112 Knab — New Spirit* of Anisopidse from Tropical America. 



its whole length. Tlie costal cell is entirely and uniformly brown. There 

 is a large dark brown spot at the apex of the marginal cell and another 

 at its middle, both extending over diffusedly into the snbmarginal cell; 

 base of marginal cell clear. The veins limiting outwardly the basal and 

 discal cells enclosed in deep brown spots. A narrow, dark spot crosses 

 the first posterior cell obliquely below the apical spot of the marginal 

 cell; another similar spot crosses the second and third posterior cells 

 farther out, about at their middle. At the tip of the wing, independent 

 of all these spots, is a broad brown area, sharply and darkly limited in- 

 wardly on the submarginal and first posterior cells, becoming paler ami 

 indistinct outwardly and posteriorly. Lower branch of the fifth vein 

 margined with brown beyond the furcation. Ilalteres pale. 



Legs ochreous yellow marked with brownish black. Anterior legs with 

 the femora and tibife yellow, the tarsi with the tip of the first and all of the 

 succeeding joints infuscated. Middleand hind femora yellow at base, dark 

 beyond, a yellow ring beforeapex. Middle tibiae yellow, with an indistinct 

 dark ring at base and apex. Hind tibia? with distinct ami broader dark 

 basal and apical rings. Middle and hind tarsi with apices of first and 

 second joints dark, the last three joints strongly infuscated. 



Length: body, about <i mm.; wing, 5.5 mm.

 epiphytic bromeliads by C. Picado; one male and one female.

In the female the mouth-parts and palpi are darker. The mesonotum 

 shows a narrow yellow longitudinal line medianly and outwardly from 

 this a broad gray longitudinal stripe, another gray stripe at the lateral 

 margin. The mesonotum might also be described as gray with dark 

 longitudinal stripes, the middle one divided by a fine yellow line. The 

 discrepancy in the thoracic pattern of the two specimens is attributable 

 either to difference in age or to the condition of the specimens, these 

 having been preserved in fluid. The wing pattern in the female is more 

 distinct and the markings slightly broader. The species differs obviously 

 from all of the described ones in tin' wing pattern and the coloration of 

 the legs. 



Anisopus infuinatus sp. nov. 



Female. — Form rather robust. Head black. Mouth-parts and palpi 

 yellowish brown. Antenna? with the scape yellowish brown, the flagellum 

 black, the last joint pale yellow. Mesonotum very deep brown, an ill- 

 defined, rich brown, double, median longitudinal stripe. Scutellum 

 blackish. Postnotum yellowish brown. Pleura' deep brown, coxse 

 brownish black. Abdomen dull black, the first segment with an indis- 

 tinct pale brown blotch above and at the sides beneath. 



Wing deep brown, darkest along costa and towards apex, becoming 

 paler posteriorly. The stigmatal mark at the apices of the subcostal and 

 marginal cells rather ill-defined and divided by an indistinct paler spot. 

 A large pale spot crosses the submarginal cell and extends into the first 

 posterior cell, its base resting against the tip of the second vein. Another
