Female genitalia, oblique lateral view, ov = ovipositor. differentiated. Halteres dark. Lower calypter smoky black, diverging away from the scutellum, contrasting with the milky white upper calypter.

. British journal of entomology and natural history. Natural history; Entomology. Figs 1-3. Catharosia pygnuiea. 1. Forewing of male. 2. Male genitalia, lateral view. 3. Female genitalia, oblique lateral view, ov = ovipositor. differentiated. Halteres dark. Lower calypter smoky black, diverging away from the scutellum, contrasting with the milky white upper calypter. Legs: Entirely black with moderately lengthened feinoral bristles, but tibiae with few rather weak bristles, none longer than width of the tibia. Wings (Fig. 1): Distinct blackish smudge in subcostal area beyond subcosta in front of cell r4 + 5. Wing tip beyond vein M milky white, foriTiing a conspicuous spot when viewed against a dark background. Remainder of wing membrane with a less conspicuous grey tint that becomes darker in cell r4 + 5 and in the basal subcostal area. Vein M sharply curved towards tip, joining vein R4 + 5 well before wing tip, leaving a long stalk subequal to length of crossvein m-cu. 1-2 bristles on node of vein R4 + 5. No subcostal spine. Costal breaks just distal to the humeral cross vein and immediately before junction of costal and subcostal veins. Abdomen: Tergites shining black, scarcely dusted, with general covering of short, decumbent black hairs. Rather weak marginal bristles present, most conspicuous on tergites 4 and 5. Syntergite 1+2 somewhat longer than tergite 3, with basal excavation weakly formed at the extreme base. Genitalia: Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Entomological and Natural History Society.
