Genus HELICONIAMYIA, new genus 

 Type species : Wyeomyia galoa Dyar & Knab. 



TABLE OF SPECIES 



(Coloration) 



1. Female with white on the mid tarsi ; bronzy shade on occiput 



very broad (male unknown) chalcocephala Dyar & Knab 



Female without white on mid tarsi ; bronzy shade on vertex 

 narrow galoa Dyar & Knab 



Heliconiamyia galoa Dyar & Knab (PI. V, fig. 5). 



Wyeomyia galea Dyar & Knab, Proc. Biol. Soc. Wash., xix, 140, 

 1906. 



Wyeomyia galoa Howard, Dyar & Knab, Mosq. No. & Cent. Am. 

 & W. I., ii, pi. 4, fig. 23, 1912.' 

 In the type, a diffuse bronzy median band on the occiput 

 is quite distinct ; the eyes have a narrow white border, though 

 it is obsolete at the vertex. The species should therefore be 

 placed in the coloration table in the Monograph in dichotomy 

 36 with the other //<?/;Vonfa-inhabiting species. The hind tarsi 

 of the female take a white reflection below on the last joint 

 only, but there seems to be no definite marking. In the male, 

 both the hind and mid legs are continuously white below. 

 The specimen mentioned below under onidus was originally 

 determined as galoa and quite properly with the coloration as 

 the sole guide. 



Heliconiamyia chalcocephala Dyar & Knab. 



Wyeomyia chalcocephala Dyar & Knab, Proc. Biol. Soc. Wash., 



xix, 140, 1906. 

 Wyeomyia chalcocephala Howard, Dyar & Knab, Mosq. No. & 



Cent. Am. & W. I., ii. pi. 8, fig. 27, 1912. 



The male genitalia seem indistinguishable from those of 

 galoa. Further material must be obtained to show whether 

 the two species have closely similar males or whether the male 

 of supposed chalcocephala is really a male of galoa. The 



'Figure 23 is bad ; the structure is shown better in figure 27. I 

 refigure it.
