ERIOPTERA lEMPEDA) NIGROLINEATA Enderlcin. 

 Empcda nigroUneata E.nderlein, Z(j61. Jahrb., vol. 32, 1912, ]ip. 5G, 57, fig. II'. 



The species is allied to E. stigmatica Osten Sacken, especialtyv in tlie 

 variety pubescens. This race differs in having the pubescence of the 

 wing, lack of the stiginal spot, and in color. Typical nigroUneata can 

 not be mistaken for stigmatica by its very striking coloration. 



A redescription of t^-]3ical nigroUneata, based on forty specimens, is 

 as follows: 



Male. — Length, 3-3.3 mm.; wing, 4.8-5 nmi. 



Female. — Lengtli, 3.9-5 mm.; wing, 5.1-6 mm. 



Head: rostnma and palpi diill yellow, the latter more brownish; 

 antennas brown; front, vertex, and occiput brown, the vertex paler, 

 yellow, in tJie vichiity of the eyes. 



Tliorax: light reddish-brown with a dark brownish-grey median 

 stripe, broadest on the pronotum, where the whole sclerite is hicluded, 

 narrowing behind, becoming indistinct before the suture. Tuber- 

 culate pits close together, separated by a distance about equal to the 

 diameter of one ; pseudo-suture pale, reddish, shiny. Lateral margins 

 of the praescutum pale yellow, scutum, scutellum and post-notum 

 light reddish-brown. Pleurae yellow, with a faint bluish tinge; no 

 stripes. Haltere light yellow, knob slightly darker, browniish. I^egs 

 dull yellow, the tarsi darker, j'ellowish-bro-ivn. 



Whigs liyahue; veins light brownish-yellow. 



Abdomen: light yellowish-red, base darker, brown: liA'jiopygium 

 yellow. 



I Jiave had for study a series of 49 specimens from the United States 

 National JIuseum collection. These were collected by G. Eisen, 

 Totonicipan, Guatemala, Central America, July, 1902. Forty of 

 these are referable to typical nigroUnfata; nine are referable to the 

 following variety: 



ERIOPTERA NIGROLINEATA, var. PUBESCENS. new subspecies. 



The head above is uniformly light grey, the dark stripe of the 

 tliroacic doreum broad, on the praescutum expanded out over tlie 

 entire sclerite \vith the exception of the anterior margin and the space 

 m front of tlie pseudo suture. Pleurae greyish with an indistinct 

 broad yellowish stripe above the foreleg and running caudad beyond 

 the whig basis: wings stiongly tinged with yellow at tiie bases: a 

 distinct. tJiouL'l! sparse, pubescence in all of the cells of the wings.
