272 SUPPLEMENT. 



Exoprosopa filia (p. 86). 



To the locality given, add : — Mexico, San Bias in Jalisco {Schumann). 



Two specimens, which agree in all respects with Osten Sacken's description, save as 

 regards the terminal abdominal segments. The third and following segments are 

 clothed for the most part with whitish tomentum, somewhat intermixed with black 

 in front or in the middle. The proboscis seems to be a little longer than he described, 

 though far shorter than in E. rostrifera. 



9 (a). Exoprosopa brevirostris, sp. n. 



S . Third joint of the antennae elongate-conical, the style equal to about three-fifths of its length : face 

 prominent. First posterior cell coarctate ; wings brown anteriorly and with clouds upon the cross-veins. 

 Structure of the head nearly as in E. limbipennis, the proboscis barely projecting beyond the oral margin, 

 the style of the anrennse perhaps a little shorter. Pront and face clothed with black and rufous 

 tomentum : lower part of the front and ground-colour of the face reddish-yellow. Hair of the front 

 and sides of the thorax yellowish. Scutellum red. Abdomen black-tome ntose, the second segment with 

 a yellowish-white band, narrower in the middle ; fourth segment with a whitish spot on each side, and 

 the seventh segment with white hairs; the segments all have some rufous or yellowish tomentum on the 

 posterior margin. Wings brown in front, the brown margin running from the base of the fourth 

 posterior cell, where it coalesces with the dark brown clouds on the base of this and the third posterior 

 cell, to the tip of the first vein ; base of the anal cell brown ; first posterior cell open. Legs wholly 

 black. Length 12-14 millim. 



Hab. Mexico, Santiago Iscuintla and Guadalajara in Jalisco (Schumann). 

 Two specimens. 



9 (b). Exoprosopa brevistylata, sp. n. 



J . Allied to E. brevirostris, but differing from it in having the third joint of the antennse much elongated, 

 the style short and not one-third the length of the joint. The wings are less hyaline posteriorly, the 

 brown in front paler in tint, and its limits indistinct, more so than in E. limbipennis. The second basal 

 and the discal cells are not clouded throughout with brown, but are subhyaline, like the posterior part of 

 the wings ; the clouds on the cross-veins, though indicated as in E. brevirostris, are, except those at the 

 base of the third submarginal and posterior cells, indistinct; the first posterior cell is narrowed. 

 Abdomen with a complete yellowish-white cross-band on the fourth segment, and with similarly coloured 

 spots on the sides of the second, fourth, and fifth segments. Length 15 millim. 



Hab. Mexico, Acapulco in Guerrero (H. H. Smith). 



One specimen. The species is at once distinguished from any other of this "roup 

 by the very long third antennal joint and short style. The front tibiee, as in E. brevi- 

 rostris, are without spinules. A second example, sent with the other, has a white spot 

 on the sides of the second, third, fourth, and perhaps the fifth, segments. The abdomen 

 has the elongated form of that of E. limbipennis, &c. 



Exoprosopa socia (p. 87). 



To the locality given, add : — Mexico, Amula in Guerrero (H. H. Smith). 



A single specimen, which, though somewhat injured, agrees well with Osten 

 Sacken's description. There is a hyaline spot on the inner marginal cell.
