ADULT FEMALE. — Very small species. Head: Proboscis dark scaled, long, 

 broadened apically; palpi very short, dark scaled. Occiput shingled with dark 

 broad appressed scales having a bronzy sheen, margined anteriorly and laterally 

 with broad iridescent pale-blue scales. Thorax: Integument of scutum light 

 brown, darker medianly, and with a darkly pigmented spot laterally just anteri- 

 or to wing base; vestiture of scutum consisting of dark-brown lanceolate scales 

 on dorsal surface and a row of broad pale-blup iridescent scales on lateral dark 

 spot. Patches of similar iridescent scales present on anterior pronotal lobe, the 

 bases of the coxae and the midportion of the sternopleura. A single spiracular 

 bristle present; postspiracular bristles absent. Abdomeji: Tergites dark-brown 

 scaled with a metallic luster; segments III, V, and VI each with a rather large 

 lateral apical patch of pale-blue iridescent scales, and lateral margin of segment 

 II often similarly marked; sternites pale-yellow scaled. Eighth segment blunt, 

 largely retracted within the seventh. Legs: Fore and middle legs entirely dark 

 scaled; hind leg dark scaled except for tarsal segments 4 and 5 and apex of 

 segment 3, which are white scaled (Fig. 51A). Wing: Scales rather broad, 

 dark-brown except for a short row of iridescent pale-blue scales on base of vein 

 5 and another near base of vein 1; second marginal cell much shorter than its 

 petiole. 



ADULT MALE. — Coloration and antennae similar to that of female. TERML 

 NALIA (Fig. 51). Ninth tergite (IX-T) broad, deeply emarginate anteriorly, 

 strongly convex and extending considerably dorsad of underlying structures; 

 lobes (IXT-L) pointed, a little longer than basal width, separated by about 

 twice the width of one lobe. (These prominent, triangular structures do not 

 seem to be true lobes of the ninth tergite. They are probably the tips of either 

 an enlarged tenth tergite or the dorsal arms of the tenth sternite. In a lateral 

 view this pair of strong, rib-like structures can be seen to curve dorsally and 

 fuse with the apical margin of the ninth tergite.) Tenth sternite vestigial, not 

 supporting the anal membrane (A-M). Phallosome (Ph) consisting of two 

 heavily sclerotized plates, open ventrally, closed dorsally; each plate with three 

 large thorn-like dorsal projections and three very large sickle-shaped serrated 

 ventro-lateral processes directed ventro-anteriorly. Claspette absent. Basistyle 

 (Bs) about four-fifths as broad as long, pyriform, rounded apically, clothed 

 with long setae; basal lobe (B-L) a rounded thickened area on the inner face 

 of the basistyle, crowned with numerous stout setae; apical lobe absent. Disti- 

 style (Ds) greatly swollen beyond base, twice as long as broad, half as long as 

 basistyle; apex bluntly rounded, bearing 15 to 20 short broad heavily sclero- 

 tized spines. 



LARVA (Fig. 52). — Head slightly longer than broad, darkly pigmented 

 except in ocular region. Antenna about one-fourth as long as the head, with a 

 few coarse spines; antennal tuft represented by a small single hair inserted
