A specimen received from G. Stuart Walley, said to have been 
reared from Fenusa pumila Klug, collected at Berthierville, Quebec, 
June 26, 1930, by L. Daviault, has been identified by A. B. Gahan as 
Cirrospilus pictus (Nees), a European species not previously recorded 
from North America. The host is a European sawfly, accidentally 
introduced, which mines the leaves of birch. 
J. C. Bradley and V. S. L. neces of the Department of Entomology, 
Cornell University, spent April 5 and 6 at the National Museum, ex- 
animing the collections of wasps of the families Scoliidae and 
Sphecidae, 
A wasp submitted for identification by Charles H, Hicks, Boulder, 
Colo., has been itentified by Grdce A. Sandhouse as a new species of 
the genus Tracheloides (Sphecidae), a genus not previously recorded 
from North America. Of the species previously described, two are 
from Europe and two from Africa. These wasps are predacious on ants, 
F, M. Setzler, of the Division of Archeology of the National 
Museum, recently brought back from Goat Cave, along the Pecos River, 
Tex., an unusually well-preserved Indian mummy which had the hair 
of the head loaded with lice, with their eggs. The lice have been 
identified by H. EB, Ewing as the head louse (Pediculus humanus 
americanus Ewing). Although the munny had been buried in ashes for 
several centuries the lice were fairly well preserved, Lice from 
pre-Columbian Indian mummies, of which several lots have been taken, 
are remarkably uniform and do not show the high degree of variation 
seen among the head lice of Caucasians, which represent largely 
hybrids between the true head louse and the body louse. 
It is of considerable interest to note that two economic species 
belonging to the very peculiar coccid genus Margarodes have recently 
been sent in to Dr, Morrison for examination, While comparatively 
little is known of the habits and biology of the members of this 
genus, they have hitherto, at least in the United States, been re- 
garded chiefly as scientific curiosities. One.of the species, which 
appears to be Margarodes meridionalis Morrison, described from Georgia 
and Florida, is now appearing on the roots of frasses in lawns in 
certain places in Arizona in immense numbers, and killing of these 
grasses is definitely attributed to the work of this insect. The 
second species, which is still unidentified spécifically, as the 
study material of the critical stages thus far received is too frag— 
mentary for accurate placing, is reported from the roots of citrus 
trees in Florida, This second species is evidently closely related 
to Margarodes rileyi Giard, known from the Florida Keys, and may 
ultimately prove to be this insect. 
J. Douglas Hood, of the Department of Biology, University oft, 
Rochester, spent several days in Washington early in April, working 
over certain species of Thysanoptera from the A. C. Morgan collection 
of these insects,
