ERIOCEKA. 11 



Head, including the rostrum and antennae, yellow ; palpi brown. Besides the three 

 black stripes on the thorax there are some blackish and brownish marks on the pleurae. 

 Knobs of the halteres brown, the stem yellow. The posterior half of the first abdominal 

 segment is black ; in the male the posterior half of segment 5 and the whole of segments 

 6 and 7 are also black, in the female the posterior half of segment 5 and segment 6 only ; 

 the rest of the abdomen, and the genitals, yellow. Legs yellow, the tips of the femora 

 black ; tips of the tibiae, and the tarsi entirely, brown. Wings with a pale yellowish- 

 brown tinge, more yellowish along the costa ; the tip of the auxiliary vein does not 

 reach much beyond the proximal end of the second posterior cell ; this tip is incurved 

 towards the first vein ; there are four posterior cells ; the great cross-vein anterior to the 

 middle of the discal cell. 



A male and a female (coll. Bellardi). 



N.B. — This description was made several years ago, and 1 have not now the types 

 before me. A female specimen from Zapote, Guatemala (Champion), agrees with it ; 

 but the four basal joints of the antennae only are yellow, the rest black. The stout 

 auxiliary vein shows the same peculiar course ; it seems to end in the first vein, but 

 has a delicate cross-vein at the tip, connecting it with the costa. Two specimens from 

 Irazu, Costa Rica (Bogers), show the same characters, but in one of them the whole 

 abdomen is blackish (in the other specimen it is broken). 



3. Eriocera haemorrhoa, sp. n., <? $ . 



Black, except the frontal tubercle, the part of the thoracic dorsum anterior to the suture, and the tip of the 



abdomen, which are orange ; wings fuliginous. 

 Length : rf , 14-17 millim. ; $ , 17-20 millim. 



Hab. Mexico, Orizaba (Sumichrast). 



There is but little to be added to the diagnosis : — The orange colour on the thorax 

 occupies the whole of the space between the suture and the collar. The abdomen is 

 velvety-black, but the anterior half of each segment, above, is bluish-black and shining ; 

 in the male the third and fourth segments show traces of reddish-yellow at the base ; the 

 last segment is orange. Halteres and legs black. The tip of the auxiliary vein is 

 nearly opposite the proximal end of the first submarginal cell ; the great cross-vein 

 anterior to the middle of the discal cell, sometimes at its base ; there are four posterior 

 cells. 



Three males and as many females (coll. Bellardi). A female in M. Bigot's 

 collection. 



4. Eriocera erythraea, sp. n., <j $ . 



Black, the thoracic dorsum, including the scutellum, orange ; wings fuliginous. 

 Length : <$ , 13 millim. ; $ , 17 millim. 



Hab. Guatemala, San Geronimo (Champion). 



Head, including the antennae and palpi, black ; front slightly greyish-pruinose. Thorax
