S78 REPORT OF THE HARVARD AFRICAN EXPEDITION 
Bowvieromyia Strand, 1928, Arch. f. Naturgesch., XCII, (1926), Abt. A, Heft 4, p. 78. New name 
for Bouvterella Surcouf, 1909, not of Chevreux, 1900. 
Most of the species formerly placed in Bouvierella appear to belong in T’ri- 
clida. Of the described species only two remain in Bouvieromyia, the genus 
being then restricted to Madagascar. 
Aegophagamyia Austen 
Aegophagamyia Austen, 1912, Ann. Mag. Nat. Hist., (8), IX, p. 12. Type by original designation: 
Aegophagamyia pungens Austen, 1912. 
Aegophagomyia Aders, 1917, Bull. Ent. Res., VII, p. 398. Enderlein, 1925, Mitt. Zool. Mus. 
Berlin, XI, 2, pp. 325 and 326. 
Seven species have been described in this genus, which is almost restricted 
to Madagascar and some of the islands in the Indian Ocean. One species is 
found in Zanzibar and Pemba Island, as well as on the coast of Kenya Colony. 
Enderlein transfers Bouvierella flava Sureouf to Aegophagamyva and, if this 
procedure were to be followed, Bouvierella interrupta Bezzi would likewise be 
placed here, at least on the strength of the wing venation. I doubt, however, 
that the relative lengths of the stalks of the first and fourth posterior cells are 
of generic or even of specific value. Bouveromyia, Triclida, and Aegophagam- 
yva appear to be very poorly defined as genera. Bouvieromyia inornata (Austen), 
of which I have seen at the U. 8S. National Museum a female from Glorioso 
Island (W. L. Abbott), combines the slender proboscis and wing venation of 
Aegophagamyia with the frontal callosity of Bouvieromyia. This species, as 
Austen recognizes, is an annectent link between the two genera. 
Rhigioglossa Wiedemann 
Rhigioglossa Wiedemann, 1828, ‘Aussereurop. Zweifl. Insekten,’ I, p. 105. Monotypie for Rhigio- 
glossa testacea Wiedemann, 1828 = Rhinomyza edentula Wiedemann, 1828. J. Bequaert, 1924, 
Psyche, XX XI, p. 30. 
Erodiorhynchus Macquart, 1838, ‘Dipt. Exot.,’ I, 1, p. 110. Monotypic for Hrodiorhynchus 
eristaloides Macquart, 1838 = Rhinomyza edentula Wiedemann, 1828. Enderlein, 1925, 
Mitt. Zool. Mus. Berlin, XI, 2, p. 308. 
Scarphia Walker, 1850, ‘Insecta Saundersiana,’ I, Dipt., p. 10. Monotypic for Pangonia directa 
Walker, 1850 = Rhinomyza edentula Wiedemann, 1828. Enderlein, 1925, Mitt. Zool. Mus. 
Berlin, XX], 2, p: 325. 
Metoponaplos Ricardo, 1915, Arch. f. Naturgesch., LX XX, (1914), Abt. A, Heft 8, p. 124. Mono- 
typic for Pangonia parva Walker, 1848 = Rhinomyza edentula Wiedemann, 1828. 
The earliest valid name for this genus is Rhigioglossa, used by Wiedemann 
for a synonym of his Rhinomyza edentula. It appears to be a strictly South 
African group, represented by two species: R. edentula (Wiedemann) (= Rhi- 
nomyza edentula Wiedemann, 1828; Rhigioglossa testacea Wiedemann, 1828: 
Erodiorhynchus eristaloides Macquart, 1838; Pangonia parva Walker, 1848: 
and Pangonia directa Walker, 1850) and R. nigricans (Ricardo). I am not 
positive, however, that the last-named species is strictly congeneric with R. 
edentula. 
Enderlein places Hrodiorhynchus and Scarphia in different subfamilies, the 
former in his Silviinae, the latter in his Searphiinae. These, however, are sepa-
