2iul Anal cell is entirely dark. Venation : Cell Isl M2 rectangular; 

 basal deflection of Cu\ a short distance beyond the fork of M. 

 Abdomen orange ; segments five to seven inclusive black. 



What the author consic^ers to be true longisfyla (since 

 it agrees in almost every respect with the brief type 

 descriptions) has been discussed in another paper (Psyche, 

 vol. 21, p. 39; 1914).

The brief description may be supplemented by the 

 following notes on Wiedemann's type. 



The abdomen of the holotype is entirely gone ; antennal 

 flagellum and all but a single leg lost. This single leg is 

 glued to the pin. 



Sex ( ?).— Wing 16-4 mm. Tibia 18-8 mm. 



The entire frons, vertex and dorsum of the occiput orange, the 

 ventral surface of the head brown. Antennae with the first scapal 

 segment orange, the second segment brov/n; flagellum broken. 

 Vertical tubercle conspicuous, Avith a very broad and low V-shaped 

 notch. 



The entire thorax is dark brownish black, no signs of stripes being 

 apparent in this century-old type. Halteres dark brown. Legs with 

 the coxae and trochanters dark brown ; the smgle leg that is glued 

 to the pin is very remarkable for an Eriocera, more resembling 

 certain species of Tre7Uepohlia and Tanypremna ; from its structure, 

 however, there can be little doubt but that it belongs to the insect as 

 described ; the femora are apparently yellow with broad black tips ; 

 tibia with the basal three-fifths (11 mm.) black, the apical tAVO- 

 fifths (7-8 mm.) white; metatarsus with a little more than the basal 

 half black, the remainder white ; second and third tarsal segments 

 white, the terminal segments a little darkened. Wings dark brown 

 with a conspicuous yellow cross- band at the level of the cord, this 

 including the end of cell C, intermediate portion of \st R\, bases of 

 cells RZ, 1st M2 and Cu\, and apices of cells R and M. As stated 

 by Wiedemann, the Anal cells are a very little paler than the re- 

 mainder of the wing, but this is not at all conspicuous ; veins dark 

 brown, paler in the yellow cross- band. Venation : Sc\ alone about
