Appendages ferru- ginous (Text-tig. 49). Genital organs of second segment, Text-fig. 50.

Abd. 2b' + 3, hdw. 22, pt. 3 mm. 9 . No certainty exists about the identity of this female with the typical males ; but since the thoracic pattern is very much the, same, the identification here suggested seems probable. In this female the anterior, dorsally directed branch of the obscure baud on second lateral suture is longer and broader, the same colour at latero-ventral border of metepimeron is more developed than in the male figured (Plate IX, tig. 3). The markings of the abdomen seem somewhat different. FIG. 51. Mesogomphus elpidius, $ . Kapiri. ventral side view. Terminal segments, (in better condition). Abdomen reddish ochreous, a blackish lateral longitudinal line on segments 2-6, dilated dorsally at the anterior carina, and narrowly interrupted at the anterior margin and contracted in the middle of each segment; segment 7 ochreous in basal, dark ferruginous in apical half; 8-10 dark ferruginous. Only a slight indication of the foliaceous dilations on segments 8-9. Groove on ventral plate 9 much smaller than in Hagetii; roughly triangular in outline; vulvar scale smaller, with broader terminal excision (Text-fig. 51). Appendages very fine and pointed, light ochreous. Yellow line on costal vein narrower than in male. Pterostigma as in male. Abd. 32, hdw. 28, pt. 3'5 mm. MESOGOMPHUS COGNATUS (Eambur, 1842)
