This amber species has been doubtfully referred to the Iton- 
ididae, apparently being most closely allied to Heteropeza. 
Kieffer states that this species has a length of 1.1 mm, the borders 
of the wings being ciliate and the membrane not hairy; that the 
moniliform antennae have the funicle composed of 8 globose seg- 
ments and an oval terminal segment. The tarsi are quadriarticu- 
late. The typeisM. terminalis H. Lw.

This genus was erected for a unique female having at least I1 
and possibly 14 antennal segments, the fifth with a stem three- 
fourths the length of the cylindric basal enlargement, which latter 
has a length three times its diameter and has a short, rather thick 
basal, and a thick extended distal whorl of long, curved setae; 
circumfili absent. The palpi are quadriarticulate. The wings have 
3 long veins; subcosta with a rudimentary vein at the basal fourth 
somewhat as in Diallactes. A rudimentary crossvein appears to 
unite its distal third to’the third vein, the latter joining the wing 
margin probably well beyond the apex. The fifth unites with the 
margin at the distal third, its branch apparently at the basal half. 
The fork is therefore very short. The first tarsal segment is short, 
while the fifth tapers to the small, simple claws with rudimentary 
pulvilli. The ovipositor is rather short, triarticulate, the terminal 
segment slender, tapering and sparsely setose. 
The above: characters are drafted from the type species, H. 
plumipes Karsch, now in the Berlin Museum of Natural Hist- 
ory and very nicely mounted in balsam, thanks to the skill of Pro- 
fessor Rubsaamen. We agree with him in referring this form to the 
Heteropezinae.

This Argentine genus is tentatively referred to the Heteropezinae 
because of the total absence of circumfili. It appears to be allied
