370 Miss G. llicaiclo on the Tabaiiiiue 



tibiae and tlie basal joint of the middle tarsi whitish. The 

 wings may be more accurately described as having the fore 

 border brown as far as the apex, and extending as a band 

 across the wing througli the upper half of the discal cell to 

 the posterior border and anal cell, also prolonged on the 

 third longitudinal vein and for one third of the length of the 

 fifth longitudinal vein. 



Dichelacera T-nigrum, ? , Fabr. 



One female from Santai'cm (Bates Coll.), 53. 72, with a 

 label attached bearing the name trijascia, evidently a MS. 

 name of Walker's. 



There is another female from the forest, Santarem, Lower 

 Amazons, 3. 96 (Austen Coll.), 96. 229, answering to the 

 description of this species ; but there are no brown spots on 

 the third segment of the abdomen, which is yellow with a 

 brown apex, and the thorax is more golden-haired than 

 brown-haired as Wiedemann states. 



Dichelacera marginata, ? , Macq. 



One female from Brazil (Bates Coll.), 49. 2; one female 

 from Para (Wallace & Bates Coll.), 50. 2. These were 

 descrilDed by Walker as D. hinnulus ; I cannot distinguish 

 which of the two is the type. One female from West Coast 

 of America, from Suiveying voyages of II.M.SS. 'Herald' and 

 * Pandora,' presented by Capt. Kellett and Lieut. Wood, 

 R.N., 50. 12. Two females from Ecuador, 1903, 74 (Rosen- 

 berg Coll.), presented by Mr. Theobald. 



The species described by Walker is apparently identical 

 with D. marginata ; the specimens from Ecuador are rather 

 larger and the abdomen darker coloured. Macquart's type 

 came from Cayenne. 



The wings, rather vaguely described by Macquart, are 

 liyaline, with the apex i'rom just below the base of the fork 

 of the third vein brown, which colour also extends over the 

 apex of the discal cell and as far as the fifth posterior cell, 

 and on the posterior border the apical cell is filled out with 

 brown, but is yellow at its extreme base; the fore border 

 is yellowish and the veins reddish yellow. Tlic third joint 

 of the antennse, wanting in Macquart's type, is here yellowish 

 at the base, brown on the upper half, the tooth long, reaching 

 to the second ring; the last four rings are nearly all equal, 

 with long hairs on the sides. 



Jjichelacera bifacies, ? , Walker.
