metapleurae 

 closely, distmctly punctured, more or less striated 

 below. The scuteUum is more strongly punctured 

 than the mesonotum, its sides keeled, the apex 

 transverse. Areola broadly rounded behind, open in 

 front; the only keels are 2 transverse ones ; the apical 

 projects backwards in the centré, (to be continued.)
