scutellum projects considerably behind the scutellum, the mes- 
episternum is not divided by a suture, and the parapsidal furrows 
are absent. Since, according to Brauns, Masaris discrepans 
Brauns is exceedingly close to M. saussurei Brauns, there can be 
little doubt that all South African species thus far placed in 
Masaris are more correctly placed in Masariella, as was suspected 
by Bradley. 
Having had an opportunity to study the female of Trimeria 
buyssoni Brethes, I may add a few notes on the generic characters 
in that sex. I suspect that some of the characters given for the 
male by Bradley (1922, Univ. California Publ., Ent., I, No. 9, p. 
433) are of specific value only. In the female of T. buyssoni , the 
ocelli are placed in a flattened (not in an equilateral) triangle; 
the antenna consists of 12 segments, the flagellum being uni- 
formly incrassate throughout, without apical club; the parap- 
sidal furrows are absent; the anterior trochanter ends in an 
obtuse, narrow lobe, which, however, does not project beyond 
the lower margin of the femur; the anterior femur is swollen and 
flattened as in the male, but not angled at the base; the middle 
femur is flattened beneath; both the last tergite and ste'rnite are 
obtusely pointed at apex, the sternite thickened along the margin 
and depressed on the disk. I find the larger posterior tibial spur 
trifid (not bifid as given by Bradley). 
Trimeria buyssoni is the only species of Trimeria which I 
have been able to study. So far as one can judge from the rather 
incomplete published accounts, the genotype, T. americana (H. 
de Saussure), and the three other described species, T. neotropica 
(Mocsary), T. joergenseni Schrottky, and T. howardi Bertoni, are 
congeneric with T. buyssoni. Of these five species only three 
appear to be distinct upon morphological characters, viz., T. 
americana, T. buyssoni, and T. neotropica. It would seem that 
T. joergenseni is but a color variant of T. buyssoni, while there is 
nothing in the description of T. howardi (apart from differences 
in coloration) to allow of its separation from T. neotropica.
