307 Die Bienen Afrikas nach dem Stande unserer heutigen Kenntnisse. ,gq 



Mandibles with 2 bluntly rounded teeth, 2 smaller than the i., behind the 2., tooth the}' are broadly slightly 

 rounded dilated; their middle deeply, widely grooved, the groove widest at the apex; outside it, on the apical 

 half is a narrower furrow. Head closely, strongly punctured, less closely in the centre of the clypeus, which 

 has its apex depressed and clearly separated, it is transversa. Thorax closely, strongly punctured; metanotal 

 area coarsely aciculated. Abdomen closely punctured above, without transversa furrows; apical joints and the 

 under side of the basal of the fore tarsi are tastaceous, hair on the legs cineraous; spurs pale testaceous, base 

 of metatarsus Vs of the width of the tibiae, metatarsus slightly shorter than tha other joints united. Mandibles, 

 inside the furrow, baar elongata, large punctures; they are sparsely covered with pale hair. 



Transvaal. 



This species comes close to M. robertiana, which may ba known from it by the basal half of the mandibles 

 being densely covered with grey pubescence, apical furrows are much less clearly defined, apical 2 teeth more 

 äqual in size, apex of the clypeus not transversc in the middle and its sides roundly waved; the hair is denser 

 and longer both on the body and legs; and on the under side of tha tarsi it is bright red.

A quelque ressemblance avec M. felina Gerst., mais est plus petite et a le chaperon plan.

Ekuiva Valley, W. Africa, at flowers of a native species of mint, collected {1907) by Dr F. Creighton 

 Wellman. The specific name means black and red in the language of tha Sula Islands. 



Anothar species of Creightonella, differing by the colour of the hair on the tarsi and ventral abdominal 

 segments, etc., has bean described by Friese (Zeitschr. f. Hym. Dipt., 1903, p. 273) as M. sexdentata. Unfort- 

 unately this name was used by Robertson in 1895 for an American species, so it will have to be changed. 

 M. mandihulata Smith, is also perhaps a Creighlonella, but this cannot be dcfinitely determined without an 

 examination of the types.
