HEÏEROCHROA PICTIPENNIS. 91 



A 9 from Chili (Dolirii). It agrees well enough with 

 Schiner's description of the cf to allow of its identifica- 

 tion with this species. The scutellum has a black spot on 

 each side, which is a continuation of both lateral stripes 

 of the thoracic dorsum. 



In the genus Heterochroa the costal vein does not end , 

 as is usual in the family of the Muscidae , at the orifice 

 of one of the longitudinal veins at the wing tip , but it 

 surrounds the whole hind-border of the wing , though be- 

 coming thinner beyond the cubital vein. 



Schiner arranges this genus in the group of the Geo- 

 myzinae, and describes, besides the above mentioned spe- 

 cies, still another which he names ff. hicolor. The Leyden 

 Museum contains a third species, which is from Chili as 

 are both the others ; although it is represented by a single 

 female specimen, I will describe it, because it can easily 

 be distinguished. 



27. Heterochroa pictipenn is, n. sp. 



Ochracea; vitta frontali unica, vittis thoracis sex cum 

 fasciis abdominis uigro-fuscis; femoribus annulo subapicali 

 fusco ; alis fusco- et albo variegatis , basi flavescente , ner- 

 vis transversal ib us colore fusco non obtectis; nervorum

 9 long. 5 mm. 



Ochraceous. Front with a narrow darkbrown longitu- 

 dinal stripe , ending in a point before it reaches the an- 

 tennae; face with a whitish reflexion , the ridges on both 

 sides very narrowly margined with black. Second joint of 

 the antennae with a rather long black bristle; the arista 

 also black and provided with microscopic hairs (in picta it 

 is more distinctly plumose). Thorax on the upperside with 

 two distant black longitudinal stripes , not reaching the front 

 margin , but continued backwards as a lateral border of the 

 scutellum ; on both sides a similar stripe from the shoul- 

 ders down to the root of the wing , and on the under-
