Species XXXVI.— M. 7iotospilas , Wied. (Mon. Mid. pi. 54, fig. 20 ; Walk, in Linn. 
Trans. 17, 339.) Niger, thorace maculis 6 albis, abdominis fasciis pedibusque flavis.

Species XXXVII.— J\I. vittatus , Wied. (Mon. Mid. pi. 54, fig. 23.) Canus, thorace vittis 
nigellis, abdomine brunneo, albo-fasciato, antennis nigris, pedibus brunneis, femoribus pos¬ 
ticis haud spinosis, alis limpidissimis. Long. corp. lin. 6^ $. 
Habitat in Nubia. 
Obs. The veining of the wings in this species is similar to that 
of M. brevicornis ; the long closed central cell which runs parallel 
with the hind margin of the wing, not emitting the small transverse 
vein from near its apex to the hind margin. The small closed dis- 
coidal cell near the extremity of the wing, is also represented (Wied. 
fig. 23 d) as destitute of the short oblique spur which exists in all 
the other species, and which is in fact figured in fig. 23, and 23 a. 
Species XXXVIII.— M. lineotus, Olivier (Enc. Metb. tom. 8, p. 33). Niger, thorace cinereo 
4-lineato, pedibus abdomincque nigricantibus, hujus segmentis albis, antennis nigris, 
femoribus posticis lccviter spinosis vix incrassatis; alis pellucidis; venis nigris obscurius 
nonnihil inarginatis. 
Habitat in JEgypto, Sakbara; Olivier. 
Obs. —I do not think Oliviers description accords sufficiently 
with that of M. vittatus to induce us to regard them as descriptive of 
the same insect. If however identical, we must employ the name of 
lineatus for the species, instead of Wiedemann's name vittatus. 
Species XXXIX.— M. Olivieri , Macq. (Dipt. Exot. Nouv. t. 1, part 2, p. 12, Rkopalia 0.) 
Niger, pedibus rufis, facie capiteque subtus albo-pilosis, antennis nigris, scricie subgrisea 
indutis, clava maxima, thoracis lateribus supra originem alarum testaceis. Alis sub- 
fuscis. Long. corp. lin. 4-£. 
Habitat in AEgypto. In Mus. Reg. Paris. Olivier. An idem cum prsecedente? 
Obs. —The hind tibiae in this species terminate in two very minute 
spurs, scarcely visible. The wings agree with those of M. vittatus, 
in wanting the short appendiculated vein in the second submarginal 
cell, and in the absence of the short transverse vein in the middle 
of the hind margin.
