SOME ADDITIONAL REMARKS ON THE MASARID 
WASPS (HYMENOPTERA)

While my study of the Masaridinse was going through the 
press for the June 1929 issue of “Psyche”, two important 
papers have been published dealing with these insects. It 
seems worthwhile to consider in how far the new informa- 
tion they present agrees with the conclusions I had reached. 
A. v. Schulthess’ “Contribution to the Knowledge of 
African Masaridae” (May 1929, Ann. Mag. Nat. Hist., (10) 
III, pp. 498-511) contains descriptions of ten new species 
and one new genus. While it confirms what I had to say 
about the possibilities of future discoveries in this group, 
it does not call for any change in the map I gave of the 
general distribution of these wasps. Masariella (?) testa- 
ceopicta v. Schulthess is, I take it, the undescribed species 
of Jugurtia, from Northern Nigeria, which I mentioned in 
my paper. 
Three of v. Schulthess’ new species are placed doubtfully 
in Masariella , one of them being from North Africa, one 
from Northern Nigeria, and the third from South Africa. 
In how far these species are strictly congeneric with the 
genotype, M. alfkeni (R. du Buysson), is impossible to de- 
cide, since the mouth-parts are not described. While v. 
Schulthess rightly doubts that the relative development of 
the scutellum and postscutellum is sufficient to distinguish 
between Masaris and Masariella , his statement that “the 
most important criterion remains the number of the joints 
of the maxillary palpi (two in Masariella , four in Masa- 
ris) ,” must be due to an oversight. Bradley, who has made 
the most careful study of the mouth-parts of the Masari-
