Mandible shown in figure 3. Punctulation of head a trifle 
coarser than in holotype, but not closely approaching that 
of the foveolatus types; specimen rather dirty, of dullish 
coloration. 
The paratype series has been returned to the collection 
of the U. S. National Museum. Ps. lucidus as presently 
conceived may be separated from the related foveolatics 
by the striking sculptural difference as well as by the prob- 
ably less reliable characters of size, head shape, color, etc. 
Discovery of Psilobethylus males in association with fe- 
males on this continent will probably lead to revision of 
the status of the forms here included in lucidus. 
We wish to offer our thanks to Mr. Muesebeck and Dr. 
Bonet for their aid in sending material and in furnishing- 
other information used in this paper. 
Some Notes on Synonomy of the Mycetophilidae (Dip- 
tera). — In 1940 (Revista Ent., 11 :803-808), the author 
described several new species of Mycetophilidae from Costa 
Rica. Among these was included Neoempheria neivai. This 
publication appeared in December. Without the knowledge 
of the author, Dr. F. W. Edwards of the British Museum 
described some species of Neoempheria , including a Neo- 
empheria neivai (Nov. Zook, 42:107-129). This paper ap- 
peared in April, 1940, and hence Edward’s specific name 
neivai has priority. At this time I would like to rename 
my Neoempheria neivai and will substitute the name phil- 
lipsi for neivai. This name is selected in honor of Dr. E. F. 
Phillips whose untimely death during the past summer is 
greatly mourned. 
During the current year, 1951, the author published des- 
criptions (Bull. Brooklyn Ent. Soc., 46:65-70) of new 
Mycetophilidae from western United States. In these was 
included a new species which I named Exechia ligulata. 
Laffoon, in correspondence, has recently indicated that the 
name ligulata was a homonym having been used by Lund- 
strom in 1913. Hence I will substitute the specific name 
subligulata for my ligulata. F. R. Shaw, University of
