SOME NEW AND INTERESTING SPECIES OF 
SAPROMYZA. 
By Cuar.es W. JoHnson.

The recent synopsis of the Sapromyzide by Prof. A. L. Melan- 
der (PsycuE, vol. XX, pp. 57-88, 1913), induced me to go over 
some material that had accumulated for several years. The 
results were something of a surprise. The series represented by 
the following species is what one would expect to find if he had 
only the two extremes, but the fact that practically all of the 
intermediate species really exist is doubly interesting. 
Two of the species suggest. the remarkable posterior tarsi of. 
Platypeza (Calotarsa), thus presenting an interesting case of 
parallelism. 
It is also interesting to note the wide distribution of some 
species and the apparently restricted distribution of others. Their 
similarity in size and color is probably one of the causes why 
these new species have been overlooked so long, and more careful 
collecting will undoubtedly show that these are more widely 
distributed than here indicated. 
Sapromyza ornatipes sp. nov. Pl. 3, figs. 1, 2, 3. 
Male: Face, front and antennz yellow, the front slightly darker than the face, 
arista black, base yellow, pubescence short. Thorax yellow, slightly pruinose, 
hairs black, with three dorso-centrals, scutellum yellow with four large marginal 
bristles. Abdomen dark yellow. Halteres and legs light yellow, posterior tarsi 
whitish, metatarsi with a row of short black bristles along the outer side and two 
long, curved, black subapical bristles slightly broader and flattened at the ends, 
the two following joints as broad as they are long, black, base white, thickly covered 
with black hairs and with two long curved bristles on each, similar to those on the 
metatarsi, the remaining joints brownish at the tips, with small black bristles and 
hairs. Wings hyaline, clouded with brown, the latter starting near the junction 
of the second and third veins and extending to a little beyond the anterior cross 
vein and along the costa from near the end of the first to the end of the fourth 
vein, with a partial interruption just beyond the end of the second vein, a band 
also extending across the wing covering the posterior cross vein. Length 3.5 mm. 
Female similar to the male except that the posterior tarsi are not differentiated, 
although the second and third joints are black.
