Male. Antenna? i-eddi^:!!, t\vo Ijasal joints beset with lung, black hair; face brownish, 

 clothed with yellowish-brown pollen. Thorax blackish-brown, with a yellowish pubescence; 

 pleura? grayish-poUinose. Abdomen Ijlackish-brown, with narrow yellow bands, clothed 

 with a golden-yellow pubescence, along the incisin-es of the segments. Legs reddish-yellow, 

 tips of tarsi brownish. Wings : root hyaline, with pallid veins ; a brown cloud occupies 

 the proximal and anterior part of the wings, fdling the two basal, the marginal, the greater 

 portion of the first sulnnarginal, and the proximal half of the first posterior cells ; also inva- 

 ding the proximal ends of the discal and the fifth posterior cells ; anal aiigle and anal cell 

 also tinged with brown in the middle ; costal cell and stigma browni.sh-ferruginous ; second 

 submarginal cell grayish ; the remainder of the wing, between the ends of the third and 

 fifth veins, along the hind margin, including the larger portion of the discal cell, hyaline. 



Female. Head pale yellow, opaque ; front very broad, broader anteriorly than posteri- 

 orly ; eyes comparativel}' small ; a triangular space above the antenna; is destitute of pol- 

 len, and hence more shining ; below the antennre, down to the palpi, there is a convex, 

 trapezoid*! reddish-yellow, shining space, limited by deep grooves. Antenna? 3'ellbw, third 

 joint reddish. Palpi yellow, with short, black hairs. Proboscis extending but little beyond 

 the palpi, yellow, lips large. Cheeks clothed with a very soft, whitish pubescence. Thorax 

 somewhat reddish on the disc, with a faint trace of a longitudinal dark line, otherwise uni- 

 formly yellowish, densely clothed with appressed pale yellow, shining hairs. The abdom-

 uniformly yellowish, w'xih a dense, appressed, pale golden-yellow, shining pubescence. Ilal- 

 teres and legs yellow. Wings : a pale brown cloud of a rather indefinite outline occupies the 

 two basal, marginal and suljuuirginal cells, somewhat encroaching upon the base of the 

 first posterior, of the discal and slightly upon the fifth posterior cells ; the root of the wing 

 is hyaline ; the costal cells, the base of the marginal cell and the whole posterior half of 

 the wing are impure hyaline ; a slight brownish cloud in the axillary corner of the wing. 

 Sigma and its environs tinged with yellow. Base of the second submarginal cell rather, 

 acute ; no stump. All posterior cells open.

Obseroatlon. The proboscis of tliis species is vuuisually short for a Pangonia ; the basal 

 division of the third joint is stout, without any vestige of an angular projection ; the ( 9 ) 

 front is three times as broad as in the three preceding species ; the head is flattened, etc.^
