514 Me. J.B, Wellin’ Description of 
penultimate portion and slightly diverging from cubital vein. 
Squamae and halteres dark, the latter with a yellowish base to stem. 
©. Resembling the male but frons nearly twice as wide and very 
faintly shining. Abdominal tergites of more equal width throughout. 
Length barely 3 mm. 
One male and five females. 
[Two specimens, a 3 and 2, formed part of the material 
captured at Moor Plantation, near Ibadan, 8. Nigeria, 
Dec. 23, 1917, to Jan. 26, 1918, and sent to illustrate 
Farquharson’s notes in Proc. Ent. Soc., 1918, pp. xxx, 
xxxiv, xl. The remaining 4 2 9 were captured in the same 
locality, in May, 1918, on the evidence of a letter of May 28 
(see p. 445). They formed part of a set of “ absolutely 
guaranteed mendicants ” (pp. 445-46), soliciting food from 
Cremastogaster ants.—H.B.P.| . 
4. M. deetes, sp. n. 
Closely resembling M. prosaeles but wings without the 
brown streak along costa at base of wing, and thorax and 
abdomen more densely pubescent. 
3. Frons nearly double as wide as in prosaetes g and with the 
bristles (especially ocellar and vertical) longer. Thorax blacker, 
without the slight brownish tinge of prosaeles and with more 
numerous short hairs; notopleural depression and disc of scutellum 
with a greyish tinge in some lights; supra-alar bristles almost in a 
straight line. Abdomen with a distinct greyish tinge about the 
base of the second segment except at the sides; the short black 
hairs with which the abdomen is clothed very much more numerous. 
Tergites of moderate width throughout. Wings without any 
indication of the brownish costal streak of prosaetes. 
®. Resembling the male, frons only slightly wider than in pro- 
saetes 9. The greyish tinge about the base of second abdominal 
segment not so conspicuous as in the male. Slightly smaller than 
prosaectes. 
Two males and four females. 
[A single 2 formed part of the material of Dec. 23, 1917 
to Jan. 26, 1918, and the remaining 2 ¢, 3 9 a part of the 
series of “‘ absolutely guaranteed mendicants,” as described 
under M. prosaetes.—K.B.P. |
