Some specimens have a short stump of a vein near the origin of the radial 

 fork. 



6th Section. 



Antennae short, hardly reaching the basis of the wings ; the four basal joints 

 of the flagellum are short and almost coalescent, forming an elongated, subcylindri- 

 cal body, which is stouter than the remaining part of the antennoz ; the following 

 joints are subcylindrical, with short verticils. Wings narrow in the <$, a 

 little broader in the 9 neuration somewhat like Meig. i. tab. vi. f. 2. Feet 

 slender. 



L. ultima. Cinerea, antennis fuscis, thorace vittis quatuor fuscis, inter- 

 mediis approximatis, pedibus infuscatis, alis pallide cinerascentibus, stigmate 

 pallido ; long. 2|-3 lin. 



Cinereous, antennae and palpi brown, first four joints of the flagellum as 

 described above ; thorax with four brown stripes, the intermediate approxi- 

 mated, the lateral ones abbreviated before ; halteres slightly infuscated at tip, 

 feet fuscous ; coxae cinereous ; trochanter and base of femora pale ; $ forceps 

 of the same brownish cinereous color as the body ; basal joint of forceps long, 

 cylindrical ; horny parts elongated, hooked at the tip, (fig. 26.) Ovipositors 

 moderately long, very slightly curved.

7th Section. 



(Subg. Epiphragma nob.) 



Wings broad, variegated with brown bands, spots, ocelli, etc. ; neuration 

 somewhat like Meig. vol. i. tab. iv. f. 20, but ivith a supplementary cross-vein in 

 the subcostal area, about the middle of the anterior margin, (as in Schum. tab. iv. 

 f. 3.) Antennfe not reaching much beyond the base of the wing; 1st. joint 

 cylindrical ; 2d short, cyathiform ; 3c? and 4th coalescent, stout ; the 5th and 

 the following slender, elongated, slightly incrassated at their base, with moder- 

 ately long verticils on the incrassation. 



The European L. p i c t a belongs to this section. 



L. solatrix. Brunnea, articulo antennarum tertio flavo, thorace pone 

 alas pallide sericeo, ake fusco et testaceo-pictae. Long. lin. 4. 



Proboscis and palpi brown ; basal joints of the antennae dark cinereous ; 

 the second dark brown ; the third yellow ; the following dusky, darker towards 

 the tip ; front and vertex brown, sericeous with yellowish ; margins of the 

 eyes paler. Collare brown ; praescutum reddish brown, two brown stripes in 

 the middle ; lateral stripes abbreviated and indistinct ; dark brown spots on 

 the humeri ; the posterior margin of the praescutum, as well as the scutum, 

 scutellum and metathorax are yellowish white, sericeous ; anterior part of the 

 pleurae dark brown with some pale and sericeous lines ; posterior part serice- 

 ous ; halteres pale, tip of the knob brown ; feet pale tawny clothed with short 

 hairs ; coxae sericeous, with brown in the middle ; a brown ring before the tip 

 of the femora. Abdomen pale brown, clothed with short hairs ; anterior mar- 

 gin of the segments darker, posterior margin whitish-sericeous ; 9 ovipositor 

 ferruginous. Wings variegated with brown and tawny ; the subcostal area 

 contains two angular brown marks, besides the two infuscated cross-veins 

 (humeral and supplementary) ; a large spot is situated at the base of the 

 wing, between the subcostal vein and the posterior margin ; its anterior part 

 is tawny, the rest brown ; a brown band begins at the posterior margin, before 

 the tip of the axillary vein ; it extends to the pnebrachial vein, where it as- 

 sumes a tawny color and emits two branches ; one branch joins a tawny spot 

 in the prsebrachial area (between the two angular marks of the subcostal area) ; 

 the other branch joins a large brown spot which occupies the greater part of
