Head seen from above: Fig. 28, OOD:POD:OCD approximately 10:6:12, width of postocellus relatively 5, vertex and upper frons nearly flattened, somewhat similar to the state of Crossocerus (Cuphopterus), ocellar area and postocellar area slightly raised and outer side of each postocellus gently depressed, frontal impressions distinctly outlined and large (Fig. 28), frontal furrow broad and deep, especially marked at the verge of upper frons, head seen in front: Fig. 29, antennái socket contiguous with the eyes, clypeus as in the figure, mandible in frontal view: Fig. 31 and in lateral view as in Fig. 30, with outer side slightly excavated at a medial third ; head seen in profile : Fig. 30, occipital carina approaching below the hypostomial carina, but not reaching there; antennái joint 1 (scape) about twice as long as the minimum interocular distance at base of clypeus, joint 2 in dorsal view approximately 2.7 times, in lateral view thrice as long as broad at apex, joint 4 about 1.3 times, 6 and 7 as long as broad at each apex, ultimate joint normal, • fringe of hair as lorg as the width of the respective segment, but apically slightly shorter. Collar of pronotum comparatively broad, with latero-anterior angles rounded, without medial impression or incision, on mesopleuron epicnemial area distinctly margined with lamellate carinae, on inner margin the carina much higher, turned posteriorly along the longitudinal suture of the area and soon vanished, acetabular carina absent, area dorsalis on propodeum: Fig. 32, posterior inclination medially narrowly furrowed above and acutely carinated behind, without the lateral carinae separating it from the sides of the segment, end tergite : Fig. 33, medially with a short longitudinal impression, fore femur seen from behind: Fig. 34, the apex of the tooth rounded, lamellate and trasparent yellow; in fore wing transverse radial vein forming a right angle with the radial vein. Vertex very finely and sparsely punctured, punctures on occiput slightly larger and close, on upper frons much larger and closer, with interspaces as large as the punctures, not confluent into rugae or striae, on anterior frons punctures smaller and closer, but not well visible due to appressed pubescence, punctures on mesonotum as on upper frons, but on central area sparser, with interspaces 2—3 times as large as the points, on mesopleuron much finer and sparser, area dorsalis on propodeum at base coarsely foveolate, on the disc smooth, but in certain light very fine close oblique striae can be seen, posterior inclination medilly above smooth, with medium-sized punctures scattered, posteriorly and laterally transversely striate, the striae fine and close above and coarse below, sides of the segment on posterior half longitudinally (slightly obliquely) finely and closely striate and on anterior half smooth and polished ; abdominal tergites very minutely and sparsely punctured, punctures on the last tergite medium-sized and somewhat closer, sternite 2 sparsely scattered with punctures, punctures fine, but somewhat larger than on tergites. 9 . Length 9.5—12.0 mm. Coloration generally as in rf, but the mark on clypeus varied in extent, sometimes separated into two spots, with various intergradations between the extremities, yellow maculae on mesopleuron much less developed than in rf, epicnemial area ar.d mesosternum always wholly black, marks on prepectus (s. episternum before the oblique suture, excluding epicnemial area) and epimeron markedly varied in extension, sometimes only a small spot on prepectus only, marks on abdomen also variable, in the melanic specimens tergite 1 completely immaculate, marks on 2 and 3 broadly separated and the band on 4 medially notched, in the bright-coloured specimens lateral marks on tergites 1 and 2 approaching very closely together, and on 3 turned into a band ; on ventral sides except the ferruginous apical margin of each segment wholly black, with
